Ugwu Abstract: This paper reports a research that investigated the application of industrial waste materials as mineral and chemical additives in the production of Self Compacting Concrete. The flow characteristics of the Self Compacting Concrete investigated were flowability, passing ability and segregation resistance in slump flow test, V-funnel test, L-box test and J-ring test. Pulverized fuel ash, carbide waste and quarry dust were used in concrete production. Compressive strength test was conducted on the hardened concrete after 28 days curing. Concrete mix ratio of 1:2:4 ( Cement : Sand : Gravel ) was used to produce concrete, using cement partially replaced with 5%, 10%, 15% and 20% pulverized fuel ash, carbide waste and quarry dust. Superplasticizer (Conplast SP 430) used in the mix was kept constant throughout the mixes at 1% of the total volume while water cement ratio of 0.45 was maintained in all mixes. Results of tests shows that the fresh Self Compacting Concrete produced with cement partially replaced with pulverized fuel ash, carbide waste, quarry dust and a combination of pulverized fuel ash and quarry dust satisfied requirements specified for Self Compacting Concrete. Flow ability, passing ability and resistance to segregation increase with pulverized fuel ash, carbide waste and quarry dust content. 28 day compressive strength of self-compacting concrete produced with only cement increased from 31.8 / 2 to 37.6 / 2 , 35.1 / 2 and 43.5 / 2 when cement was partially replaced with 20% pulverized fuel ash and a combination of 15% pulverized fuel ash and 15% quarry dust respectively. However, 28-day compressive strength decreased to 18.6 / 2 when cement was partially replaced with 20% carbide waste. Optimum 28 day compressive strength value was obtained when cement was replaced with 15% pulverized fuel ash plus 15% quarry dust. Regression analysis was computed on the data obtained from the slump flow test, J ring test, V funnel test and V funnel test using Microsoft Excel software to obtain regression equations for the filling ability, passing ability and segregation resistance.

Introduction Self-Compacting Concrete (SCC) differs from the normal concrete as it has the basic capacity to consolidate under its own weight. The increased awareness regarding environmental disturbances and its hazardous effects caused by blasting and crushing procedures of stone, it becomes a delicate and obvious issue for construction industry to develop an alternative remedy as material which can reduce the environmental hazards and enable high-performance strength to the concrete, which would make it durable and efficient for work. A growing trend is being established all over the world to use industrial by-products and domestic wastes as a useful raw material in construction, as it provides an eco-friendly edge to the construction process and especially for concrete[1,2].This evolving construction process paradigm is encapsulated in the triple R (i.e. reduce waste, re-use and recycle construction materials) that constitute global metrics and are precursor key performance indicators for infrastructure delivery vis-à-vis sustainable construction [3,4]. Self-Compacting Concrete is a rapidly developing research area within the construction industry. In the last four loving paradigm decades, concrete technologies have shown evolutional changes, apart from strength considerations, durability and economy have become important factors in the production of quality concrete. The concept of higher cement content translating to greater strength, and thus, durability has not been proven in true sense for structures when they are exposed to different climatic conditions. Therefore, to make concrete strong and
