I. Introduction
Lightweight concrete (LWC) allows for the production of reinforced concrete (RC) members that have a reduced own weight while maintaining a concrete strength that is of the same magnitude as normal weight concrete (NWC) [1]. Pantelides et al. [2] said “Reducing the own weight of a RC structure could considerably decrease the section dimensions of beams, slabs, columns, and foundations, which would enhance cost savings. An additional benefit of RC elements made with LWC is cutting lifting and transportation costs in the case of precast elements. LWC has been used for different purposes in the building industry”. For precast structures, Fig. 1 shows the construction of East Surrey Newspaper, Limited at Redhill. The structural frames with cladding panels were cast with LWC, using Solite aggregate. The concrete strength was 50 MPa with a density of 1900 kg/m3.
