在伟大领袖毛主席的革命路线指引下,我省建筑部门广大职工发扬了“自力更生,艰苦奋斗,破除迷信,解放思想”的革命精神,对传统墙体材料——粘土砖进行了改革,试制和生产了承重粘土多孔砖。实践证明,用多孔砖代替实心砖,可以节省土地支援农业,是当前墙体改革的重要措施之一。生产多孔砖能节约25%的粘土,每生产一亿块空心砖,可以少挖农田25亩左右,我省每年约生产粘土砖三十亿块,如果推广80%多孔砖来代替实心砖可节约120万立米粘土,以取土深度3.5米计算可少占农田600亩,而且可以延长砖厂生产年限四分之一。在施工中用多孔砖代替实心砖砌墙能减轻墙体自重和相应的减少了运输量三分之一,节约砂浆水泥用最百分之十八,提高劳动生产率百分之十以上,每平米墙面造价降低20%左右,热工性能也较实心砖好。因此生产多孔砖代替实心砖,对于积极贯彻“鼓足干劲,力争上 Under the guidance of the revolutionary line of the great leader Chairman Mao, the majority of workers in the construction department of our province carried forward the revolutionary spirit of “self-reliance, hard work, breaking superstition, and emancipating the mind” and reformed the traditional wall material, the clay brick. Trial production and production of load-bearing clay perforated bricks. Practice has proved that using porous bricks instead of solid bricks can save land support for agriculture, and is one of the important measures for the reform of the current wall. The production of porous bricks can save 25% of clay, and for every 100 million hollow bricks produced, about 25 mu of farmland can be digging. About 3 billion clay bricks are produced each year in our province, and 120 percent of porous bricks can be used instead of solid bricks. Wan Limi clay, with a soil depth of 3.5 meters, can account for 600 acres of farmland, and it can extend the life of a brick factory by a quarter. The use of perforated bricks instead of solid brick walls in construction can reduce the wall weight and correspondingly reduce the transport volume by one-third, save 18% of mortar cement, and increase labor productivity by more than 10% per square meter. The cost of the wall is reduced by about 20%, and the thermal performance is also better than solid bricks. Therefore, the production of perforated bricks instead of solid bricks, for the active implementation of ”drums and dedication, and strive to
