| Abstract |
There are many advantages of the use of high-strength concrete. It can reduce the width of column, weight of structure, and increase durability. Most of studies on high-strength concrete have been concentrated on the effects of mix proportion, constituents and curing, but a few study of strength estimation which is important for quality control of concrete has been implemented.
Data on mix designs and the results of quality test of high-strength concrete, used in this study, are taken from RMC plants. Adjusted binder-water ratio theory is used for considering the relation of compressive strength according to replacement and mixture factor. This study suggests compressive strength estimation equation of high-strength by using multiple linear regression analysis. |
