Highlights
The construction industry searches the alternatives to satisfy the increasing need for cement necessary for concrete production
The values increased with the increase in the proportional ratio of WGP content and with highest value at 20% cement replacement which further confirmed the use of WGP as possessing pozzolanic property
The Compressive strengths declined at above 10% replacement level of cement at 28 days curing which indicates that 10% and 15% replacement levels meet the requirement of BS EN 206-1: 2000 for class C25/30 and C20/25 respectively for heavy weight concreting and LC25/28 and LC20/22 respectively for light weight concreting
Summary
The construction industry searches the alternatives to satisfy the increasing need for cement necessary for concrete production. The use of supplementary cementitious materials (SCMs) to offset a portion of the cement in concrete is a promising method for reducing the environmental impact from the industry. These materials are used to create blended cements which can improve concrete durability, early and long term strength, workability and economy (Detwiler, Bhatty & Bhattacharja, 1996). While Nigeria is committed to actively reduce greenhouse emissions (CO2 emissions), which is the trending issue globally, the construction industries have been searching ways to reduce it production if the large amount of waste materials generated were used to replace natural materials in the construction industry. These would result to three benefits: conserving natural resources, disposing of waste materials (which are often unsightly) and freeing up valuable land for other uses (Blewett & Woodward, 2000)
