Abstract:
Concrete is the main material used in construction, composed of water, fine aggregate, coarse aggregate, and cement. The aggregates, sourced from nature, are depleting rapidly due to excessive use for development, creating a future shortage. To address this, it's essential to find alternatives. Demolition waste, a byproduct of construction and renovation Demolish concrete is huge problem we are facing now a days waste accumulates in large quantities, hampers the environment of disposal sites.

The current study addresses the growing environmental issue of waste from blast high furnaces, particularly iron and steel plants in Libya. It investigates the fresh and mechanical properties of Self-Compacting Concrete (SCC) by substituting conventional aggregate with slag aggregate. The fresh properties of SCC were assessed using slump flow diameter, T50 flow time, J-ring, and L-box tests. Its mechanical properties were also evaluated, including compressive strength, flexural strength, splitting tensile strength, and Ultrasonic Pulse Velocity (UPV). Various replacement ratios were tested, 30

Abstract:
The properties of concrete containing coarse recycled aggregates were investigated. Laboratory trials were conducted to investigate the possibility of using recycled aggregates from the demolition wastes available locally as the replacement of natural coarse aggregates in concrete. A series of tests were carried out to determine the density, compressive strength, split tensile strength, flexural strength and modulus of elasticity of concrete with and without recycled aggregates. The water cement ratio was kept constant for all the mixes. The coarse aggregate in concrete was replaced with 0%, 2

This study assessed the usefulness of the replacement of coarse aggregate partially with electronic waste (e-waste) plastic in lightweight concrete since developing countries have been challenged with management of e-waste as well as high cost of coarse aggregates for concrete production. Coarse aggregates were replaced with e-waste plastic in concrete at 5%, 10%, 15%, and 20% for a concrete class of C20. The particle size distribution of the e-waste plastic aggregates was determined as well as the slump, compressive strength, water absorption and bulk density of the concrete. Generally, the s

To address these issues, supplementary cementitious materials (SCMs) like silica fume and fly ash, along with polypropylene (PP) fibres, were incorporated in this study.
