PHYSICO-CHEMICAL AND STRENGTH PROPERTIES OF SOME LOCAL MATERIALS FOR IR RIGATION CANAL LINING

Abstract

These materials were: (i) Concrete (GC): which comprised of Cement, Sand and Granite of average size
of 12 mm, in a ratio of 1:2:4. (ii) Termite Mound (TM) (iii) Clay Cement (CLC) (iv) Cementitious Clay
(CCL), and (v) Clay Soil (CLS). Laboratory analysis of the chemical and physical properties of these
materials was determined. The shear strengths and the cone indices were determined using the
compaction characteristics of the materials. The moisture characteristics of the samples show that
Concrete attained the maximum densities of 1.55 gcm^-3, 1.57 gcm^-3, 1.58 gcm^-3 at the lowest moisture
contents of 6.7%, 6.5 % and 7.0% at 5, 10, 25 blows, respectively, while the Clay - Cement attained
maximum densities of 1.27 gcm^-3, 1.30 gcm^-3 and 1.33 gcm^-3 at the highest moisture contents of 16.0%,
14% and 14.0% at the same levels of blows. The study showed that the plasticity of the materials
increased as the clay content increased, while the shear strength and cone index increased with depth and
decreased with increase in moisture content.
