- Ready-to-Use Product Features
- Advantages
- ISOLA PSM produces low water-cement ratio concrete and consequently high strengths.
- ISOLA PSM produces flowing, self-leveling concrete with better than normal strengths.
- ISOLA PSM will produce waterproof concrete due to water-cement ratio attainable in the range of less than 0.4
- ISOLA PSM will reduce cement content substantially without workability or strength loss.
- ISOLA PSM aids in concrete placement and consequently reduced labor cost and faster completion time of construction.
- ISOLA PSM reduces segregation and bleeding in plastic concrete.
Applications & Uses

- Application
ISOLA PSM is used to:
- Used in concrete of all classes -readymix, prestressed, precast, shotcrete, etc.
- Increase workability – highly fluid, self leveling pumpable concrete can be attained when added to a 50-75 mmslump. The increased fluidity is ideal for use in heavily reinforced sections requiring little or no vibration. Theincrease in slump do not lower the potential concrete strength.
- Reduce water content-25-30% water reduction can be attained while maintaining the same slump. This will result in a reduced cement if the objective is to maintain a fix water cement ratio without loss in strength. The water reduction will also result in a dense, water-impermeable concrete mass.
- Accelerate Strength- without reducing cement content, 70% of specified 28 days strength can be obtained after 24 hours, when used as a high range water reducer.
To prevent rapid loss of workability at ambient temperatures in excess of 32 degree C or windy weather, apply theprecautionary methods detailed in ACI 305 R-77 "Hot Weather Concreting".
- Dosage
- Depending on mix design requirement, ISOLA PSM can be added at the rate of 0.30-1 liter PER 50 Kg. bag cement (0.6-2.0 liters per 100 Kg.). When designing mixes for use with ISOLA PSM, it is recommended to make trial batchesto determine optimum dosage. As a guide for designing mixes, ACI 211.1 or 211.2 recommendations should befollowed. ISOLA PSM is also compatible with ISOPLAS BT water-reducing, retarding admixture.
- Overdosing - An overdosing of the recommended amount of ISOLA PSM may result in set retardation but it has been known that final properties will not be affected as long as the concrete is placed, consolidated, and cured properly in accordancewith generally accepted concreting practice such as those recommended in ACI.
- Addition
ISOLA PSM can be added at the batch plant or at the site. However, the latter method of addition will result in morelonger workability and placement time. For central mix type operations, approximately 80% of the total amount mixingwater is added to the dry ingredients. Mix for 30 seconds then add ISOLA PSM simultaneously with the remaining20% mixing water. For 1 cubic meter batch, total mixing time from the time cement comes in contact with water should not be less than 100 seconds.
