Hi JB, If you mix it up and allow it to take a small set then add water again to consistence you will have about 15 to 20 min. Thanks DEJIA
QUIKRETE® does not recommend placements at 2” thick, as this geometry does not allow for stability and point impact resistance. The minimum recommended thickness is 3”. Each 80-pound bag of QUIKRETE® Concrete Mix will yield approximately 0.6 cubic feet when mixed. For a 30’ by 50’ pour at 3” thick, you will need 375 cubic feet of concrete, or 625 80-pound bags. Yields will vary with waste, uneven subgrade, etc.
Cold weather application refers to placement of concrete at ambient temperatures below the stated minimum of 50 degrees F. QUIKRET® 5000 Concrete Mix can be placed at temperatures below 50F by adapting cold-weather precautions, which include, but are not limited to, the following: store the raw materials in a warm temperature before use, use warm (not hot) water to mix, and ensure that the mortar is protected from freezing for at least 48 hours using plastic sheeting, insulated blankets, or other means. If these preventive measures cannot be taken, it would be best to wait for warmer weather.
QUIKRETE® 5000 Concrete Mix is suitable for all concrete applications requiring a high-early strength concrete designed to reach 5,000 psi once cured.
I believe it would work but only when you use the adhesive to bond the concrete together. I have not had much success with bonding concrete together but I was told that the concrete I was repairing was to old and I needed to replace entire slab
Presuming a 4” nominal post, the footer would be 12” by 12” and 42” long. At these dimensions, you will need 3.5 cubic feet of concrete. Each 50-pound bag of QUIRKETE® Fast-Setting Concrete Mix yields approximately 0.375 cubic feet, so you will need 10 50-pound bags. Yields will vary with waste, uneven subgrade, etc.
Please contact your local The Home Depot store for pricing and availability.
QUIKRETE® 5000 Concrete Mix is suitable for all concrete applications requiring a normal-setting product which will achieve 1500 psi after 24 hours and 5000 psi once cured. QUIKRETE® 5000 Concrete Mix will set in 4-6 hours after placement; if a faster setting time is desired, a Fast Setting product should be used.
QUIKRETE® Sand/Topping Mix (No.1103), in conjunction with QUIKRETE® Concrete Acrylic Fortifier (No.8610) replacing half of the required water content, is the combination of products recommended for a shower pan or a mortar bed for shower base or bathtub installation. ANSI 108.1 provides application and material requirements for shower pans and bathtubs. It is critical that the subfloor / structure underneath be rigid. Bathtubs require secure and adequate support because of the combined weight of the tub, person, and water. Please consult and follow local building /plumbing code requirements.
