碳化稻壳替代水泥掺入混凝土,能明显的改善孔结构,孔隙明显细化,小于20nm的无害孔明显增多


碳化稻壳替代水泥掺入混凝土,能明显的改善孔结构,孔隙明显细化,小于20nm的无害孔明显增多。而且几孔径和平均孔径越小,混凝土的抗压强度越大,用平均孔径能较好地表示碳化稻壳混凝土孔参数。对不同的水胶比,掺10%和20%高活性稻壳混凝土都具有良好的抗冻融特性,但是掺30%稻壳的混凝土的抗冻融特性下降;混凝土含气量和平均气泡间隔系数极大的影响混凝土的抗冻融特性,硬化后含气量为4.5%和平均气泡间隔系数为400微米以下的碳化稻壳混凝土都具有良好的抗冻融特性;从混凝土的抗冻性角度来看,高活性碳化稻壳在混凝土中的掺量上限为20%。【具体可参考《碳化稻壳制备工艺的相关介绍》的相关内容】
