Cur síos
BDH is a naphthalene-based highly effective water reducing agent for promoting accelerated early and ultimate strength development, commonly referred to as a superplasticizer, also named Naphthalene Sulfonate Formaldehyde Condensate ), SNF, PNS and FDN etc.
Buntáistí
Feabhas suntasach ar inoibritheacht gan uisce méadaithe nó baol deighilte. Gnáththacar gan mhoilliú, fiú nuair a dhéantar ródháileog. Dlús feabhsaithe agus bailchríoch dromchla.
High water reducing rate. High strengths after 8 hours.
Ag luí le stroighin Portland, stroighin Gnáth Portland, Stroighne Slag Portland, Stroighne Flyash, Stroighne Pozzolanic Portland, etc.
Feabhas a chur ar inoibritheacht (titim) coincréit nuair a chuirtear isteach sa trucail mheasctha é.

Dosage
0.5 - 1.5 percent by weight of cement. Exact dosage rates are dependent on the type of effect sought, quality of cement and aggregates, water/cement ratio and ambient temperature. Therefore, in many cases it is advisable to carry out trial mixes.
JK-02NP can be added directly or added in after dissolved in water. It can be added during mixing and after-mixing (better). The after-mixing approach can achieve better result.
Package, Storage Shelf Life
