Effect of Different Cooling Method Due to the Width of

Reinforced Concrete Beam Burned in High Temperature

M t h i f t lli d i fi i fl h d l d l t l Th d l t f thi

Many techniques for controlling or decreasing fire influence has developed lately. The development of this phenomena and dinamic of fire influence has carried out as on building protection and prediction of building ability for holding fire. The existence of influence on heating and cooling process caused the concrete

structure will be wider crack for longer time and the concrete structure will be collapse by the end. Some experiments had conducted with variety temperature and different watering process. It was intended to observe how far their influence to crack width and in further it was known that the concrete structure can still be used or not after burning process.

Concrete is a composite material and based on previous experiment presented that high temperature of 2000C did not decrease the srong pressure because there was fast treatment phenomena or accelerated curing [1]. Hansen [2] described that there was some increasing on strong pressure of concrete if it was

heated in the temperature of 200-3000C, but it was more than 80% increasing of the first strong pressure if it was heated until 4000C and 30% if it was heated until 7000C

was heated until 4000C and 30% if it was heated until 7000C.

Partowiyatmo [1] had found a process to fix the breaking concrete caused by burning. He suggested process of watering. This process intended to obtain the recovery of strong burning concrete so that the water

The Characteristics of Rice Husk Biochar and Its Influence on the

Properties of Acid Sulfate Soils and Rice Growth in West Kalimantan

• 1. Introduction

• Increasing food production both to meet in-country requirements and to help the world overcome food crises is one biochar, soil amendment, acid soils, rice straw, soil strength, CEC of the major issues facing Indonesia today. However, good productive land is limited and has mostly been utilized either for food crop production or other uses. The only available land for this purpose is that of acid sulfate soil, having a total area of about 6.7 millions ha and is spread out in Sumatera, Kalimantan, and Papua (Widjaja-Adi et al., 1992) These soils have a high iron sulfate mineral content of predominantly Pyrite and when the soil is 1992). These soils have a high iron sulfate mineral content of predominantly Pyrite, and when the soil is drained it will release sulfuric acid, which in turn will release Fe, Al, and other heavy metals that are

dangerous for plants and other living organisms. When these soils are used for rice, Moore (1990) found that the most important constraints were: (i) acidity (which includes the combined effects of pH, Al toxicity, and P deficiency), and (ii) Fe stress (which is due to the combined effects of Fe toxicity and deficiencies of other divalent cations such as Ca).

• A common treatment to reduce the solubility of Al, Fe and other heavy metals in soil is to increase the soil pH, which is mostly done by liming (Ahmad and Tan, 1982; Hakim et al., 1989; Haby, 2002). The ability of liming to increase soil pH, decrease Al and Fe solubility, and increase crop yield is widely known

(Shamshuddin and Auxtero, 1991; Haby, 2002; Kadery, Brown et al., 2008). In Indonesia, the source of lime materials exists mostly in Java, which is far from the location where the liming needs to be done. Furthermore, liming only treats the symptoms of acid sulfate soils rather than the cause (Thomaset al., Furthermore, liming only treats the symptoms of acid sulfate soils rather than the cause (Thomas et al., 2003); therefore, the beneficial effects of liming are short lived, and it has to be done repeatedly

(Shamsuddin et al., 1998). This makes liming very expensive and it is often un-economic for small farmers to obtain lime materials.

• Lately, looking the recalcitrant C-organic in a black carbon material termed “biochar”, and lately many scientists are interested in using this black carbon material as a soil amendment (Glasser et al., 2002;

T li t l 2007 W lf 2008) Alth h th till bj ti (E ti d S lk 2009

Topolianz et al., 2007; Woolf, 2008). Although there are still some objections (Ernsting and Smolker, 2009; Senjen,2009), a lot of experimental results have indicated that biochar applications can improve soil

properties (Lehman et al., 2003; Liang et al., 2006; Chan et al., 2007) and increase crop yield (Yamato et al., 2006; Chan et al., 2008 ). Chan et al. (2007) showed that biochar application had improved some

physical soil properties, such as increased soil aggregation, water holding capacity, and decreased soil strength. An increase in saturated hydraulic conductivity of upland rice soilg y y p

• Materials and Methods

• The purpose of this study was to observe the effort to decrease concrete crack width which was caused by normal temperature or high temperature on cooling condition which was caused by normal temperature or high temperature on cooling condition without and with watering in certaint time. The variety temperature was 200°C, 400°C, 600°C and observation was during 28 days.

• The influence of temperature in concrete block

• Riley, 1991 in Gani [3] said that crack would happen inside the mortar (pasta of t) d d th t f ti l t th t t b t 300 t 5000C cement) and around the agregate of particle at the temperature between 300 to 5000C, while temperature of 300oC was as the limit of crack which happenned around the

agregate of particle.

• Last report about test of building material after burning presented that the breaking structure of concrete element would become worse after burning results if there was g apalling or getting peeled of concrete blanket. Concrete has increased the temperature for heating, so water is contained in the holes and the concrete capilarry will be

stronger at temperature of 100oC for some water and calcium silicate (CaSi) as the lack of water in cement pasta will disapear. It followed the lack of power. The increasing on number of vapour pressure in the holes caused explosive spalling that is part of p p p p g p concrete segment release from the surface and it happens at the temperature of 300 to 600oC. The next release will gradually be happened because there is formation of

concrete that will became weak and brittle at the temperature of 6000C. • Proof of strengthening concrete due to high temperature

• Concrete was proved having ability for keeping its integrity and strength from time • Concrete was proved having ability for keeping its integrity and strength from time

to time [5]. At burning temperature, hot condition that was received by concrete in the surface was different with in the middle one. So the breaking degree of concrete

• To ensure that the rice husk had come from the acid sulfate soil of West Kalimantan, Indonesia, we h t d it di tl th i f th fi ld d th b ht it f i illi t t th i h k Th i harvested it directly the rice from the field and then brought it for rice milling to get the rice husk. The rice husk was then put in a piece of pyrolysis apparatus which consisted of a stainless reactor of 500mm length with a 15cm inside diameter. The rice husk was then heated externally by an electric furnace (5000 W) to a temperature of 600oC. The reactor for the biochar production is presented in Figure 1.The Biochar was ground to pass through a 0.50 mm sieve……

• A glass house experiment was set up to study the effect of rice husk biochar on rice growth. The soil used was collected from the experimental station of BPTP West Kalimantan in Sungai Kakap. Soil

samples were collected from depths of up to 20cm, and then dried, ground, and passed through a 2.0mm sieve. 5kg of ground soil was then put in a plastic pot with an inside diameter of 30cm. The organic soil amendments used were:

• These six treatments were arranged in Fully Randomized Design with 4 replications. The amount of soil amendment applied was calculated based on the surface area of the plastic pot, and the amendments were mixed to a 20cm depth, after which they were incubated at water content close to the field capacity for 30 days. y

• 2.3. Soil Analysis

• Particle size analysis was performed by the pipette method (Soil Survey Laboratory Staff, 1992), and soil bulk density was determined by the clod method as described by Blake and Harke (1986). Soil pH was measured in 1:2.5 ratio soil solutions (with de-ionized water) with a pH meter (Jenway 3305). The

Walkley and Black wet oxidation method was used to determine organic C content (Soil Survey

• Results and Discussion

• The effect of rice husk biochar and other soil amendments on the chemical properties ofThe effect of rice husk biochar and other soil amendments on the chemical properties of acid sulfate soil in West Kalimantan is presented in Table 3. In general, application of organic soil amendments significatly improved the chemical properties of acid sulfate soil. There was an increase in soil organic matter content, soil pH, and CEC and a decrease in exchangeable Al and soluble Fe. The results in Table 3 also show that application of

organic soil amendments increased the level of P, K and Ca, but did not significantly organic soil amendments increased the level of P, K and Ca, but did not significantly influence the amount of Mg and Na.

• Table 3

• Rice husk ash and rice husk biochar had a high pH (Table 1); therefore, it is reasonable that the soil treated with rice husk biochar and rice husk ash also had a high pH. This

results indicated that rice husk biochar could be used as a substitution for lime materials to increase the pH of acidic soils. The increase in CEC of the soil with organic soil

amendments would probably be due to the negative charge arising from the carboxyl p y g g g y

groups of the organic matter. The increase in CEC and soil pH with the addition of organic matter has been shown elsewhere (see Bot and Benites, 2005). Biochar has a high CEC (see Table 1), and with its high recalcitrance (Glaser et al., 2002), it is reasonable that soil applied with biochar had the highest CEC. An increase in soil CEC with the application of biochar has also been shown by Chan y et al. (2007)( )

sulfate soil had a characteristics of ………..

•

Application of rice husk biochar and other organic soil amendment

applications improve some properties of the acid sulfate soil of West

Kalimantan, Indonesia, namely: decreasing soil bulk density, soil

strength, exchangeable Al, and soluble Fe, and increasing soil pH, soil

organic matter total P CEC exchangeable K and exchangeable Ca

organic matter, total P, CEC, exchangeable K, and exchangeable Ca.

•

The improvement of soil properties with organic soil amendment

applications resulted in an improvement of rice growth as shown by an

increase in plant height, number of tillers, and dry biomass. A significant

negative correlation occurred between dry biomass and exchangeable

Al, soluble Fe, and soil strength; and a significant positive correlation

occurred between dry biomass, soil organic matter, and total P.

•

Fire disaster on building structure at some big cities is still happened due to

that fire is one of high risk failure of structure. Fire can be as a burden

thermal which did not want and be hoped on structure buiding, and the

temperature has tendency so high and increasing in a short time. There is

influence of hot cycle and fast cooling will cause the concrete structure

crack and become wider until the concrete structure will be collapse at the

end. This study discussed about the power of concrete structure especially

the comparison of wide crack of reinforced concrete beam and natural

concrete beam due to higher temperature of fire with the difference cooling

process and watering. The methodology consisted of experiment using

cooling process as normal watering process (or cooling without watering)

and cooling by watering. This experiment was carried out by trial kinds

temperature of 200°C, 400°C, and 600°C with factor of cement water was

steady in 28 days and then carried out watering process after the concrete

was burned until 1000°C with dimension of 1m x 1m x 1m. The next step

was cooling without and with watering for the block with the dimension of 75

cm x 15 cm x 15 cm. Crack Detector Microscope was used to detect crack

width in every burden of LCD adding. Results showed that there was
