砂基透水混凝土路面砖胶结料试验研究
Experimental Study on Cementing Material of Sand-based Permeable Concrete Pavement Brick
摘要
Abstract
The influences of self-developed admixture with different contents, water-cement ratio, aggregate gradation and ash-aggregate ratio on the strength and water permeability of sand-based permeable concrete pavement bricks were studied, and test the water retention, frost resistance, wear resistance, resistance to sulfate attack and dry-wet cycles performance of the specimen through the indoor test.Firstly, compare the self-developed admixture Ⅰ with three kinds of admixtures of the same type through the mortar test and choose the best.The results show that the admixture Ⅰ ( 28 d ) has compressive strength of 59.2 MPa and bending strength of 9.3 MPa, which is better than the same type of admixture; the optimal amount of admixture Ⅰ with sand-based permeable concrete pavement is 5% of cement mass.The strength is 35.6 MPa, the water permeability coefficient is 3.5×10 -2cm/s, and it has good water retention, frost resistance, wear resistance and resistance to sulfate attack and dry-wet cycles.关键词
