Sikament-320 IN
Standard High Range Water Reducing Superplasticizer for Concrete
Authorized Project Distributor — Sika India | Space Arc Engineering, Ghaziabad
Product Overview
Sikament-320 IN is a naphthalene-based high range water reducing (HRWR) superplasticizer admixture — one of the most widely used concrete admixtures in India. It dramatically reduces the water-cement ratio of concrete mixes while maintaining or improving workability and pumpability, thereby producing concrete with significantly higher strength and lower permeability than the equivalent water-only mix. Sikament-320 IN is typically added to the concrete mix at the batching plant or just before discharge, and is compatible with all types of Portland cement and most supplementary cementitious materials. It is the go-to admixture for RMC (ready-mix concrete) plants, precast element manufacturers, and civil infrastructure projects across India. Space Arc Engineering distributes Sikament-320 IN for concrete production and civil infrastructure projects across Delhi NCR and UP.
Applications
- Ready-mix concrete (RMC) plant production for improved pumpability
- High strength concrete for tall building foundations and columns
- Bridge deck concrete requiring low water-cement ratio
- Precast concrete element production for improved early demould strength
- Congested reinforcement zones where workability is critical
- Mass concrete where minimal water content reduces heat of hydration
Key Advantages
- Up to 20–25% water reduction at equivalent workability
- Significantly improves compressive strength and durability
- Enhances pumpability and flowability of concrete
- Chloride-free — no risk of steel corrosion
- Compatible with OPC, PPC, and blended cements
- Economical naphthalene-based HRWR suitable for standard applications

Frequently Asked Questions
What is the difference between Sikament-320 IN and Sika ViscoCrete products?
Sikament-320 IN is a naphthalene sulphonate (NSF) based HRWR superplasticizer offering good water reduction and workability. Sika ViscoCrete products are based on the more modern polycarboxylate ether (PCE) polymer technology, which offers superior water reduction, longer workability retention, and better compatibility with low water-cement ratio mixes. For most standard concrete applications Sikament-320 IN is adequate and economical; for high performance concrete or self-compacting concrete, ViscoCrete products are preferred.
Can Sikament-320 IN be used with fly ash or GGBS concrete?
Yes. Sikament-320 IN is compatible with concrete mixes containing fly ash (PFA) and GGBS as supplementary cementitious materials. In blended cement mixes, the dosage may need slight adjustment to achieve the target workability.
What is the maximum dosage of Sikament-320 IN?
The maximum recommended dosage is typically 1.5% by weight of cement. Exceeding this can lead to excessive retardation, set delay, or reduced long-term strength. Always trial-mix before committing to high dosages on production concrete.
