Superplasticizer effect deceleration setting "Polyplast SP-3"

Additive "Polyplast SP-3" is a mixture of sodium salts polietilentereftalat of different molecular weights of lignosulfonate technical, industrial mixture of thiosulfate and thiocyanate sodium. Supplement is available in two types: with not normalized by the entrainment and adding vastupidavusega component – reduced (normalized) with air entrainment (type VP). Preferred area of application of the additive "Polyplast SP-3" is preparation of ready-mixed concrete. Additive "Polyplast SP-3" can be used in the manufacture monolithic and prefabricated reinforced concrete structures from heavy, light and porous of concrete in construction for different purposes: civil, industrial, transport, road, etc.; including products and construction systems drinking water. Additive "Polyplast SP-3" is recommended: • the production of structures made of ordinary heavy concrete class B15-C40 and high strength heavy concrete classes В45 and above; • the production of structures made of lightweight concrete with porous aggregates class B7,5 and above; • the production of constructions of fine concrete class B10 and above; • if you want to use non-standard aggregates (fine sand and etc.); • in the construction of monolithic structures; • for high-strength concretes made from the highly mobile and cast mixtures. The use of the additive "Polyplast SP-3 allows to achieve the following indicators: • to increase the mobility of the concrete mix from P1 to P5 without reducing the strength; • 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); • 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; • to reduce time and energy costs for heat and humidity treatment concrete; • reduce the time and energy cost of vibrating the concrete mixture; • to increase the retention time of mobility of the concrete mixture in some brands of cement; • increase the turnover of forms.
