Abstract:
A comprehensive experimental program was designed in order to investigate the mechanical and durability properties of high performance lightweight concrete. The concrete mixture was prepared in order to obtain a specific value of the compressive strength at 28 days of age (fCz75MPa). Testing was carried out on a large number of lightweight concrete specimens. The following properties were investigated: compressive, flexural and splitting-tensile strength, modulus of elasticity, fracture parameters, concrete-steel bond properties, drying shrinkage and durability properties. The test results show that high-performance lightweight concrete has considerable potential for the precast/prestressed industry.
