Experimental study and recommendation on concrete cover thinkness of GFRP

摘要

Concrete cover thin kness of GFRP to ensure the safety, applicability and durability of the structure is of great significance. Based on studies to 30 the drawing specimens of concrete, get bond strength of same GFRP diameter, same concrete strength, different concrete cover thinkness. Through the analysis of test data, it is concluded the relationship of the bond strength and the concrete cover thinkness. And basis on the relationship, it is determine the suggestive values on concrete cover thinkness of GFRP. Experimental data and suggestion can provide reference and theoretical basis for the GFRP engineering application and the establishment of the relevant specification.
