This record is for the most effective cement setting accelerator chemical, based on comparative tests with similar chemicals.
This record is to be attempted by an individual chemical or substance.
For the purposes of the record, a cement accelerator is an admixture added to cement, mortar or concrete to increase the rate of the setting process. Types of substances are defined under the standard BS EN 934 Part 2: Concrete admixtures.
This record is measured in accordance with the standard: ASTM C403 (Standard Test Method for Time of Setting of Concrete Mixtures by Penetration Resistance)
This record is not open to chloride setting accelerator chemicals, due to its ban for use in reinforced concrete in many countries.
