High-strength and strong-flow-state bare concrete and bare concrete road edge stone prepared from high-strength and strong-flow-state bare concrete
The invention discloses high-strength and strong-flow-state bare concrete and a bare concrete road edge stone prepared from the same, and belongs to the technical field of building materials. The high-strength and strong-flow-state bare concrete disclosed by the invention is prepared from the following components according to the content of concrete per cubic meter: 260 to 290 kg of cement, 870 to 900 kg of broken stone, 710 to 750 kg of sand, 8 to 10 kg of an additive, 80 to 100 kg of silica fume, 250 to 300 kg of slag powder and 160 to 200 kg of water. The slump expansion degree of the fair-faced concrete provided by the invention is 650-750 mm and is close to that of self-compacting concrete; compared with the prior art, the cement consumption is lower, the slag powder consumption is higher, the early strength of the concrete is high, the production period is shorter, the color of the concrete is coordinated by the slag powder and the silica fume and is very close to that of stone, and a concrete appearance anti-seepage and anti-fouling treatment technology is applied, so that the prepared product adapts to the use environment of the road edge stone, and the service life of the road edge stone is prolonged. And the cleaning of components is facilitated, and the later maintenance cost is reduced.
本发明公开了一种高强大流态清水混凝土及其制备的清水混凝土路沿石，属于建筑材料技术领域。本发明的高强大流态清水混凝土，以单位立方混凝土含量计的组份为：水泥260kg～290kg，碎石870kg～900kg，砂710kg～750kg，外加剂8kg～10kg，硅灰80kg～100kg，矿渣粉250kg～300kg，水160kg～200kg。本发明提供的清水混凝土坍落扩展度在650～750mm，接近自密实混凝土；并且本发明相对于现有技术水泥用量更低，矿渣粉用量更高，混凝土早期强度高，生产周期更短，颜色经过矿渣粉和硅灰的协调，十分接近石材，并且运用了混凝土外观防渗防污处理技术，使制备的产品适应路沿石的使用环境，并且，利于构件的清洁，还降低了后期维护成本。
