1/5/2008 · Batching is the process of weighing and introducing into the mixer the ingredients for a batch of concrete. All raw materials, cement, aggregates, water and admixtures are weighted and batched, at the aggregate and cement weigh hoppers and at the admixtures reactor respectively.
It is well known in concrete technology that the grading of aggregate is one of the main factors influencing the hardened concrete strength (Neville, 1995; Kumar Mehta and Paulo Monteiro, 2006). Aggregate is added to cement paste for various reasons: aggregate is cheaper than cement and it confers to concrete higher strength and better durability than cement paste.
