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.

Anisotropy of Concrete Strength
Cement, Concrete, and Aggregates, 1990Abstract Results obtained by numerous researchers concerning concrete strength anisotropy are analyzed. In some cases, the researchers have found that the compressive strength of specimens loaded at a right angle to a direction of concrete placing, f′c, is greater than for those loaded parallel to the above direction, f″c; in other cases,

Strength of Retempered Concrete
ACI Materials Journal, 1993A relationship is proposed for the strength of retempered concrete. This relationship is an empirical one and is obtained from an analysis of published data of retempered concrete avilable from experimental studies conducted by a number of researchers.

Concrete Strength in Structures
ACI Journal Proceedings, 1968THE SIGNIFICANCE OF CONCRETE COMPRESSIVE STRENGTH MEASUREMENT BY VARIOUS METHODS WAS INVESTIGATED. PAIRS OF SLABS FROM THREE CONCRETES WERE SUBJECTED TO GOOD AND POOR CURING. CORES AND PUSH-OUT CYLINDERS WERE REMOVED AT SIX STAGES UP TO 1 YEAR AND TESTED FOR STRENGTH. CORRESPONDING TESTS OF MOLDED CYLINDERS BROUGHT THE TOTAL SPECIMENS TO 216 CORES, 216
