碳化稻壳有以外掺或内掺形式掺入混凝土,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

掺入具有分散作用的减水剂,使碳化稻壳增强作用得到充分发挥,这是由于稻壳灰掺入混凝土后


掺入具有分散作用的减水剂,使碳化稻壳增强作用得到充分发挥,这是由于稻壳灰掺入混凝土后,高活性的sio2能较快地与水泥水化生成的氢氧化钙起强烈的火山灰反应形成低钙水化硅酸钙凝胶,起到增加强度,改善骨料水泥石界面结构和填充毛细孔的作用,使混凝土密实性增加,强度大为提高,劈裂抗拉强度、粘结强度、轴心抗压强度、静压弹模、抗氯离子渗透、防锈等性能都得到明显提高和改善。试验结果还表明,使用“双掺”技术效果更佳,因此由专家研究得出的结论是:掺碳化稻壳能制造高强、密实、耐钢锈混凝土,可用来建造大型现代建筑物和高速公路。【具体可参考《碳化稻壳对能源及三农存在哪些好处?》的相关内容】
