Lead smelting slag-based green pavement concrete and preparation method thereof
The invention discloses lead smelting slag-based green pavement concrete and a preparation method thereof, and belongs to the field of solid waste treatment and green pavement concrete. Comprising the following raw materials in parts by mass: 52.5 to 122.5 parts of lead smelting slag, 122.5 parts of cement clinker, 84 to 154 parts of mineral powder, 21 parts of desulfurized gypsum, 627 to 784 parts of river sand, 1176 to 1333 parts of gravel and 126 to 154 parts of water. The slump of the concrete is 38 mm, and the actual construction requirements are met. The 3d flexural-tensile strength is 4.21 Mpa, the 28d flexural-tensile strength is 7.15 Mpa, and the flexural-tensile strength far exceeds the design requirements of the flexural-tensile strength of medium and light load pavements; the 3d compressive strength is 41.5 Mpa, the 28d compressive strength is 58.4 Mpa, and the C50 concrete strength requirement is met; the abrasion resistance is 3.840 kg/m < 3 >, and the requirement for the abrasion loss of third-grade and fourth-grade highway surface layer concrete is met.
本发明公开了一种铅冶炼渣基绿色路面混凝土及其制备方法,属于固废处理、绿色路面混凝土领域。包括以下质量份数的原料:铅冶炼渣52.5‑122.5份,水泥熟料122.5份,矿粉84‑154份,脱硫石膏21份,河砂627‑784份,碎石1176‑1333份,水126‑154份。该混凝土塌落度为38mm,符合实际施工要求。3d弯拉强度为4.21Mpa,28d为7.15Mpa,远超中、轻载荷路面弯拉强度设计要求;3d抗压强度为41.5Mpa,28d为58.4Mpa,达到C50混凝土强度要求;耐磨量为3.840kg/m3,符合三、四级公路面层混凝土磨损量要求。
