Theoretical study of similar experimental method for durability of concrete under artificial climate environment

Abstract

Based on the similarity theory, a new experimental method named Similar Experimental Method for Durability of Concrete (SEMDC) was established. The existing experimental methods for durability of concrete were summarized, and the merits and demerits of these experimental methods were analyzed. Major factors affecting the durability of concrete were found through literature review. These factors were analyzed and the similarity criteria were established according to the similarity theory, and then the SEMDC was established according to the rules of these criteria. The various influential factors of the experimental method were analyzed and the merits and demerits of this new experimental method were discussed. According to SEMDC, changing the geometry shrinkage ratio was the only way to accelerate the test in order to keep the experiment similar to the reality. There were few other parameters which need to be changed in SEMDC, making the test easy to be achieved. According to SEMDC, time shrinkage ratio was the square of geometric shrinkage ratio, so an appropriate increase of the geometric shrinkage ratio could accelerate the test. Finally, an example of experimental design for durability of concrete was devised theoretically base on SEMDC theory.
