In order to investigate the influence of various parameters on compressive strength and fluidity reactive powder concrete (RPC) made from local materials, 22 groups RPC cubic specimens 3 prism were designed, main included water binder ratio, ratio silica fume cement, slag quartz sand volume fraction steel fiber, steam curing time. The stress-strain curves failure mode obtained by axial compress...

Glass is needed in several forms in today’s life. Its life is limited, and after use it is either stored into sharp edged or sent to landfills. As we know glass is non-biodegradable, landfills does not recommend any environment friendly solution. In India as a most developing country, facing shortage of post consumer’s disposal waste site and it’s become very serious problems. Hence, there is s...

Self – compacting concrete (SCC) is a high – performance concrete that can flow under its own weight to completely fill the form work and self-consolidate without any mechanical vibration. Such concrete an accelerate the placement, reduce the labor requirements needed for consolidation, finishing and eliminate environmental pollution. Oyster shell were collected from river and sea & it produced...

This paper aims at investigating the influence of partial replacement of Portland cement with ultrafine fillers compared to limestone powder on the durability and mechanical characteristics of concrete. For this purpose, ultrafine calcium carbonate materials with different specific surface areas of 9.7 and 15.1 m2/g and limestone powder (0.72 m2/g) were used. The results indicate that the ultra...

This paper presents an experimental investigation of the effect impact force on residual strength capacity simply supported reactive powder slabs. Eight specimens reinforced concrete slabs with dimensions 500 x mm and 70 in four categories were used. The influences slab compressive (conventional concrete), steel fiber proportion (1, 1.5, 2%), percentage reinforcement tension zone (ρ1=0.007, ρ2=...

Reactive Powder Concretes (RPC) are well known for their exceptional strength properties and durability properties. The use of Supplementary Cementitious Materials (SCM) is the best way to enhance characteristics RPCs further. Among various SCMs, potential Ground Granulated Blast-furnace Slag (GGBS) proven by many researchers. However, effect GGBS on fracture toughness RPCs, especially under te...
