Roller compacted concrete with low adiabatic temperature rise, good durability and large mixing amount of activated phosphorus slag powder
The invention discloses roller compacted concrete with low adiabatic temperature rise, good durability and a large mixing amount of activated phosphorus slag powder. The roller compacted concrete comprises the following components in parts by mass: 80 parts of cement; 20 to 120 parts of fly ash; 20 to 100 parts of activated phosphorus slag powder; 100 parts of water; 740 parts of machine-made sand; 1430 parts of broken stone; 2 parts of a water reducing agent; 0.15 part of an air entraining agent; and 12 parts of magnesium oxide. The activated phosphorus slag powder is prepared by uniformly mixing an activating agent and phosphorus slag powder in a ratio of 0.5: 1 and grinding for 1 hour by a ball mill, wherein the activating agent comprises the following components: carbide slag, aluminumsulfate slag, red mud, gypsum, anhydrous calcium sulphoaluminate minerals and cellulose ether. Along with the doping of the phosphorus slag powder, the compactness of the concrete is improved, the durability of the concrete is improved, the mixing amount of the phosphorus slag is large, meanwhile, the actual engineering production and construction requirements are met, the durability of the roller compacted concrete is good, and the 28d adiabatic temperature rise value of the phosphorus slag powder is much lower than that of single-doped fly ash.
本发明公开了一种绝热温升低耐久性好大掺量活化磷渣粉碾压混凝土，包括质量百分比计的水泥：80份；粉煤灰：20‑120份；活化磷渣粉：20‑100份；水：100份；机制砂：740份；碎石：1430份；减水剂：2份；引气剂：0.15份；氧化镁：12份。所述活化磷渣粉是由活化剂与磷渣粉按0.5:10质量比混合均匀后经球磨机研磨1h而成，其中：活化剂成分包括：电石渣、硫酸铝渣、赤泥、石膏、无水硫铝酸钙矿物、纤维素醚，随着磷渣粉的掺入有利于改善混凝土的密实性，提高了混凝土的耐久性，磷渣掺量大同时满足工程实际生产、施工需求、耐久性好的碾压混凝土，28d绝热温升值磷渣粉的要比单掺粉煤灰低的多。
