Experimental Study on Flexural Strength of Basalt Fiber Concrete with Phosphogypsum

Most of the research investigations were carried out by purifying phosphogypsum for the impurities present in it, Concrete had a good future and is unlikely to get replaced by any other material on account of its ease to produce , infinite variability , uniformity, durability and economy with using of basalt fiber in high strength concrete then its utilization were suggested. In another research approach phosphogypsum and Basalt fiber could be utilized without any treatment and therefore it may be entitled as untreated and impure form. The main aim of the investigation program is first to prepare the strength of concrete of grade M25 with locally available ingredient and then to study the effect of different proportion of basalt fiber in the mix and to find optimum range of basalt fiber and phosphogypsum content in the mix. The concrete specimens were tested on flexural properties of concrete and other test were conducted for cement, chemical admixture, coarse aggregate & fine aggregate. 10% and 15% of phosphogypsum has been fixed and basalt fiber is being varying on 0.3%, 0.6%, 0.9%. The properties of such cement, cement mortar and concrete mixes produced compared with conventional mixes. The conventional concrete mixes have been modified to accommodate raw phosphogypsum and basalt fiber as a part of cement to be suitable for the concrete for workability and 28 days compressive strength varying from 20 N/ mm2 to 30 N/ mm2.
