| 摘 要： | 按照不同钢渣掺比制作了混凝土样块, 测定了不同钢渣掺比和不同养护条件下混凝土样块的抗压强度以及浸出pH 值, 研究了不同钢渣掺比下混凝土样块的抗压强度与水化反应的关系和机理. 实验结果表明: 20% 钢渣掺比为最佳掺比, 而超过30% 掺比之后的混凝土抗压强度逐渐下降; 混凝土样块在去离子水中的浸出pH 值随钢渣的掺比和混凝土样块碳化时间的不同而变化, 主要原因是钢渣含有一定量的低铁铝相.

| Abstract: | Compressive strength tests of concrete specimens were made using different components of steel slag. The pH values of concrete specimens in water was determined after certain curing. Relationship between compressive strength and hydration reaction in various components of steel slag was analyzed. Experimental results show that the optimal steel slag-mixing ratio is 20%. The compressive strength of concrete decreases as the steel slag-mixing ratio is over 30%. The pH values of concrete differs significantly with the steel slag mixed and carbonization time of concrete specimens mainly because steel slag contains a reasonable amount of the low-Fe-Al phase. |
