GreatWhite120™ is an extremely versatile, cementitious, rapid setting, semi-leveling structural repair concrete. It is a single component powder that is water activated. GreatWhite120™ has 20 minutes of working time and will reach compressive strengths of more than 2,500 psi within 2 hours from the addition of water. GreatWhite120™ can be applied in ambient temperature ranges from 30 to 120 degrees Fahrenheit. GreatWhite120™ finishes like traditional Portland based concrete and cleans up easily with water. GreatWhite120™ rapid, large area concrete has been designed for use with volumetric concrete mixers for large scale repair projects.

Recommended Uses
GreatWhite120™ has been designed for horizontal, sloped and vertical applications providing for rapid return to service of 2 hours for roads and bridge decks, aviation runways, parking garages, piers, columns, foundations, parking lots, marine access ramps and any other repair or new construction application application where rapid early strength gains are required.

Technical Data
Results provided by licensed engineering test laboratory and represent typical results from production materials. Actual results may vary from third party testing results; however, CERATECH’s materials meet and/or exceed established internal quality control standards, (available upon request) . All samples were air cured.

Site Preparation
Surfaces should be prepared in accordance with ICRI 03730, “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.” and / or ACI 546R-96 “ Concrete Repair Guide” Concrete surface should be prepared by appropriate mechanical methods to obtain an exposed aggregate surface with a minimum surface profile of +/- 1/16” (1.5 mm) in accordance with ICRI 03732. Pre-existing coatings or surface treatments should be completely removed. Dry, clean, stable surfaces are required. Remove all standing water. Reinforcing steel should have no loose scale.

Application and Finish

• Surfaces of host concrete must be damp with no standing water.
• Working times based on ambient temperature, types of aggregate and total amount of water. Working times are also influenced by surface temperature, humidity and repair profile.
• Minimum profile thickness is 1.50” (3.8 cm) when using 0.50” (1.3 cm) aggregate or 3.00”(7.6 cm) when using 1.00” (2.5 cm) aggregate. There are no restrictions to the depth of the repair profile.
• Upon initial set, a broom finish can be applied. Upon final set, the material can be saw-cut, drilled, sanded and/or polished.
• Do not re-temper. The addition of water to the surface of the repair will negatively affect the materials final properties.
• General loading in 2 hours for wheeled traffic and 1 hours for foot traffic after addition of water. In ambient and/or surface temperatures below 32°F/0°C, extend the loading time by 60 minutes for each 10° below 32°F/0°C.
• All previously existing joints must be re-established within 1-2 hours of final set.
• Self-curing, (Protect with blankets or equivalent in ambient temperatures below 32°F / 0°F).
• Clean all tools and equipment with water prior to the material reaching final set.

• See Material Safety Data Sheet (MSDS).
• This document does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this document to establish appropriate safety and health practices and to determine the applicability of regulatory limitations prior to use.
• Dispose of water materials in accordance with Federal, State, and Local regulations.
