Performance of Temperature on Compressive and Shear Strength of High Strength Fiber Reinforced Concrete

D.N. Kakade, A.P. Wadekar

Abstract


ABSTRACT
This paper presents the results of the experimental investigation of various strengths at elevated temperature of high strength fiber reinforced concrete (HSFRC). Variables considered in the research work are various strengths, temperature and fiber volume fractions. Various strengths considered for investigation are compressive strength, shear strength. Concrete mix of M60 grade and crimped steel fibers with aspect ratio 50 are used. The fiber volume fraction is varied from 1 % to 5 % at an interval of 1 % by weight of cement. Standard test specimens for compressive strengths, shear strength were cast and water cured for 7 and 28 days. It kept in oven for temperature from 100°C to 500°C for 1 hour and tested later. All the test specimens were tested according to relevant Indian Standards and standard test procedures available in the literature wherever applicable. All the strengths are found to be increased continuously up to 100°C temperature with increase in fiber volume fraction then it reduces as temperature increases. The experimental results obtained for various strengths are modeled in terms of the material properties of matrix, fiber, temperature and compressive strength. The mathematical expressions developed for various strengths are presented. The results showed that the loss of concrete strength was significant and reduced with the increase of heating temperature. The results predicted by mathematically modeled expressions are in excellent agreement with experimental results.
