Laboratory Testing
Thanks to admixtures we are able to alter the performance of concrete in ways that previously were not possible
Chemical admixtures have become an important part of everyday concrete production. There are several types of admixtures used to support the overall quality of your concrete and these mixtures require testing.
Types of Admixtures
- Water Reducing Admixtures – Low range, mid-range and high range that allow you to reduce water in concrete, therefore increasing the strength of the concrete.
- Retarding and Accelerating Admixtures allow you vary the setting time of the concrete.
- Shrinkage Reducing Admixtures are used to minimize shrinkage in concrete and subsequently the tendency of cracking.
- Alkali-Silica (ASR) Suppressing Admixtures help mitigate or suppress ASR.
- Air Entraining Admixtures which allow the concrete producer to control the amount of air in a concrete mix. The air content in concrete often determines how well it will withstand freezing and thawing
- Viscosity Modifiers – Often used for Self Consolidating concrete, pouring underwater, or creating anti-washout properties
