Use of Water Reducers, Retarders, and Superplasticizer

Use of Water Reducers, Retarders, and Superplasticizers. Introduction. Many important characteristics of concrete are influenced by the ratio (by weight) of water to cementitious materials (w/cm) used in the mixture. By reducing the amount of water, the cement paste will have higher density, which results in higher paste quality.

Concrete Temperature Monitoring in Mass Concrete | Giatec ...

Jul 10, 2017 · This can be done with the use of chilled water, ice, or liquid nitrogen. Temperature regulation can also be done throughout the project by running cool water through cooling pipes which are installed before the concrete placement. In order to know when it is appropriate to undertake cooling processes, temperatures must be monitored in real-time.

Radiant Cooling | Department of Energy

Radiant cooling systems have been embedded in the ceilings of adobe homes, taking advantage of the thermal mass to provide a steady cooling effect. Homes built on concrete slabs are prime candidates for radiant heating systems , and radiant floor cooling takes advantage of the same principle using chilled water.

Why Are Concrete Walls a Good Insulator? | Hunker

Concrete by itself has a very low R-value, a measure of thermal resistance. Its insulation value comes primarily from using it in thick slabs, and hence isolating the insulated space from thermal fluxes in the environment.

Cooling Concrete with Liquid Nitrogen| Concrete ...

One traditional approach to lowering concrete temperatures is to use ice to supplement a portion of the batch water. However, this at times leads to operating and quality control problems. An alternative to ice for providing necessary cooling is to use liquid nitrogen (LIN), an inert liquid with a temperature of -320 degrees F.

Using Crushed Ice in Concrete| Concrete Construction Magazine

The use of ice does effectively accomplish the purpose of cooling the mix in hot weather and is far more effective than cold water. One rule of thumb for determining how much ice to use is that the concrete temperature can be reduced one degree F for each two percent of total water replaced by ice.

The water temperature must be monitored, recorded, and maintained at the same 23.0±2.0°C (73.4±3.5°F) level as moist rooms. Tanks can also be added and interconnected for greater sample capacity and heating/cooling efficiency. Accessories for heating and circulating the curing water make it easier to maintain specified temperature levels.
