PRELIMINARY APPRAISAL OF CHEMICAL AND GEOTECHNICAL PROPERTIES OF CLAY DEPOSITS IN DOMA AREA, MIDDLE BENUE TROUGH, NIGERIA

A appraisal of the chemical and geotechnical properties o f the Dorna sedimentarp claps was conducted and consequently assessed for their possible industrial potential.The chemical analpsis o f samples repealed the predominance of ) 2.04-9.01%(,1:0٤)0,94- 3.94%/,7٧40000.83-1.10%/,04000.05-0,91%( ,* 2 0 )0.21-1.82%( 4/147420) 0.08-0.18%(. The characteristic physicalparameters o f the clap specimens included linear shrinkage (3.6-15.6%), plastic limit (15 20%), liquid limit (25 41%) andplasticitp index (5 20% ). 1716 chemical and geotechnical properties o f the Dorna claps indicated that they are potentially suitable for the production o f ceramics, pottery and refractorp bricks
