PRECAST CONCRETE PROCESS - The Constructor

PRECAST CONCRETE PROCESS. A large number of concrete structures (about 6% of the building frame market) are precast. The individual components are prefabricated off site then taken to site where they are erected. The following figures illustrate the precast concrete process: 1. Production of reinforced cages and main connections: The precast factory often has specialist workshops for the

Concrete: Manufacturing Process - BrainKart

The process of keeping concrete damp for this purpose is known as curing. The object is to prevent the loss of moisture from concrete due to . evaporation or any other reason, supply additional moisture or heat and moisture to accelerate the gain of strength. Curing must be done for at least three weeks and in no case for less than ten days. Approximately 14 litres of water is required to

How to Make Cement And Concrete From Scratch

To make concrete though which will greatly extend the volume produced you mix in gravel or sand or crushed brick. Proportions are an endless subject of debate but the formula of 1 part cement, 2 parts sand and 3 parts gravel by volume is a good starting point. Mix the dry ingredients first and then slowly add water. You want "workable" concrete.
