emerging technologies in the concrete industry,fineness of glass powder has a significant impact on its reactivity; glass finer than 38µm satisfies the strength activity index of astm c 618 (sai>75% at 7days) and can be classified as a type n pozzolan. by further increasing glass fineness and/or heat curing, concretes with 3-day strengths surpassing that of opc concrete can be prepared..feasibility of ground alkali-active sandstone powder for,incorporation of sandstone powder resulted in higher water demand and lower strength, advanced hydration of c 3 a and c 2 s within 3days and refined pore structure. based on its manufacturing, characteristics and influence on properties of pastes, it was concluded that sandstone powder was a good selection for use in concrete as mineral admixture..

reactive powder concrete is a concrete without coarse aggregate, but contains cement, silica fume, sand, quartz powder, super plasticizer and steel fiber with very low water binder ratio. the absence of coarse aggregate was considered by inventors to be key aspect for the microstructure and performance of rpc in order to reduce the heterogeneity between cement matrix and aggregate.
what is reactive powder concrete (rpc) rpc is an ultra high strength and high ductility cementitious composite with advanced mechanical and chemical properties. there are concretes that leads the way to the achievement of the maximum compressive strength of the order 120-150 mpa.
conclusion the reactive powder concrete produced by routine concrete manufacture techniques has compressive strength above 160 mpa, bending strength above 20 mpa, fine frost resistance, and impermeability of chloride. the sidewalk flat system produced by the reactive powder concrete has light deadweight, low cost, and the littler workload, which makes it suitable for bridge and
