A METHOD AND AN APPARATUS FOR ADDING AN ADDITIVE TO A CEMENT-LIKE COMPOSITION

摘要

The invention relates to a method for adding an additive to a cement-like composition, preferably a concrete mixture. The method comprises forming a liquid flow (A), preferably a water flow; feeding an additive (9) to the system; dosing said additive (9) to said liquid flow (A) by feeding it transversely and/or counter-currently to the liquid flow (A) in such a way that mixture is formed which comprises said additive and nanocellulose; and adding the formed mixture as an additive to a cement-like composition. Furthermore, the invention relates to a cement-like composition and to an apparatus for adding an additive to a cement-like composition.
