Sika Viscocrete HT-P-58PK | MCT CHEMICALS | SIKA PAKISTAN

Description
Sika® ViscoCrete®-HT-P-58 PK is a high-performance, water-reducing, slump-retaining, and superplasticizing admixture for concrete and mortar. Utilizing Sika’s advanced ‘ViscoCrete®’ polycarboxylate polymer technology (3rd generation), it offers multiple benefits for construction projects.

Key Benefits:

• Minimizes shrinkage during curing and reduces creep in hardened concrete
• Chloride-free, ensuring no corrosion risk for steel reinforcement
• Slows the rate of carbonation in concrete
• Vibration-free application, eliminating noise pollution
• Ideal for use in hot weather and improves pumpability with long-lasting consistency

Uses
Sika® ViscoCrete®-HT-P-58 PK is highly effective in the following applications:

• Piling applications, including Continuous Flight Auger (C.F.A.)
• Concrete containing supplementary materials like GGBS, microsilica, and fly ash
• Concrete exposed to hot, windy conditions or requiring extended workability and transportation
• Ready-mixed and high-performance concrete production
• Creation of impermeable, dense, and smooth-surfaced concrete for watertight applications
• Self-compacting concrete (SCC) production
• Manufacturing of complex and fine elements like slabs, foundations, beams, columns, and walls, even in areas with dense reinforcement

Certifications
Sika® ViscoCrete®-HT-P-58 PK complies with ASTM C-494, Type G.

Characteristics / Advantages
Sika® ViscoCrete®-HT-P-58 PK is an efficient superplasticizer that works through various mechanisms, such as surface adsorption and steric effects, to separate cement particles. The key advantages include:

• High water reduction, leading to denser, stronger, and less permeable concrete
• Excellent plasticizing effect, improving flow, placement, and compaction characteristics
