Abstract

A practical model for predicting compressive strength of aerated concrete based on its pore structure was proposed. The aerated concrete’s pore structure is characterized by using a MATLAB-based image analysis method. After modeling study of compressive strength, we propose a model to predict the compressive strength according to the Griffith fracture theory. Then by using complicated multiple regression analysis, we get the model between pore structure and compressive strength
