Publication:

Symposium Papers

Volume:

Abstract:

Part I: Significant Attributes and Mix-Design Methods - A study is made of high-quality high-strength concrete, its significant attributes, mix-design methods, and application of economic-strength designs to bridge members and piles. This Part I first treats of such attributes as consistent density, compressive strength, high-early compressive strength, modulus of elasticity, shrinkage, creep, impermeability, and durability.

Abstract:

The paper reports on new prestressing tendons, which have been designed to achieve reliable bond, to guarantee corrosion protection, and to eliminate elastic and plastic slippage in anchors and couplings. Information about comparative tests on stress corrosion will be given.

SP26-17

Date: 

January 1, 1971

Author(s):

Zenon A. Zielinski

Publication:

Symposium Papers

Volume:

Abstract:

On the basis of the author's research carried on since 1957, he defines strength limits of reinforced concrete beams, and strength in inclined cracking in particular. It appears that inclined cracking due to shear does not terminate the work of the beam.
