Studies on polymer concretes based on optimized aggregate mix proportion

摘要

Polymer concretes are composite materials made of polymeric binders with filler materials. The filler materials form the major component of the polymer concrete and the distribution of their particle size influences the properties of polymer concrete. Hence using an optimized aggregate mix proportion having least void content, a series of polymer concretes of different compositions were designed on the basis of mixture design concept of design of experiments. For each composition, compressive strength was checked at different intervals of time. The effects of variables such as binder content and curing time on the properties were discussed. Further, the compressive strength obtained were optimized and compared with the experimental data. The coefficient of correlation between the experimental values and predicted values was found to be high proving the fitness of the selected model. (C) 2004 Elsevier Ltd. All rights reserved.
