Machine-made sand fair-faced concrete with self-cleaning function and preparation method of machine-made sand fair-faced concrete
The invention discloses machine-made sand fair-faced concrete with a self-cleaning function and a preparation method of the machine-made sand fair-faced concrete. Each cubic meter of the concrete comprises the following components by weight: 240 to 330kg of cement, 40 to 130kg of mineral powder, 40 to 70kg of fly ash, 710 to 770kg of machine-made sand, 1060 to 1120kg of broken stone, 12 to 18kg ofsilver-doped nanometer titanium dioxide, 3.6 to 5.1 kg of a water reducing agent and 140 to 160kg of water, wherein the silver-doped nanometer titanium dioxide is anatase type. The machine-made sandfair-faced concrete can be prepared by physically mixing the materials. The machine-made sand fair-faced concrete with the self-cleaning performance has good working performance and mechanical performance, the fair-faced effect is good after pouring forming, the excellent self-cleaning performance is achieved, and the machine-made sand fair-faced concrete with the self-cleaning performance has important practical application value.
本发明公开了一种具有自清洁功能的机制砂清水混凝土及其制备方法。每立方混凝土中，包括以下重量的组分：水泥240～330kg，矿粉40～130kg，粉煤灰40～70kg，机制砂710～770kg，碎石1060～1120kg，银掺杂纳米二氧化钛12～18kg，减水剂3.6～5.1kg，水140～160kg，其中所述银掺杂纳米二氧化钛为锐钛矿型。通过将各物料物理混合即可制备得到。本发明所述具有自清洁性能的机制砂清水混凝土具有良好的工作性能、力学性能，浇筑成型后清水饰面效果好，并兼具优异的自清洁性能，具有重要的实际应用价值。
