Concrete Technology in Focus - Master Builders Solutions

A Concrete Batching Plant is a machine to make Concrete from its fixings viz Cement, Crushed Stone, Sand, Water and Admixture Chemicals. At times added substances like GGBS (Ground granulated impact Furnace Slag), Fly Ash or Micro-silica are added to change the qualities of the finished result. The word Batching Plant originates from "Batch", which basically implies that solid is made in measured washes inside a Concrete Batching Plant.
