During the curing time period, concrete is ideally taken care of at managed temperature and humidity. To be certain complete hydration during curing, concrete slabs in many cases are sprayed with "curing compounds" that make a drinking water-retaining film around the concrete.
Compression testing of the concrete cylinder The components have an effect on the strengths of the material. Concrete toughness values are usually specified given that the reduced-bound compressive power of possibly a cylindrical or cubic specimen as based on typical exam procedures.
Examples are instantly compiled from on the net resources to point out recent utilization. Read Much more Thoughts expressed from the illustrations usually do not stand for Those people of Merriam-Webster or its editors. Send us feed-back. As the fireline is constructed, inspected or reinforced
An additional innovation in masonry development is using prestressed concrete. It's realized by possibly pretensioning or posttensioning procedures.

Following the concrete has become poured and permitted to established, the anchors are launched and, as being the steel seeks to return to its authentic size, it compresses the concrete. During the posttensioning procedure, the steel is run by way of ducts shaped inside the concrete.
