The specification, production, and delivery of concreteare achieved in different ways. The basic processes andcommon techniques are explained here. ASTM C 94 pro-vides standard specifications for the manufacture anddelivery of freshly mixed Concrete . Standards of theConcrete Plant Manufacturers Bureau, Truck Mixer Manu-facturers Bureau, and Volumetric Mixer ManufacturersBureau can be found on the National Ready MixedConcrete Association s website at options for ordering or specifying Concrete aredescribed in ASTM C 94:1. Option A is performance based.
Batching, Mixing, Transporting, and Handling Concrete percentages of accuracy: cementitious material ±1%, aggregates ± 2%, water ±1%, and admixtures ± 3%. Equipment should be capable of measuring quanti-ties within these tolerances for the smallest batch regu-larly used as well as for larger batches (Fig. 10-1). The
