Strength Targeted PBMD of HSC based on One-parameter Bayesian Probabilistic Method

摘要

This paper is about application of recently proposed Performance Based Mixture Design (PBMD) for mix proportion design of high strength concrete (HSC) that can satisfy required performances. The PBMD method is a performance oriented concrete mix proportion design procedure easily applicable to any conditions and environments for a possible replacement to the current prescriptive design standards. Based on extensive experimental results obtained for various material and performance parameters of HSC, the application feasibility of the developed PBMD procedure for HSC has been verified. Also, the proposed PBMD procedure has been used to perform application examples to obtain desired target performances of HSC with optimum concrete mixture proportions using locally available materials, local environmental conditions, and available concrete production technologies. The validity and precision of HSC mix proportion design obtained using the PBMD method is verified with the experimental and ACI presented results to check the feasibility for actual design usage.
