Concrete Additive: Detailed Information
There are additives of different kinds that are often added to concrete. This is primarily done to alter the properties of according to our wishes. Due to the slight chemical changes brought about by these additives, the concrete may show certain properties like accelerated or decelerated setting time, increase in the manageability etc.
Cost of Concrete Additives
These days, additives are more often than not added to the concrete. The concrete contractors have these concrete additives ready with them. At the time of production, these additives are added in accordance with the instructions of the buyer. These additives of concreteare found in varying price ranges. The price also varies with the quality and quantity of the mixture required.
Types of Concrete Additives
Concrete additives are of various types. The right kind of additive may be offered on the basis of the requirements:
Set Accelerating: Set Accelerating additives accelerate the rate at which the concrete sets. This is especially helpful in cases where the concrete needs to set quickly, like the public pavements that cannot be closed too long for maintenance.
Set Retarding: Set retarding additives decelerate the process of setting for the concrete. The concrete, when containing these additives, settle a lot slowly. This additive is helpful in areas that intend on combating high temperatures where the concrete settles too soon.
Water Reducing Concrete Admixtures: For concrete mixing, the quantities are very important. It ensures a perfect lump when mixed in certain quantities. But, this additive largely eliminates the measuring requirement. This additive produces an ideal consistency of lump even when the water to concrete ratio is low.
Superplasticizers: These additives are used to create long and consistent slump that ranges from 7 to 9 inches. . This is used in structures that are heavily reinforced and in places where enough consolidation by using vibration cannot be easily achieved.
