近年来随着墙体改革工作的发展,小型空心砌块在我国已逐渐为建筑业所接受,受到各方面的重视而得到发展。广州市1979年生产了小型混凝土空心砌块7万立方米,竣工的小型砌块建筑达18万平方米。通过实践,也暴露了一些问题,例如,建筑工人反映小型砌块太重劳动强度大,希望能从现在的每块重17～18公斤降为10～14公 In recent years, with the development of the wall reform work, small hollow blocks have gradually been accepted by the construction industry in China, and have received attention from all sides and have been developed. In 1979, Guangzhou produced 70,000 cubic meters of small concrete hollow blocks and completed small block buildings of 180,000 square meters. Through practice, some problems have also been exposed. For example, construction workers have complained that small blocks are too heavy and labor-intensive. They hope to reduce their weight from 17 to 18 kilograms to 10 to 14 kilograms.
