摘要

Disclosed is a method for adding an additive to a cement-like composition, preferably a concrete mixture. The method includes forming a liquid flow, preferably a water flow; feeding an additive to the system; dosing said additive to said liquid flow by feeding it transversely and/or counter-currently to the liquid flow in such a way that mixture is formed which includes said additive and nanocellulose; and adding the formed mixture as an additive to a cement-like composition.
