Abstract
Concrete is a mixture of cement, fine aggregate, coarse aggregate and water. concrete plays a vital role in the development of infrastructure buildings, industrial structures, bridges and highways etc. Leading to utilization of large quantity of concrete.The present project focuses on investigating characteristics of M25 grade concrete is choosen and aggregate mean size of 20mm is adopted Carbon fibers are added by 1% to the weight of cement.. It leads to examine the admixtures to improve the performance of concrete. The cubes, beams and cylinders are tested for both compressive, flexural, Concrete Core test, youngs-modulus strength tests were conducted for 7, 28, 56, 90 days and the results are compared to the conventional concrete. ND-Tests like rebound hammer and ultra-sonic pulse velocity were conducted. Cube specimens of size 150 mm, cylinder specimens of diameter 150,100 mm and height 300,150 mm respectively, beam specimens of size 100 mm and length 500 mm were casted.
