HM-530 concrete hyperplasticizer is a high-range water-reducing admixture from Parsman Chemical’s FLUENTIS® range. Based on polycarboxylate ether (PCE), it is formulated for ready-mixed concrete production during transitional seasons. It also helps retain slump in hot weather and maintain workability during long-distance transport.
HM-530 concrete hyperplasticizer reduces mixing water while maintaining the same workability. With an appropriate mix design, lowering the water-to-cement ratio can increase compressive strength and improve resistance to the ingress of water, dissolved chemicals and carbon dioxide.
At a constant water-to-cement ratio, the admixture improves flowability, which helps produce self-compacting concrete. An optimized mix design can also reduce both water and cement content while maintaining flowability. This can help reduce drying shrinkage and heat of hydration.
HM-530 concrete hyperplasticizer is a colorless to amber liquid with no chloride content. The datasheet lists compatibility with reactive silica fume, R200 retarding admixture, expansive agents, air-entraining agents and shrinkage-reducing admixtures.
The recommended dosage for typical applications is 0.10–0.8% by weight of cement. Add the admixture to the plant mixer at the same time as the mixing water. If adding it directly to a truck mixer, mix the concrete for at least 5 minutes to distribute the admixture evenly.
For best results, use water-saturated aggregates. If the aggregates are dry, premix them with part of the mixing water. Use trial mixes to determine the dosage for the target slump, cement type, concrete temperature and transport time.

Compare FLUENTIS® HW-510, HM-530, HS-550 and HS-550B for cold, transitional and hot conditions using the individual product datasheets.
All four FLUENTIS grades are based on polycarboxylate ether. The polymer side chains help keep cement particles dispersed. This allows either a reduction in mixing water at equal workability or an increase in workability at a constant water-to-cement ratio. Define the test objective before comparing grades.
For ready-mixed concrete in cold seasons and projects that require faster hardening. The datasheet refers to transport for one hour or more without loss of workability in cold climates. Verify this period using the project's concrete temperature, cement and actual discharge time.
Introduced for ready-mixed concrete in transitional seasons. The datasheet refers to slump retention in warm conditions and over substantial transport distances. Assess slump loss up to discharge and mix stability during pumping.
A summer-grade hyperplasticizer with high slump retention at elevated temperatures and during long hauls. Measure slump loss over time at a concrete temperature representative of site conditions and assess setting time when selecting the dosage.
Introduced for ready-mixed concrete in hot weather and during long hauls, with very high slump retention. The datasheet specifies an amber colour and 40 ± 1% solids. Use the effective dosage from trial batches to compare costs per cubic metre.
Common listed applications include self-compacting, pumpable, high-strength, high-performance and high-durability concrete. Mass concrete is listed for HM-530, HS-550 and HS-550B. Low-permeability concrete is explicitly listed for HW-510, HM-530 and HS-550.

The values come from the supplied datasheets. Only HS-550B has a stated solids content. Solids content alone does not establish the active polymer content or provide a basis for direct dosage conversion between grades.
The application notes also refer to EN 206 for consistency classes, exposure conditions and durability requirements. For project approval, check the datasheet edition, grade-specific test report and trial mix results against the contractual acceptance criteria.
| Grade | Recommended range | Basis stated in the datasheet |
|---|---|---|
| HW-510 | 0.10–0.80% | Volume-to-weight (v/w), based on cement weight |
| HM-530 | 0.10–0.80% | Percentage by weight of cement |
| HS-550 | 0.15–1.00% | Percentage by weight of cement |
| HS-550B | 0.10–1.00% | Percentage by weight of cement |
The English HW-510 datasheet uses a volume-to-weight basis (v/w). Confirm the calculation basis and dosing equipment units before setting the dosage. For a mass-based dosage, multiply the cement mass by the dosage percentage and divide by 100 to obtain the admixture mass in kilograms. To set a pump in litres, divide the admixture mass by its density in kilograms per litre.
If aggregates are dry, pre-mix them with part of the mixing water as directed in the datasheets. Add the admixture to the mixer with the mixing water. The HM-530, HS-550 and HS-550B datasheets specify at least five minutes of uniform mixing when the admixture is added in a truck mixer.
The datasheets list reactive silica fume, air-entraining admixtures, expansive agents and shrinkage-reducing admixtures. The HW-510 datasheet refers to AX100 accelerator for cold conditions. The HM-530, HS-550 and HS-550B datasheets refer to R200 retarder for very hot conditions or very long hauls. Verify dosage, addition sequence and the combined effects on setting and workability in trial mixes.
The datasheets list 20-litre containers, 220-litre drums, and 1,000-litre IBC or bulk supply by arrangement. The minimum stated shelf life is one year when stored dry in the original sealed packaging at 5–35 °C. Read the safety data sheet and packaging instructions before use.

Request Technical Advice and a QuotationWhen choosing a concrete hyperplasticizer, consider both the required water reduction and how long the fresh concrete needs to remain workable before discharge and placement. Parsman Chemical’s FLUENTIS® hyperplasticizers are based on polycarboxylate ether (PCE) and are designed to reduce mixing water while helping achieve the required workability. The four grades address different temperature conditions and slump retention needs during transport.
To select the right grade and dosage, consider the cement type, concrete temperature, transport time and target slump at discharge. Confirm the admixture’s performance with a trial mix using the project materials. For technical advice and a quotation, contact Parsman Chemical’s technical team.
