Description
Summary:The influence of each factor on the reaction of geopolymers material was investigated by using the orthogonal experimental design method, which got the optimal condition of reaction. Based on this results the performances of geopolymers were investigated. The results are as follows： （1） The effect of each factor on the compressive strength of geopolymers was different; （2） For paste the optimal condition of reaction is that the modulus and the concentration of sodium silicate solution are 1.2 and 40%, the calcined temperature and calcined time of kaolin are 800 ℃ and 2 h, and the liquid-solid ratio is 1.25; （3） When the pH value of solution is higher than l, the compressive strength of Geopolymers will not decrease as that in the water; （4） As the calcined temperature of samples were lower than 700 ℃ the heat-resistant of geopolymers was good;（5） Geopolymers is unlikely to react with the active aggregate.
