5.Characteristics of Concrete 91 Chapter 9 Characteristics of Concrete Concrete is a stonelike material that forms when a carefully proportioned mixture of cement, FA, CA, and water harden into the specific shape or dimension of a structure Most of the material in concrete is FA and CA, and cement and water interact to bind the aggregates into a solid mass By adjusting the proportions of the

6.For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categoriesfine and coarse Fine aggregates generally consist of natural sand or crushed

7.A concrete plant consists of large storage hoppers for various reactive ingredients like cement, storage for bulk ingredients like aggregate and water, mechanisms for the addition of various additives and amendments, machinery to accurately weigh, move, and mix some or all of those ingredients, and facilities to dispense the mixed concrete, often to a concrete mixer truck

8.Aggregates must conform to certain requirements and should consist of clean, hard, strong, and durable particles free of chemicals, coatings of clay, or other fine materials that may affect the hydration and bond of the cement paste The characteristics of the aggregates influence the properties of the concrete

9.Designing Concrete Mixtures There are three phases in the development of a concrete mixture: specifying, designing, and proportioning ACI Mix Design The most common method used in North America is that established by ACI Recommended Practice 2111 Any mix design procedure will provide a first approximation of the proportions and must be checked by trial batches Local characteristics in
