Theoretical Analysis and Experimental Study of Strength Matching between Mortarless Grouted Concrete and Block Material

Abstract:

In order to solve the strength matching problem of grouted concrete and block in mortarless grouted masonry, the article adopts the ANSYS nonlinear simulation to establish different strength grade models. And the result shows that, when the strength matching relationship between the mortarless block and the concrete reaches f_c/f_b=1~2, the grouted concrete and block compressive strength are brought into full play without material waste. The result is close to f_cu/f_cb = 1.5~3.5 (gross area) from the literature^[1]. It is clear that, when the compressive strength of the two is close, their joint work can exert the best effects. It fits the experimental results and provides reference to the application of mortarless grouted block.
