Mechanical Properties of Red Mud-Slag Based Geopolymer Solidified Loess after Freeze-Thaw Cycle
摘要
Abstract
In this paper,the maximum dry density and optimum content of geopolymer solidified loess under different red mud content,water glass modulus and water glass content were obtained by compaction test.Based on the optimum moisture content results,the test blocks were made and the freeze-thaw cycle test of geopolymer solidified loess was carried out.The mass loss and unconfined compressive strength of solidified loess test block were tested,and the influence of geopolymer composition on frost resistance of solidified loess test block was analyzed.The results show that the maximum dry density of geopolymer solidified loess test block is smaller than that of plain loess.Adding an appropriate amount of geopolymer can effectively improve the frost resistance of loess,and the unconfined compressive strength of solidified loess is greater than that of plain loess,up to 0.7 MPa.With the increase of red mud content,the unconfined compressive strength of solidified loess test block decreases.With the increase of freeze-thaw cycles,the unconfined compressive strength of solidified loess test block decreases first and then increases,and finally tends to be stable.关键词
