以煤炭燃烧后的残渣——炉渣灰——作为平房灰打顶的骨料,在我国绝大部分地区已经沿用日久。但对于远离厂矿的农村和山区,炉渣常属于一种造价高昂的短缺材料。这里介绍一种以碎粘土砖头作灰打顶的方法——碎砖轻质混凝土的屋顶及其操作方法。炉渣灰的容量是1000公斤/米~3,碎粘土砖的容量是1200公斤/米~3。设想一幢60～70米~3的屋顶需要5米~3的轻骨料,则用碎砖比用炉渣灰作骨料,共多1000公斤的自重,每平方米多15公斤左右的自重。这个数字对整个屋顶承重结构是微不足道的。碎砖轻质混凝
After the coal burning residue - slag ash - as the ash-capped aggregate of cottage, in most parts of our country has been in use for a long time. However, for rural areas and mountainous regions far from factories and mines, slag is often a kind of shortage of materials with high cost. Here we introduce a method of using crushed clay bricks for ash-crushing - crushed brick lightweight concrete roofs and their methods of operation. The capacity of slag ash is 1000 kg/m~3, and the capacity of crushed clay bricks is 1200 kg/m~3. Imagine that a 60-70 m~3 roof needs 5 to 3 light weight aggregates, and uses crushed bricks as the aggregate for slag ash, a total of 1,000 kilograms of deadweight, and about 15 kilograms more weight per square meter. This number is insignificant for the entire roof bearing structure. Broken brick lightweight coagulation
