High-strength and high-ductility geopolymer concrete and preparation method thereof
The invention discloses high-strength and high-ductility geopolymer concrete, which is prepared from the following raw materials in parts by weight: 25 to 30 parts of steel slag, 7 to 9 parts of phosphorus slag powder, 1 to 3 parts of calcined sodium bentonite, 1 to 3 parts of silica fume, 33 to 40 parts of quartz sand, 11 to 18 parts of compound alkali activator, 6 to 8 parts of water, 0.02 to 0.04 part of dispersing agent, 0.03 to 0.05 part of defoaming agent and 1 to 3 parts of modified fine steel fiber. 0.03 to 0.05 part of modified multi-walled carbon nanotubes and 0.5 to 0.7 part of modified PVA (Polyvinyl Alcohol) fibers. The geopolymer concrete disclosed by the invention is relatively high in setting speed, and relatively high in ductility, compressive strength, acid resistance, low-temperature performance and the like can be considered; the preparation method is simple, mild in preparation condition and suitable for popularization and application.
本发明公开了一种高强高延性地聚合物混凝土，各原料及其所占重量份数包括：钢渣25‑30份，磷渣粉7‑9份，煅烧钠基膨润土1‑3份，硅灰1‑3份，石英砂33‑40份，复合碱激发剂11‑18份，水6‑8份，分散剂0.02‑0.04份，消泡剂0.03‑0.05份，改性精细钢纤维1‑3份，改性多壁碳纳米管0.03‑0.05份，改性PVA纤维0.5‑0.7份。本发明所述地聚合物混凝土的凝结速度较快，并可兼顾较高的延性、抗压强度、耐酸性和低温性能等；且涉及的制备方法较简单、制备条件温和，适合推广应用。
