<p>Highly flexible concrete is formed from a basic mixture of the following components: an unsaturated polyester resin; a water-diluted styrene-acrylate copolymer; a caprolactone; a promoter, particularly a tertiary amine, as required; a catalyst, as required; cement; and aggregates. Such flexible concretes have various uses, particularly in constructions which are subject to relatively strong vibration.</p> |
