Abstract：To further investigate the influence of calcium phosphate chemical dealkalization method on the planting performance of porous concrete,porous concrete specimens were soaked in 1%,2%,and 3%calcium phosphate and potassium dihydrogen phos-phate solutions,after soaking,high fescue,Manila grass and alfalfa were selected for planting tests.The results shows that the dealka-lization effect of 2%calcium phosphate solution is the best,with a stable pH value of 7.3.Compared with the untreated porous con-crete,the plant height of high fescue,Manila grass,and alfalfa increased by 17.9%,14.3%,and 3.9%respectively.The calcium phos-phate chemical dealkalization method has a significant influence on the pH value of the porous concrete pore solution and the plant-ing performance.Reasonably choosing the dealkalization method can optimize the performance of planting concrete.
