5.14.6.4. Lime Concrete Lining
The use of this type of lining is limited to small and medium size irrigation channels with capacities of up to 200 m³/s and in which the velocity of water does not exceed 2 m/s (16). The materials required for this type of lining are lime, sand, coarse aggregate, and water. The lime concrete mix should be such that it has a minimum compressive strength of about 5.00 kN/m² after 28 days of moist curing. Usually lime concrete is prepared with 1 : 1.5 : 3 of kankar lime : kankar grit or sand : kankar (or stone or brick ballast) aggregate. The thickness of the lining may vary from 10 to 15 cm for discharge ranges of up to 200 m³/s. Lime concrete lining has been used in the Bikaner canal taking off from the left bank of the Sutlej.
