This guide presents information on selection and use of normal weight aggregates in concrete. The selection and use of any aggregate in concrete should be based on technical criteria and moderated by economic considerations and knowledge of types of aggregates generally available in the area. The properties of aggregates influence the properties of both hardened and plastic concrete. The processing and handling of aggregates effect the properties of freshly mixed and hardened concrete. The effectiveness of quality control procedures will have an effect on batch-to-batch or day-to-day variation in the properties of concrete. Aggregates which do not comply with all the normal specification requirements are discussed as marginal aggregates. Materials that could be recycled or produced from waste products are potential sources of concrete aggregates. [ABSTRACT FROM AUTHOR] |
