The expense and inconvenience of water curing by sprinkling 24 hr a day on a project where concrete canal lining was progressing as much as 1000 linear ft per day were avoided by using sprayed curing compounds. An 8 1/2-mile section of canal was coated with a clear compound plus burlap shading for 3 days. On the next section tests showed that a white-pigmented compound eliminated the need of burlap shading. Heat reflecting characteristics of the white-pigmented compound kept concrete temperatures as low as when the clear coated concrete was shaded.
