ABSTRACT

This research is intended to investigate the effect of recycled aggregate concrete and various types of cement which are OPC, PCC and PPC due to sulphuric attack The concrete resistance to sulphuric attack is indicated by compressive straight and concrete deterioration.

Each type of cement was mixed into three dosagesof recycled aggregate 0%, 25% and 100% as replacement of natural coarse aggregate. The specimen test is cylinder form 7.5cm in diameter and 15cm in high. The 27 samples were tested by immersion test while 9 others without immersion test.The researcher has cured 27 concrete samples in (H2SO4) 5% and the other concrete samples cured by air. After 28 days of age, the compressive strength test for both the samples which immersed in solution and by air was conducted. The process continued to the renewal of solution and measuring weights and diameters of the other samples in the solution every 2 weeks. After 56 days of age, the compressive strength test was conducted. Finally, the small portions of the surfaces and core of the samples were tested using XRD.

It is noticed from compressive strength result the samples which cured by air gave better result than others which cured by solution. The higher percentage of recycled aggregates in the concrete means the less in compressive strength and less in resistance to acid attack. It is noted that mixtures which contain PPC are the most resistant to acid attack. Mixtures which contain PCC rank number two related to the resistance to acid attack. The mixtures which contain PPC have retained their size throughout the duration of curing.

ABSTRACT

Penelitian ini bermaksud untuk meneliti pengaruh recycled aggregate concrete dan berbagai tipe semen, yakni OPC (Ordinary Portland Cement), PCC (Portland Composite Cement), dan PPC (Portland Pozzolan Cement) dikaitkan dengan

―serangan‖ asam sulfur, terhadap compressive strength dan concrete deteroration.

Untuk setiap jenis semen; dibuat campuran menggunakan recycled aggregate dalam 3 dosis berbeda, yakni 0%, 25%, dan 100%. Untuk pelaksanaan compressive test dan submerssion test, dibuat cetakan bentuk cylinder berdiameter 7,5 cm dan tinggi 15 cm. Immersion test dilaksanakan terhadap 27 sample, sedangkan untuk sisanya sejumlah 9 sample tidak dilaksanakan. Peneliti mengawetkan 27 sample concrete itu dalam (H2SO4) 5%, sedangkan lainnya diawetkan dengan udara. Setelah genap 28 hari usia sample concrete tersebut, dilaksanakan compresive strenght test terhadap sample-sample tersebut; baik yang diawetkan dalam larutan maupun yang diawetkan di udara. Proses dilanjutkan dengan memperbaharui larutan dan kemudian mengukur berat dan diameter dari sample-sample yang lain setiap dua pekan. Setelah usia sample-sample concrete itu genap 56 hari; maka dilaksanakan compressive strenght test. Akhirnya, sebagian kecil dari permukaan dan inti dari sample-sample diuji menggunakan X-Ray Diffraction

Dapat dilihat bahwa sample-sample concrete yang diawetkan di ruang terbuka memberikan hasil yang lebih baik dalam compressive strenght; dibandingkan sample-sample yang diawetkan dalam larutan. Semakin besar persentase recycled aggregate dalam concrete mix ternyata menunjukkan compressive strenght yang lebih lebih rendah, dan juga menunjukkan kekuatan resistensi yang lebih rendah terhadap acid attack. Tercatat bahwa concrete mixture yang mengandung PPC paling resisten terhadap acid attack. Sedangkan concrete mixture yang mengandung PCC berada di urutan kedua resistensinya terhadap acid attack. Concrete mixture yang mengandung PPC bentuknya tidak mengalami perubahan selama proses pengawetan
