【Abstract】 In order to effectively solve the optimization problem of the preparation parameters of geopolymer premix, the quadratic regression equation was constructed by response surface test design and the mix ratio design was optimized. The mechanism of geo polymer premix was discussed by combining the macroscopic properties and microscopic morphology. The results show that when the maximum value of 28 d compressive strength and 28 d flexion strength is met, the optimal design ratio of polymer premix is as follows: slag content is 19.9%, water cement ratio is 0.36, solid activator content is 16%, the optimal design value of 28 d compressive strength is 22.1 MPa, 28 d flexion strength is 7.1 MPa, which meet the requirements. The error between the predicted value of construction condition and the experimental value is small, which indicates that the response surface method is used in the design and optimization of geopolymer experiment.更多还原
