Superplasticizer SP-1 (similar to p-3)

Additive "Polyplast SP-1" is a mixture of sodium salts polietilentereftalat of different molecular weight. Supplement is available in two types: with not normalized by the entrainment and adding vastupidavusega component – reduced (normalized) with air entrainment (type VP). Additive "Polyplast SP-1" can be used in the manufacture monolithic and prefabricated reinforced concrete products and constructions of heavy, light and cellular concrete in the construction for different purposes: civil, industrial, transport, road, etc., including in the manufacture of products and designs of water supply systems. Additive "Polyplast SP 1" recommended for use in the manufacture of: • conventional concrete and prestressed structures from heavy concrete class B15-C40 and high-strength heavy concrete classes В45 and above; • structures made of lightweight concrete with porous aggregates classes 7.5 and higher; • the structures of fine-grained concrete class B10 and above; • if you want to use non-standard aggregates (fine Sands etc.); and also: • in the construction of monolithic structures using strain cement; • in the manufacture of monolithic and prefabricated structures of heat-resistant concrete for Portland cement, slag cement and alumina cement; • high-strength concrete produced from high-mobility and cast mixtures. The use of the additive "Polyplast SP-1" allows to achieve the following indicators: • to increase the mobility of the concrete mix from P1 to P5 without reducing the strength concrete; • to reduce the quantity of mixing water of 21% or more (in ravnopraviya mixtures); • to increase the ultimate strength characteristics of concrete by 20% or more (in ravnopraviya mixtures); • to reduce cement consumption by up to 22 % (in ravnopraviya mixtures) compared with the clear composition; • 1.5 – 1.6 fold increase in adhesion of the concrete with a bond fittings and the hardware; • to obtain concretes with high water resistance, frost resistance (in ravnopraviya mixtures); • to reduce time and energy costs for heat and humidity treatment concrete; • significantly reduce the time and energy cost of the vibrating the concrete mix, and in some cases completely abandon it; • increase the turnover of forms.
