| 摘 要： | 本文利用基于密实体积理论的轻骨料混凝土配合比设计方法,通过试验确定其中关键参数—紧密因数CF的最佳取值范围,以强度、干表观密度和坍落度、扩展度等作为评价依据。运用正交设计方法,优化确定试验配合比。通过采取掺加矿物掺合料和具备增粘作用的高效减水剂,保证混凝土拌合物具有较好的工作性能,满足轻骨料混凝土的免振捣施工的要求,配制出了强度等级为LC25~LC50的免振捣轻骨料混凝土。

| Abstract: | In this paper,based on the theory of dense volume of lightweight aggregate concrete mix design method,determined by experiments in which the key parameters-the best close range factor CF in order to strength,dry apparent density and slump,extended degree reflects the work of performance indicators as a basis for evaluation.Using orthogonal design method,optimizing the mixture ratio to determine testing.By taking admixture with mineral admixtures and super plasticizer testifying role to ensure that concrete ... |
