Silica Based Concrete Additives- Is It A Wonder Material For Construction

In the domain of construction, additives are used as they provide desired strength to concrete. Based on inputs of the concrete project concrete additives are mixed in various proportions to control setting or hardening of concrete, but silica based concrete additives have an important role to play. The properties associated with silica are way different from the rest. These additives embrace various qualities of concrete to make it durable and stronger.
 

Concrete additives and high performance
 

The high performance concrete additives have the ability to enhance durability along with strength of concrete. With construction projects on a large scale, in building bridges or towers, durability coupled with additional strength augers well for the project. In small quantities you need to add these additives to concrete. The proportion that is to be used is significant as different proportions produce different results.
 

The experienced contractors are aware of the right proportion to be used for the right job. If you mix additives more than the desired proportion it would not lead to enhanced strength. Perhaps it could be counterproductive. As the job of these additives is to control setting and hardening, varied proportions spring up with variant hardening and setting features.

Silica based concrete additives- A special additive

The silica based concrete additives is incorporated with pozzolons forming additional bonds and strengthening concrete. The pozzolons are natural silica based materials in the form of fly ash or be it volcanic ash. The ashes are not pozzolons but they contain pozzolons.
 

Pozzolons does not possess any cementing property. Generally, what the materials do is that they react with calcium hydroxide in the presence of water and form robust bonds. For this reason, pozzolons that is used in silica based additives are in great demand for the construction of dams, bridges.
