Mechanical Properties of High-Strength Concrete
The objective of the research was to investigate the effects of various test and material variables on the mechanical properties of high strength concrete. The main test variables included: mold material; mold size; specimen and condition; curing condition; heat-curing temperature; and age. The material variables investigated were: total cementitious material content of the mix; percent replacement of cement by weight with fly ash, silica fume or their combination; type and gradation of coarse aggregate; type of superplasticizer; and type and brand of cement. Efforts were made to use materials and procedures considered typical of those used by the precast/prestressed industry. In addition, standard tests were conducted on companion specimens to correlate the results of this study with results reported elsewhere in the literature. High strength concretes with 28-day compressive strengths in the range of 8,000 to 18,600 psi (55.2 to 128 MPa) were produced.
