本文研究了石灰石粉作为混凝土掺合料对混凝土工作性能、力学性能的影响和改善.。研究表明:石灰石粉作为掺合料能较有效的改变混凝土的工作性能,并且可以使混凝土坍落度损失变小,早期强度得到提高。粉煤灰和石灰石粉复合掺加时,两者共同使用可以有效节约水泥。
This paper studies the influence and improvement of limestone powder as concrete admixture on the performance and mechanical properties of concrete. The results show that limestone powder as admixture can effectively change the performance of concrete, and can reduce the slump loss of concrete and improve the early strength. Fly ash and limestone powder mixed together, both can effectively save the cement.
