CEMENT ADDITIVE. |
| abstract |
The present invention relates to a cement additive, which comprises a copolymer of the polycarboxylic acid type and / or a salt thereof and a polyalkylene glycol derivative, characterized in that said polycarboxylic acid type copolymer contains at least one or more species of copolymers. composed of at least one monomer of the unsaturated polyalkylene glycol type and a monomer of the unsaturated mono or di-carboxylic acid type as its monomer components. The concretes in which the additive is used, have excellent flow, without significant retarding effects, and a slow air intake. When used with concrete for steam healing, they allow the first removal of work form. |
