FLUENTIS® MM-330 concrete plasticizer is a specialized polycarboxylate ether (PCE) admixture from Parsman Chemical. It reduces mixing water and improves the workability of fresh concrete. Its formulation is suitable for mild and relatively warm temperatures. It also helps maintain the slump of ready-mix concrete during transport and before placement.
MM-330 concrete plasticizer improves the dispersion of cement particles, enabling the production of flowable concrete with less water. A properly controlled reduction in the water-to-cement ratio can increase compressive strength and reduce concrete permeability. This admixture is used in pumpable concrete, self-compacting concrete (SCC), and high-strength concrete. Maintaining workability also facilitates concrete placement.
MM-330 concrete plasticizer is a liquid, chloride-free admixture. Parsman Chemical lists ASTM C494 Type F and EN 934-2 in its technical data sheet. The product can also be used in concrete mixes containing silica fume. Before use, engineers should assess its compatibility with the cement and other mix constituents. Preliminary trials help control slump and achieve the desired performance.
Technical Note: Engineers should determine the dosage of MM-330 concrete plasticizer based on the target slump, cement type, concrete temperature, and transport time. Concrete mix trials help establish the appropriate dosage.

Compare concrete plasticizers FLUENTIS® MS-350, MM-330 and MW-310; select a grade for concrete temperature, transport time and workability retention
Concrete plasticizers FLUENTIS® MS-350, MM-330 and MW-310 from Parsman Chemical are based on polycarboxylate ether. These three grades reduce water demand at equal workability or increase flow at a fixed water-to-cement ratio, helping control fresh-concrete behaviour and improve hardened-concrete quality. Their main differences concern temperature suitability and slump retention.
All three datasheets list self-compacting concrete SCC, high-strength, pumpable, high-durability and high-performance concrete HPC and low-permeability concrete. For MS-350 and MM-330, mass concrete is also listed.
This grade is intended for summer concrete production and offers very high slump retention in very hot conditions. Maintaining workability in hot weather is central to its selection for ready-mix concrete and projects with considerable transport distances.
This grade is intended for transitional seasons and moderate to hot conditions, with high slump retention. For plant-produced concrete requiring flow retention during delivery, verify performance against the transport and discharge schedule.
This grade is designed for cold and moderate conditions, with suitable slump retention in these conditions. Its datasheet also highlights strength development in cold weather; confirm dosage and setting behaviour under actual project conditions.
The following table compares the specifications declared in the three datasheets. Density or pH differences alone do not indicate water-reducing capacity or final concrete strength.

Slump-retention descriptions are qualitative datasheet statements and do not establish an identical duration for all three grades. Numerical water reduction, slump-retention time and compressive strength require a valid test report for the specific grade and mix design.
| Product | ASTM reference | Shared references |
|---|---|---|
| MS-350 | ASTM C494 Type F & G | EN 934-2 Iranian National Standard 2930-2; Tables 3-1 and 3-2 |
| MM-330 | ASTM C494 Type F | |
| MW-310 | ASTM C494 Type F |
The datasheets also refer to concrete design for consistency classes, exposure conditions and durability according to EN 206. When submitting documentation to project supervision, review the grade-specific datasheet together with the test report and mix design.
The following ranges are declared for typical applications. Percentages refer to cement mass. Final dosage depends on cement type, materials, concrete temperature, target workability and required slump-retention time.
| Model | Percentage of cement mass | Quantity for 350 kg of cement |
|---|---|---|
| MS-350 | 0.3–1.5% | 1.05–5.25 kg |
| MM-330 | 0.20–1.5% | 0.70–5.25 kg |
| MW-310 | 0.2–1.5% | 0.70–5.25 kg |
The last column calculates the declared percentage range for an assumed cement quantity; it is not a separate dosage recommendation.
Admixture mass equals cement mass multiplied by dosage percentage, divided by 100. To convert kilograms to litres, divide mass by product density; the density of MW-310 differs from the other two grades.
All three datasheets advise against using dry aggregates without preparation. If aggregates are dry, premix them with part of the mixing water before the main mixing stage. Include this water and aggregate moisture in mix-design calculations.
Add the admixture with the water in the batching-plant mixer. When adding it to a truck mixer, provide at least 5 minutes of uniform mixing as specified in the datasheets.
Check initial workability, slump loss over the transport period, mixture stability and, where required, setting time and strength using actual project materials. Repeat evaluation after changes in cement, grading, temperature or admixture combination.
The datasheets state storage for at least one year in a dry place, in sealed original packaging, at 5–35 °C. Listed packaging includes 20-litre containers, 220-litre drums, and supply in 1,000-litre tanks or bulk tankers. Read the safety data sheet and packaging instructions before use.
To choose between MS-350, MM-330 and MW-310, first establish temperature conditions and transport time, then determine the dosage needed for target workability through trial mixes. Price per kilogram alone is not an adequate economic comparison; cost per cubic metre depends on the confirmed dosage.
