One of the most commonly used materials for binding in the construction industry is cement. When cement is mixed with water, stone chips and sand, we get what is known as concrete. Another common term used by cement contractors happens to be admixtures.
What are admixtures and why are they used by cement contractors?
They are chemicals added to concrete in the initial stages of mixing to enhance or modify the properties of the mix. Concrete admixtures are mostly used by concrete contractors in Brooklyn and the surrounding areas to enhance durability, strength and to reduce water content in the mix.
A number of admixtures are available, which have been classified according to their applications. For instance, there are plasticizers and super plasticizers (water reducing agents), followed by air entrainers, retarders, and accelerators.
In the market, three types of admixtures are commonly used. These include Sulfonated Naphthalene Formaldehyde (SNF), Polycarboxylate Ether (PCE) and Sulfonated Melamine Formaldehyde (SMF) based admixtures. The extent to which these admixtures are to be used depends on a number of factors including the amount and types of cement, the temperature of air, concrete and water content.
For concrete contractors of Brooklyn and the surrounding areas such as Manhattan, the Staten Island, the Bronx and Queens, admixtures provide a variety of benefits such as reduced permeability, resistance to corrosion and chemical attack, placement of concrete underwater and in harsh weather conditions.
The demand for concrete admixtures is related to the cement consumption trends.
Some of the factors responsible for driving the production of admixtures include the increasing quality of construction works and the accelerated growth rate of construction of bridges, dams, roads and tunnels.
In recent times, developments have been made in admixture technology, which have led to the development of a new range of water reducers. There are admixtures, used by concrete contractors which have recycled material up to a staggering 85%.
Concrete admixtures have evolved over the past few decades with the growth of the construction industry. As new construction techniques are devised, concrete admixtures are becoming more stable and environment-friendly than before
