Ecological foam concrete and preparation method thereof
The invention discloses ecological foam concrete and a preparation method thereof. Comprising the following raw materials: 33.1%-44.0% of ordinary Portland cement, 0.6%-1.2% of XPS particles, 6.5%-8.8% of fly ash, 2.1%-3.0% of bone glue powder, 3.2%-8.7% of perlite particles, 1.7%-2.7% of nano titanium dioxide, 1.3%-3.0% of nano silicon dioxide, 0.6%-1.9% of alkali-resistant glass fibers, 1.3%-1.7% of a silane impregnant, 3.4%-4.0% of a rubber emulsion, 1.3%-1.7% of a silane coupling agent, 1.1%-1.5% of an accelerator, 0.5%-0.7% of an early strength agent and 0.3%-0.4% of a water reducing agent. The foaming agent comprises, by weight, 1.4%-3.7% of compound foaming agent diluent, 0.01%-0.03% of foam stabilizer and the balance water. According to the invention, by using the nano silicon dioxide photocatalyst and utilizing the high light transmission of XPS particles and the refractivity of first-grade perlite particles, the scattering and spreading range of sunlight ultraviolet rays in the internal pore wall structure of the foam concrete is improved, the illumination intensity is improved, and the driving efficiency of the photocatalyst for degrading pollutants such as nitrogen oxides and formaldehyde is enhanced; the degradation efficiency of the ecological concrete on environmental pollutants is integrally improved.
本发明公开了一种生态泡沫混凝土，按重量百分比，包括以下原料：普通硅酸盐水泥33.1％～44.0％、XPS颗粒0.6％～1.2％、粉煤灰6.5％～8.8％、骨胶粉2.1％～3.0％、珍珠岩颗粒3.2％～8.7％、纳米二氧化钛1.7％～2.7％、纳米二氧化硅1.3％～3.0％、耐碱玻璃纤维0.6％～1.9％、硅烷浸渍剂1.3％～1.7％、橡胶乳液3.4％～4.0％、硅烷偶联剂1.3％～1.7％、速凝剂1.1％～1.5％、早强剂0.5％～0.7％、减水剂0.3％～0.4％、复合型发泡剂稀释液1.4％～3.7％、稳泡剂0.01％～0.03％，余量为水。本发明以纳米二氧化硅光触媒，利用XPS颗粒的高透光性和一级珍珠岩颗粒的折光性，提高日光紫外线在泡沫混凝土内部孔壁结构的散射蔓延范围，提高光照强度，增强光触媒降解氮氧化物和甲醛等污染物的驱动效能，整体上提高了生态混凝土对环境污染物的降解效率。
