Overview

KingGrout HF200 is a cementitious, pre-mixed, pre- packed chloride and hydrogen free, high flow, pourable grout. It contains cement, selected additives, well graded and non- reactive aggregates and is designed to give excellent flow properties, shrinkage compensation, frost resistance, and high compressive strength.

Applications

KingGrout HF200 is ideally designed for use in the following applications:
Machine beds
Bridge bearing pads and plinths
Pile cap re-profiling
Under machinery base plates, crane rails, stanchion plates etc
Anchoring of tie bars, bolts, and stressing cables
Underpinning

Advantages

Non-shrink grout that has dual expansion properties to compensate for shrinkage in both the plastic and hardened stages
Extremely dense and low permeability
High early strength development allowing for rapid installation
High flow can be poured or pumped into variable gap widths down to 10 mm
Easy to apply, single component which require only addition of water
Hydrogen and chloride free
STANDARDS KingGrout HF200 complies with U.S. Corps of Engineers Specifications CRD–C621-82A and ASTM C1107, Grade C

Note	Typical properties @ 4.25 litre/25 kg @ 25°C. Compressive strength @ 1 day is under restrain. Compressive strength and Flexural strength @ 7 & 28 days are under wet cure @ 25⁰C. Depending on the consistency required, the addition of 3.5 litre (Trowellable) 4.25 litre (Flowable) or 4.45 litre (Fluid) of clean water should be added to a clean container. The 25 kg powder is then added slowly to the water while mixing continuously with a low speed mixer/ drill (400 - 600 rpm). Mixing should be continued for 3 minutes until a uniform consistency is obtained. THICKNESSES AND SIZE LIMITATIONS KingGrout HF200 can be applied in a single layer at thicknesses between 10 – 100 mm. For greater thicknesses, an 8 – 12 mm washed aggregate should be added at a ratio of 15 kg of washed aggregate to 25 kg of KingGrout HF200. PLACING AND FINISHING	—
Under Base plate	Enough material should be available to achieve a 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	KingGrout® HF200 High flow non-shrink cementitious precision grout. As the mixed grout poses high fluidity characteristics, all formwork and shutters should be water tight. This can be obtained by sealing underneath the formwork and at the joints by using an appropriate mastic. The unrestrained areas should be kept to a minimum due to the expansive nature of KingGrout HF200.	—
