报告内容简介:
此次报告将介绍地聚物环保砖的研究进展。烧结粘土砖砌体是最古老的建筑材料之一,随着城市化发展,其需求量大幅度增加。砖的制造需要保持几天高温(1000− 1350ºC)。尽管在过去使用了各种助焊剂和燃料废物,但其温度仍然保持在1000℃以上,在降低温度方面并没有发挥显著作用。因此,转向相对环保的方法,如采用地聚物是当前所要,其仅需低温(最多200ºC)。为了开发环保的地聚合物砖,课题组采用粉煤灰(FA)和粘土作为基体开展了系列实验研究。对于粉煤灰基地聚物,通过压力和温度的耦合作用可使其强度最高。在满足各种规范成型压力(20 MPa)的环境养护条件下,最终获得了具有理想强度的试验砖。

Report content introduction:
This content is about the development of sustainable brick by geopolymerization. Masonry fired-clay brick is one of the oldest construction materials and its demand has been increased extensively due to urbanization. The manufacturing of bricks requires a high temperature (1000 - 1350 ºC), which is maintained for several days. Although various fluxing and fueling wastes have been utilized in past but it does not play any significant role in lowering temperature as it remains more than 1000 ºC. Therefore, shifting to a comparatively eco-friendlier method such as geopolymerization is the need of the hour as it requires low temperature (up to 200 ºC). Hence, the development of a geopolymer brick was the objective of this work, and detailed experimental investigations were carried out. Fly ash (FA) and clay were the main precursor used in this work. For the FA-based geopolymer the combination of pressure and temperature showed maximum strength. The pilot-scale brick with desired strength was obtained at ambient curing conditions at 20 MPa molding pressure satisfying various codes.
