A Guide To The Efficient Uses Of Silica-Based Concrete Additives

These days, the need for good building materials has been increasing at an alarming rate. The reason behind this is the increasing rate of constructions in our country. And, that is where the importance of silica based concrete additives come.
 

These additives are certain materials that are mainly used to improve the properties of the concrete to a great extent. When you add them to the concrete, it either reduces its setting time, increases its setting time, improves strength, or imparts any other properties. These are the basic uses of concrete additives.
 

However, the particular silica-based concrete additive has something special to do when added in the concrete mixture. That is what is highlighted in this particular piece of writing. First, you must know the basic uses of these additives and then slowly you can proceed towards the distinct uses of these particular additives. Read on to know more.
 

Basic Uses Of Silica-Based Concrete Additives

The silica-based concrete additive is used to protect the concrete from freezing and thawing. Furthermore, it also acts as a water-reducing agent when added in the concrete.
 

Silica-based concrete additives are also used in concrete to increase workability. Also, the finish enhancement is taken care of by this particular material when it is added to the concrete mix.
 

Sometimes this particular material is added in the concrete for enhancement of early setting. Also, the permeability is reduced to a great extent when this material is used in the concrete mix.
 

Above all, it is used to make the concrete stronger and more durable than ever before. Also, if you want to reduce cracks in a structure, you can definitely use this kind of material in the concrete mix.
 

Sometimes silica-based additives are used in concrete to promote set-retardation in concrete. Thus, if you are transporting concrete over long-haul distances, make sure you add this particular material in the concrete mix.
 

Specific Uses Of Silica-Based Concrete Additive

Floor Slab Construction: The Silica-based admixture is used in the construction of the floor slab. Mainly it is used in the case of commercial buildings; however, you can also use it in case of residential buildings. Normally 5 to 7 % of admixture is used per portion of the cement content.
 

Elevator Construction: In the cases of construction of elevators of commercial and residential buildings, silica admixture is used. In this case, normally, 7 to 10% of the silica mixture is used by weight of cement.
 

Staircase: In the construction of staircases, silica admixture is used worldwide. However, the amount of the admixture must not exceed 5 to 7% of the cement weight. This particular proportion must be kept in mind while using it in the concrete mix.
 

Tunnel Construction: In earthquake-prone areas, if a construction of tunnel takes place, silica admixtures must be used in it so that it increases and doubles the strength of the concrete mix as well as the structure. 7 to 10 % is the optimum amount that can be used in the concrete mix.
