Mix Proportion Optimization of Zeolite Ecological Concrete Based on Orthogonal Test
In order to explore the best ratio of zeolite ecological concrete,this paper designed 9 groups of zeolite ecological concrete with different mix ratios based on orthogonal test.The effects of target porosity,water-cement ratio and fly ash content and their three different levels on the compressive strength,actual porosity,permeability coefficient and pH value of zeolite ecological concrete were studied.The results show that the best mix ratio combination scheme of compressive strength is:target porosity 20％,water-cement ratio 0.35,fly ash content 20％;the best combination scheme of actual porosity,permeability coefficient and pH value is:target porosity 30％,water-ce-ment ratio 0.35,fly ash content 20％.To ensure the strength of zeolite ecological concrete,the combination with better mechanical proper-ties should be selected,which is the target porosity of 20％,water-cement ratio of 0.35,and fly ash content of 20％.It can be used in the projects,like the bottom of landfill sites,garbage bins,river bank concrete slope protection surfaces,park pavement.
