Lignosulphonate — Concrete Water Reducer & Set Retarder | GCC

CAS No: 8061-51-6 · HS Code: 3824.40

Lignosulphonates (sodium and calcium lignosulphonate) are natural by-products of the wood pulp industry, serving as first-generation water reducers and set retarders in concrete and construction applications. Cost-effective and biodegradable, lignosulphonates remain widely used in GCC concrete production — particularly for normal-grade concrete, precast concrete products, and applications where the combined water reduction and retardation effect suits the project requirements.

Applications — UAE, Saudi Arabia & GCC

Normal Water Reducing Admixture for GCC Concrete

Used at 0.2–0.3% by weight of cement to achieve 5–12% water reduction in standard structural concrete across GCC — improving workability without additional water addition.

Concrete Retardation in Hot GCC Weather

The combined water reduction + set retardation effect of lignosulphonates is valuable in GCC summer concreting — extending the workable period of fresh concrete during transit and placement in hot ambient conditions.

Concrete Block & Masonry Products

Used in zero-slump concrete block manufacturing to improve compaction and surface quality — cost-effective vs PNS or PCE for standard block production.

Compacted Earth & Soil Stabilisation

Lignosulphonates are used as dust suppressants and soil stabilisers in GCC construction access roads, temporary haul roads, and airfield sub-bases — the natural polymer binds soil particles and reduces dust generation.

Animal Feed Binder & Agricultural Use

Technical grade lignosulphonate used as a binder in feed pellets and as a slow-release soil conditioner in GCC agriculture — particularly date palm and greenhouse operations in Saudi Arabia and Oman.

Usage & Recommendations

Dosage: 0.15–0.30% by weight of cement. Above 0.5% causes excessive air entrainment and strength reduction. Lignosulphonate provides set retardation in addition to water reduction — account for this in mix design and production scheduling. For GCC high-performance concrete (C40+), PCE or PNS are preferred over lignosulphonate for higher water reduction without side effects. For standard C25–C35 concrete in normal GCC conditions, lignosulphonate is cost-effective. Contact Raykem for blend recommendations.

Frequently Asked Questions

Lignosulphonates and PCE are generally compatible but must be tested for your specific cement type and mix design. In some cases, lignosulphonate can reduce the effectiveness of PCE by competing for adsorption sites on cement particles. If compatibility issues occur (reduced slump retention, foaming), use them separately or contact Raykem for a pre-blended admixture combining the two actives in optimised ratios for GCC cements.
