Abstract

 This study aims to use marble powder as a marginal by-product material (which disposal of it may cause environmental problems) in production of self-compacting concrete (SCC) to reduce the cost of cubic meter (direct cost). 11 mixtures of self-compacting concrete were designed in experimental program. Five variables were studied in this research: amount of marble powder (15% and 30% (, amount of superplasticizer (2% and 3 %(, type of mineral Additives (silica fume and fly ash (, amount of mineral additives (Silica fume 5% and 10 %) - (Fly ash 25% and 35 %( and replacement silica fume and fly ash with marble powder. Fresh concrete tests were performed are: slump flow, slump flow at T50cm , V-funnel  , V-funnel at T5min, L-box , Fill box and GTM sieve 5mm stability test. Hardened concrete tests were performed are: compressive strength test and bending strength test. High performance SCC can be produced with range of compressive strength about (440-580) kg/cm² with marble powder only. The cheapest mixtures which have the minimum requirements to produce high performance self-compacting concrete with high strengths were that contains marble powder and the costs of them starts at (548) L.E/m³. The least costs of improvement of properties of both of fresh and hardened concrete (LE/property) were these contain marble powder.
