aditive

is component of organic nature (resins) or inorganic, whose inclusion has as object to modify the physical properties of the materials by means of chemical components

Relation of additives with the construction

the additive chemical agents makes possible that the constructive systems that they offer special characteristics or necessities, can be made with the Maxima guarantee. Slope that implies so much an improvement of the benefits of the raw materials, as well as the prevention and eradication of the work to assure a greater durability throughout the life utility the building and, therefore, a greater saving of costs.

ACCELERATING ADDITIVES

Substance that reduce the normal time of hardening of the cement paste and/or accelerate the normal time of development of the resistance.

REDUCING WATER ADDITIVES - PLASTIFICANTES.

They are organic and inorganic compounds that allow to use minor water of which it would be used in normal conditions in the concrete one, producing better characteristics of trabajabilidad and also of resistance when being reduced the Relation Water/Cement.

DELAYING ADDITIVES

Have as objective to increase the time of normal hardening of the concrete one, with a view to having a period of plasticity greater than it facilitates the constructive process.

CHEMICAL CURADORES

Although they do not fit within the classic additive definition, because do not react with the cement, constitute products that are added in the surface of the concrete one drained to avoid the loss of the water and to assure that the necessary humidity for the hidratación process exists.
