Concrete production process for preparing concrete from construction waste
The invention relates to a concrete production process for preparing concrete from construction waste. The concrete production process comprises the steps of S1, conducting crushing and impurity removal, specifically, a, crushing the construction waste; b, sorting the crushed construction waste, and removing impurities to obtain a concrete block and brick mixture; c, cleaning the concrete block and brick mixture to remove soil; S2, carrying out screening, specifically, screening the cleaned concrete block and brick mixture to obtain mixed aggregate with various particle sizes; S3, carrying out brick-concrete separation, specifically, respectively carrying out brick-concrete separation treatment on the mixed aggregates with various particle sizes to obtain brick aggregates with various particle sizes and concrete aggregates with various particle sizes; and S4, conducting concrete mixing, specifically, selecting brick aggregates or concrete aggregates with different particle sizes according to actual requirements, and mixing and stirring the aggregates with the concrete powder, water and the additive to obtain the recycled aggregate concrete. The method has the effect of improving the quality of the concrete prepared from the recycled aggregate.
本申请涉及一种利用建筑垃圾制备混凝土的混凝土生产工艺，其包括以下步骤：S1，破碎和除杂：a.对建筑垃圾进行破碎；b.对破碎后的建筑垃圾进行分拣，除去杂物后得到混凝土块和砖块混合物；c.对混凝土块和砖块混合物进行清洗，除去泥土；S2，筛分：对清洗后的混凝土块和砖块混合物进行筛分，得到多种粒径的混合骨料；S3，砖混分离：分别对多种粒径的混合骨料进行砖混分离处理，得到多种粒径的砖骨料和多种粒径的混凝土骨料；S4，拌合混凝土：根据实际需求选用不同粒径的砖骨料或混凝土骨料，将骨料与混凝土粉料、水、添加剂混合并搅拌，得到再生骨料混凝土。本申请具有提高再生骨料制备的混凝土的质量的效果。
