The cost of building materials is rising in Nigeria has made an alarming message to find out the sources for cheaper and locally available materials to be used in construction. If we use of floor finish made with PKS (termed Kernelrazzo) as a replacement for coarse aggregate was studied for thermal conductivity, water absorption, and impact resistance by varying the percentages of PKS and the marble chippings and granite dust. The concrete floor finish was exposed to 2.5–5.0% concentration of Sodium Chloride solution for seven days to simulate the expected service conditions of houses built along the coastline of the country. It was observed that the thermal conductivity decreased as the percentage of PKS increased, the water absorption increased with an increasing percentage of PKS while the impact resistance decreased with an increasing percentage of PKS. The optimum replacement level of PKS was found to be 20% in combination with 30% granite dust and 50% marble chippings. In general terms, the housing or shelter includes the environmental condition of the building and the social services and other qualities of the environment that contribute to making a community livable and comfortable environment.

The major challenge of accessibility to affordable housing is largely predicated on the colossal cost of conventional building materials, which accounts for 40–60% of the total construction cost of building projects and this challenge could be mitigated using durable, economical, environmentally friendly and sustainable alternatives to expensive conventional building materials. Such non-conventional building materials include: rice husk ash, corncob ash and sawdust ash as cement replacement materials, and palm kernel shells as replacement for conventional coarse aggregates (gravel, granite stone, marble chippings, etc.) in concrete production and floor finishes.
