This work focuses on the production of paper bricks as affordable building units. Sample preparation involved blending of cement at a proportion of 10 – 50wt.%, and sand at constant proportion of 20% in paper pulp and poured in a mould. The procedure describe in ASTM C942-99 was used for compressive, flexural and splitting tensile strength of the produced bricks using universal testing machine. Permeability test was carried out using capillary suction test in accordance with ASTM C 1585-13. Apparent porosity, water absorption and volumetric binding properties of the bricks were measured using mathematical relations. It was observed that increasing cement content brought about reduction in porosity of the paper bricks and promote dimensional stability of the bricks. The results also showed that capillary absorption reduced with increasing cement content while permeability decreased with cement content up to 40wt.%. The compressive strength of the bricks is enhanced with rise in cement content, the flexural strength increased with curing ages and splitting tensile strength increased with rising cement content at varying densities. The microstructural studies revealed significant closure of the pores thereby improved the mechanical properties and reduced water absorption capacity of the produced bricks. The research shows that there were enhanced properties in the produced composite bricks.

Corrosion behavior and Mechanical properties of Al6063 reinforced with rice husk ash (RHA) was investigated using stir casting method. The RHA was added in the variation of 3, 5, and 7 % by weight. Unreinforced samples were produced for control experimentation. Tensile strength, hardness and percentage elongation of the samples were obtained using electronic tensiometer and brinell hardness testing machine. Corrosion study of the samples was carried out using Versa-stat potentiostat with linear polarization technique. Results showed that the hardness and tensile strength of the reinforced samples decreased with increasing RHA content. Also, the percentage elongation of the reinforced samples increased slightly above the control samples. The corrosion results revealed that reinforcing 3 wt % RHA gave the highest resistance to corrosion in brine solution. Generally, corrosion rates were observed to reduce relative to the control sample.
