Concrete block is one of the most famous construction materials nowadays because of its excellent strength and resilience. Load-bearing block is a type of concrete block that is used to carry the weight of all of the elements above it and pass it down to a single foundation. However, concrete block is prone to cracking. Cracking in load-bearing block walls represents a serious structural deficiency that demands prompt engineering evaluation. In this study, steel fiber is used to improve the strength, durability, and crack resistance of concrete, making them suitable for various construction applications. This study aimed to compare the strength of traditional load bearing blocks against Steel Fiber Reinforced Concrete (SFRC) load bearing blocks. The content of steel fiber tested were 2%, 2.5%, and 3% of the cement volume. A compressive strength test was done to compare the load bearing capacity and compressive strength of the control and SFRC load bearing blocks. One-way ANOVA test was used to analyzed the result. The results indicated that the addition of steel fibers had the effect of increasing the maximum failure load and compressive strength of concrete for each curing time, and that the greater the fiber content was, the better the performance was. The results show that the presence of steel fibers, especially at 3% volume fraction, significantly enhanced the structural behaviour of concrete blocks with the largest statistical impact at the earliest curing age of 7 days, and that this reinforcement technique provides an effective way of improving the strength properties of concrete building materials.
