Predicting properties of High Performance Concrete containing composite cementitious materials using Artificial Neural Networks

摘要

This paper presents properties of high performance composite cementitious systems. The properties investi-gated were compressive strength, tensile strength, gas permeability and rapid chloride ion penetration of concrete incorporating composite cementitious materials as partial cement replacement prepared with var-ious water-binder ratios. There is an interaction of PFA and SF with the level of replacement. The incorpora-tion of 8 to 12% SF as cement replacement yielded the optimum strength, permeability and chloride ion penetration values. Based on the experimentally obtained results, the applicability of artificial neural network for the prediction of compressive strength, tensile strength, gas permeability and chloride ion penetration has been established. The predicted values obtained using artificial neural networks have a good correlation between the experimentally obtained values. Therefore, it is possible to predict strength and permeability of high perfor-mance concrete using artificial neural networks.
