Hybrid fiber reinforced coral sand concrete and preparation method thereof
The invention discloses a hybrid fiber reinforced coral sand concrete preparation method, which comprises: weighing raw materials, adding a polycarboxylic acid water reducer into artificial seawater, stirring, mixing Portland cement, silica fume and fly ash, stirring to obtain a cementing material, sequentially adding 1/2 of the mixture, coral sand fine aggregate and the remaining mixture into the cementing material, uniformly stirring, and uniformly mixing to obtain the hybrid fiber reinforced coral sand concrete. And then adding carbon fibers and stainless steel fibers containing a dispersing agent to obtain concrete containing hybrid fibers, or adding the coral sand fine aggregate, 2/3 of the mixture, the carbon fibers containing the dispersing agent, the residual mixture and the stainless steel fibers into a cementing material in sequence to obtain concrete containing hybrid fibers, and adding the concrete containing hybrid fibers into a mold for curing to obtain the hybrid fiber reinforced coral sand concrete. The concrete prepared by the invention has the advantages of excellent early strength, high static compressive strength, high dynamic tensile strength and the like.
本发明公开了一种混杂纤维增强珊瑚砂混凝土的制备方法，包括称取原料，将聚羧酸减水剂加入人工海水中搅拌，将硅酸盐水泥、硅灰、粉煤灰混合搅拌得胶凝材料，将胶凝材料中先后加1/2混合物、珊瑚砂细骨料和剩余混合物，然后加含分散剂的碳纤维和不锈钢纤维，得含混杂纤维的混凝土，或者将胶凝材料中先后加珊瑚砂细骨料、2/3混合物、含分散剂的碳纤维、剩余混合物和不锈钢纤维，得含混杂纤维的混凝土，加入模具中养护，得到混杂纤维增强珊瑚砂混凝土。本发明制备的混凝土兼具优异的早强性、高静态抗压强度和高动态抗拉强度等优点。
