粉煤灰是一种人工火山灰质材料。在混凝土中外掺适量符合国标GB 1596-79质量要求的磨细粉煤灰,能够改善砼性能,有利于泵送等施工新工艺的发展,同时也有利于“三废”处理和节约能源,减少环境污染,化害为利。城乡建设部、上海市科委、建委和建工局对此项应用技术十分重视,列为技术发展推广和攻关项目。由上海市建筑工程材料公司、建筑科研所、建筑施工研究所以及
Fly ash is an artificial pozzolanic material. Adding appropriate amount of ground fly ash in the concrete, which meets the quality requirements of the national standard GB 1596-79, can improve the performance of the concrete, and facilitate the development of new construction technologies such as pumping. It is also beneficial to the “three wastes” treatment and energy conservation and environmental reduction. Pollution, damage for profit. The Ministry of Urban-Rural Development, the Shanghai Municipal Science and Technology Commission, the Construction Commission, and the Construction and Industry Bureau paid great attention to this applied technology and listed it as a technology development promotion and research project.
