Strength and workability are two limitations for wide application of lightweight concrete. In this thesis, multiple methods are used to increase the specific strength (the ratio between compressive strength and density), such as the use of low C3A cement, supplementary cementitious materials (SCMs)from industrial by-products, high-strength lightweight coarse and fine aggregates, pretreatment methods for aggregates, fibers and nano-materials. Different types of high workability, high specific strength lightweight concrete are investigated. Besides, durability, cost, CO2 emission andmicrostructure of lightweight concrete are evaluated. The target of high performance lightweight concrete with high workability and high specific strength is reached.
