| Abstract: | Geopolymer was prepared at room temperature and atmospheric pressure,using activated coal-kaolinite,which was grinded,burnt and added with alkali activator.It was researched that mechanical properties of geopolymer mortar and concrete and binding performance of geopolymer paste and mortar.The results show that coal-kaolinite which is calcined at 850 ℃,and holds about 2 h,the made amorphous metakaolin which is activated by sodium silicate solution of modulus 1.2 and dosage about 9%,curing at autogenous condition,through these the new cementitinus material with better binding performance and early high strength is prepared.Analyzing the existing problems for popularization and application of the geopolymer at home and putting forward several suggestions according to personal researches. |
| Keywords: | geopolymer coal-kaolinite metakaolin alkali activator mechanical properties |
