建筑工程部中南工程管理局于10月26日到11月3日在长沙召开了中南区空心粘土砖生产經驗交流会。会議交流了試驗、試制和生产粘土空心砖的經驗,着重討論了如何发展承重空心砖問題。会議认为,发展承重空心砖对节約农田、节省运輸力量和减輕建筑物重量,具有重要意义。生产和使用空心砖有許多优点:1.少用粘土,节約农田;2.降低煤耗,节約燃料;3.焙烧快,能提高窑的产量;4.孔壁烧透,表里一致,强度高,质量好;5.容重小,可节省劳动力,节約运輸装卸费用;6.隔热、防潮性能
The Central South Project Management Department of the Architectural Engineering Department held a seminar on the production of hollow clay bricks in the Central South District from October 26 to November 3. The meeting exchanged experiences on trials, trial production and production of clay hollow bricks, and focused on how to develop bearing hollow bricks. The meeting held that the development of bearing hollow bricks is of great significance for saving farmland, saving transportation power, and reducing the weight of buildings. There are many advantages to the production and use of hollow bricks: 1. Use less clay to save farmland; 2. Reduce coal consumption and save fuel; 3. Roasting fast, can increase the output of the kiln; 4. Hole wall burns through, consistent inside and outside, strength High, good quality; 5. Small weight, can save labor, save transport handling costs; 6. Insulation, moisture-proof performance
