Density of sintered fly ash aggregate decreases with the ratio of replacement . Density is defined as mass per unit volume that means how much amount of mixture concrete, is per cubic meter volume.

Construction aggregate, or simply "aggregate", is a broad category of coarse to medium grained particulate material used in construction, including sand, gravel, crushed stone, slag, recycled concrete and geosynthetic aggregates. Aggregates are the most mined materials in the world.
For lightweight concrete with 14 mm Lytag coarse aggregate and conventional fine aggregate (sand), SCI design examples will assume a wet density of kN/m³ (of which is reinforcement allowance) and a dry density of kN/m³.
To achieve the required concrete density to absorb the radiation a combination of highdensity aggregates steel shot (fine aggregate) and hematite ironore (coarse aggregate) was used. The use of high density aggregates increased the cost for 40 Mpa concrete from approximately to R7 per cubic metre of concrete in 1996.
It is widely used in the construction industry to increase the volume of concrete, thus it is a cost saving material and you should know everything about the fine aggregate size, its density and grading zone to find the best material.
The 28 days compressive strength of these concrete mixes is in structural range. The decrease in compressive strength is mainly due to the weak bond between the cement paste and the type of aggregate used in the concrete. Density of the aggregate also influences the strength of concrete (Aslam et al. 2016a, b; Okpala 1990). Tensile strength of SLC
