Key Parameter

Taking free shrinkage as the key parameter in evaluating cracking of concrete, the cracking properties of self-compacting concrete with strength grade of C35 and C50 were investigated based on ring and slab restraint tests. Meanwhile, the ultimate tensile strain of self-compacting concrete was studied by using flexural test. Experimental results show that the shrinkage of self-compacting concrete is lower than that of normal concrete. Self-compacting concrete cracks later than normal concrete with the same strength grade. Although the ultimate flexural tensile strains of self-compacting concrete in 7 d and 28 d are a little bit lower than that of the normal concrete, it can still be concluded from the research that the cracking property of self-compacting concrete can be greatly improved by using proper mix proportion.

Glass Fibre Reinforced

In this experimental study, the tensile behaviour of bolted joints of pultruded glass fibre reinforced polyester sandwich composites was investigated. The transverse specimens cut normal to the pultrusion direction failed by net-tension whereas the longitudinal specimens cut parallel to the pultrusion direction failed by a combination of bearing and shear-out modes. The joint strength was dependent on the specimen geometry in the case of transverse specimens whereas it was not in the case of longitudinal specimens.
