Concrete mix proportion design method adopting granite waste stone powder as aggregate
The invention discloses a concrete mix proportion design method adopting granite waste stone powder as aggregate. The concrete mix proportion design method comprises the following steps: selecting materials, obtaining the mix proportion of gel, obtaining the cement use amount of concrete, and obtaining the use amount of granite waste stone powder aggregate. The method comprises the following steps: selecting the cement dosage, gel ratio expected value and aggregate amount of one cubic meter of concrete, determining the apparent density of one cubic meter of concrete according to an assumed volume-weight method, then calculating the dosage of various materials of one cubic meter of concrete, and selecting two different cement dosages for trial mixing of concrete according to the assumed volume-weight method; the actual gel ratio is inversely calculated according to the final actual water consumption; calculating the use amount of each material in one cubic meter of concrete; detecting the slump of fresh concrete, checking the gel ratio, measuring the apparent density of the concrete, molding a concrete test piece, and carrying out analytical statistics; the concrete mix proportion design method adopting the granite waste stone powder as the aggregate is simple in process and very high in success rate.
本发明公开了一种采用花岗岩废石粉作为骨料的混凝土配合比设计方法，所述混凝土配合比设计方法包括如下步骤：选料，获取凝胶的配合比、获取混凝土的水泥用量，获取花岗岩废石粉骨料用量；选定一立方米混凝土的水泥用量、凝胶比预期值以及骨料量，按假定容重法确定一立方米混凝土的表观密度，然后计算一立方米混凝土各种材料用量，同时按照假定容重法再选择两种不同水泥用量试拌混凝土，以最后实际用水量反算实际凝胶比；计算的一立方米混凝土各种材料用量；检测新拌混凝土的坍落度，核定凝胶比，测定混凝土的表观密度，装模成型混凝土试件，分析统计；该种采用花岗岩废石粉作为骨料的混凝土配合比设计方法，过程简单，成功率很高。
