Concrete Additives

 
The volume of the cement increases with addition of concrete in it. The concrete acts as a powerful additive in making the cement durable and sustainable from a lot of hazards. Mostly, the additives are mixed with water and chemical reactions form to make a by product which is very necessary in construction sites. Concrete admixtures increase the durability of cement and with gradual passage of time it does not wears out quickly. Admixtures have a lot of various uses as well; they are described briefly below.
 

Uses of Concrete Additives:


Concrete admixtures have a lot of uses and the hardening of the concrete is one of the main usages of these additives. They help in making the concrete hard and resistive against a lot of damage that can be caused by any natural calamity. The general behaviour of concrete is to make the cement durable and flexible; it is mostly used in liquid or powder form. In construction sites, there is tons of work which happens; these additives help in doing all these work in a faster way.
    
The dilution of the additives in the concrete should be done properly in order to make a pure mixture; this mixture of concrete and cement should be done in a proper manner avoiding various hazardous chemical reactions. There are many concreting and batch methods that one needs to follow in order to make a good mixture. Concrete additives should be used in right amount to get the proper mixture and this will thus help in having a solid base while construction work is on.
 

Types and Classifications of Additives:


There are mainly two types of additives that are found while the mixture is done, one is chemical and the other one is mineral. They are classified on the basis of the work that they perform; the concrete additives are supposed to be very specific and various types have variety of uses. In order to create a specific lump, some amount of water is added into it. The construction sites require high workability and for that adding of water is necessary.
 
In the process of concrete hydration, acceleration of the whole procedure is done by concrete additives. They are used in mostly cold seasons, the additives help in hydration at that time of the year. Accelerating additives are very useful and calcium chloride is regarded as one of the most important one. Thus working in construction sites becomes smooth with the addition of additives.
