Alkali-activated fiber reinforced pervious concrete and manufacturing method thereof
The invention relates to alkali-activated fiber reinforced pervious concrete, which is prepared from the following raw materials in parts by weight: 350 to 407 parts of granulated blast furnace slag, 1543 parts of coarse aggregate, 51 to 125 parts of water glass, 0 to 2 parts of sisal fiber and 47 to 86 parts of water. The water glass is prepared from liquid sodium silicate and a sodium hydroxide solution, and the modulus of the water glass is 1.0-1.6. The granulated blast-furnace slag is granulated blast-furnace slag micro-powder for cement and concrete, the particle size is 300 meshes, and the granulated blast-furnace slag comprises the following chemical components: 34.11% of silicon dioxide and 15.31% of aluminum oxide. And the coarse aggregate is stones with the particle size range of 5-10mm. The strength of the pervious concrete is higher than that of existing pervious concrete, and the pervious concrete is higher in setting and hardening speed and early strength. And the alkali-activated slag material can be recycled, is low-carbon and energy-saving, and is a potential substitute material for cement-series materials.
本发明涉及一种碱激发纤维增强的透水混凝土，包括以下重量份计的原料：粒化高炉矿渣350‑407份、粗骨料1543份、水玻璃51‑125份、剑麻纤维0‑2份和水47‑86份。水玻璃为由液体硅酸钠和氢氧化钠溶液配制成模数为1.0‑1.6的水玻璃。粒化高炉矿渣为用于水泥和混凝土的粒化高炉矿渣微粉，粒径尺寸为300目，粒化高炉矿渣的化学成分含有二氧化硅含量34.11%和氧化铝含量15.31%。粗骨料为粒径范围为5‑10mm的石头。通过本发明得到的透水混凝土强度比现有透水混凝土的凝结硬化快，早期强度高。且碱激发矿渣材料能废物利用、低碳节能，是水泥系材料的潜在替代材料。
