FUTURA®-45 EXTENDED
RAPID-SETTING CONCRETE
DESCRIPTION
FUTURA-45 EXTENDED is a one-component, shrinkage compensated, proprietary blend of cements, aggregates, and performance-enhancing chemical additives. This rapid setting concrete is mixed with water on site and used for large-scale horizontal concrete repairs and form and pour vertical applications that require high early-strength gain.
USES
FUTURA-45 EXTENDED is ideal for interior and exterior horizontal concrete surfaces, such as airport runways, concrete slab replacement, bridge repair, and parking decks.

SURFACE PREPARATION
Perform surface preparation in accordance with ICRI technical guidelines. Concrete must be sound and fully cured (28 days). Saw cut the perimeter of the area being patched into a square with a minimum depth of 1/2″ (13 mm). Remove all unsound concrete and roughen the surface to a minimum 1/4″ profile amplitude. Remove all laitance, oil, grease, curing compounds, and other contaminants that could prevent adequate bond. The concrete substrate should be saturated surface dry (SSD), without standing water, before application. Apply the mixed material onto the prepared SSD substrate by trowel or screed. Ensure proper consolidation of the mortar and compaction around reinforcing steel. Minimum application thickness is 1″ based on a 3/8″ maximum coarse aggregate. Finish the completed repair, as required, taking care not to overwork the surface.
Reinforcing Steel … Remove all oxidation and scale from the exposed reinforcing steel in accordance with ICRI Technical Guideline No. 03730 “Guide for Surface Preparation for the Repair of Deteriorated Concrete Resulting from Reinforcing Steel Corrosion.”
MIXING
Mix with 5 – 5.5 pints (.65 gal.) of potable water per 70 lb. bag. Conduct field trials to verify proper slump (approx. 8″), yield, and a thoroughly mixed product.
CURING
Cure immediately after finishing. Use a curing compound that complies with ASTM C 309. In extreme heat, keep the patches covered and damp.
CLEANUP
Clean tools and equipment with clean water immediately after use. Cured material must be removed mechanically.
PRECAUTIONS
Read and follow application information and use in accordance with the health and safety information shown on the label. Refer to Material Safety Data Sheet for complete health and safety information.
