Effect of basalt fiber hybridization on the properties of concrete with charcoal additive

Abstract

The widespread use of steel in concrete has become a challenge as the emissions of carbon monoxide during steel production pollute the environment. The use of a conventional method of reinforcement has many limitations that still affect the total arrest of the concrete issue. This research aims to identify ways in which concrete strength can be improved without the conventional method. The objective of this research was to investigate the compressive strength ($f_c$), slump value, water absorption, and density of basalt fiber hybridized concrete. Experimental methods were used where a total number of 36 concrete cube specimens were prepared. It was discovered that hybrid fiber concrete (B4) obtained the highest $f_c$ on days 7, 14, and 28 of curing at 14.473, 17.844, and 24.632 N/mm², respectively while on day 28, the $f_c$ of concrete mixes B1 was 9.330 N/mm², B2 was 16.780 N/mm², B3 was 13.991 N/mm². Hybrid fiber concrete (B4) obtained a slump value of 50 mm which is higher than the other concrete mix with B1 obtaining 25 mm which is the lowest slump value. The concrete B3 had the lowest density of 1931 kg/m³ followed by B4 concrete with 2047 kg/m³ while B2 had the highest density of 2099 kg/m³. Concrete mix B1 had the highest water absorption rate of 3.5% while B4 had the lowest water absorption rate of 1.4%. In general, B4 proved to offer better advantages over the other concrete mixes and can for flooring and crack resistance and curing.
