摘要：

Optimization of mix proportions of silica aggregates for use in polymer concrete was attempted using statistical techniques. High purity silica aggregates of six different standard particle sizes were chosen for the study. Void content of 54 statistically designed combinations were experimentally determined by adopting standard technique. Using Design Expert software the results were analyzed and an optimum composition having minimum void content was achieved. The optimum combination had a correlation coefficient of 0.95782 which proved the fitness of the selected model in analyzing the experimental data. (C) 2002 Elsevier Ltd. All rights reserved.
