How many bags of concrete can a 3.5 cubic feet mixer?
I have a mixer that is advertised as being 3.5 cubic feet. My experience is that this mixer will handle up to two 60 pound bags or one and a half 80 bags at a time; anything more, and mix will spill out of the mixer when it is trying to mix the mix. 120 pounds of concrete mix makes about 0.9 cubic feet of concrete.
How much concrete can one person pour?
There isn’t a limit to how much can be poured, but there are specific requirements for pouring large volumes. Two problems can arise if the area of the placement is very large, and the depth is very deep. First, you must continuously pour concrete and do so in lifts so it can be consolidated as it is placed.
How many yards of concrete do I need for a 24×24 slab?
For example, for a concrete slab that is 24′ X 24′ X 4”, simply enter 4 in the Thickness/Depth field, 24 in the Width field, and 24 in the Length field. Click “Calculate”. Your answer should be 7.11 yards. Note: The Concrete Volume Calculator can also be used to determine yardage for aggregate products.
How many bags of concrete do I need for a 10×10 slab?
The thickness of your 10′ x 10′ slab will determine just how many bags you need. The average thickness of a 10′ x 10′ concrete slab for a shed is 4 inches thick. At 4″ thick, your 10 x 10 slab will take 56 bags of concrete that weigh 80 lbs.
How many wheelbarrows are in 1m3 of concrete?

How much concrete can you mix by hand in a day?
Mix by hand – where less than ¼m³ of concrete is needed, it can be mixed by hand by a reasonably fit person. Buying in Ready Mix – where more than 2m³ of concrete is needed, it is easier and probably cost effective to go for a delivery of ready mixed concrete.
Can we use concrete after 3 hours?
In order to control loss of workability and setting of concrete, the concrete should be delivered completely to the site of work within one and half hours (when the atmospheric temperature is above 200C) and within two hours ( when the atmospheric temperature is at or below 200C)of adding the mixing water to the dry Jun 10, 2014.
How long is concrete workable?
In standard industrial cases, full strength concrete is recognized at 28 days. At seven days, you should have concrete that is cured to 70% full strength or greater. But to answer the question of, “How long does concrete take to set?” concrete setting time is generally 24 to 48 hours.
What is the strongest concrete mix ratio?
Strong Concrete Mix Ratio In making concrete strong, these ingredients should usually be mixed in a ratio of 1:2:3:0.5 to achieve maximum strength. That is 1 part cement, 2 parts sand, 3 parts gravel, and 0.5 part water.
How much does it cost to pour a 20×20 concrete slab?
