Some Benefits Associated With Concrete Waterproofing Admixture

By Sandra Brown


Water is basically considered as an extremely essential component in concrete curing, placement and production. When the water completes its intended role then it no longer becomes a friend to concrete. Depending on the functions which water performs together with the exposure nature, concrete can possibly create some problems especially on wet surfaces. One of the products which is normally used to protect the structures from possible damages is the concrete waterproofing admixture.

Naturally porous material is usually prone to some cracking and more specifically concrete is viewed to be vulnerable to infiltration of water. Some of the unfortunate results of such cases are freeze damage together with deterioration more specifically due to some kind of corrosion of the steel embedded reinforcement. There exists a good number of products together with some kind of systems which are prone to some kind of damages because of water especially from sealers to membranes.

These admixtures also offer a very good surface finish. They also offer some vital additional functionalities like micro cracks self-sealing, inhibiting penetration of those materials which normally cause corrosion without forgetting opposing the hydrostatic pressure. The primary use of the admixtures is basically on building together with the construction industry.

They are normally used in construction of beams of high performance, dams together with decks in industry of construction. They are also used in the solid blocks, pile concretes, surface plasters, industrial floors, hardened floor and runway among many others. They are also used effectively in both the repair and development of the construction materials.

The exposure of solid materials to liquid materials can significantly minimize the permanence or the durability of the building. This is basically one of the reasons as to why most of the bridges together buildings maintenance cost keep on rising. The impact of toxic on the liquid substances can be significantly be reduced by the use of waterproofing technology which aims at enhancing both the lifespan and the durability of buildings and other structures and hence significantly reducing the expenses of maintenance.

The third category comprises of products which are crystalline. These are basically the hydrophilic materials which usually increase the calcium silicate hydrate density or they create crystalline deposits which prevent pores to inhibit penetration of water. These various materials can be either used alone or in a combination so as to produce different performance levels.

There also exists some latex polymer admixtures which tend to resist the hydrostatic pressure although they are not capable of bridging the cracks in the solid and thus they do not produce a waterproof concrete structures. Most of the times the admixtures are usually added to basically repair the mortars but they are not usually used in the ready mixed concrete.

It has been suggested that it is only the hydrophilic crystalline admixtures which can possibly provide the solids with the highest possible resistance to water infiltration especially when water is under high pressure. The ingredients normally react with the both the water and the cement particles so as to form crystals of calcium silicate which effectively bond with the cement paste.
