EXPERIMENTAL INVESTIGATIONS ON DISTINCTIVE CHARACTERISTICS OF REACTIVE POWDER CONCRETE

摘要

An extensive experimental study on various characteristics of Reactive Powder Concrete (RPC) cured in normal conditions is investigated. An attempt is made to investigate the influence of the ingredients of RPC on the compressive strength of RPC using 112 mixes. The study extends to understand the effects of variation in silica fume, found to be most influential ingredient, on other mechanical properties such as flexural strength, shear strength and bond strength. Of the various mixes studied, the ideal mix proportion giving suitable performance is used to conduct further tests to determine the water absorption, water permeability, sorptivity, chloride permeability, resistance against fire, sulphate attack, acid attack, alkaline attack and abrasion of RPC. Overall results highlighted the enhanced mechanical and durability properties of RPC and its compatibility with conventional concrete.
