Experimental Study on Mechanical Properties of Basalt Fibre Reinforced Concrete
Concrete is very strong in compression but very weak in tension. However it is reported that tensile and bending strength of concrete is 10 to 15% of the compressive strength respectively. The addition of different types of fibres in concrete have significantly improves its compressive as well as tensile strength. Among the new advancement in field of FRC is the basalt fibre reinforced concrete. In the present study basalt chopped fibres were used in the concrete mixes and compressive and flexural strength of the specimens were tested. A total of 5 mixes were prepared by varying the percentages of basalt fibres on M 25 grade of concrete mix. Based on the laboratory results the compressive and flexural strength was reported to increase up to 46% and 74%. However the workability of fresh concrete mixes is not much affected by the addition of fibre content. The flexural strength of concrete is improved which shows the wide application of basalt fibres in concrete mixes for construction in various fields i.erailway, bridges, runway and tunnels.
THE PERFORMANCE OF BASALT FIBRE IN HIGH STRENGTH CONCRETE
The aim of this research was to evaluate the performance of high strength concrete(HSC) containing supplementary cementations materials.. 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 fibre in high strength concrete The main aim of the investigation program is first to prepare the strength of concrete of grade M40 with locally available ingredient and then to study the effect of different proportion of basalt fibre in the mix and to find optimum range of basalt fibre content in the mix. The concrete specimens were tested at different age level for mechanical properties of concrete, namely, cube compressive strength, split tensile strength, flexural strength, durability of concrete and other test were conducted for cement, chemical admixture, coarse aggregate & fine aggregate.
Rotating dialysis cell as in vitro release method for oily parenteral depot solutions.
The purpose of the study was to investigate an in vitro release method based on a rotating dialysis cell for parenteral oil depot formulations using different model conditions and test formulations. The total amount of drug released from the rotating dialysis cell was in accordance with the theoretical values calculated from the partition coefficients. The release rates were shown to depend on the total amount of drug available for the release process and to follow first order kinetics. The rotating dialysis cell has a potential as in vitro release method for characterization of oily depot formulations for parenteral administration.
