Current thermoset resin systems feature epoxy, polyurethane, acrylic and phenolic binders, which are all derived from fossil resources. With the introduction of BioRezTM, a renewable thermoset binder is now available for NFRC. Prepolymers of furfuryl alcohol are the base material of BioRezTM resins (Figure 3).
this work the binding material used is poly furfuryl alcohol, which is a thermally cross linked polymer that is synthesized from furfuryl alcohol monomer. Further FTIR analysis is done to study the polymerization of furfuryl alcohol. Keywords: Filler, FTIR, Polymer Concrete, Resin, UTM 1. INTRODUCTION

A thorough investigation of the acid-catalyzed polycondensation of furfuryl alcohol was conducted with the specific aim of understanding the mechanisms responsible for the main reaction, but more particularly for the transformation of linear unconjugated oligomers into black cross-linked final materials.
POLYFURFURYL ALCOHOL THERMOSETS RESINS IN FIRE RESISTANT COMPOSITE APPLICATIONS SUMMARY RESULTS OF THE FIRERESIST PROJECT Dr. Ir. Hans E. Hoydonckx1*, Marco Monti 2, Giovanni Camino 2,3, Pietro Di Monica 4, Conor O'Neill4 1 TransFurans Chemicals bvba, Geel, Belgium *Hans.Hoydonckx@transfurans.be
furfuryl alcohol bioresins extracted - renewable resources, such as corncobs, were from investigated. Results are compared to control specimens fabricated using conventional epoxy resin. It was shown that by careful selection of viscosity of bioresin, and type and - dosage of catalyst, similar mechanical properties to epoxy-GFRP can be achieved.
The first study revealed the positive hybridization effect of poly (furfuryl alcohol) (PFA) and epoxidized soybean oil (ESO) in improving impact strength of a biobased epoxy. The morphology study showed inhomogeneity in the structure of the biobased thermoset and it was related to the difference in curing kinetic of components.
CBD-242. Polymer Concrete. Originally published November 1985. A. Blaga, J.J. Beaudoin. Abstract. Polymer concrete (PC), or resin concrete, consists of a polymer binder which may be a thermoplastic but more frequently is a thermosetting polymer, and a mineral filler such as aggregate, gravel and crushed stone.
A polymer concrete comprising by weight about 40-70% coarse aggregate, about 20-55% of a fine aggregate such as sand, about 2-15% silica flour and about 8% to 12% furfuryl alcohol monomer polymerized in situ with an acid catalyst in amounts of about 8% to 12% by weight of the furfuryl alcohol monomer produces a highly cross-linked concrete which contains no cement and is mixed without water.

Furfuryl alcohol resins contain a broad spectrum of compounds. The distribution of these compounds in a given resin varies with the manufacturing conditions. A resin containing a high proportion of low molecular weight constituents has been prepared and separated into fractions.
Very limited studies exist on the durability of "green" biocomposites, particularly resins, in the context of structural engineering applications. This paper investigates the durability of concrete cylinders wrapped with glass fiber reinforced bioresin made from furfuryl alcohol extracted from renewable sources such as corncobs and sugar cane.
Alibaba.com offers 211 furfuryl alcohol resin products. About 23% of these are polymer, 1% are coating auxiliary agents, and 1% are water treatment. A wide variety of furfuryl alcohol resin options are available to you, such as synthetic resin and plastics, synthetic fibers.
A liquid, thermosetting resin in which the furan ring is an integral part of the polymer chain, made by the condensation of furfuryl alcohol; used as a cement and adhesive, casting resin, coating, and impregnant.
Epoxy emulsion had been prepared by emulsifying epoxy resin, based on diglycidyl ether of bisphenol A, and amino-amide based hardener in water by using a nonionic surfactant so that it can be used as polymer cement concrete . Epoxy polymer cement concrete specimens were prepared by varying the polymer cement ratio from 0% to 30% by mass of cement.
Designing and Engineering Biobased Thermosets from Epoxy Resin and Poly (furfuryl alcohol): Routes to Improve Performance by Ghodsieh Mashouf Roudsari A Thesis presented to The University of Guelph In partial fulfilment of requirements for the degree of Doctor of Philosophy in Engineering Guelph, Ontario, Canada
Traditionally concrete is a composite of cement, gravel, sand and water. Contrary to traditional concrete, the binding agent in polyester concrete is not cement but a polyester resin. Except polyester, such polymers can be used in concrete as (Poly) Methyl Meth Acrylate (PMMA), epoxy pre-polymer, and furfuryl alcohol.
Briefly, the polymer concrete of the present invention comprises about 40 to about 70% by weight coarse aggregate, about 20 to about 55% by weight fine aggregate (sand), about 2 to about 15% silica flour and about 8 to about 12% furan resin formed by the in situ polymerization of furfuryl alcohol with aid of an acid catalyst.
This study deals with the preparation of bio-based epoxy blends and of their mechanical, thermal, and morphological characterization. Thus, the commercial tetra-functional epoxy resin, LY5210, and...
The resin has small shrinkage when curing, and the curing are insolubility-melt black brittle solid, while its advantages are that the heat resistance and chemical resistance are superior to the phenolic resin and epoxy resin. The main production raw material of furfuryl alcohol resins are furfuryl alcohol, maldehyde and urea.
Also, substitution of curing agent and some part of epoxy resin (here 15%) by bio-based materials, decreases the final price of composite due to their abundance and low cost. Polymerization of furfuryl alcohol to PFA was carried out according to our group previous study . In the acidic medium, FA quickly polycondensates and converts to PFA.
Furfuryl alcohol is a chemical compound containing furan substituted with a hydroxymethyl group. It is manufactured primarily by the hydrogenation of furfural, which is produced from organic biomass material such as corncobs, sugarcane bagasse and rice hulls.
To select appropriate promoter for the preparation of epoxy resin based polymer concrete and that prepared by direct polymerization using epoxy alcohol the experiments have been conducted taking curing agent TCT at 5% and using different composition of the promoter.
Two types of bio-based resins; an epoxidized pine oil resin blend (EP) and a furfural alcohol resin (FA) derived from corn cobs and sugar cane were explored for strengthening reinforced concrete beams using externally bonded carbon and glass fiber reinforced polymer (CFRP and GFRP) sheets.
