The Suitable Industrial Application Of Kaolin
[KPANKOROGI AND IJERO EKITI]

3.0     MATERALS AND METHODS
3.1     DESCRIPTION OF THE STUDY AREAS
Kaolin samples were collected from two different locations namely: kpankorogi and ijero Ekiti.
Kpankorogi in Edu local government area of Kwara State is located in northern part of Kwara state on latitude 08052’38-6’’N and longitude 04059’55.5’’E at 72KM distance from Ilorin. The Kpankorogi area enjoys tropical climate marked by alternating raining and dry season and a mean annual rainfall of 900mm with relative humidity of about 40 percent forest tropical weathering.
The second study area is located on charnockitic bedrock, Ijero-Ekiti Kaolin site where sample B was obtained. It is located in Ijero-Ekiti Local Gorvernment Area Ekiti State on 07049149.0511 Northing and 0050 031 26.711 Easting. The site is 4kilometer away from Ijero-Ekiti Police Station. Ijero-Ekiti enjoys tropical climate market by alternating raining and dry seasons. The annual temperature ranging from 280c to 300c and a mean annual rainfall of 1500mm with high relative humidity of about 75percent favours tropical weathering.
3.2   METHOD OF DATA COLLECTION
Kaolin samples are collected from two different deposits Kpankorogi, Edu local government area in Kwara state and Ijero Ekiti, Ijero Ekiti local government area, Ekiti state.
The sampling points were appropriately located using G.P.S device. During the collection of the samples, digger and shovel were used while polythene bags were used to keep the moisture content of the samples constant. The collected samples were appropriately labeled and sent to National Geosciences Research Laboratory Agency (NGRLA), Kaduna, and the University of Ilorin Engineering Geology Laboratory for determination of chemical and engineering properties respectively.     
3.3     LABORATORY ANALYSIS
 3.3.1 WATER CONTENT DETERMINATION
The most common way of expressing the amount of water in soil is the water content. The water content, also called the moisture content, is given the symbol w and is ration of the amount of water to the amount of dry solids.

  PROCEDURES
      Four aluminum cups were marked and then weighed. Representative samples of the wet soil sample A and Sample B were placed in the cups and weighed to determine the weight of wet clay plus cup. They were then placed in the oven for a period of 24 hours (2 aluminum cup for each kaolin sample) at a temperature of 100+5c to a constant weight. After weight were removed from the oven, leave for 10min then weight the content to obtain the weight of cups plus dry sample.
     The different between the weight of the moist clay samples and weight of dry samples from the oven in the weight of water. The water content percentage is the weight of water to weight of dry sample multiply by 100.
APPARATUS
Moisture content container, oven and weighting balance.
