JTRP Technical Reports
This is Volume 2 of the Final Report for the project titled “Performance-Related Specifications for Concrete-Bridge Superstructures” dealing with the topic of High-Performance Concrete (HPC). The investigation of high-performance concrete included the development of optimized concrete mixtures and identifying their performance characteristics related to durability for the purpose of using these characteristics in performance–related specifications in the state of Indiana. The research effort described in this report was divided in two phases. Phase I was focused on development of concrete mixtures optimized with respect to selected performance-related parameters. During this phase, ten optimum concrete mixes have been identified from 45 …
Prediction Of Splitting Tensile Strength Of High-Performance Concrete, Hilmi Mahmud
Prediction Of Splitting Tensile Strength Of High-Performance Concrete, Hilmi Mahmud
Hilmi Mahmud
Splitting tensile strength (STS) is one of the concrete mechanical properties that are used in structural design. It can be related to numerous parameters, which include compressive strength, water/binder (W/B) ratio and concrete age. Until now, most researchers estimated the STS directly from compressive strength data. This paper suggests formulae that relate STS with that of compressive strength, W/B ratio and concrete age. The predicted STS can be obtained accurately using these formulae. It is proposed that the equation with the concrete age (t) parameter be used in predicting the STS of high-performance concrete (HPC). © 2002 Elsevier Science Ltd. …
