Hydration Study Of Rice Straw Ash Admixtured Cement Using Ftir And Sem

Abstract:Rice straw ash is used as a mineral admixture to cement in the present study. Rice straw is collected fromlocal paddy field and burnt in a clay pit . The ash was collected and grounded to a fine powder. The grounded ashwas sieved using a 75 µm test sieve and replaced partially with cement at 5%, 10%, 15% and 20% by weight. Theadmixtured samples were hydrated for 1hour to 4 weeks and FTIR , SEM, and compressive strength analysis werecarried out. The results were analyzed in the light of available literature.

摘要：本研究将稻秆灰用作水泥的矿物掺合料。研究从本地稻田采集稻秆，于黏土坑内进行焚烧。收集所得的灰分经研磨制成细粉，再通过75 µm试验筛筛分，并以5%、10%、15%、20%的质量取代比例部分替代水泥。将掺合后的样品水化养护1小时至4周，并开展傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）以及抗压强度测试分析。本研究结合现有文献对试验结果进行了分析。
