Research on Preparation and Influencing Fctors of High Calcium High Sulfate Ash to autoclaved Aerated Concrete

矿物学报 2013年第S1期33卷 96-96页

作者： WAN Jun JIA Shaohui Guizhou Institute of Building Materials Scientific Research and Design Guizhou Engineering Technology and Research Center for the Comprehensive Utilization of Industrial Waste (Materials)

In this paper, a high calcium high sulfate ash as the main material, adding fly ash, lime, cement, gypsum and some modifiers to prepare autoclaved aerated concrete. The products complies with the technical requirements of GB/T11968-2006. This paper also studies the influence of the physical methods and water ratio on autoclaved aerated concrete by high calcium high sulfate ash aerated concrete. The best ratio of water and Grinding time were found in practice study.

关键词： high calcium high sulfate ash autoclaved aerated concrete ratio of water lime densification
