treatment of the reactive powder concrete can result in a significant increase in compressive strength. k.m.ng et al. (2010) [4] attempt to produce reactive powder concrete using local materials under laboratory conditions. concrete designed from reactive powder concrete and high-performance concrete is experimentally
the concept of reactive powder concrete was first developed by p. richard and m. cheyrezy and rpc was first produced in the early 1990s by researchers at bouygues’ laboratory in france. a field application of rpc was done in canada and the world’s first reactive powder concrete structure, the sherbrooke bridge in canada, was erected in july 1997.
based on the experimental results, it is found that reactive powder concrete with a water-to-binder ratio of 0.2, superplasticizer dosage of 2.5%, 150600 micron quartz sand cured at 27c in water condition provides the best results in terms of mechanical and composite properties as well as for practical and economical reasons, although heat treatment of the reactive powder concrete can result
properties of rpc: the mixture design of reactive powder concrete primarily involves the creation of a dense granular skeleton. optimization of the granular mixture can be achieved by the use of packing models. coarse aggregate are replace by fine sand, with a reduction in the size of the coarse aggregate by a factor of about 50.
