高掺量粉煤灰绿色建筑材料的开发应用

Research on the Exploratory Development of Green Building Materials with High Content of Fly Ash

高掺量粉煤灰 (掺量≥ 5 0 %)绿色建筑制品的研究开发是目前粉煤灰综合利用的重点开发研究课题。高掺量粉煤灰砖固化技术是高效高值利用粉煤灰的一项新技术 ,具有显著的经济效益、社会效益和环保效益。本课题组发明的粉煤灰固化技术其粉煤灰掺量达到 85 %以上 ,砖强度达到 10MPa以上。本文对粉煤灰砖的抗冻性能及其强度的影响因素进行了讨论。

At present, the exploratory development of green building goods with high content of fly ash is an important research topic in which fly ash is used comprehensively. High content of fly ash means that the quantity of blended fly ash is not lower than 50 percent of the weight of bricks. The technique of solidifying fly ash invented by us will make the quantity of fly ash amount to 85 percent of the weight of bricks whose compressive strength exceeds 10 Mpa. In this paper, the factors affecting frost resistance and compressive strength of the fly ash brick are discussed. The technique is a new means, which utilizes fly ash effectively and exhibits notable economic, social and environmental results.
