为了满足农村建房的迫切需要和改变我国地方性建材生产的落后状况,我们利用南方地区资源丰富的红土作基材,加入适量的水泥、砂和外加剂,研制成功一种免烧的农用水泥红土砖(不需蒸压或蒸养)。一年来我们制作了3600多块试件、标准砖及空心砖,进行了材料性能、配合比设计、成型工艺参数、物理力学性能、耐久性及微观结构等方面的研究工作,各项主要技术指标均达到相
In order to meet the urgent need of building houses in rural areas and to change the backwardness of local building materials production in China, we have used the rich red earth as the base material in the southern region and added appropriate amounts of cement, sand and additives to develop a non-burning agricultural cement. Laterite bricks (without autoclaving or steaming). Over the past year, we have produced more than 3,600 pieces of specimens, standard bricks and hollow bricks, and conducted research work on material properties, mix ratio design, molding process parameters, physical and mechanical properties, durability and microstructure, and all major technical indicators Achieve phase
