KingGrout HT400®
High flow heat resistant cementitious precision grout.
Overview
KingGrout HT400 is a pre-mixed, pre-packed, high strength and heat resistant (up to 400°C) cementitious grout. It contains cement, selected additives, well graded, and non-reactive aggregate designed to give excellent flow properties, shrinkage compensation, and high compressive strength.
Applications
- KingGrout HT400 is ideally designed for grouting areas where high temperature resistance and high early strength grout is required
Advantages
- Non-shrink grout
- Suitable for use in hot areas
- Extremely dense and low permeability
- High early strength development allowing for rapid installation
- High flow, can be poured or pumped into variable gab widths down to 10 mm
- Easy to apply, single component which requires only addition of water
- Chloride free
- STANDARDS KingGrout HT400 complies with U.S. Corps of Engineers Specifications CRD–C588-79 and CRD – C621 in term of workability
- ASTM C1107, Grade A

| Under Base plate | Enough material should be available to achieve continuous fill and to complete the work. Pouring of the mixed grout should be started from one side only to avoid air entrapment. To obtain maximum flow distance, a side shutter feed between 100 mm to 250 mm high should be erected and used to build the required head. | — |
| Formwork | As the mixed grout possesses high fluidity characteristics, all formworks and shutters should be water tight. This can be obtained by sealing underneath the formwork and at the joints by using appropriate mastic. The unrestrained areas should be kept at a minimum due to the expansion nature of KingGrout HT400. | — |
