吉林省延边地区,盛产天然轻骨料浮石,自1979年以来,该地区利用浮石混凝土空心砌块建造房屋已达20万平方米,有单层房屋亦有多层房屋,主要用于外墙,墙厚为24厘米。根据测定,砌体容重为923公斤/米~3,每平方米墙面自重只有两砖红砖墙的1/4;墙体热阻为0.63米~2·度/瓦,很接近两砖红砖墙的热阻值(0.64);砌体强度亦比材料标号相同的砖石砌体高,可以建造五层以下的房屋;每平米墙面造价比红砖墙低4.7元;生产砌块的建厂投资少;施工进度块。因此,这种砌块房屋已深受
The Yanbian area of Jilin Province is rich in natural light aggregate pumice. Since 1979, the area has used pumice stone and concrete hollow blocks to build houses of 200,000 square meters. There are single-storey houses and multi-storey houses, mainly for external walls. The wall is 24 cm thick. According to the measurement, the bulk density of masonry is 923 kg/m~3, and the weight of the wall surface per square meter is only 1/4 of the two brick red brick walls; the thermal resistance of the wall is 0.63 m~2·degree/W, which is very close to two brick reds. The thermal resistance of the brick wall (0.64); masonry strength is also higher than that of masonry bricks with the same material number, can build houses under five stories; the cost per square meter of the wall is 4.7 yuan lower than that of the red brick wall; Less investment in construction; construction progress block. Therefore, this type of block house has been deeply
