Process for preparing pavement concrete by using waste bricks and waste concrete as recycled coarse aggregates
The invention discloses a process for preparing pavement concrete by using waste bricks and waste concrete as recycled coarse aggregates. The process comprises the following steps of selecting cement, selecting the waste bricks and the waste concrete as the recycled coarse aggregates, selecting fine aggregates, and stirring and forming. The process has the advantages and positive effects that the compressive strength, the breaking strength and the dry shrinkage characteristic all meet the practical requirements of road surface layer concrete at the medium-light traffic load grade, and the effects of protecting the environment and saving the cost are achieved by recycling the construction waste.
本申请公开了一种废砖和废混凝土作为再生粗集料制备路面混凝土的工艺，包括如下步骤：选用水泥，选用废砖和废混凝土作为再生粗集料，选用细集料，搅拌成形；本申请具有的优点和积极效果是：抗压强度、抗折强度和干缩特性都满足中轻交通荷载等级的公路面层混凝土的实用要求，且回收利用建筑垃圾，达到了保护环境、节约成本的效果。
