Tough formwork member concrete for fabricated composite system and preparation method of tough formwork member concrete
The invention discloses tough formwork member concrete for an assembly type composite system and a preparation method of the tough formwork member concrete. The concrete is prepared from a cementing material, sand, steel fibers, organic fibers, a water reducing agent, a defoaming agent and water. The cementing material is prepared from the following components in percentage by mass: 70 to 90 percent of ordinary Portland cement and 10 to 30 percent of sulphoaluminate cement; the water reducing agent accounts for 5-6% of the total mass of the cementing material, and the defoaming agent accounts for 0.1-0.2% of the total mass of the cementing material; the volume mixing amounts of the steel fibers and the organic fibers are 0.3%-0.7% and 0.1%-0.2% of the total amount of the concrete respectively; by mass, the ratio of the cementing material to the sand is (1: 1.4)-(1: 1.6), and the water-binder ratio is 0.28-0.32. The problems of workability and early strength of tough formwork concrete are solved, the formwork turnover efficiency is improved, meanwhile, the problem of balance of rigidity and toughness is solved, and the requirement for the rigidity of a building formwork and the requirement for the toughness of the formwork are met.
本发明公开了一种用于装配式复合体系的韧性模壳构件混凝土及其制备方法，混凝土包括胶凝材料、砂、钢纤维、有机纤维、减水剂、消泡剂和水；以质量百分数计，所述胶凝材料由占比70％～90％的普通硅酸盐水泥和占比10％～30％的硫铝酸盐水泥组成；所述减水剂与消泡剂分别为胶凝材料总质量的5％～6％与0.1％～0.2％；所述钢纤维与有机纤维的体积掺量分别为混凝土总量的0.3％～0.7％与0.1％～0.2％；以质量计，所述胶凝材料与砂的比例为1:1.4～1:1.6，水胶比为0.28～0.32。本发明解决了韧性模壳混凝土工作性与早期强度的问题，加快了模板周转效率，同时解决了刚度与韧性相平衡的问题，既满足建筑模板刚度要求，又满足模板韧性要求。
