High-strength anti-crack concrete and preparation method thereof
The invention discloses high-strength anti-crack concrete and a preparation method thereof, and relates to the field of concrete.The high-strength anti-crack concrete is prepared from, by weight, 50-70 parts of ardealite coarse aggregate; 1-5 parts of an ardealite gel material; 7.5 to 12 parts of cement; 3-5 parts of water; 25-40 parts of fine aggregate; 0.4-1 part of a water reducing agent; 0.5 to 1.5 parts of reinforcing fiber; the ardealite coarse aggregate is prepared by the following method: uniformly mixing ardealite, magnesium oxide, silicon oxide, clay and water, granulating, drying, screening to obtain pretreated particles, calcining the pretreated particles, carbonizing and curing to obtain the ardealite coarse aggregate. The phosphogypsum concrete has the effect of improving the compressive strength and crack resistance of the phosphogypsum concrete.
本申请公开了一种高强度抗裂混凝土及其制备方法，涉及混凝土领域，由包括以下重量份的组分制备得到：磷石膏粗骨料50‑70份；磷石膏凝胶材料1‑5份；水泥7.5‑12份；水3‑5份；细骨料25‑40；减水剂0.4‑1份；增强纤维0.5‑1.5份；所述磷石膏粗骨料采用如下方法制备得到：将磷石膏、氧化镁、氧化硅、黏土和水混匀、造粒、烘干、筛分得到预处理颗粒，对预处理颗粒进行煅烧、碳化养护得到磷石膏粗骨料。本申请具有提高磷石膏混凝土的抗压强度和抗裂能力的效果。
