Rapid Set® CEMENT ALL™ is a high-performance blend of Rapid Set Cement and specialty sand. When mixed with water, this product produces a high-quality repair material with rapid strength gain, high durability, and low shrinkage.
CEMENT ALL is durable in wet environments and can be used for general concrete repair, doweling and anchoring, industrial grouting, formed work, airport projects, and highway repair. It sets in just 15 minutes and is ready for normal traffic in one (1) hour.
CEMENT ALL is non-metallic and contains no added chlorides. It is similar in appearance to Portland cement repair materials and may be applied using similar methods.
Just one 55-pound bag of CEMENT ALL yields approximately 0.5 cubic feet.
Apply Cement All™ in thicknesses from feather edge to 4 inches. While CEMENT ALL will appear light gray, the final color may vary due to application techniques and environmental conditions.
Not intended for applications over 4” deep, for deeper sections use Rapid Set® Concrete Mix or Rapid Set® Mortar Mix. For overlay applications at least one test section should be prepared to evaluate the suitability of the materials and procedures.
For repairs, adjacent surfaces shall be clean, sound and free from any materials that may inhibit bond such as oil, asphalt, curing compounds, acids, dirt and loose debris. Roughen surfaces and remove all unsound concrete. Immediately prior to placement the repair surfaces shall be thoroughly saturated with no standing water.
The use of a power driven mechanical mixer, such as a mortar mixer or a drill mounted mixer, is recommended. Organize work so that all personnel and equipment are in place before mixing. Use clean Potable water. Rapid Set® Cement ALL™ may be mixed using 3 to 5 quarts of water per 55 lb. bag. Use less water to achieve higher strengths. Do NOT exceed 5 quarts of water per bag. For increased fluidity and workability use Rapid Set® FLOW CONTROL® plasticizing admixture from the Concrete Pharmacy®. Place the desired quantity of mix water into the mixing container. While the mixer is running add Rapid Set® Cement ALL™. Mix for the minimum amount of time required to achieve a lump-free, uniform consistency (usually 1 to 3 minutes). Do NOT re-temper.
Rapid Set® Cement ALL™ may be placed using traditional methods. Organize work so that all personnel and equipment are ready before placement. Place, consolidate and screed quickly to allow for maximum finishing time. Do NOT wait for bleed water, apply final finish as soon as possible. Rapid Set® Cement ALL™ may be troweled, floated or broom finished. On flat work Do NOT install in layers, install full depth sections and progress horizontally. Do NOT install on frozen surfaces. Use a method of consolidation that eliminates air voids. To extend working time use Rapid Set® SET CONTROL® set retarding admixture.
Water cure all Rapid Set® Cement ALL™ installations. Begin curing as soon as the surface has lost its moist sheen. Keep exposed surfaces wet for a minimum of 1 hour. When experiencing extended setting times, due to cold temperature or the use of retarder, longer cure times may be required. The objective of water curing shall be to maintain a continuously wet surface until the product has achieved sufficient strength.
Warm environmental and materials temperatures will reduce the working time of CEMENT ALL™. To compensate for warm temperatures, keep material cool and use chilled mix water. Temperatures below 70ºF (21ºC) will decrease the rate of strength gain and CEMENT ALL™ should not be applied if surface or ambient temperature is below 45ºF (7.2ºC).
