“…The differences are also for the other quantifed elements notably that of SiO 2 , SO 3 , Al 2 O 3 , Fe 2 O 3 Na 2 O, MgO, and K 2 O, which higher than those of marble powder presented in Belouadah et al[43], El-sayed et al[44], and Onimisi et al[45]. The MgO content which has been used to discriminate marble type is also variable[45, 46]. In the calcitic type marble MgO contents is less tha 15% ; and CaO contents ranging from 50-54 wt.% ; whereas in the dolomitic type, CaO contents range from 30-31% ; and the MgO contents, from 15-21%[46].…”

This work presents the manufacture of CKD-blended cement from raw materials such as clinker, gypsum, marble and cement kiln dust (CKD) obtained from CIMENCAM Figuil, North Region of Cameroon. The raw materials were first characterized through XRF and physical properties such as fineness, consistency, setting time, and expansion were determined from the cement paste. Clinker is composed of CaO (65.30 %) and SiO2 (21.13%), with significant MgO (2.71%) Na2O+K2O (1.29%), SO3 (0.81 %) and lime saturation factor (LSF) of (97.9); which make this clinker good for cement production. Gypsum is composed of SO3 (36.32 %) and CaO (33.92 %) but contains very low proportion of impurities; it is therefore classified as low-impurities gypsum suitable for cement productions. The marble is dominantly composed of CaO (37.09 %) with significant SiO2 (7.26 %), SO3(2.40%), (2.36 %), Fe2O3 (1.82 %) and MgO (0.18 %); it is classified as low-CaO calcitic-aluminosilicate and ironsilicate bearing marble. The cement kiln dust (CKD) is dominantly made up of CaO (46.0 %) and SiO2 (11.62 %) with significantly low Na2O+ K2O (1.02 %), and SO3(2.16 %); this classifies its as low alkalies-sulfate cement kiln dust. CKD-blended cements which contains free lime (0.8-2.5, SO3 (above 1.7 to 2.5), loss on ignition (LOI), and insoluble residues (6.71-9.62 %) which increase with an increase in the proportion of CKD. The blaine specific surface area (BSSA) (4797-6346 cm2/g) and the sieved remaining proportion (26.14-30.36 %) show an increase with the proportion of used CKD; The compressive strength test was carried out at 2, 7, 28 days which shows that, the resistance depends on the proportion of the used CKD (0% control, 5%, 10%, 15%, 20%... up to 50%). Pressures of 17.5 to 11.6 MPa was obtained in 2 days, 28.9 to 20.0 Mpa in 7 days, and 35.5 to 23.3 Mpa in 28 days.

“…In the study area, there is little or no existing work published on the use of integrated GIS and RS techniques in identification of groundwater potential zone. The existing work published centered on conventional methods such as geological, hydrogeological and geophysical approaches were employed for siting boreholes for water supply [2,5,16,18,[21][22][23]. Population growth in Kogi State has raised concerns about the allocation of surface water flow and the increased demands for groundwater resources.…”

The availability of groundwater varies from region to region, place to place, sometimes within a few meters and even within the same geological formation. In the study area, an integration of various thematic maps such as geomorphologic, slope, drainage density, land use/land cover maps derived from remote sensing images, geological and lineament density maps and soil map helped in generation of groundwater potential zone map using the weighted overlay analysis in ArcGIS by assigning suitable weights on the Saaty's scale according to their importance in occurrence of groundwater. However, the assigned weights of the thematic layers and their features were then normalized by using AHP. The groundwater potential zones in the study area were grouped into four classes, and their distributions are: excellent (10.23%), good (51.35%), moderate (34.26%) and poor (4.16%). Excellent groundwater prospect map which covered only 10.23% of the study area falls within the lowlands and plains. For the accuracy of the groundwater potential zone map of the study area based on RS and GIS-based model, it was validated with the data on existing boreholes which was collated for 60 boreholes in the study area and shows positive correlation.

This work presents the manufacture of CKD-blended cement from raw materials such as clinker, gypsum, marble and cement kiln dust (CKD) obtained from CIMENCAM Figuil, North Region of Cameroon. The raw materials were first characterized through XRF chemical analyses. Chemical tests (proportion of free lime, loss on ignition, sulfate, and insoluble residues), physical tests (fineness, consistency, setting time, and expansion), and compressive strength tests were carried out on manufactured CKD-blended cements and mortars. Clinker is composed of CaO (65.30%) and SiO2 (21.13%), with significant MgO (2.71%), Na2O + K2O (1.29%), SO3 (0.81%) and lime saturation factor of (97.9); which make this clinker good for cement production. Gypsum is composed of SO3 (36.32%) and CaO (33.92%) but contains very low proportion of impurities; it is therefore classified as low-impurities gypsum suitable for cement productions. The marble is dominantly composed of CaO (37.09%) with significant SiO2 (7.26%), SO3(2.40%), (2.36%), Fe2O3 (1.82%) and MgO (0.18%); it is classified as low-CaO calcitic-aluminosilicate and ferrosilicate bearing marble. The CKD is dominantly made up of CaO (46.0%) and SiO2 (11.62%) with significantly low Na2O + K2O (1.02%), and SO3(2.16%); this classifies it as low alkalies-sulfate cement kiln dust. The proportion of free lime, SO3, loss on ignition, and insoluble residues in the manufactured CKD-blended cements increase with an increase in the proportion of CKD. The blaine specific surface area (BSSA) (4797–6346 cm2/g) and the sieved residues (26.14–30.36%) show an increase with the proportion of used CKD. The compressive strength tests carried out on the prepared brick-shape hardened CKD-cement mortars (at 2, 7, and 28 days) show that, the resistance depends on the proportion of the used CKD (0% control, 5%, 10%, 15%, 20%… up to 50%). Pressures of 17.5 to 11.6 MPa was obtained in 2 days, 28.9 to 20.0 MPa in 7 days, and 35.5–23.3 MPa in 28 days.
