Experimental Study on Compressive and Shear Strength of Recycled Concrete Blocks at Different Ages
In order to explore the relationship between compressive strength,shear strength and curing age of recycled concrete hollow block,the paper conducted experiments on the differences in mechanical properties of concrete hollow block under different curing ages.The test re-sults show that the shear strength and compressive strength of recycled concrete hollow blocks are significantly improved with increasing curing age.The compressive strength and shear strength increased most obviously when the curing age was extended from 7 days to 14 days.It is sug-gested to improve the forming effect of high masonry strength according to the actual demand in engineering practice.
