Design method of oil shale residue concrete mix proportion
The invention provides a design method of an oil shale residue concrete mix proportion, which belongs to the technical field of concrete preparation and the field of solid waste building material resource utilization. The concrete is prepared from the oil shale residues in the form of coarse aggregate. The method comprises the following steps: (1) measuring the apparent density of various raw materials; (2) calculating a water-binder ratio, and determining unit water consumption, an initial sand rate and an oil shale residue volume substitution rate; (3) calculating the unit dosage of the cementing material and the dosage of the cement and the silicon powder, and determining the mixing amount of the water reducing agent and the steel fiber; (4) adjusting the sand ratio according to the volume ratio of the steel fibers; and (5) calculating the unit dosage of the sand, the stone, the oil shale slag and the pre-wetting water. The method is high in pertinence and good in operability, resource utilization of the oil shale waste building can be achieved, and obvious social and economic benefits are achieved.
本发明提供了一种油页岩渣混凝土配合比的设计方法，属于混凝土配制技术领域以及固体废弃物建筑材料资源化利用领域。本发明将油页岩渣以粗骨料的形式来制备混凝土，包括以下步骤：(1)测定各类原材料的表观密度；(2)计算水胶比，确定单位用水量和初始砂率、油页岩渣体积取代率；(3)计算胶凝材料单位用量以及水泥和硅粉的用量，确定减水剂和钢纤维的掺量；(4)根据钢纤维的体积率，调整砂率；(5)计算砂、石、油页岩渣、预湿用水的单位用量。本发明针对性强、可操作性好、能实现油页岩渣建筑资源化利用、具有明显的社会和经济效益。
