High-strength light-transmitting concrete and preparation method thereof
The invention relates to high-strength light-transmitting concrete and a preparation method thereof. The light-transmitting concrete comprises a concrete matrix and light-transmitting fibers arrangedin the concrete matrix, and the raw material formula of the concrete matrix comprises the following components by weight: 550-900 parts of Portland cement; 140-300 parts of silica fume; 80-250 parts of mineral powder; 3-20 parts of a polycarboxylate superplasticizer; 850-1450 parts of fine sand; 80-180 parts of steel fiber; 5-40 parts of nano silicon dioxide and/or nano calcium carbonate; and 130-280 parts of water. Specific nanoparticles are added into the concrete matrix of the light-transmitting concrete, the formula of the concrete matrix is optimized, and the light-transmitting fibers areused in cooperation, so that the light-transmitting concrete has ultrahigh strength, high durability and good light-transmitting performance. The light-transmitting concrete can be used for emergencyescape platform plates, concrete inner and outer walls, decorative plates and the like, and is wide in application range.
本发明涉及一种高强度透光混凝土及其制备方法，该透光混凝土包括混凝土基体及设置在混凝土基体内的透光纤维，按重量份计，混凝土基体的原料配方包括以下组分：硅酸盐水泥550~900份；硅灰140~300份；矿粉80~250份；聚羧酸减水剂3~20份；细砂850~1450份；钢纤维80~180份；纳米二氧化硅和/或纳米碳酸钙5~40份和水130~280份。本发明通过在透光混凝土的混凝土基体中添加特定纳米颗粒，并优化混凝土基体的配方及配合透光纤维的使用，使得透光混凝土具有超高强度、高耐久性能且具有较好的透光性能。采用本发明的透光混凝土可用于应急逃生平台板、混凝土内外墙及装饰板等，应用范围广。
