High-strength recycled concrete and production process thereof
The invention relates to the field of building materials, and particularly discloses high-strength recycled concrete and a production process thereof. The high-strength recycled concrete is prepared from, by weight, 45-50 parts of cement, 15-20 parts of water, 10-15 parts of coal ash, 90-120 parts of compound recycled aggregate and 8-12 parts of a water reducing agent, wherein the compound recycled aggregate is prepared by mixing and crushing pebbles and recycled aggregate according to a mass ratio of (2-3): (10-13). The pebbles and the recycled aggregate are mixed and crushed to prepare the recycled aggregate, and sharp edges and corners existing on the surface of the recycled aggregate are ground, so that the surface structure of the recycled concrete material is improved, and a good compact structure is formed after concrete is filled with the recycled material; and therefore, the mechanical property and the mechanical strength of the recycled concrete material are improved.
本申请涉及建筑材料领域，具体公开了一种高强度再生混凝土及其生产工艺，高强度再生混凝土包括下列重量份物质：45～50份水泥、15～20份水、10～15份粉煤灰、90～120份复配再生骨料、8～12份减水剂；所述复配再生骨料为按质量比2～3:10～13，将卵石与再生骨料混合破碎制备而成。本申请通过将卵石与再生骨料混合破碎来制备再生骨料，将再生骨料的表面存在的尖锐棱角进行研磨，改善再生混凝土材料的表面结构，使再生料填充至混凝土内部后形成良好的密实结构，从而提高了再生混凝土材料的力学性能和机械强度。
