Placement procedures are highly similar to Portland mixtures. No bleed water will develop with A300. Accordingly, finishing can be expedited if elevations and smoothness are achieved. No curing compounds are necessary and A300 can be cured in direct sunlight, the shade, or elevated temperature conditions. Like Portland mixtures, high wind conditions should be avoided and A300 should be protected from freezing for at least 48 hours dependent upon the mean daily temperature. If a glass-like finished surface is desired, placing plastic sheeting or film on the surface immediately after finishing and in-contact with the concrete for approximately 5 hours will achieve this effect. A300 may attain a blueish color, which is often mottled during curing. Some of this color will dissipate during the extended curing process. While finishing aids are not recommended, they can be used sparingly. We have developed a finishing aid under our product name Fusion Finish. Fusion Finish is supplied in 5-gallon buckets, or 270 gallon totes. Over applications of Fusion Finish will reduce the hardness and chemical resistance of the surface of the concrete, but will not affect the hardness or chemical resistance of the underlying mass. No aggregate segregation is expected up to an approximate 10-inch slump. Concrete consolidation with vibrators is highly similar to Portland mixtures. Over vibration should be avoided, particularly using high slump consistencies. Moving concrete with vibrators should be avoided. Concrete strength gain can be accelerated with A300 by applying heat in the form of ambient temperature, sunlight, or, applied heat by flame or other means.

Approximately 80-percent of design water mass should be batched into RMC delivery vehicles with mineral aggregate. Mineral aggregate mass and volume should be corrected based upon the measured moisture content, as compared to the design Saturated Surface Dry (SSD) condition. Cold Fusion Concrete materials are batched to design amounts and mixed at low speed revolutions for 2 to 3 minutes. Final water additions should be made to adjust the slump based upon quality control tests, and the RMC delivery vehicle should then be dispatched to the project.

The placement location requirements are no different for CFC® than for typical Portland Cement mixtures. The placement area should be moist, but no free water should be present. The placement area should be clean and free of debris. If bonding to existing CFC® or Portland materials, the exposed area should be thoroughly cleaned, moist but not wet, and roughened if possible (but not required). If bonding to existing CFC® or Portland, the interface should be vibrated to ensure complete and thorough contact with the new material. Ambient surface should not be freezing or above the boiling temperature of water. Elevated temperatures above 90’F will shorten the working time.
