Britain's newest and largest plant in Fulham is operated by Britain's oldest and largest producer, Ready Mixed Concrete Limited. The new plant operates on the automatic batching and mixing principle and has an output capacity of 3 cubic yards of ready mix per minute. Quality control is insured by frequent slump tests. Cubes are made from both random and representative loads. Most of this work is undertaken for the company's own benefit although results can be supplied to the customer.
