我公司东城处在某工地,用拆除旧房后留下的砖渣,破碎后充当混凝土骨料,浇灌墙体,历经两年,效果良好。现将情况介绍如下。一、材料及试配情况墙体材料由水泥、砖渣(城砖、青条砖、红机砖、碎混凝土块等)、粉煤灰、砂子、水、外加剂按比例组成。在现浇墙体前,作了试配,试配的情况见表一。最后选定水泥用量最少,强度满足设计要求的配合比:水泥:烟灰:砂子:碎砖为1:1:5:7.5。并 My company, Dongcheng, is located at a construction site and uses brick slag left after the demolition of the old house. After crushing, it acts as a concrete aggregate and pours the wall. After two years, the effect is good. The situation is as follows. 1. Materials and Matching Conditions Wall materials consist of cement, brick slag (city bricks, green bricks, red bricks, broken concrete blocks, etc.), fly ash, sand, water, and admixtures. In front of the cast-in-place wall, test fittings were made and the test mix was shown in Table 1. Finally, choose the least amount of cement, the strength to meet the design requirements: cement: soot: sand: broken brick is 1:1:5:7.5. and
