MEMBRANE CURING Clause Samples
The Membrane Curing clause specifies the requirement to use a membrane-forming compound to cure freshly placed concrete. In practice, this involves applying a liquid curing compound to the surface of the concrete immediately after finishing, which forms a protective film that retains moisture within the concrete during the critical early stages of hardening. This process helps prevent premature drying and cracking, ensuring the concrete achieves its intended strength and durability by maintaining optimal curing conditions.
MEMBRANE CURING. Approved curing compounds shall be used in lieu of moist curing for achieving foolproof curing. Such compounds shall be applied to all exposed surfaces of the concrete as soon as possible after the concrete has set. Impermeable membranes such as polyethylene sheet covering closed to the concrete surface may also be used to provide effective barrier against evaporation. (Refer canal lining chapter for specifications of “Membrane-forming curing compound).
