In this study attention is given to the deformation performance of furfuryl alcohol polymer concrete during and directly after polymerisation. The deformation equations of ordinary Portland cement concrete are used as a model, while the appropriate adjustment is made to bring the effect of polymerisation shrinkage into consideration. Experimental work was done to determine the deformation characteristics of material samples which were exposed to various temperature conditions, while being kept free from external stresses. These conditions of varying temperature are simulations of practical applications, where the material is exposed to high and low temperatures on a cyclic basis. Results show a different deformation curve for each of the temperature conditions, which will have a definite impact on the lifecycle of the material
