- Abstract
- Increasing need for ultra-high-strength concrete as a primary structural material in high-rise building construction has underlined mechanical properties of ultra-high-strength concrete as one of the key consideration in design. Unfortunately, current code provisions are the results of tests done on normal strength concrete or high-strength concrete and these provisions may neither be adequate nor safe for structural member with ultra-high-strength concrete. Accordingly, regression analysis was carried out using experimental data from this study and data from the literature and prediction equations for mechanical properties such as compressive strength gain with time, splitting-tensile strength, flexural strength, modulus of elasticity, and poisson's ratio were proposed. The reliability of the proposed equations were assessed by R2 value and the proposed equations have been found to give a good representation of the actual mechanical properties of concrete. The validity of equations recommended by KCI 2007 for estimating mechanical properties of concrete can be extended for high-strength and ultra-high-strength concrete with average compressive strengths ranging between 55 and 220MPa.
