Quikrete’s Concrete Mix yield’s about . 15 cubic feet for every 20 pounds of mix, so a 40-pound bag yields .
QUIKRETE® Form & Pour Concrete Mix MS (1120-80 / NR810065) is designed to be used as a repair concrete in situations requiring a high quality concrete with a maximum aggregate size of 3/8 in (9.5 mm).
Thereof, How much quikrete do I need for a 10×10 slab?
For a 10 x 10 slab, you would need 77 60-pound bags or 60 80-pound bags. If we add an extra 10%, that’s an extra 8 60-pound bags or 6 80-pound bags.
Also to know is, Is quikrete as strong as concrete? Quikrete Fast-Setting Concrete Mix is easy to use — just add water — and it sets in 20 to 40 minutes. … That’s stronger than the concrete used for foundations on most homes.
Subsequently, question is, What happens if you put too much water in quikrete? When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size.
Also, How many square feet will one bag of quikrete cover?
Quikrete’s Concrete Mix yield’s about . 15 cubic feet for every 20 pounds of mix, so a 40-pound bag yields .
How long does quikrete concrete take to harden?
20 to 40 minutes
What happens if you put too much water in concrete?
When there is too much water in the concrete, there is greater shrinkage with the possibility for more cracks and reduced compressive strength. As a general rule, every additional inch of slump decreases strength by approximately 500 psi.
How much water do I need for an 80 lb bag of quikrete?
For each 80 lb (36.2 kg) bag of QUIKRETE Concrete Mix to be mixed, add approximately 6 pt (2.8 L) of fresh water to the mixer. Turn on the mixer and begin adding the concrete to the mixer. If the material becomes too difficult to mix, add additional water until a workable mix is obtained.
How many square feet does a 80lb bag of concrete cover?
4 sq feet
How many square feet does an 80lb bag of concrete cover?
4 sq feet
How much does a 12×12 concrete slab cost?
How much does a 12×12 concrete slab cost? The average cost to pour a 12×12 concrete slab that is 4” thick is between $888 and $1,584, with professional labor and materials included.
What is in Quikrete concrete mix?
QUIKRETE® Concrete Mix (No. 1101) is the original 4000 psi average compressive strength blend of portland cement, sand, and gravel or stone. Just add water.
How long does quikrete need to dry before rain?
Calcium chloride causes the concrete to harden, or set, within 30 minutes or less of adding water to the mix. It can then take up to 4 days to cure and harden to its maximum strength.
What happens if it rains on fresh concrete?
But after freshly mixed concrete has been placed, water in the form of a driving rain can do much more harm than good. Pouring concrete in the rain can compromise its strength, increasing the tendency for dusting and scaling to develop.
Will concrete dry if too wet?
When a concrete mixture is too wet, it causes a greater amount of shrinkage during the drying process than is needed. As a result, the concrete has a great likelihood of cracking and for those cracks are likely to be a fairly good size. … A watery mix actively reduces the compressive strength of the dried concrete.
Does water weaken concrete?
The rule of thumb: One gallon of water will increase the slump of 1 yard of concrete by approximately 1 inch. This should only be taken as a rule of thumb as there are various other conditions, like temperature and air content, that will change the water required to increase concrete slump.
How much water do you put in a 60 pound bag of quikrete?
about 1/2 gallon
