What is the wet unit weight of concrete?
unit weight= weight/volume.unit weight of normal concrete = 24 MPaIt is also known as density of concrete
What is the weight of plain cement concrete?
There are two different types of concrete; normal and lightweight. Normal concrete has a weight of 4,000 pounds per cubic yard, while lightweight concrete weighs 1,000 pounds per cubic yard less.
Concrete cure time?
In anarid region, concrete placed as a road slab or roof slab gets dried up in a very short time, say within 2 hours.This condition should be maintained for 24 hours or at least till the final setting time of cement at which duration the concrete will haveassumed the finalvolume.Normally curing is done for 28days at 90% of strength gain is achievedUntil maximum design strength is achieved (should be 28 days): Concrete does not gain strength by "Drying out". It gains it through a process known as hydration. The road slabs used as an example in the first post will still undergo hydration once water makes contact with the concrete. (rain). k.k
When should concrete forms be removed?
It depends. If the air and ground are warm, it might only be 2 or 3 hours before the forms are stripped. If a high-early-strength admixture is in the concrete mix, the forms could likely be remove at around an hour after placing it. This could result in stress cracks in the placed concrete, however. On the other hand, forms hold water inside the concrete where it is critically needed for the mix to cure and harden. If forms are stripped in the first 3 days or so since placing the concrete mix, then other means must be used to keep the water in the mix. A spray coat of latex liquid (Curing compound) can do it. A sprinkler running 24 hours per day can do it (This is the best way), or a covering of plastic sheeting can do it. Some people still use large burlap blankets soaked in water to cover the concrete.
What is the setting and hardening of cement?
Setting of cement is the initial solidifying of the cement. I presume you will not be using a cement material by itself, but by mixing in aggregates and fines to create 'concrete' I will continue this answer talking about concrete but much still applied to a simple cement mortar also. Depending on temperature (warm fast, cold slow) initial set will be between 2 and 24 hours. This will result in a concrete material that can easily be marked with a fingernail. Once the concrete has set, the concrete goes through a process called curing or 'hardening' where the pozzolanic constituents of the concrete 'hydrate' (react with the water) to create a hard material. This will continue for the life of the concrete but the most significant strength gains will be noticed within the first 28 days and this is the strength normally taken as the design strength of the concrete. It can be expected in ideal conditions with warm air and a light breeze in the air, for the concrete to achieve 30% of it's 28 day strength in 1 day 60-80% in 3 days 80-100% in 7 days and 100-% in 28 days Many factors will affect this. temperature will have a large impact. additives such as retarders and accelerators can be added to slow and speed up the hardening process respectively.
24 feet by 16 feet 4 inches thick how much concrete?
55
How thick is the 25 inches reinforced concrete pipe?
1/12th inside diameter plus 1 inch for 'B' wall (most common type), additionally, pipe sizes are normally in 1/4 or 1/2 foot increments, so the closest size would be a 24 inch diameter with 3 inch wall (24/12=2+1=3) having a outside barrel diameter thickness of 30 inches for 'A' wall 1/12th inside diameter, 'C' wall is 1/12th inside diameter plus 1 3/4 inch
What materials did they use to build Oak Island lighthouse?
The tower is built from monolithic reinforced concrete. The base is set upon 24 concrete filled steel pilings and are capped by a thirty foot wide by three foot deep octagonal concrete base on which the tower was built
What is the weight of 72 inches lenghty 24 inches diameter of the concrete block?
It is impossible to answer without knowing the density of the material that the pipe is made of and the strength of gravity at the location where the pipe is weighed.
How many yards of concrete do you need for a 12 x 24 4 inches thick?
12 x 24 x.33 = 95.04 cf /27 = 3.52 cubic yards
How many yards of concrete do you need for a 24' x 26' 4 inches thick?
for ,this we need to calculate the volume of concrete . volume of concrete = L x B Xh. =17 X 4 X24 . =1632 inch cube. Thus,1632 cubic inches concrete is needed for 17 inch by 24 inch by 4 inch deep .
How many yards of concrete would it take to cover a 24 ft x 40 ft x 12 inches thick?
24 x 40 x 12in = 24ft x 40ft x 1ft = Volume = 24 * 40 * 1 = 960ft³ = 9.865yd³
How many yards of concrete is used in a side walk 32 feet long 3feet wide 3inches thick?
Cubic feet of concrete required = 32 x 3 x 0.25 = 24 cu. ft 1 cu yd = 27 cu ft Answer: 24/27 cu yards = 0.89 cu yards.
What is the equivalent pipe size for two 15 pipes?
24 inch pipe.
