Machine-made sand low-carbon self-compacting concrete with high stone powder content and preparation method of machine-made sand low-carbon self-compacting concrete
The invention discloses machine-made sand low-carbon self-compacting concrete with high stone powder content and a preparation method thereof, belongs to the technical field of building materials, and solves the problems that the self-compacting concrete in the prior art is large in binding material consumption, high in cost and large in CO2 emission. The high-stone-powder-content machine-made sand low-carbon self-compacting concrete is prepared from the following raw materials in parts by weight: 200 to 350 kg of cement, 50 to 100 kg of fly ash, 30 to 80 kg of mineral powder, 700 to 900 kg of high-stone-powder-content machine-made sand, 700 to 900 kg of gravel coarse aggregate, 10 to 20 kg of fiber, 20 to 35 kg of volume stabilizer, 5 to 11 kg of high-performance water reducing agent and 150 to 220 kg of water. Wherein the stone powder content in the high-stone-powder-content machine-made sand is 10-20wt%. The self-compacting concrete is prepared from the machine-made sand with high stone powder content, so that the use amount of a cementing material can be reduced, the production cost and the CO2 emission are reduced, and the obtained self-compacting concrete is good in various properties, good in volume stability and not easy to crack.
本发明公开了一种高石粉含量机制砂低碳自密实混凝土及制备方法，属于建筑材料技术领域，解决现有技术中自密实混凝土胶凝材料用量大、成本高和CO2排放量大的问题。本发明的高石粉含量机制砂低碳自密实混凝土由包括以下重量份的原料制成：水泥200～350kg，粉煤灰50～100kg，矿粉30～80kg，高石粉含量机制砂700～900kg，碎石粗集料700～900kg，纤维10～20kg，体积稳定剂20～35kg，高性能减水剂5～11kg，水150～220kg；其中高石粉含量机制砂中石粉含量为10～20wt％。本发明使用高石粉含量的机制砂制备自密实混凝土，能够减少胶凝材料的用量，降低生产成本和CO2排放量，所得自密实混凝土各项性能良好，体积稳定性好，不易开裂。
