Concrete with pumice waste residues as aggregates and preparation method of concrete
The invention discloses concrete with pumice waste residues as aggregates and a preparation method of the concrete. The concrete comprises the following components: 350-550 kg/m<3> of cement, 90-100 kg/m<3> of fly ash, 30-50 kg/m<3> of silica fume, 900-1000 kg/m<3> of the pumice waste residues, 170-250 kg/m<3> of water and 15-80 kg/m<3> of an additive, wherein the additive comprises the followingcomponents in percentage by mass: 4%-5% of a water reducing component, 0.8%-1.2% of a water retaining component, 0.8%-1.2% of a slump retaining component, 1.0%-1.5% of a thickening component and 92%-93% of a lubricating component. The surfaces of the pumice waste residues do not need to be treated at all, particle size screening of the pumice waste residues is not needed either, and direct application of the pumice waste residues can be achieved.
本申请公开的一种以浮石废渣为骨料的混凝土及其制备方法，包括如下组分：水泥350～550kg/m3，粉煤灰90～100kg/m3，硅灰30～50kg/m3，浮石废渣900～1000kg/m3，水170～250kg/m3，添加剂15～80kg/m3，其中，以质量百分比计，所述添加剂中减水组分占4％～5％，保水组分占0.8～1.2％，保坍组分占0.8～1.2％，增稠组分占1.0％～1.5％，润滑组分占92％～93％。本申请不需要对浮石废渣的表面进行任何处理，也不需要对浮石废渣进行粒度筛选，可以实现对浮石废渣的直接应用。
