Recycled aggregate concrete and preparation method thereof
The invention provides recycled aggregate concrete. The recycled aggregate concrete comprises the following components in parts by mass: 80-180 parts of recycled coarse aggregate, 20-50 parts of natural fine aggregate, 20-30 parts of steel slag, 30-50 parts of cement, 30-60 parts of fly ash, 10-20 parts of silica fume, 0.3-1.0 part of calcium formate, 0.3-0.6 part of a water reducing agent and 40-80 parts of water, wherein the recycled coarse aggregate comprises the following components in parts by mass: 240-320 parts of engineering spoil micro powder, 20-40 parts of an alkaline activator, 100-120 parts of cement, 120-180 parts of mineral ultrafine powder, 2-4 parts of water glass and 80-100 parts of water. The recycled aggregate concrete is high in compressive strength and good in durability.
本发明提供了一种再生骨料混凝土，其各组分及质量配比为：再生粗骨料80～180份，天然细骨料20～50份，钢渣20～30份，水泥30～50份，粉煤灰30～60份，微硅粉10～20份，甲酸钙0.3～1.0份，减水剂0.3～0.6份，水40～80份；其中再生粗骨料各组分及质量配比为：工程弃土微粉240～320份，碱性激发剂20～40份，水泥100～120份，矿物质超细粉120～180份，水玻璃2～4份，水80～100份。该再生骨料混凝土的抗压强度高、耐久性能好。
