Geopolymer concrete based on coal cinder and preparation method thereof
The invention discloses geopolymer concrete based on coal cinder and a preparation method of the geopolymer concrete, and the geopolymer concrete comprises the following components in parts by mass: 400-450 parts of coal cinder; 180 to 230 parts of an alkali activator; 800 to 900 parts of fine aggregate; 800 to 900 parts of coarse aggregate; 1-20 parts of water; wherein the coal cinder needs to be pretreated, specifically, the coal cinder is ground through a ball mill till the particle size is 30-80 microns, then the coal cinder is placed in an electric furnace to be subjected to heat treatment, and the coal cinder is water-cooled to the room temperature. The geopolymer concrete based on coal cinder provided by the invention has good compression resistance, wear resistance and frost resistance, is high in early strength, and can be applied to projects needing to be put into use quickly.
本发明公开了一种基于煤渣的地聚物混凝土及其制备方法，按质量份数计，包括以下组分：煤渣400～450份；碱性激发剂180～230份；细骨料800～900份；粗骨料800～900份；水1～20份；其中，所述煤渣需进行预处理，具体为：将所述煤渣采用球磨机研磨至粒径为30～80μm，再置于电炉中进行热处理，水冷至室温。本发明提供的一种基于煤渣的地聚物混凝土具有良好的抗压性能、耐磨性能和抗冻性能，且早期强度高，可以应用于需要快速投入使用的工程。
