Superfine sea sand concrete and preparation method thereof
The invention provides superfine sea sand concrete and a preparation method thereof. The superfine sea sand concrete is prepared from 500-555 parts of coarse aggregate, 35-60 parts of medium aggregate, 330-380 parts of superfine sea sand, 18-38 parts of waste tire particles, 2-4 parts of fibers, 115-135 parts of cement, 35-40 parts of fly ash, 15-20 parts of silica fume, 65-73 parts of seawater, 1.9-3.5 parts of a water reducing agent and 0.6-1.3 parts of a collapse retaining agent. Wherein the fineness modulus of the superfine sea sand is 0.35-0.50, and the particle size of the superfine sea sand is less than 1mm; the fiber is basalt fiber, the length is 6-10 mm, and the diameter is 15-25 [mu] m; the particle size of the waste tire particles is 2-5mm; the water reducing agent is a polycarboxylic acid water reducing agent; the fibers cover the surfaces of the waste tire particles. The environment problem caused by transportation of natural river sand is reduced through superfine sea sand, meanwhile, waste tire particles and fibers are bonded through a granulation process and added into concrete, and the service life is prolonged.
本申请提供了一种超细海砂混凝土及其制备方法，通过粗骨料500～555份、中骨料35～60份、超细海砂330～380份、废旧轮胎颗粒18～38份、纤维2～4份、水泥115～135份、粉煤灰35～40份、硅灰15～20份、海水65～73份、减水剂1.9～3.5份、保塌剂0.6～1.3份；其中，超细海砂的细度模数0.35～0.50，粒径小于1mm；纤维为玄武岩纤维，长度6～10mm，直径15～25μm；废旧轮胎颗粒的粒径2～5mm；减水剂为聚羧酸减水剂；纤维覆盖在废旧轮胎颗粒的表面。通过超细海砂减少天然河砂运输带来的环境问题，同时将废旧轮胎颗粒和纤维通过造粒工艺粘合，加入到混凝土中，提高使用寿命。
