Description: If you're designing a building or inspecting a high-strength concrete project, you need to know how the materials and methods differ from those for normal concrete. The high-strength ready mixed concrete process is explained, including: materials selection, mix design, concrete placement, and testing. Extensive information is presented on the engineering properties of high-strength concrete—strength, modulus of elasticity, drying shrinkage and creep, porosity, freeze-thaw durability, and corrosion resistance—based on the most recent laboratory data, research, and field observations. Over 30 tables, figures, and photos help describe the history, development, properties, and various projects that have used high-strength concrete.
Definition of high-strength concrete and evolution of strength classification. Materials selection for high-strength ready mixed concrete. Types, dosages, and effects of chemical and mineral admixtures, sample proportions for typical high-strength concrete (HSC) mixtures; effects of mixture components and mixing methods, placing, retempering; factors affecting strength test results including cylinder preparation/capping procedures and cylinder size. Engineering properties: detailed discussion of modulus of elasticity—both calculated and measured, strength development, drying shrinkage and creep, total strain—comparison of calculated and measured, porosity, freeze-thaw durability and corrosion resistance, thermal properties, adiabatic temperature rise, bond of concrete to steel. Discussion of DSP (densified systems containing homogeneously arranged ultrafine particles) and MDF (macro-defect free) cements. By J.A. Farny and W.C. Panarese
