“…Similarly, atmospheric moisture absorption was tested as par [48] via a gravimetric technique. Brick samples were initially oven-dried at 110 ˚C for 24 hours, weighed in air (Wa), and exposed to a relative humidity of 80 % at 29 ˚C ± 2 ˚C (room temperature) for 24 hrs weight (Wb) was taken and moisture absorption capacity evaluated employing Equation (7).…”

Waste wigs are often disposed of in their volume in landfills, thus constituting a nuisance to the environment. Recycling these wigs in masonry bricks is a way via which they can be recycled and reused. On such premises, waste wig fiber (WWF) was recycled by incorporating it into the cement-sand-clay composite mix for masonry brick production. The challenges masonry bricks face include shrinkage and water susceptibility, hence the contributory effect of WWF on physio-hydric properties was assessed in this study. Sample preparation entailed the blending of cement, sand, clay soil, and waste wig fiber. The control mix was prepared by commixing clay with 10 % cement (by clay volume) and 20 % sand (by clay volume). Other mix proportions were reinforced with 1, 2, 3, 4, and 5 % WWF by clay volume. Prepared composites brick samples were cured for 28 and 56 days and tested for physio-hydric properties. Results revealed that WWF contributed significantly to improving hydro-resisting properties by minimizing porosity, water and moisture absorption, capillary suction, and water permeability. Furthermore, WWF contributed to dimensional stability by reducing shrinkages and weight loss. Hydration time impacts significantly in reducing apparent porosity, water permeability coefficient, moisture and water absorption, capillary suction coefficient; increasing apparent density, weight loss, linear, and volumetric shrinkage. Prolonged time in water ensued higher water absorption. The general outcome depicts that WWF showed promising performance in bricks developed in enhancing water and moisture susceptibility resistance and promoting mass and dimensional stability; hence, it can be employed in reinforcing cement adobe bricks.
