YCRO-SP-PC 500 is built on a special mixed design of melamine formaldehyde and polycarboxylic ether polymer with lengthy lateral chains, it differs from traditional superplasticizers. Cement dispersion is significantly enhanced by this. The ability of the cement particles to separate and scatter is compromised by the electrostatic dispersion that happens at the beginning of the mixing process. The water requirement of flowable concrete is significantly decreased by this technique. MYCRO-SP-PC500 combines workability retention and water reduction qualities. It makes it possible to produce concrete with high workability and/or high performance. With the help of this potent super-plasticizer, concrete with constant qualities around the necessary dosage can be produced.
MYCRO-SP-PC 500 are chemical additives that improve concrete's fluidity by reducing the amount of water needed. They are surfactants and they confer Negative Charge on individual Cement particles such that they are kept in a more Dispersed or Suspended state due to interparticle repulsion hence accounting for the Mobility of the particles. They work by reducing the surface tension between water and cement particles, which causes the particles to form a less open structure. This structure requires less water to fill spaces, which increases the strength of the concrete.
Where to use:
➢ Cold Weather Construction
➢ Precast Concrete Production
➢ Rapid Repair Work
➢ Airport Runways, Highways or Roads Applications
➢ Winter Sports Facilities
➢ High-Performance Concrete
➢ Emergency Repairs like after a natural disaster
➢ Thin Overlays and Toppings
Features of MYCRO- SP-PC 500 Superplasticizer Compounds:
➢ Improve workability: MSP-PC 500 allow for a reduced water-to-cement ratio
without sacrificing workability.
➢ Increase strength: It reduce the water-to-cement ratio, which increases the strength
of the concrete.
➢ Improve durability: It help produce concrete with a lower porosity, which makes it
more resistant to compression.
➢ Cohesion: Cohesion is improved due to dispersion of cement particles thus
minimizing segregation and improving surface finish.
➢ Improve surface finish: MSP-PC 500 help produce concrete with a better surface
finish.
➢ Improve adhesion: It help improve the bond strength and adhesion of concrete to
surfaces.
➢ Prevent cracking: It help prevent concrete from cracking.
➢ Produce self-consolidating concrete: It allow for the production of concrete that
flows and levels itself.
➢ Compatibility: It is compatible with other types of admixtures when added separately to the mix. Site trials should be carried out to optimize dosages. It is suitable for use with all types of ordinary Portland cements and cement replacement materials such as PFA, GGBFS and silica fume.
Method of Application
The optimum dosage is best determined by site trials with the concrete mix which enables the effects of workability, strength gain or cement reduction to be measured. Site trials with MSP-PC 500 should always be compared with mix containing no admixture. As a guide, a dosage range of 0.8 to 1.2 % weight of cement is normally recommended. An over dose of double the recommended amount of MSP-PC 500 will result in very high workability and may cause extension of initial and final setting times. However, the ultimate compressive strength will not be impaired.
Advantages
➢ Allow the production of high strength concrete without excessive cement contents
➢ Use in production of flowing concrete permits easier construction with quicker placing and
➢ compaction and reduced labour costs without increasing water content
➢ Chloride free, safe for use in prestress and reinforced concrete with increased strength
➢ Improved quality and improved cohesion properties
➢ Improved surface finish
➢ Improved cohesion and particle dispersion minimizes segregation and bleeding and
➢ improves pumpability
Precautions & Limitations
➢ Do not add MSP-PC 500 directly to dry cement & aggregate mix.
➢ Maintain water-cement ratio as low as possible.
➢ Do not increase the dosage of MSP-PC 500 than the recommendation.
Shelf Life
➢ Best before 2 years from the date manufacture when in sealed pack and stored under proper condition.
➢ Store in a cool & dry place. Health & Safety
➢ Use rubber hand gloves & safety goggles, while using MSP-PC 500
➢ In case of contact with skin, wash with plenty of water.
➢ Keep out of reach of children
