This paper reports a part of an ongoing experimental laboratory investigation being carried out to evaluate the mechanical properties of concrete made by Fine Material Associated with Coarse Aggregate Production (FMACAP) is considered a solid waste in Libya. However, based on previous researchers, Fine materials production with coarse aggregate is considered a pozzolanic materials waste that causes environmental pollution. In order to limit this pollution And it can act as additive and improve the properties of concrete, the fine wastes are being used as an alternative to imported materials such as fly ash and silica fume which adding to concrete for producing concrete with high strength, low cost and good durability of concrete. Therefore, the superplasticizer which is one type of chemical admixtures will be added to blended cement concrete in order to improve the workability of concrete. But strength development of Fine Material Associated with Coarse Aggregate Production (FMACAP) concrete, there will be some effects when chemical admixtures are added. In this study, the Concrete specimens were tested and compared with plain concrete specimens. However, mixes concrete with fineness namely 75 mic and consists of 5%, 7.5%, 10%, 12.5% and 15% as additive materials. However, mixes contain superplasticizer with percentage 1.6%. To investigate the fresh concrete properties, the slump test and flow table test were conducted. While for hardened concrete properties, compressive strength test was conducted. Strength development of Fine Material Associated with Coarse Aggregate Production (FMACAP) concrete was studied during all tests for hardened concrete properties. Conclusively, superplasticizer added into Fine Material Associated with Coarse Aggregate Production (FMACAP) concrete will improve workability and strength of Fine Material Associated with Coarse Aggregate Production (FMACAP) concrete and such concrete can be effectively used in structural applications.
