Lightweight concrete mix. They can decrease dead load up to 20% – 80% depending on their types and components used within them with alteration in strength. Moreover, even they have low structural strength; their strength is still higher than the masonry elements like a brick. The air is an excellent insulating agent.

The flexural strength of light-weight aggregate concrete is lower than the normal weight concrete as in compressive strength (Hassanpour et al., 2012). The flexural strength of light-weight aggregate concrete can be increased by the inclusion of fibers (Hanif et al., 2016; Li et al., 2017; Libre et al., 2011).

Use a water-reducing admixture or a pumping aid. Replace a small amount of the coarse aggregate with sand. Use a slump of 4 to 6 inches and, if necessary, increase the cement content to maintain this high a slump. Use a well-graded natural sand with a fineness modulus of 2.2 to 2.7, or, if such sand is not available, increase the sand content.
