The lightweight concrete (LWC) has been successfully employed, by the ancient Romans and its popularity has grown for its reduced density and higher thermal insulation capabilities. Compared to ordinary mix concrete (OMC), LWC can substantially lessen the dead load of high-rise structures. The density of LWC is comparatively low i.e. 300 to 1850 kg/m3, whereas conventional concrete has a unit weight of 2200kg/m3 to 2600kg/m3. Many pieces of research on adding disposable industrial wastes LWC focus on "semi-lightweight" or concrete built of lightweight materials which have provided both structural, financial, and environmental achievements. Synthetic lightweight aggregate derived from industries/environmental waste is not possible for reuse openly dumped and makes it environmental abuse. The lowering self-load of a structure made of lightweight concrete makes it easy the handling heavier pre-cast pieces. Present research involves of amalgamation of low specific weight “cinder” as coarse and fine aggregate replacements at various percentages and comparing the physical and mechanical characteristics of concrete made from it with orthodox concrete. The replacement was 10%, which will boost the flexural, tensile, and compressive strength if replaced as a fine Aggregate. The compressive strength, flexural splitting, and tensile strength of SF were raised by 20%. Will be cut back. Cinder added as coarse and fine aggregate in concrete, makes the LWC that enhances workability, foaminess, and up to 20% replacement as CA behaves as the ordinary normal concrete.
