Compressive strength of heated high-strength concrete

Magazine of Concrete Research, 2007
The present study is aimed to study the effect of elevated temperatures ranging from 50 to 250°C on the compressive strength of high-strength concrete (HSC) of M60 grade made with ordinary portland cement (OPC) and pozzolona Portland cement (PPC). Tests were conducted on 100 mm cube specimens. The specimens were heated to different temperatures of 50,

Using silica mineral waste as aggregate in a green high strength concrete: workability, strength, failure mode, and morphology assessment

Australian Journal of Civil Engineering, 2018
Environmental degradation is a major challenge in the developing countries, which are caused due to unmanaged solid waste, or improper disposal. This study investigates the effect of using silica mineral waste (eco sand) as aggregate in a green high ...

Ultra High Strength Concrete

PCI Journal, 1967
A COMMISSION WAS ESTABLISHED ON METHODS OF ACHIEVING HIGH- STRENGTH CONCRETE TO FIND OUT WHETHER THE EFFECTIVE COMPRESSIVE STRENGTH OF CONCRETE CAN BE SUBSTANTIALLY INCREASED SO THAT PRESTRESSED CONCRETE MAY BECOME NOT MERELY AN ECONOMIC STRUCTURAL MATERIAL OF ATTRACTIVE CHARACTERISTICS, BUT A MATERIAL OF HIGH SPECIFIC STRENGTH AS WELL.

Creep of high–strength concrete and normal–strength concrete

Magazine of Concrete Research, 1991
The development and use of high–strength concrete has been evolutionary. High–strength concrete is used for tall buildings, bridges, long–span structures and offshore platforms. Very little information is available on the creep of high–strength concrete compared with that of normal concrete at room and low temperatures.

High-Strength Concrete in Ultimate Strength Design

Journal of the Structural Division, 1978
The ultimate behavior of concrete structural members was predicted based on the knowledge of the concrete and the steel stress-strain curves and using nonlinear computerized methods. The calculated values of ultimate moment and curvature were compared with some experimental values for beams and columns.

Shear strength of high strength concrete beams

1991
This brief article investigates the shear strength of high strength concrete beams with and without stirrups. Thirty three beams, (of which 12 were without stirrups), having compressive strength in the range of 64 to 90 MPa were tested. The following variables were considered: concrete strength; shear span to effective depth ratio (a/d); and the amount
