Concrete Specs

	Aerolite lightweight concrete aggregates are manufactured in 7, 10, 14, and 20mm size ranges. However the most commonly used product is 14.0mm aggregate and the technical specs shown below are for this product size.
	Please note that we also produce lightweight concrete sand which if used in conjunction with our aggregate can produce final densities by another 10% to 15% based on the mix design used. This can lead to final concrete densities of 1,600 kgs/m3 at strengths up to 40 Mpa
	Light weight Aerolite concrete due to its vesicular nature has many other advantages: High thermal insulation, good noise attenuation, high fire rating.

PARTICLE DENSITY AND WATER ABSORPTION – 14mm Aggregate (Black) (as per AS 141.5)

AEROLITE LIGHTWEIGHT CONCRETE Basaltic, or heavyweight aggregate, normally used in dense weight concrete, has a specific gravity of 2.7–2.9 and a density of approximately 2610 kgs per cubic meter. Aerolite’s concrete aggregate is less than half this density and when used in place of heavier stone (representing approx 50% of total batch weight of concrete) reduces the finished weight of concrete by close to 25%. DESIGN DENSITIES OF AIR DRIED CONCRETE Heavyweight concrete: 2,650 Kgs/M³ AEROLITE Lightweight concrete: 1,850 Kgs/M³ If the sand used is replaced with Aerolite's Light weight Sand then it is possible to achieve a final concrete density of 1,600 Kgs/M³
	Un-compacted Bulk Density as per dry basis	0.77 Tonne/M3
	Apparent Particle Density	1.92 Tonne/M3
	Dry Particle Density	1.51 Tonne/M3
	Saturated Surface Dry Particle Density	1.72 Tonne/M3
	Water Absorption	12.3 %

Sieve Size (mm)	% Passing	*LIGHT BUT STRONG* With a ceiling strength of about 55 MPA at 28 days, lightweight concrete can be used for practically all construction applications. It is in common use for columns, beams, slabs and Precast walls in a wide variety of buildings. These range from two storey factories and office blocks to high rise commercial and residential projects.
