Early-strength concrete for emergency repair engineering and preparation method of early-strength concrete
The invention discloses early strength concrete for a first-aid repair project. The building material is prepared from the following components in parts by weight: 12 to 4 parts of hydrophilic modified hyperbranched sulfonate surfactant SHBP-12, 0.5 to 0.8 part of N-(2-hydroxyethyl) guanidine, 0.8 to 1.2 parts of sulfonated ethylene propylene diene monomer, 15 to 25 parts of cement, 0.5 to 1.5 parts of graphene coated nano aluminum powder, 8 to 10 parts of coal cinder, 8 to 12 parts of water, 30 to 35 parts of fine river sand and 40 to 45 parts of gravel. The invention further discloses a preparation method of the early strength concrete for the emergency repair engineering. The early strength concrete for the emergency repair project is good in comprehensive performance and performance stability, remarkable in early strength effect, good in anti-seepage and anti-cracking performance, excellent in durability and corrosion resistance and safe and environment-friendly to use.
本发明公开了一种抢修工程用早强混凝土，其特征在于，是由如下按重量份计的各组分组成：亲水改性超支化磺酸盐表面活性剂SHBP‑12‑4份、N‑(2‑羟基乙基)胍0.5‑0.8份、磺化三元乙丙橡胶0.8‑1.2份、水泥15‑25份、石墨烯包覆纳米铝粉0.5‑1.5份、煤渣8‑10份、水8‑12份、细河砂30‑35份、碎石40‑45份。本发明还公开了一种所述抢修工程用早强混凝土的制备方法。本发明公开的抢修工程用早强混凝土综合性能和性能稳定性好，早强效果显著，抗渗抗裂性能佳，耐久性和抗腐蚀性优异，使用安全环保。
