Abstract

An aqueous dispersion containing a latex, an alkaline earth metal formiate, cellulose ether and lauryl sulphonate can be added to a concrete mixture as an auxiliary agent to make the concrete more flexible and reduce shrinkage during setting. Adding the dispersion to concrete mixtures allows also addition of fillers hitherto regarded as toxic to cement.
