Concrete plant - Wikipedia
A concrete plant, also known as a batch plant or batching plant or a concrete batching plant, is equipment that combines various ingredients to form concrete.Some of these inputs include water, air, admixtures, sand, aggregate (rocks, gravel, etc.), fly ash, silica fume, slag, and cement.
Batching, Mixing, Placing and Compaction of Concrete
Batching is the process of measuring concrete mix ingredients either by volume or by mass and introducing them into the mixture. Traditionally batching is done by volume but most specifications require that batching be done by mass rather than volume. Percentage of accuracy for measurement of concrete materials as follows.When the quantity of cement to be batched exceeds 30% of scale capacity, the measuring accuracy should be within 1% of required mass. If measuring quantity is less than 30%...

STRUCTURE magazine | Ensuring Quality Concrete
Unfortunately, when transit time to the site is excessive, and a loss of slump occurs by the time the concrete is ready to be placed on the site, the most common response is the addition of water. Occasionally, due to long travel times, a concrete batch plant will send a truck with less than the prescribed amount of water.
Use of Water Reducers, Retarders, and Superplasticizer
The extended-set admixture is widely used as a stabilizing agent for wash water concrete and fresh concrete. Addition of extended-set admixture enables the reuse of wash water to the next batch without affecting concrete properties. This admixture can also be used for long haul concrete delivery and to maintain slump.
Strength development in concrete - Understanding Cement
The rate at which concrete sets is independent of the rate at which it hardens. Rapid-hardening cement may have similar setting times to ordinary Portland cement. Measurement of concrete strength. Traditionally, this is done by preparing concrete cubes or prisms, then curing them for specified times. Common curing times are 2, 7, 28 and 90 days.

Making use of recycled concrete aggregates (RCA) has thus been a subject of investigation for a long time (Ravindrarajah et al., 1985; Nixon, 1978; Frondistou-Yannas, 1977). These studies often conclude on the fact that concretes produced with RCA had lower compressive strength and elastic modulus than normal concrete (Frondistou-Yannas, 1977).
