Solid waste concrete and preparation method thereof
The invention relates to the technical field of concrete, and particularly discloses solid waste concrete and a preparation method thereof. The mixture of the solid waste concrete is prepared from the following components in parts by weight: 300 to 320 parts of cement, 80 to 100 parts of solid waste mineral admixture, 1150 to 1250 parts of coarse aggregate, 580 to 620 parts of iron-carrying machine-made sand, 200 to 240 parts of modified mineral wool fiber, 156 to 160 parts of water and 3.8 to 4.2 parts of polycarboxylate superplasticizer. The modified mineral wool fiber is used, and ferric sulfate is loaded in the clay brick machine-made sand, so that the iron-loaded machine-made sand is obtained, the water reducing effect of the polycarboxylic acid water reducing agent can be fully exerted, the water absorption rate of the machine-made sand is reduced, the slurry of a concrete mixture can have good fluidity, and the performance of the concrete mixture is improved. The construction of a concrete mixture is facilitated.
本申请涉及混凝土技术领域，具体公开了一种固废物混凝土及其制备方法。固废物混凝土的拌和物包括如下重量份的组分：水泥300‑320份，固废矿物掺合料80‑100份，粗骨料1150‑1250份，载铁机制砂580‑620份，改性矿棉纤维200‑240份，水156‑160份，聚羧酸减水剂3.8‑4.2份。本申请使用了改性矿棉纤维，并在粘土砖机制砂中负载了硫酸铁，得到了载铁机制砂，使聚羧酸减水剂的减水作用能够更加充分地发挥，而且降低了机制砂的吸水率，能够令混凝土拌和物的浆体具有较好的流动性，有利于混凝土拌和物的施工。
