Abstract - Polymer concretes are composite materials
bonding of all aggregate particles will be less or use loosely packed aggregate with higher binder content [1]. Though the aggregate and micro filler form a major component of total mass of the polymer concrete, there has not been much emphasis on the aggregate and micro filler mix proportion used in such system. The aggregates used in polymer concrete are either fine particles or the particle size distribution chosen are based on theoretical basis suitable for Portland cement concretes. Also the effect of aggregate mix proportion on void content and method of optimizing mix proportion to have minimum void content has been reported [2,3]. Furan resin offer several advantages over other synthetic resin based binder system such as unsaturated polyester, epoxy etc. The major raw material used in the synthesis of furan polymer is furfuryl alcohol and furfuraldehyde which are obtained from agricultural wastes. Condensation product of furfuraldehyde and acetone in different mole ratio are more commonly used, even though other types of furan resin such as homopolymer of furfuryl alcohol or a copolymer of furfuryl alcohol and furfuraldehyde are also known to be good binder for chemical resistance application. Furan resins can be cured through heat or by addition of a chemical agent [4,5].
made of polymeric binder along with filler materials, and have excellent strength, high density and durability property along with the resistance towards chemicals. Polymer concrete mineral filler content may reach up to 95% by weight. Using different sizes of filler and poly furfuryl alcohol resin based binder; a series of polymer concrete of different composition was prepared. For each composition, compressive strength was checked in UTM. The effect of quantity of binder, curing agent and size of fillers on compressive strength of concrete is discussed. In 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 The current standard building material, namely Portland cement concrete prepared by binding aggregate with Portland cement, has a number of deficiencies which make it inappropriate for some application. For instance, a suitable cure with Portland cement takes approximately 28 days. In addition, chemical resistance to acid is lacking in Portland cement. Several attempts have been made to replace Portland cement with different building material compositions to overcome the above described problems. Such substitute materials will compromise on one property such as strength for another property such as acid resistance or the like. These substitutes have taken the form of both coating and lining for Portland cement as well as complete replacement materials. Polymer concrete is a composite material in which the aggregates are bound together in a polymer matrix. The composite do not contain any Portland cement component. Application and performance of polymer concrete is dependent upon the specific polymer binder as well as the type of aggregates and its gradation. The distribution of aggregates should be such as to allow for a minimum void volume for dry packed aggregates which will result in dense packing. Dense packing of aggregate in the polymer concrete matrix results in better properties. To achieve this, either the void content of the aggregate mix can be minimized where the binder requirement for ensuring adequate

2. EXPERIMENTAL WORK 2.1 Preparation of furan resin For manufacturing furan resin at lab level, furfuryl alcohol of Merck chemical company was used. In the process 45ml furfuryl alcohol and 1ml of O- Phosphoric acid was taken in round bottom two neck flask in which thermometer and stirrer was fitted. Flask was heated on heating mantle at continuous rate with stirring. When the temperature of reaction mixture reached between 95 to 100â °C, a sudden evolution of heat was observed and this was the point of actual reaction. Heat of the exotherm was controlled to prevent premature cross linking. The evolution of heat was successfully controlled to get furan resin of glowing colour with viscosity of about 250 cP and pH of resin was maintained between 5 and 6 by adding 1 ml of tri ethanol amine.
