Ultrahigh remote pumping machine-made sand high-strength concrete
The invention discloses ultrahigh remote pumping machine-made sand high-strength concrete. The ultrahigh remote pumping machine-made sand high-strength concrete comprises cement, a mineral admixture, machine-made sand, gravel, a functional additive, a water reducing agent and water, and the functional additive is formed by mixing inorganic phosphate, organic phosphonate and a defoaming agent according to the mass ratio of (30-60): (30-60): (5-10). The water reducing agent is a multi-branched strong-polarity water reducing agent prepared from a multi-branched strong-polarity monomer, an unsaturated functional monomer K, an unsaturated adsorption monomer L and alkenyl-terminated polyether M through free radical polymerization. According to the ultrahigh remote pumping machine-made sand high-strength concrete, limitation on the content of stone powder in machine-made sand is reduced, and the concrete is good in workability, low in viscosity and easy to pump.
本发明公开了一种超高远程泵送机制砂高强混凝土。本发明所述超高远程泵送机制砂高强混凝土包括水泥、矿物掺合料、机制砂、碎石、功能助剂、减水剂及水，所述功能助剂由无机磷酸盐、有机膦酸盐、消泡剂按质量比30～60：30～60：5～10混合而成，所述减水剂为由多支化强极性单体、不饱和功能单体K、不饱和吸附单体L和端烯基聚醚M通过自由基聚合制备获得的多支化强极性减水剂。本发明所述超高远程泵送机制砂高强混凝土中不仅降低了对机制砂中石粉含量的限制，而且混凝土的和易性好、粘度低、易泵送。
