Durability of Concrete Using Manufactured Sand as a Complete Replacement of Natural Sand with Basalt Fibers

The present investigation is an attempt to study durability properties of concrete with manufactured sand as complete replacement to natural sand and varying percentage of basalt fibers ranging from 0 to 4 kg/m3 in interval of 1 kg/m3 and aspect ratio of 20 is to be used to study the strength and durability of concrete. For present study M30 grade concrete is designed and its durability as well as workability properties are studied. Main focus of present work is to study durability properties such as Acid resistance test, sulphate resistance test, chloride resistance test, saturated water absorption test, elevated temperature test, residual compressive strength test, and to substantiate the better uses of manufactured sand and basalt fiber to enhance concrete strength and durability properties.
