Sikament-NN Price In Bangladesh

Description

Product Description   :

A highly effective dual action liquid super-plasticizer for the production of free
flowing concrete or as a substantial water-reducing agent for promoting high early
and ultimate strengths.
It complies with ASTM C494 Type F and BS 5075 Part 3.

Uses Sikament®
-NN is used as a super plasticizer in the production of free flowing
concrete such as:
 Slabs and foundations
 Walls, columns and piers
 Slender components with densely packed reinforcements
 Textured surface finishes
It is also used as water-reducing agent leading to high early strength concrete such
as:
 Pre-cast concrete elements
 Pre-stressed concrete
 Bridges and cantilever structures
 Concrete where formwork must be removed quickly or early loading applied.

Advantages Sikament®
-NN provides the following properties:
As a super plasticizer:
 Workability is greatly improved.
 Increased place ability in slender components with dense reinforcement.
 Easy placing, less vibrating.
 Normal set without retardation.
 Significantly reduces the risk of segregation
As a water Reducer:
 Up to 20% water reduction.
 16 hour compressive strengths increased by up to 100%.
 28 day strengths improved by 40%
 Increased water tightness.
Chlorides free.

Application
Dosage 0.6 – 3 % by weight of cement, depending on desired workability and strength.
Dispensing Sikament®
-NN can be added to the mixing water prior to its addition to the
aggregates or directly to the freshly mixed concrete, where the plasticizing effect is
more pronounced.
For Ready-mix concrete, Sikament®
-NN is added to the concrete immediately prior
to discharge and after further mixing has taken place for three minutes.
