Abstract: This paper examined how the strength properties of plain concrete performance can be improved by the introduction of hooked-ends steel fibres by volume fraction and fly ash as replacement for cement into concrete batch with the objective of bridging the inherent brittle nature and dramatic disadvantages such as poor deformability and weak crack resistance of plain concrete in practical usage. Compressive and flexural strengths of concrete cubes and prisms produced with fly ash as partial replacement for cement at 0, 10, 20, 30 and 40%, with incorporation of steel fibres at 0%, 0.50%, 0.75% and 1.00% by volume fraction of concrete were determined. Seventy five (75) concrete cubes of size 150x150x150 mm were cast. Compressive strength of concrete cube specimens was evaluated 7, 14, 21, 28 and 56 days. Compressive strength results indicated that 10% fly ash replacement outperformed all other percentage replacements including the control mix replacement of 0% fly ash. The strength developm

Abstract: This work is aimed to evaluate the effect of recycled and virgin high density polyethylene (HDPE) and low density polyethylene (LDPE) waste granules on selfconsolidating concrete mixture including Municipal Solid Waste Incineration (MSWI) fly ash. Within the scope of experimental, five SCC mixtures were designed. The effect of plastic particles as coarse aggregate substitution has been evaluated by the mechanical and physical tests on fresh and hardened concrete. At the end of the study, the drying shrinkage behavior and compressive strength of SCC mixtures were improved by the addition of plastic waste granules.
