KingGrout PC50®
Non-shrink cementitious grout for precast concrete units.
Overview
KingGrout PC50 is a non-shrink, chloride-free cementitious grout specially designed to fill the voids and gaps between the precast concrete elements. KingGrout PC50 consists of cement, selected well graded and non- reactive aggregates and special additives and designed to give excellent flow properties, shrinkage compensation, frost resistance, and high compressive strength.
Applications
- Filling the gaps and voids between precast concrete units
- Filling cracks, holes and groves in concrete substrates
- Filling of shutter tie rod openings
Advantages
- Shrinkage controlled mortar, reduces the risk of cracking due to shrinkage and ensure full contact with host concrete
- Easy to apply, single component, requires only addition of water
- Low permeability to water, providing excellent protection to steel reinforcements and host concrete
- Cost effective

PLACING AND FINISHING After mixing, the mortar is pumped into the joints and leveled with a steel trowel. If the joint is opened on the both sides, place a stopper board on one side of the joint. Remove the stopper board once sufficient amount of time has elapsed depending on the working conditions and use a trowel to finish the joint. The mortar can be applied using a normal screw pump. Pump the mortar carefully into the joints to ensure that the joint is thoroughly filled with the material and obtain a structurally functional joint. For the application behind reinforcement bars, a piece of steel tube with a pointed tip is attached to the hose to allow the ease of application. | ASTM D2369 |
