Early-strength composite concrete admixture and preparation method thereof
The invention discloses an early-strength composite concrete admixture and a preparation method thereof. The early-strength composite concrete admixture comprises hydrated calcium silicate seed crystals, a mineral admixture and an expanding agent. The preparation method comprises the following steps: weighing the hydrated calcium silicate seed crystals, the mineral admixture and the expanding agent, and carrying out mixing. The early-strength composite concrete admixture provided by the invention can obviously improve the 16-h compressive strength of mortar, and later strength is not reduced.
本发明公开了一种混凝土早强复合掺合料及制备方法，混凝土早强复合掺合料包括：水化硅酸钙晶种、矿物外加剂和膨胀剂；制备方法包括：称取水化硅酸钙晶种、矿物外加剂和膨胀剂，混合而成。本发明的混凝土早强复合掺合料可明显提高砂浆16h抗压强度，且后期强度无倒缩。
