Description: Definitive reference on concrete technology covers fundamentals and detailed information on freshly mixed and hardened concrete. Extensively updated and expanded, this new edition discusses materials for concrete, such as portland cements, supplementary cementing materials, aggregates, admixtures and fibers; air-entrainment; procedures for mix proportioning, batching, mixing, transporting, handling, placing, consolidating, finishing, and curing concrete; precautions necessary during hot- and cold-weather concreting; causes and methods of controlling volume changes; commonly used control tests for quality concrete; special types of concrete, such as high-performance, lightweight, heavyweight, no-slump, roller-compacted, shotcrete, mass concrete and many more. Applicable ASTM, AASHTO, and ACI standards are referred to extensively.
New chapters include information on supplementary cementing materials, fibers, and HPC. Revised technical information is based on the latest ASTM, AASHTO, and ACI specs and standards, including metric values. The standards are referred to extensively.
Topics include portland cement manufacture, types (including blended hydraulic cements), and chemical composition.
Cement fineness, soundness, setting time, compressive strength, and heat of hydration are also covered. Describes supplementary cementing materials such as fly ash, slag and silica fume. Gives tolerable impurity levels in mixing water. Discusses coarse- and fine-aggregate grading, shape and surface texture, unit weight, specific gravity, absorption, freeze-thaw resistance, abrasion resistance, alkali reactivity and thermal properties.
Properties of air-entrained concrete and factors affecting air content are also covered, including the effects of air-entraining agents, water-reducers, retarders, and accelerators. Sections on proportioning from field data and trial mixtures give numerical examples. Effects of water-cement ratio, cement content, and air content are illustrated. Production topics include batching, mixing, transporting, and handling.
Construction topics include forms, placing, vibration, finishing, jointing,and curing. Hot- and cold-weather concreting, including effects of temperature extremes on concrete properties.
Volume changes caused by loads or by temperature or moisture content variations. Describes tests for slump, air content, temperature, and unit weight of fresh concrete, plus strength, durability, and permeability of hardened concrete. Nondestructive tests are also described.
Special concretes are discussed; high-performance concretes are covered in detail.
Includes eighteen chapters and a comprehensive index.
