Abstract
A furan polymer concrete is described comprising aggregate, acid catalyst and binder which includes furfuryl alcohol and a crosslinking monomer. The binder has a low viscosity, thereby allowing significantly less binder to be used in forming the polymer concrete.
Claims9
A polymer concrete for use in a corrosive environment comprising a nonalkaline aggregate, a furan binder having a viscosity less than 15 cps at 25.degree. C. and an acidic catalyst, wherein said furan binder comprises furfuryl alcohol, a silane and less than 25 percent by weight based on the weight of the furan binder of a cross-linking monomer selected from the group consisting of bis-phenol A, furfural, resorcinol, hydroxymethylfuran, and bis-hydroxymethylfuran.
The process for forming a bound aggregate building material composition comprising the steps of:
- a. forming a binder system by admixing monomeric furfuryl alcohol with a cross-linking monomer having a ring structure therein and crosslinkable with furfuryl alcohol, said cross-linking monomer in an amount less than 25 percent of said binder system wherein said binder system has a viscosity of less than about 15 cps at 25.degree. C.;
- b. forming a catalyzed aggregate by admixing nonalkaline aggregate and acidic catalyst;
- and
- c. admixing said binder system and said catalyzed aggregate to form a bound aggregate building material composition.
