DrucPlast SA (SNF Based Concrete Admixture)

Description

Drucplast SA is a conventional concrete admixture based on a blend of sulphonated naphthalene formaldehyde condensates  and  other  specially   selected   organic   polymers.   Its   combined   super   plasticizing  properties gives it significant water reduction at any given workability. It can be used as an ASTM  type  F  &  A,  depending upon the dosage used. It produces very cohesive concrete with good fluidity and moderate slump retention.

Fields of Application :-

 Produces low- to medium-grade pump-able concrete with moderate dosage.

Can be used with slightly higher dosages in high-grade concrete where both early and later strength gain is required.

Can be used in shotcrete where quick setting is desirable.

Key Features :-

 Easy  to   use   –   Low   water   content   results   in cohesive concrete, easier and quicker placement and compaction, and a better surface finish.

High  early  and   final   strength   –   Low   water-to- cement ratio improves  strength  while  maintaining  the same workability.

Increased   concrete   durability             Lower  W/C  ratio   and   cement   paste   content   results   in high impermeability, low susceptibility to chemical attack and reduced shrinkage cracks.

Faster jobs The product initiates early setting and strength gain.

Cost effective The product reduces the use of cement by approximately 10-20%.

Conforms To International Standards :-

 This quality product conforms to the following standards:

ISO: 9103-1999, (reaffirmed 2004)

Edition 2.2 (2007-2008) ASTM C494/C494M-08a

Type F & A, & BS EN 934

High Compatibility :-

 The product is compatible with all cement types, except for high alumina  cement.  It is  also  compatible with fly ash and other GCPL admixtures.

Technical Properties :

Chemical basisSulphonated Nephthalene Formaldehyde Condensate
Specific gravity1.20 ± 0.02 at 20°C
Chloride ContentNIL (BS EN 934)
Air entrainmentMay increase marginally/less than 1 % additional air is entrained within

the recommended dosage

Effect on setting timeVery nominal at normal dosages. Higher dosages may show over

retardation

Dosage :-

Optimum dosage should  be  determined  by  site  trial  with  the  desired  concrete  mix.  Avoid  overdosing.  The  rate of addition is usually 0.8% to 1.5% by wt. of cement, depending upon the required water reduction, slump retention and strength gain.

Directions for use :-

Drucplast SA is supplied ready for use. For maximum dispersion  throughout  the mix,  refer  to  the chart  below.  Mix the indicated quantity of Drucplast SA and water to pre wet  cement  aggregate  mixture.  Allow the mix to  rotate for at least three minutes. Do not add to dry cement under any circumstances.
