Product Description
PCE 157L Slow-Release Superplasticizer

Redefine the Possible. Extend Your Workability.

The Industry's First True 6-10 Hour Slump Life.

Stop compromising on placement time. PCE 157L's breakthrough slow-release technology delivers unmatched control over concrete workability, empowering you to tackle the most logistically challenging projects with absolute confidence.

  • Ultra-Long Slump Retention (6-10 Hours)
  • Advanced Slow-Release Molecular Technology
  • Eliminates Cold Joints in Mass Pours
  • Ideal for Long-Haul & Hot Weather Concrete
  • Zero Chloride, High Durability
PCE Technology

Precision-Engineered Time Release Technology: Unlike conventional admixtures, PCE 157L's advanced polymer structure is designed to gradually disperse and interact with cement particles over many hours. This provides a steady, sustained release of water reduction power, not a rapid initial burst that quickly fades.

Workability Guarantee

Guarantee Performance: Forget about concrete turning unworkable on the truck. PCE 157L is your guarantee that the last cubic meter placed is as workable as the first, even after 6-10 hours of transit or complex placement procedures. Dramatically reduce rejection rates and wasted loads.

Mega Pours
Extreme Climates

Massive Pours & Demanding Climates: Execute flawlessly consolidated mega-pours without a single cold joint. PCE 157L is specifically engineered to defy high temperatures, maintaining performance even in environments exceeding 35°C (95°F).

Recommended Applications
  • Mass Concrete Pours: Dams, power plant foundations, large piers, raft slabs.
  • Ready-Mix with Extreme Haul Times: Remote mining sites, infrastructure in congested cities.
  • High-Performance Precast: Exceptionally large or complex architectural elements.
  • Critical Infrastructure: Where cold joints and imperfections are unacceptable.

CRITICAL COMPOUNDING INFO: PCE 157L is a specialized slump-retaining agent and must be compounded with a primary water-reducing PCE (e.g., PCE 154L, PCE 156L). It provides minimal initial water reduction on its own but extends the performance of the primary PCE exponentially.

Standard Compounding Ratio: Mass ratio of (PCE 154L / PCE 155L / PCE 156L) : PCE 157L = 82 : 5.5

FAQ
Q: How is PCE 157L different from PCE 155L? A: While both are slump retainers, PCE 155L is for "extended" retention (1-3 hours). PCE 157L is for "ultra-long" retention (6-10 hours) using specialized slow-release molecular technology.
Q: Does it delay the final set of concrete? A: It is designed to retard the loss of workability, not excessively delay the final set. The concrete will still gain strength on a predictable schedule.
Q: Can I use it in precast applications? A: Yes, it is excellent for extremely large or complex precast elements where long placement times are anticipated to ensure perfect consolidation.
Q: Is PCE 157L worth the investment? A: For logistically critical projects, the cost of a failed pour or cold joint far exceeds the investment. It is insurance for perfection in complex jobs.
Q: What is the recommended storage temperature? A: It should be stored in a cool, shaded place between 0°C and 40°C to maintain its chemical stability and shelf life.
Q: Is this product chloride-free? A: Yes, PCE 157L is completely chloride-free, making it safe for use in reinforced concrete structures without risk of steel corrosion.
