摘要
With the thickness of 1-2 mm made of FRP, a thin concrete scaleboard which can be used accompanying with concrete pouring was presented with the aim to improve the durability of concrete, in which the use of porous lightweight aggregate as roughing coating during FRP sheet producing was innovated to strengthen the bond performance between FRP sheet and concrete. Results indicated that lightweight aggregate with a particle size distribution from 3.15 to 4.75 mm showed nice bond performance, the average bond strength was 2.17 MPa. Bond strength was determined by mechanical interlocking and interfacial structure, and a bond equation was established.
