Road cement
The invention belongs to the technical field of building materials, and discloses road cement. The road cement is prepared from the following raw materials in parts by weight: 30-60 parts of a road cement clinker, 2-7 parts of phosphogypsum, 10-20 parts of slag, 10-20 parts of steel slag, 10-20 parts of a wear-resistant toughening material, 2-5 parts of allophane powder, 2-5 parts of calcium sulphoaluminate, 0.003-0.01 parts of a grinding aid and 0.003-0.01 parts of N-hydroxymethyl acrylamide. According to the invention, the mineral composition of the clinker is optimized, so that the clinkerhas higher strength, the mixing amount of the admixture in the cement is increased, the matching property of the road cement clinker and the admixture is good, the existing industrial by-products arefully utilized, and certain economic benefits and environmental protection benefits are achieved.
本发明属于建筑材料技术领域，公开了一种道路水泥，由以下重量份数的原料制备而成：道路水泥熟料30‑60份、磷石膏2‑7份、矿渣10‑20份、钢渣10‑20份、耐磨增韧材料10‑20份、水铝英石粉2‑5份、硫铝酸钙2‑5份、助磨剂0.003‑0.01份、N‑羟甲基丙烯酰胺0.003‑0.01份。本发明优化了熟料矿物组成，使熟料具有较高的强度，增加了水泥中混合材的掺入量，道路水泥熟料与混合材匹配性好，充分利用现有工业副产物，具有一定的经济效益和环保效益。
