Experimental Research on Recycled Concrete Road Base of Geopolymer Technology
This paper presents an experimental study on the physical and mechanical properties of porous ecological concrete by performing ten groups of tests.It shows that the coarse aggregate size,porosity,water-cement ratio,and admixture have significant effect on the strength of the porous ecological concrete.The pH value of the porous ecological concrete is effectively reduced to a certain range that is suitable for the growth of the vegetation.An optimized aggregate size from 15 mm to 25 mm,a water-cement ratio of 0.35–0.40 and the inclusion of the special admixture is introduced,so that the porous ecological concrete can have enough space for the vegetation growth and eligible strength for the structural application.The porous ecological concrete is also proved to be suitable for the growth of the vegetation.
