Summary:

The deterioration in concrete structures exposed to harsh environments has become a matter of global concern. The requirement for high durability in concrete structures cannot be easily achieved using ordinary portland cement. Therefore, new materials and composites are being investigated and improved cements are produced to enhance the concrete durability. The present state of the art in concrete research has demonstrated the benefits of by-product mineral admixtures s as partial cement replacements. The by-product mineral admixtures (industrial waste) such as fly ash, slag and silica fume are used as partial cement replacement to enhance the performance of concrete. In addition, the use of by-product materials conserves energy and has environmental benefits as a result of the reduced use of cement (the production of which is associated with high carbon dioxide emission). This research was aimed at investigating the performance of concrete utilizing locally available industrial waste. The industrial waste was incorporated in concrete as partial cement replacement to study the effect of replacement level on the fresh and hardened properties of concrete at various ages. Results of chemical analysis of industrial waste, fresh properties and strength of concrete prepared with this material are reported.
