Abstract:Results are summarized from an experimental investigation of the properties of high strength concrete. The materials tested were produced using Tvpe I portland cement, gravel or crushed limestone coarse aggregate, sand from a local deposit, and for some mixes a water-reducing retarding admixture. Water-cement ratios ranged from 0.70 to 0.32, and uniaxial compressive strengths ranged from about 3 00 0 to 11,000 psi (21 to 76 MPa). Information is given pertaining to compressive strength, strength gain with age, specimen size effect, effects of drying, stress-strain curves, static modulus of elasticity, Poisson ‘s ra tio, modulus of ruptuie, and split cylinder strength. Significant differences were found, in some cases, between the performance of high strength and normal strength concretes. These differences should be recognized and accounted for in the design of structures. The work described is a part of a huger investigation of the fundamental and engineering properties of high strength concrete. Other aspects of the research including effects of sustained loads, microcracking, and the correlation of microcracking with short-term and long-term engineering properties will be reported in subsequent papers.
