Polymer Concrete Creep in Air and Aqueous Environment,

Pagination or Media Count:
Polymer concretes, using furfural-acetone FA monomer and modified FA monomer with and without sodium fluosilicate additive, were tested in air and aqueous environments under bending stresses. Considerable creep and some failure in the air environment were reported, as well as considerably more extensive sagging and failure in water. The latter was explained as due to water being a polymerization reaction inhibitor and by reactions promoted by the high hygroscopicity of the benzenesulfonic acid catalyst. Modified FA monomer polymer concrete with fluosilicates increases strength and reduces creep, but further research is needed.
