Abstract

The paper reports experimental investigations on hybrid-reinforced concrete. The proportion of basalt fiber and steel fiber was 50% respectively of the total fiber taken as sample. Effect of fiber on various strengths of concrete is studied. Fiber content varied from 0 to 4% at an interval of 1% by weight of cement. Various considerations for investigation are compressive strength, flexural strength, split tensile and bond strength. Cube of size 150 × 150 × 150 mm for compressive strength, beams of size 500 × 100 × 100 mm for flexural strength, cube of size 100 × 100 × 100 mm, cylinder of 100 mm (Diameter) × 300 mm (height) were casted. All the specimens were cured for 7 and 28 days and tested subsequently. The workability is measured with the slump-cone test. The wet and dry density at 7 and 28 days is calculated. Relation between compressive strength and all other strengths is developed. A comparison of results of hybrid fiber-reinforced concrete with that of normal concrete showed significant improvements in the results of various strengths.
