Denka Pretascon Type 1

Compressive strength is 400 ksc (Cu) in 1 day and 800 ksc (Cu) in 28 days

Package 25 kg.

Introduction

The highest performance type of non-shrink grout cement, good flow ability with high early and high ultimate strength

Applications

• General concrete repair
  
• Concrete structure repair such as column, beam and road surface
  
• Cast the base for supporting column, bridge structure or concrete slab
  
• Fill the gap, such as foundation or concrete formwork
  
• Precast wall installation
  
• Work which is required greater strength than general concrete
  
• Work which is required early high strength
  
• Cast the base for supporting small to large machinery and with vibration such as generator, gas turbine etc.

Features

• Non-bleeding
  
• Controlled expansion / non-shrinkage
  
• Non-metallic, non-rusting and chloride free
  
• Good flow ability
  
• Non-air void
  
• High compressive strength
  
• High early and high ultimate strength. Compressive strength is 400 ksc (Cu) in 1 day and 800 ksc (Cu) in 28 days

Application procedure

• Surface preparation
  • In case of general grout, fill the joint between precast or cast the base for supporting machinery, it can be proceed the next step
  • In case of repair work, the existing concrete surface must be removed 1-2 cm. depth or deep until stone layer before continuing next step
• Clean concrete surfaces by using water or blowing air
  
• Install concrete formwork to be strong and without leakage
  
• Use water to keep concrete saturated at least 6 hours
  
• Before starting work, drain water out and blow the air for cleaning concrete surface
  
• Pour cement grout from one side to the other side by continuous pouring to prevent the void inside
