LIGHTWEIGHT CONCRETE
A lightweight structural concrete formulation comprises a wet mix of about 460 kg/m3 of cementitious material such as ordinary Portland cement of which about 50 percent has been replaced by ground granulated basic furnace slag (GGBFS) and 7 percent by silica fume (SF) in other words the mix introduces between about 178 and 228 kg/m3 therefore the combination is good to produce secondary reaction products when the cement hydrates which produces secondary calcium silicate hydrate (C-S-H) which makes the structure dense and thereby increases its mechanical durability characteristics of the concrete product. Possible ratios of GGBFS and SF are 30-70 percent and 5-10 percent, respectively. By making the structures dense increases the mechanical and durability characteristics of the concrete product. Other ratios have been made including GGBFS of 30-70 percent and silica fume 5-10 percent, respectively. It can be noted that the silica fume was added to the mixture as a supplementary cementitious material (SCM) not as an aggregate. It should also be noted that the particle sizes of GGBFS ranges between about 20-40 mm and that of silica fume is less than 20 mm.
