Techniques and materials for internal water curing of concrete

This paper gives an overview of different techniques for incorporation of internal curing water in concrete. Internal water curing can be used to mitigate self-desiccation and self-desiccation shrinkage. Some concretes may need 50 kg/m3 of internal curing water for this purpose. The price of the internal curing water is in the approximate range 0.1–1 €/kg.RésuméL’article offre un aperçu des différentes techniques d’incorporation de l’eau de cure interne des bétons. La cure interne à l’eau peut être utilisée pour limiter l’auto-dessiccation et le retrait d’auto-dessiccation. Á cet effet, il se peut que certains bétons aient besoin de 50 kg/m3 d’eau de cure interne. Le prix de cette eau de cure interne est de l’ordre approximatif de 0,1–1 €/kg.
