Concrete is widely used material in the construction industry for building structures that are ordinary to those that involve highly
specialized jobs. Experimental work was carried out to gather information about the properties of plain cement concrete with
chopped basalt fibres. Basalt fibres have been used by varying its percentage by weight of cement as 0.65%, 1% and 1.3% for
various grades of concrete from M20, M25, M30, M35, M40 to cover the largest contribution to the construction industry using
ordinary concrete as also substantially large component of the same using standard concrete.
Effect of basalt fibre on properties of concrete like workability, compressive strength, split tensile strength and flexural strength
has been studied. Optimum fibre percentages for various grades of concrete from view point of maximizing compressive strength
have been calculated by using curve fitting approach. The drawback in the form of additional expenses to be incurred can be
compensated by reduction in the material cost.
