Gypsum fluidizer Superplastyfikator CA40 FF

The CA40 FF Superplastyfikator belongs to the group of surfactants and as such consists of a hydrophobic organic chain and a hydrophilic inorganic sulfone group. Therefore, the mechanism of its operation is based mainly on the principle of electrostatic repulsion between like charges (sulfone groups) that appear on cement or gypsum grains after adsorbing product particles on them. The mutual repulsion of the cement grains after the addition of the superplasticizer causes the grain agglomerates to break down and the water contained in them to be released. As a result, the liquidity of the concrete mix increases, facilitating its pumping, and the time of formation of cement hydration products is prolonged (delayed concrete setting time) due to the distance of cement grains from each other over considerable distances.

According to the PN-EN 934-2 standard, the CA40 FF Superplastyfikator as a fluidizing and plasticizing admixture can work in the construction industry in two ways. By using it, we can reduce the water/cement ratio (and thus reduce the consumption of mixing water by up to 25%) without compromising the consistency of the mix, which reduces the porosity of hardened concrete, which directly translates into a significant increase in its late strength (up to 30% compared to a mix without superplasticizer addition). The tightness of the concrete element is also improved, i.e. its resistance to aggressive substances, frost and abrasion resistance, as well as the adhesion of new concrete to the old one. Early strengths also increase, so demolding of the concrete element can be accelerated.

By reducing the amount of mixing water used, the addition of Superplasticizer CA40 FF and maintaining a constant water/cement ratio, we can reduce the amount of cement used, which, in addition to economic benefits, leads to a reduction in the heat of hydration and reduction of shrinkage during the setting of concrete. Thanks to the very low concentration of chlorides, the product does not contribute to the corrosion of steel reinforcements in concrete structures. It does not introduce large amounts of air into the concrete mix, which may potentially lead to deterioration of frost resistance. In addition, it allows you to make a concrete mix at an air temperature of up to -5°C without inhibiting cement hydration.

An important issue in the production of gypsum elements, e.g. drywall, is the reduction of the amount of water used in the process. The mechanism of action is analogous to the reduction of water in the concrete mix. The reduced amount of water, while obtaining the appropriate flow of the mixture, shortens the drying time of the board, and thus reduces the cost of its production. At the same time, Superplastyfikator CA40 FF does not affect setting times and adhesion between gypsum and paper. It favors the formation of gypsum crystals in the form of needles, thanks to which the structure of the board is more durable.

The use of even small amounts of Superplasticizer CA40 FF allows the production of cheap and environmentally friendly concrete, which at the same time is characterized by very good strength and rheological properties. It is recommended for the production of ready-mixed concrete, prefabricated elements, cement mortars and plasterboards.
