Waste Blended Interlocking Fired Bricks as Pavement Alternative

The frequency increase in the standard of living and rapid growth of civil engineering works has affected the cost of construction, rehabilitation, maintenance of roads and environmental issues such as greenhouse gas emission, energy catastrophe, natural resources exhaustion, global warming, and waste contamination. The conversion of agro-municipal solid waste materials into ash, then utilizing them in construction works help in reducing cost and environmental pollution, arising from the indiscriminate disposal of these wastes. Thus, clay samplings were obtained from 3 sites where the samplings were prominent in Abuja – Nigeria, stabilized with 3 diverse waste; waste lactose (WL), eggshell ash (ESA) and waste paper ash (WPA), before scrutinized for physicochemical and strength parameters by means of standard techniques. Results acquired were compared with EURO and ACI standard as well as subjected to variability analysis. Further findings displays triaxial experiment shows that the cohesion of the clay samples was low at the peak angle of internal friction which makes clay soil indredibly plastic, but addition of 6% Portland cement (PC), 10% Egg shell (ES), 6% waste paper ash (WPA) and 6% waste lactose (WL) reduce the plastic greatly, at significant correlation of r = 0.95, α = 0.05. XRD, XRF and FTIR investigation reveals the loss on ignition value which in turn designates that clay samplings has lesser carbonaceous substance and greater mineral matter quantities.
