Concrete and Fiber Concrete Impact Strength
Materials Science Forum, 2020The results of experimental studies of the impact strength of samples of concrete and steel fiber concrete are presented. For dispersed reinforcement, three types of steel fiber were used - with bent ends, wave and flattened. Tests were conducted to determine the static and dynamic bending strength, and then - impact tests on the pendulum headstock MK ...

Strength Classes of Concrete versus Strength Classes of Fibre Concrete
Solid State Phenomena, 2016Basic characteristics of each produced concrete and fibre reinforced concrete are characterized by the compression strength recorded by the standard sets of tests performed on cylinders and cubes. In addition, for the fibre reinforced concrete, the characteristic tensile strength at formation of microcracks and cracks of standard widths is required ...

Creep of high–strength concrete and normal–strength concrete
Magazine of Concrete Research, 1991The 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.

Interface strength of High-Strength concrete to Ultra-High-Performance concrete
Engineering Structures, 2022Abstract High-Strength Concrete (HSC) has been used in the production of precast concrete structures while Ultra-High-Performance Concrete (UHPC) has been considered an option for filling the connection between HSC elements due to outstanding mechanical properties and durability.

Core Strengths of High-Strength Concrete
"SP-172: High-Performance Concrete - Proceedings: ACI International Conference, Malaysia 1997", 1999The effects of varying L/D ratios and core size on the strength of cores from large elements of high strength concrete (HSC) made both in the laboratory and field were examined. 154 cores representing 5 laboratory mixtures having moist-cured cylinder compressive strengths from 114 to 142 MPa at 5-years age and 101 cores representing actual field ...

The application of Griffith’s theory to explain failure in hardened cement paste is discussed in Chapter 4. Failure due to external loading is brought about by the spontaneous growth of the critical crack when the strain energy release rate equals the maximum rate of energy requirement. At this point the rate of energy release is known as the ‘critical

Strength Criteria for Concrete
1986A new proposed third order polynomial strength criterion, based on tensorial function theory of continuum mechanics, has been used to determine the strength parameters for concrete. A straight-forward computer program to determine the parameters and plot the strength envelope has been developed.
