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.

Development of the Strength of Concrete
1983The rate of hydration, and consequently the time-related process of strength development of concrete, depends on the type of cement used. In Fig. 2.1,1 the coefficient \( {{\beta }_{t}} = {{f'}_{{ct}}}/{{f'}_{{c28}}} \) for concrete made of normal cement (Type I), of rapid Open image in new window Fig. 2.1,1 The relations given in Fig.
