Concrete Clips: Internal Curing

Concrete Clips is a series of informational videos developed by FHWA. Internal curing is a method of water curing concrete. Unlike conventional curing that supplies water from the surface of concrete, internal curing provides the curing water from the porous aggregates that are mixed into the concrete mixture for the purposes of providing the cure water.

ASTM C173 Volumetric Air Meter Test Video

This video demonstrates ASTM C173, the Standard Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method; it is commonly referred to as the Roll-a-Meter test. The Volumetric Air Test method covers the determination of the air content of freshly mixed concrete. It measures the air contained in the mortar fraction of the concrete; it is not affected by air that may be present inside the porous lightweight aggregate particles.

Centrifuge Test for Internal Curing Lightweight Aggregate

This video demonstrates the centrifuge test for internal curing moisture testing with lightweight aggregate.

Expanded Shale Used in Major Water Tank Replacement Project

ESCSI, in conjunction with Trinity Lightweight, has released a new video detailing the use of internally cured concrete in a long-term water tank replacement project in Denver, Colorado. The public utility is in the midst of a 10-year $120-million dollar project to upgrade water storage facilities across the city. The video, featuring engineer Erik Holck, explains why internally cured concrete is the product of choice to build new massive multi-million gallon tanks used to store Denver’s treated water.

Internally Cured Concrete Part One: Lightweight Aggregate Preparation, Moisture Testing and Mix Design

This video is part one of a two-part series on how to easily produce internally cured concrete.

New Developments in Lightweight Concrete Masonry and How They Benefit the Mason Contractor

This Mason Contractors Association of America (MCAA) webinar discusses new developments in lightweight concrete masonry. Structural value has increased, energy savings have increased, and productivity potential has increased, benefiting both the mason contractor and owner.

Internally Cured Concrete Part Two: Plant Charging and Batching Considerations.

This video is part two of a two-part series on how to easily produce internally cured concrete.

Lightweight Block Survey with Mason Contractors Video

In late 2014, a survey was conducted in conjunction with the Mason Contractors Association of America to learn first-hand about contractor opinions on lightweight concrete masonry. When contractors were asked why they prefer lightweight block, safety…and the reduction of injuries on the job…were mentioned more often than reduced labor cost. Running a close third place, behind safety and productivity, was mason satisfaction.
