Environment-friendly recycled concrete brick
The invention discloses an environment-friendly recycled concrete brick, and relates to the technical field of building materials. The concrete brick is prepared from the following raw materials in parts by weight: 90 to 120 parts of cement, 60 to 80 parts of water, 30 to 40 parts of waste concrete blocks, 15 to 20 parts of calcium hydroxide, 5 to 15 parts of a reinforcing agent, 5 to 10 parts of a polycarboxylic acid type water reducer and 3 to 8 parts of a dispersing agent. The preparation method comprises the steps of (1) processing raw materials, specifically, transferring the raw materials into an outdoor concrete stirring tank, and fully and uniformly stirring to obtain a mortar mixture; (2) preparing a green brick, specifically, transferring the obtained mortar mixture into a brick making mold, and pressing to obtain the green brick; (3) performing drying and forming treatment, specifically, transferring the obtained brick blank into a drying box, drying, and removing the brick making mold to obtain a brick block; and (4) performing curing treatment, specifically, transferring the obtained brick into a curing chamber for curing. The prepared concrete brick is excellent in overall performance, and the recycling function is achieved.
本发明公开了一种环保型再生混凝土砖，涉及建筑材料技术领域。其中混凝土砖，以重量份计，包括以下原料：水泥：90份‑120份，水：60份‑80份，废弃混凝土块：30份‑40份，氢氧化钙：15份‑20份，增强剂：5份‑15份，聚羧酸系减水剂：5份‑10份，分散剂：3份‑8份；其制备方法如下：(1)原料处理：将上述原料转移至室外的混凝土搅拌罐中，充分搅拌均匀，得到砂浆混合物；(2)制作砖坯：将得到的砂浆混合物，转移到制砖模中，并进行压制，得到砖坯；(3)干燥成型处理：将得到的砖坯，转移到干燥箱中，并进行干燥，去除制砖模，得到砖块；(4)养护处理：将得到的砖块，转移到养护室内进行养护。制备的混凝土砖整体性能优异，实现循环再利用之功能。
