Bibliography

This European Standard defines and specifies requirements and conformity for admixtures specifically intended for use in sprayed concrete.The types of admixtures covered are:set accelerating and non-alkaline set accelerating admixtures;consistence control admixtures;bond improving admixtures.Provisions governing the practical application of these admixtures in the production of sprayed concrete are not part of this European Standard.
