“…The similarity in bulk density and porosity values can be attributed to the nature of the particle size distribution of the soil fractions, which have a mixture of sandy textures. This finding was supported by [8]. conductivity values were 1.52*10-6 and 1.44*10-6 m/s, respectively, and the drainage values (Q) were 1.38 and 1.30 cm3/min, respectively.…”

Cement kiln dust and gypsum, and to assess the suitability of this mixture as a 1 cm thick layer on a dense surface in resisting external conditions and air pressure, experimental programs were conducted in the laboratory. The results indicated that cement kiln dust contributed to improving the cohesion of the sand dunes and reducing their percentage. It also increased the porosity to reach 57.5%, along with a decrease in the values of water conductivity and permeability compared to untreated soil. Furthermore, the pH and EC values showed a noticeable decrease over a period of fourteen months. On the other hand, an experiment was conducted to wash the cement kiln dust and evaluate its effect on EC values. It was found that the cement kiln dust contained easily washable salts when the washing process was repeated seven times consecutively over seven days.

“…The bacterial counts in both polluted and control soils were lower than the fungal counts in the both soils. The lower counts of bacteria compared to fungi may be as a results of nutrient status of the soil and the presence of some toxic compound which do not favour bacteria growth (Asadu and Agada, 2008).…”

A study was conducted to investigate the impact of cement dust pollution from LARFAGE cement Industry, Ewekoro on physicochemical and microbiological properties of surrounding soil microbes. The physiochemical characteristics determined were soil pH using pH meter, moisture content was determined using oven drying method, electrical conductivity was determined on a 1:1(V/V) soil/water mixture. While heavy metals contents were determined using Atomic Absorption Spectrophotometer. Microbial species were examined using disc diffusion method. The results showed that, pH of the soil ranged from 6.27±0.03- 6.47±0.03. The areas closer to the factory site (500m) had highest pH values (6.47). The soil moisture content ranged from 15.78±2.52- 9.65±1.16, with values decreasing progressively away from the factory site. The levels of heavy metals except Mg, Zn and Na were higher within the factory than in the control. Cr, Fe, Pb, Fe, Cd, Ca and Cu were significantly higher at P<0.05 in all localities than in control. Isolated microbial flora consists of 5 bacteria genera belonging to, Corynebacterium, Clostridium, Bacillus, Flarobacterium and Micrococcus, and 8 fungal genera belonging to Aspergillus, Penicillium, Trichoderma, Mucor, Nocrolia, Geotrichum, Rhizopus and Fusarium. The bacteria and fungi was influenced by the cement dust deposition. The minimum counts of bacteria 1.89±0.34 and 1.99±0.09 X 108 in polluted soil and 1.85±0.51 X 104 control soil were lower than the fungal counts 10.33±2.33 X104 – 15.00±1.15 X 104 in both soils. The lower counts of bacteria compared to fungi may be as a result of nutrient status of the soil. Microbial population diversity increased steadily away from the factory. Thus, the variation is attributed to the impact of pH and heavy metals on microbial population.

“…A study on the effect of cement dust after 25 years of cement production on soil physicochemical properties by Asadu and Agada has revealed that exchangeable Ca, Na, H, and Mg, as well as soil organic matter, were significantly higher in the affected soils than in the non-affected soils [10].
