| 摘 要： | 在其它条件恒定时,研究了碳酸钠掺量对水泥土强度的影响.对比水泥土7d和28 d的强度发现,水泥土的强度总体上随碳酸钠掺量的增加先增大后减小;随龄期增长,水泥土强度峰值前移.分析原因主要为:碳酸钠促进水化作用和抑制硅酸凝胶转化为沉淀的双重功能,碳酸钠抑制了对水泥土后期强度增长有重要作用的火山灰效应等.

| Abstract: | In the other conditions constant,the relationship between the sodium carbonate mixing ratio and strength of cemented soil was studied.Through comparing cemented soil's strengths of 7 days and 28 days,it has been presented that with the increasing of sodium carbonate mixing ratio,the cemented soil's strengths first increased and then decreased and that the peak strength of cemented soil move forward with age increase.The main reasons are that sodium carbonate promotes the hydration and inhibits conversion of... |
