Sikament® S1

Sikament -S1 is 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.

Sikament® -S1 is 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.

Sikament® -S1 provides the following properties:
As a Super Plasticizer:
Workability is greatly improved. Increased place components with densely packed
reinforcement. Easy placing, less vibrating. Normal set without retardation.
Significantly reduces the risk of segregation. Improved water tightness.
As a Water Reducer:
Up to 20% water reduction. 16 hours compressive strengths increased by up to
100%. 28 days strengths improved by 40%.
Sikament® -S1 is chloride free-does not attack the reinforciment

Usage

Sikament® -S1 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 reinforcement.
. Textured surface finishes
It is also used as a water-reducing agent leading to high early strength concrete
such as:
. Precast concrete elements.
. Prestressed concrete.
. Bridges and cantilever structures.
. Concrete where formwork must be removed quickly or early loading applied.

Application Information

Compatibility

Sikament® -S1 is compatible with all types of Portland cement including S.R.C. and H.B.F. cements and may perform differently with variations in cement producers and cement chemical composition.
Accidental overdosing of Sikament® -S1 causes an extension of the initial setting time, however, no excessive amount of additional air will be entrained.

Dispensing

  • Sikament® -S1 can be added to the mixing water before addition to the aggregates or directly to the freshly mixed concrete (the plasticizing effect is more pronounced).
  • For Ready-mix concrete, Sikament® -S1 is added to the concrete immediately before discharge and after further mixing has taken place for three minutes.
Consumption

Recommended Dosage

0.6 – 2.8 % by weight of cement, depending on desired workability and strength, however, it is advisable to carry out trial mixes to establish the correct dosage rate required.
