FX-310 High Temperature Resistant Grout

DESCRIPTION:

FX-310 High Temperature Resistant Concrete is a pre-blended, high strength, heat resistant grout designed for industrial floors and surfaces. Its special characteristics are produced by the hard, dense, non-porous aggregates combined with cement. Both aggregates and cement allow FX-310 to withstand the toughest combinations of violent thermal cycling, continuous heat, severe abrasion, mechanical shock and corrosion that heavy industries demand.

ADVANTAGES:

Can be placed in areas of high erosion/heavy abrasion/cavitation
Excellent Corrosion Resistance - such as industrial wastewater, sulfates, diluted acids and alkalies (pH range of 3.5 to 11) and biogenic gas corrosion (pH * 2)
Can withstand thermal cycling (-160°F (-107°C) to +1800°F
Excellent abrasion and mechanical shocks resistant
Can withstand constant temperature soak at 1800°F
High Early Strength

TECHNICAL:

Abrasion Resistance - The abrasion resistance of FX-310 is unsurpassed by conventional concretes. FX-310 is a concrete with low porosity and high density, which results in 7 to 10 times more resistance to wear and tear than 5000 psi (34.47 MPa Portland Cement Concrete, and 2 times more abrasion-resistant than glass. The U.S. Army Corp of Engineers Test CRD-C-63-80, Test Method for Abrasion-Erosion Resistance of Concrete, was performed by an independent laboratory comparing FX-310 to ordinary Portland Cement Concrete with natural aggregates. The results show that FX-310 experienced only a 0.5% weight loss, while 5000 psi (34.47 MPa) Portland Cement Concrete experienced a 3.6% weight loss.

SURFACE PREPARATION:

For overlays, the substrate (generally Portland Cement Concrete) must be rough, clean, free from surface laitance.

MIXING:

It is important to note that water content is critical. Equipment used must always be clean and free from portland buildup to avoid flash setting. Use 0.5 (1.9L) to 0.5 (2.1L) gallons of water per 50 lb. bag (22.68 Kilo) of FX-310. Add 80% of the gauged water before introducing FX-310 in the drum. Add the remaining 20% after the first minute of mixing. Mixing time required is 3 to 5 minutes for the 50 lb (22.68 Kilo) bags.

FX-310 Concrete is placed using basic concreting practice. Pumping is not recommended because of FX-310's density and the aggregate's angular shapes. Slump is approximately 4" after mixing. Plastic or metallic joints (if used) should be set in place during casting. Vibrate the concrete as if it were Portland Cement Concrete. If the design calls for saw cut joints, saw just after the curing phase. Joints can be filled 4 to placement). Joint dimensions for each square should be 6'x 6' with depth of 1/3 of the slab.

WORKABILITY:

FX-310 provides a standard working time of 1 hour at 68°F (20°C) for the 50 lb. (22.68 Kilo) bags. This working time can easily be field-adjusted (retarded or accelerated) with appropriate FX admixtures to customers specifics. Once the initial set has occurred, mortars and concretes harden very rapidly.

CURING:

This important step determines the good surface aspect of FX-310 Concrete, just as it does for Portland Cement Concrete. Proper curing requires the avoidance of quick moisture loss during the first 6 critical hours after casting, especially in the case of mass concreting. If curing is not properly performed, surface cracking will appear in the initial hours, as well as excessive dusting. Curing should be implemented as soon as the surface hardens and begins to turn dry (no fingerprints can be left on the surface). The correct time is approximately 4 to 5 hours after mixing at 68°F (20°C) 1-1/2 hours for the 50 lb (22.68 Kilo) bags. When the temperature is warmer or the wind is blowing, curing must be applied immediately after finishing. Curing is accomplished using either several layers of liquid curing compounds, plastic sheets or water.

COLD WEATHER INSTALLATION:

Provided the fresh concrete is prevented from freezing until the heat evolution begins 1 hour for the 50 lb(22.68 Kilo) bags, curing temperatures can be as low as 0 F (-17.8 C) With recommended admixtures, the time to reach the exothermal reaction can vary from a few minutes to several hours.

LIMITATIONS:

FX-310 should be used at a minimum thickness depth of 1 inch. Do not surpass the recommended water quantities. Never add portland cement products. All steel must be a minimum of 2" from surface of hot face to withstand high temperatures.

WARRANTY:

FX-310 will meet or exceed the published specifications with a shelf life of at least 6 months in a controlled humidity storage.
