Strength Improvement of Early Age Unfired Soil Lime Bricks
Despite their low performance quality and aesthetics, non-standard bricks are commonly used in the construction of low-rise buildings and rural houses in Indonesia.These bricks are produced traditionnally in home run plants with little adherance to appropriate mix designs.These unfired soil lime bricks enter the market within 2 weeks of production, which inflicts potential loss to the buyers due to their low performance quality.The paper discusses strength improvements of these early age bricks through 2 methods.The first method is by adding the optimal amount of mixing water to the soil and lime mix.The second method is by adding untreated coconut fibers with a 2.5 cm fiber length as additional reinforcements.The effect of 3%, 5% and 7% fiber addition to the mechanical properties of bricks were investigated.Laboratory tests showed that higher compressive strengths, compared to that of traditional unfired soil lime bricks, could be achieved through the 2 proposed methods.The bricks reinforced with higher percentage of untreated coconut fibers have better modulus of ruptures.
