锂渣、粉煤灰高性能混凝土抗压强度试验研究

Experimental study on the compressive strength of high performance concrete added with lithium slag and fly ash

通过试验研究了水胶比、锂渣掺量及粉煤灰掺量对锂渣、粉煤灰高性能混凝土不同龄期抗压强度的影响。试验结果表明:混凝土各个龄期的抗压强度均随着各因素水平的增加呈现先增大后减小的规律。其中:水胶比对混凝土抗压强度的影响最为显著,锂渣掺量对混凝土早期抗压强度影响较为显著,而粉煤灰掺量则对混凝土后期抗压强度有着显著影响。

It studies the contribution of water to binder ratio,lithium slag dosage and fly ash dosage to the compressive strength at different ages of high performance concrete added with lithium slag and fly ash.The experiment demonstrates that the compressive strength at every age of concrete will increase before reduce along with the increase level of each factor.The water to binder ratio has the most important influence among the three factors.The lithium slag dosage has a great impact on the compressive strength at early ages of high performance concrete while the fly ash dosage produce a big effect on the compressive strength in the later period.
