Stone dust as replacement for fine aggregate in cellular lightweight concrete (CLC): Volume weight and compressive strength

Abstract. A type of lightweight concrete called cellular (CLC) has a lower volume weight than ordinary and is made cement, sand, water, foaming agent. In this investigation, CLC was utilized as brick. The purpose study to ascertain how the compressive strength bricks would change if stone dust were used in place fine aggregate. Making with substitutions 0%, 50%, 100% aggregate experimental process study. light-weight that had been cured for 3, 7, 14, 28 days then measured. Because good binding capacity, results showed using it replacement mixture increased strength; highest value obtained at substitution days, which 24.62 kg/cm2. by 0.66 gr/cm3 when 50% dust, 2% 0.67 gr/cm3, 4% 0.68 dust. Due its range 0.6-1.8 brick can still be designated concrete.
