INFLUENCE OF NATURAL RUBBER LATEX ON PERMEABILITY OF FIBRE REINFORCED HIGH-PERFORMANCE CONCRETE

Abstract

In order to achieve durable concrete, there are two important aspects to be considered which are durability and impermeability. To increase the demand for Natural Rubber Latex Modified Fibre reinforced High Performance Concrete (NRLMFRHPC) produced with locally available materials such as cement , Fine aggregates , coarse aggregates, Metakaolin and Crimped Steel fibers, the concrete should be made impermeable. In the present investigation, NRLMFRHPC has been produced with locally available aggregates and mineral admixture (Metakaolin) and Natural Rubber Latex based NRLMFRHPC mixes were designed by absolute volume method. The specimen of size 100mm diameter and 50mm depth were cast and cured for 28 days and then tested for durability by using “Rapid Chloride Ion Permeability Test (RCPT), to assess the permeability characteristics of NRLMFRHPC. The experimental results indicate that Natural Rubber Latex can be utilized in producing durable Fiber Reinforced High-Performance- Concrete. The various results which indicate the effect of Steel Fibers and Natural Rubber Latex on the permeability characteristics of high-performance-concrete are presented in this paper to draw useful conclusions.
