轻质粘土大砖,是一种新型的建筑材料.它具有良好的隔音、隔热性能,代替轻质混凝土用于建筑工程上,可以为国家节省大量的水泥,也可作为泡沫玻璃的代用品.由于它质量轻,有较高的强度,用于高层建筑不但可以减轻基础的荷重,同时还给施工创造了良好条件. 在总路线的光辉照耀下,我们和建筑工程部建筑科学研究院协作,已经在倒焰窑内烧成轻质粘土大砖.兹将我们的初步经验介绍如后. 一、原料土的处理和装料. 原料系使用不含砂的红胶土(即红粘土),膨胀度为2倍.这种土的化学成分为:二氧化矽53.50%,三氧化二铝22.83%,三氧化二铁6.54%,氧化钙1.48
The lightweight clay brick is a new type of building material. It has good sound insulation and heat insulation properties. It can replace the lightweight concrete used in construction projects and can save the country a lot of cement, and it can also be used as a substitute for foam glass. Due to its light weight and high strength, high-rise buildings can not only reduce the weight of the foundation, but also create favorable conditions for construction. Under the brilliant light of the general route, we cooperated with the Building Research Institute of the Ministry of Construction Engineering. The lightweight clay bricks have been burned in the down-draft kiln. We will introduce our preliminary experience as follows. I. Processing and loading of raw materials. Raw materials are made of red clay (ie, red clay) that does not contain sand. The degree is 2 times. The chemical composition of this soil is: 53.50% of ceria, 22.83% of aluminum oxide, 6.54% of iron oxide, calcium oxide 1.48
