Abstract
A binder for hydraulic compositions comprises a water-soluble cellulose ether and a long-chain alkylbenzene-sulfonic acid or a neutralization salt thereof. The presence of the long-chain alkylbenzenesulfonic acid compound as a binder component provides hydraulic compositions with a better plasticity at a lower water-soluble cellulose ether content than when the cellulose ether is used alone as the binder.
