Understanding the impact of density and porosity on the thermal characteristics of kernelrazzo concrete floor finish was the study's main goal. Kernelrazzo is a combination of palm kernel shell, marble chippings in place of terrazzo, quarry dust, cement, palm oil fuel ash and water. In this study, it was determined which factors normally have the biggest influence on the thermal development of kernelrazzo concrete by conducting a scan of the literature and specifications. In this study, experiments in the laboratory were carried out at USM's HBP Concrete Lab. The components were mechanically combined in a concrete mixer with the calculated water using the Department of Environment (DoE) method. Concrete mix design for M20 grade is included in the scope of laboratory investigations. Ordinary Portland Cement (OPC), palm oil fuel ash (POFA) was used as an added pozzolana element, and quarry dust, aggregates made from palm kernel shell (PKS), and marble chippings were utilized to create the mixture. By examining kernelrazzo concrete cube samples after proper curing, the study involved estimating density, specific heat, thermal diffusivity, and thermal conductivity. Density is important to control the material's thermal characteristics of kernelrazzo concrete. Lower-density kernelrazzo concrete is a sign of more porosity. In lower-density kernelrazzo concrete, specific heat capacity, thermal diffusivity, and thermal conductivity are all decreased. There is strong relationship between thermal properties, temperature, density, water, and porosity.

Water Quality of Egbe, Ureje and Ero dams in Ekiti State was studied for a period of one year from November 2017 to October 2018. Twenty-four physicochemical parameters (temperature, conductivity, turbidity, pH, DO 2 , BOD, COD, alkalinity, turbidity, total dissolved solids, hardness, colour, phosphates, nitrates, nitrite, Cu, Pb, Mg, K, Mn, Fe, Na, Ca and Zn) were considered in the computation of Water Quality Index (WQI) based on Weighted Arithmetic Water Quality Index Method. ANOVA was used to evaluate the significant differences between water quality variables at the dams. T-test was used to show the variations of physico-chemical parameters and WQI between the two seasons. WQI in Egbe dam ranges from 118.00-164.67 (dry season) with a seasonal value of 145.69 and from 89.39-161.86 (rainy season) with a seasonal value of 120.59. In Ureje dam, WQI ranges from 101.88-164.76 (dry season) with seasonal value of 134.08 and from 96.61-138.36 (rainy season) with a seasonal value of 123.39 while in Ero, WQI ranges from 32.28-45.13 (dry season) with a seasonal value of 39.43 and from 52.12-106.22 (rainy season) with a seasonal value of 81.84. WQI of Egbe dam and Ureje dam during the dry and rainy seasons indicated poor water quality that is unfit for drinking while in Ero dam, the WQI during the dry season indicated good quality water while during the rainy season, the water in the dam was polluted. Our findings highlighted the deterioration of the dams due to anthropogenic activities and urbanization. There is an urgent need for proper management measures and suitable tools to restore the water quality of these dams. The formulas used to calculate the WQIs are easy to use thus providing a valuable tool for the accurate monitoring of water pollution in water bodies.
