High strength concrete project
WebFor concrete strength less than 3,000 psi, f’ cr = f’ c + 1000psi. For concrete strength between 3,000 psi and 5,000 psi (inclusive), f’ cr = f’ c + 1200 psi. For concrete strength greater than 5,000 psi, f’ cr = 1.10 f’ c + 700 psi. For example, for 6,000 psi concrete, the required average compressive strength of the trial mix must be at least: WebSep 1, 1996 · DOI: 10.14359/9854. Date: 9/1/1996. Abstract: This paper presents an experimental study of early-age tensile strength (i.e., modulus of rupture) of low, medium, and high-strength concretes. In this study, low strength indicates a 28-day concrete compressive strength of 30 MPa (4300 psi), medium strength indicates a 28-day …
