Curing Of Concrete Techniques Holcim Australia Pty Ltd
For proper curing concrete needs moisture. Continuity in curing is a must; alterations of wetting and drying promote the development of cracking. If during curing the concrete is allowed to dry out as may happen in hot weather the chemical stops right at the point where the concrete loses its moisture. The ideal curing temperature is 23°C. Cure concrete for at least 7 days.
CONCRETE PIPE REPAIR
match the repair material to the concrete pipe. The additive darkens the color of cement, concrete, mortar, plaster and grout mixes. The repair products are applied by hand and finished with a steel trowel to produce a smooth surface. Depending on the depth and size of repairs, the pipe either cures wet or with the aid of a curing compound.
