ASSESSMENT OF IMPROVEMENT IN PROPERTIES OF SELF COMPECTING CONCRETE BY USING BASALT FIBRE

Concrete is widely used material in the construction industry for building structures that are ordinary to those that involve highly specialized jobs. Fiber reinforced concrete, normally aims at producing material having desirable properties. Various types of fiber shave been tried by a number of researchers in the past. In this dissertation work, composite fiber i.e. combination of equal proportion chopped basalt fibers and carbon fiber of 6 mm and 12mm length have been used by varying its percentage by weight of cement as 0.5%, 1% and 1.5% for various grades of concrete from M40and M45 to cover the largest contribution to the construction industry using Self compacting concrete as also a substantially large component of the same using standard concrete. The effect of fiber percentage of various properties of concrete like compressive strength, flexural strength, etc. has been studied. Optimum fiber percentages for M40 and M45 grades of self-compacted concrete from the view point of maximizing compressive strength has been calculated by using the curve fitting approach.
