Waste concrete hollow block recycled aggregate concrete and preparation process of concrete
The invention provides waste concrete hollow block recycled aggregate concrete and a preparation process of the concrete, the concrete is composed of the following raw materials in parts by weight: 250-320 parts of cement, 80-120 parts of fly ash, 990-1150 parts of coarse aggregate, 600-700 parts of fine aggregate and 8-13 parts of a water reducing agent, the coarse aggregate is natural gravel or/and recycled coarse aggregate, and the fine aggregate is natural sand or/and recycled fine aggregate. The preparation process comprises the following steps: preparing coarse aggregate and fine aggregate; preparing a mixture; and preparing the concrete. The product prepared by the invention meets the use requirements of low-strength grade common concrete, the waste concrete hollow blocks are effectively recycled, and the effects of protecting the environment and saving the cost are achieved.
本申请提供一种废混凝土空心砌块再生骨料混凝土及混凝土的制备工艺，所述混凝土由以下重量份原料组成：水泥250～320份、粉煤灰80～120份、粗骨料990～1150份、细骨料600～700份、减水剂8～13份，所述粗骨料为天然碎石或/和再生粗骨料，所述细骨料为天然砂或/和再生细骨料。所述制备工艺包括：粗骨料和细骨料制备；拌合物制备；混凝土制备。本申请制得的产物满足低强度等级普通混凝土的使用要求，且有效回收利用废混凝土空心砌块，达到了保护环境、节约成本的效果。
