Quick-drying early-strength fine aggregate concrete and preparation method thereof
According to the quick-drying early-strength fine aggregate concrete and the preparation method thereof, sulphoaluminate cement and ordinary Portland cement are compounded, the sulphoaluminate cement and ordinary Portland cement interact with each other, the setting time of the concrete is shortened, the early strength of the concrete is improved, and the compressive strength of the prepared concrete after 24-hour normal-temperature curing is larger than 20 MPa; meanwhile, the later strength of the concrete is also improved by compounding the two components, and the 28-day compressive strength of the prepared concrete is greater than 40MPa, so that the application range of the concrete is enlarged.
本发明公开了一种快干早强细石混凝土及其制备方法，采用硫铝酸盐水泥与普通硅酸盐水泥进行复配，二者相互作用，缩短了混凝土凝结时间，提高了混凝土的早期强度，制得的混凝土经过24小时的常温养护抗压强度大于20MPa；同时，二者复配也提升了混凝土的后期强度，制得的混凝土28天抗压强度大于40MPa，进而增大了混凝土的应用范围。
