Abstract:
An outline of the best practices for measuring and mixing the ingredients for concrete and for placing the finished product. The specific objective of these recommendations is maximum uniformity, homogeneity, and quality of concrete in place. Among the topics covered are: measurement and batching of aggregates; batching cement; water measurement; mixers; charging and discharge oper- ations; mixing time; ready-mixed concrete; avoidance of separation in placing operations; vibration; and general considerations such as construction joints and forms. The report also includes illustrations of good and bad concreting practices.
