4-SeCcturl StrCth inR24rTs /E6000 MPSI inX8 Days PRODUCT DATASHEET DESCRIPTION: CTS 24/6 CONCRETE MIX is a high-performance, multi-purpose, concrete for use where fast strength gain and high ultimate strength are desired. Durable in wet environments, 24/6 CONCRETE MIX is a blend of portland cement, high-performance additives, and quality aggregates. 24/6 CONCRETE MIX is ready for foot traffic in 8-10 hours and reaches structural strength in 24 hours. USES: Use 24/6 CONCRETE MIX for general and structural concrete repair, setting posts, driveways, walkways, floors, sidewalks, patios, formed work, footings, and more. APPLICATION: Apply 24/6 CONCRETE MIX in thicknesses from 2"to 24" (5 cm to 61 cm) . Forthinner sections, use Rapid Set® Cement All® or Rapid Set® Mortar Mix. SURFACE PREPARATION: For repairs, application surface must be clean, sound and free from any materials that may inhibit bond, such as oil, asphalt, curing compound, acid, dirt and loose debris. Roughen surface and remove all unsound material. Apply 24/6 CONCRETE MIX to a thoroughly saturated surface with no standing water. MIXING: Use 2.25 to 3 quarts (2.1 to 2.8 L) of clean, potable water per 60-lb (27.2-kg) bag. Use less water to achieve higher strengths. Do not exceed 3 quarts (2.8 L) of water per bag. Do not add any additional additives. Mechanical Mixing – The use of a mortar mixer, concrete mixer, or a drill-mounted mixer is recommended. Place the desired quantity of mix water into the mixing container. While the mixer is running, add 24/6 CONCRETE MIX. Mix for the minimum amount of time required to achieve a lump-free, uniform consistency (usually 1 to 3 minutes) . Let mixture stand 1-2 minutes; mix again until desired consistency is achieved. Hand Mixing– Place the desired quantity of mix water into the mixing container. Add 24/6 CONCRETE MIX and mix using a shovel or hoe. Turn and fold the mix until a lumpfree, uniform consistency is achieved. Let mixture stand 1-2 minutes; mix again until desired consistency is achieved. PLACEMENT: Organize work so that all personnel and equipment are ready before placement. Use a method of consolidation that eliminates air voids. Place, consolidate and screed quickly. 24/6 has a working time of roughly 1 hour. 24/6 CONCRETE MIX may be troweled, floated or broom finished. On flatwork, do not install in layers. Install full-depth sections and progress horizontally. For every 6' to 8' (1 .83 m to 2.44 m), cut a control joint with depth equal to one-third of the slab thickness. Do not install on frozen surfaces. 24/6 CONCRETE MIX may be applied in temperatures ranging from 45°F to 90°F (7°C to 32°C) . CURING: Water cure all 24/6 CONCRETE MIX installations by keeping exposed surfaces wet for a minimum of 3 days using common curing methods. Begin curing after finishing the surface. Alternatively, a curing compound may be used in accordance with manufacturer’s instructions. When experiencing extended setting time due to cold temperature, longer curing times may be required. COLD WEATHER: Environmental and material temperatures below 70°F (21°C) may delay setting time and reduce the rate of strength gain. Lower temperatures will have a more pronounced effect. Thinner sections will be more significantly affected.

FAQs

How fast does CTS 24/6 CONCRETE MIX reach foot traffic and structural strength?

Foot traffic is possible in 8-10 hours, and structural strength is reached in 24 hours.

What are the required mix water limits per 60-lb bag?

Use 2.25 to 3 quarts (2.1 to 2.8 L) of clean potable water per 60-lb (27.2-kg) bag, and do not exceed 3 quarts (2.8 L).

What curing method is recommended after finishing?

Water cure by keeping exposed surfaces wet for at least 3 days, starting after finishing; curing compounds may be used per manufacturer instructions.
