KingGrout GP80®
Non shrink cementitious precision grout.
Overview
KingGrout GP80 is a pre-mixed, pre-packed, high early strength, cementitious grout. KingGrout GP80 is compound of cement, selected additives, well graded fillers, and non-reactive aggregates designed to give excellent flow properties, shrinkage compensation, and high compressive strength.
Applications
- KingGrout GP80 is ideally designed for grouting areas beneath bridge bearing pads, heavy stanchion bases and base plates where high early strength grout is required
Advantages
- Non-shrink grout
- Suitable for use in hot areas
- Extremely dense and low permeability
- High initial and ultimate early strength development allowing for rapid installation
- Good flow, can be poured or pumped into variable gab widths down to 10 mm
- Easy to apply, single component, requires only addition of water
- Chloride free
- STANDARDS KingGrout GP80 complies with U.S. Corps of Engineers Specifications CRD –C588-79 and CRD – C 621 in term of workability
