Lightweight concrete production with low Portland cement consumption

Feasible use of recycled CRT funnel glass as heavyweight fine aggregate in barite concrete

“…Recently, recycled aggregates derived from various sources with diverse characteristics have been shown to be able to be utilized in concrete. Some studies have been done with the incorporation of recycled rubber aggregates to make lightweight and hollow concrete blocks for better functional properties (Pelisser et al, 2012;Mohammed et al, 2012). According to Richardson et al (2012), the toughness of the concrete was enhanced as the amount of rubber increased, while Ho et al (2012) found that the rubberized concrete can contribute to resistance to cracking.…”

Utilization of alternative materials in lightweight composites

“…The compositions of the mixtures are presented in Table 5. The project (Pelisser et al, 2012) studied the use of recycled tire rubber for lightweight concrete with added metakaolin, with the dual purpose of reducing cement consumption while achieving satisfactory strength. Accordingly for the similar purposes, the amount of cement in mixtures 2, 3, 5 and 6 was partially or totally replaced by milled zeolite.…”

Formulation and characterization of structural lightweight concrete containing residues of porcelain tile polishing, tire rubber and limestone

“…Approximately 1.5 billion tires are manufactured yearly worldwide [18]. TRR is usually disposed on landfills, however, due to its difficult decomposition and considerable reduction of the useful life of landfills with this practice, disposal has proved to be environmentally impracticable [6].…”
