两种石灰稻壳灰水泥的标准稠度,较硅酸盐水泥标准稠度大得多,这是碳化稻壳有特大的比表面积,而引起标准稠度的增加

碳化稻壳有以外掺或内掺形式掺入商品混凝土


三、碳化稻壳水泥商品混凝土

碳化稻壳有以外掺或内掺形式掺入商品混凝土,在等量取代20%水泥的情况下掺稻壳灰试件,3d、7d抗压强度均小于未掺稻壳灰的空白组,但28d抗压强度较空白组增加20%,说明稻壳灰具有较高的火山灰活性,在超量取代水泥的情况下,稻壳灰的增强效果更显著。稻壳灰以外掺形式掺入商品混凝土的技术条件及结果,掺稻壳灰的试验组抗压强度提高的幅度较大,且早期比后期强度高,表明稻壳灰有强烈的增强作用,与硅灰相似。【具体可参考《碳化稻壳优势明显应用价值毋庸置疑》的相关内容】
