Abstract

This paper examined the comparison between the mechanical properties of slurry infiltrated fibrous concrete with short steel fiber and discrete bamboo. The differences in properties of the concrete with fiber, concrete without fiber and concrete with discrete bamboo was determined. Compressive and flexural strengths of concrete and slump were also determined. A total of six mix batches of concrete containing 0% (control), 1%, 2% and 3% of steel fiber and discrete bamboo was incorporated into concrete, while 0%, 0.5%, 0.75% and 1.0% of steel fibre and discrete bamboo by volume fraction of concrete were used for flexural strength test. The bamboo stripes were sun dried, cut in sizes ranging from 50-63mm in length and 4.4mm thick for easy mix with concrete while the steel fiber was 25mm in length and 0.4mm thick. The concrete prism used was 300mm x 100 mm x 100mm for compressive strength test and beam 350mm x 100mm x 100mm for flexural strength test. A thickness of 10mm cement slurry was infiltrated into the beam prism while the remaining 90mm thickness was filled with concrete. Plain concrete without fiber or discrete bamboo served as control. The addition of steel fibre increased the strength of concrete.
