How many yards of cement do you need for a 1400 x 3 slab?
The question does not provide units of measure which are important in answering the question. However, it is likely that the slab is 1400 square feet and that the slab thickness is 3 inches. A cubic yard of concrete is 3 ft by 3 ft by 3 ft, or 27 cubic feet. To solve the problem, you convert the slab size into cubic feet by multiplying the length in feet by the width in feet (to get 1400 square feet) by the thickness of the slab in inches divided by 12 inches per foot or 1400 * 3 / 12 = 350 cubic feet. To convert to cubic yards, divide the 350 cubic feet by 27 cubic ft/cubic yard to get 12.96 cubic yards. So, order 13 yards of concrete.
What is the chemical composition of reinforcing steel bar?
Steel has an expansion coefficient nearly equal to that of modern concrete. If this weren't so, it would cause problems through additional longitudinal and perpendicular stresses at temperatures different than the temperature of the setting.[2] Although rebar has ribs that bind it mechanically to the concrete, it can still be pulled out of the concrete under high stresses, an occurrence that often precedes a larger-scale collapse of the structure. To prevent such a failure, rebar is either deeply embedded into adjacent structural members (40-60 times the diameter), or bent and hooked at the ends to lock it around the concrete and other rebar. This first approach increases the friction locking the bar into place, while the second makes use of the high compressive strength of concrete. Common rebar is made of unfinished tempered steel, making it susceptible to rusting. Normally the concrete cover is able to provide a pH value higher than 12 avoiding the corrosion reaction. Too little concrete cover can compromise this guard through carbonation from the surface. Too much concrete cover can cause bigger crack widths which also compromises the local guard. As rust takes up greater volume than the steel from which it was formed, it causes severe internal pressure on the surrounding concrete, leading to cracking, spalling, and ultimately, structural failure. This is a particular problem where the concrete is exposed to salt water, as in bridges built in areas where salt is applied to roadways in winter, or in marine applications. Epoxy-coated, galvanized or stainless steel rebars may be employed in these situations at greater initial expense, but significantly lower expense over the service life of the project. Especially epoxy-coated have to be installed with great care, because even small cracks and failures in the coating can lead to intensified local chemical reactions not visible at the surface. Fiber-reinforced polymer rebar is now also being used in high-corrosion environments. It is available in many forms, from spirals for reinforcing columns, to the common rod, to meshes and many other forms. Most commercially available rebars are made from unidirectional glassfibre reinforced thermoset resins. visit the web to more about Reinforcement bar http://en.wikipedia.org/wiki/Rebar

How much rebar do you need for 10 x 15 slab?
If your peice of concrete does not have beams I consider that flatwork. So in flatwork with 3/8 rebar (#3) on 16" centers, for the 15 foot side you will have 8 pieces x 15' long. On the 10' side you will need 12 pieces x 10'. (6 bars cut in half) In all you will need 14 #3 x 20'
How much concrete to pour a 12ft by 12ft slab?
12 x 12 feet, 4 inches deep: 1.8 cubic yards, minimum.
How much does 1 ft of 4 rebar weigh?
12" of #4 rebar = 0.668 lb/ft

How many yards of concrete would you need to pour a 12 x 12 slab 4 thick?
1.78 cu. yds.
How much concrete would it take to pour a 12 foot by 12 foot 2 inch slab?
12-ft x 12-ft x 2-in = 24 cubic feet = 8/9 of 1 cubic yard

How much concrete you need for slab 12ft by 10ft by 4 inches thick?
12 ft x 10 ft x .333 ft (4 in) = 39.96 cu ft. You need enough concrete for 40 cubic ft.
How much concrete you need for slab 12ft by 10ft by 4 inches thick.?
12 ft x 10 ft x .333 ft (4 in) = 39.96 cu ft. You need enough concrete for 40 cubic ft.
How much does a 4'x12'x4' slab of concrete weigh?
A cubic foot of concrete weighs ABOUT 150 pounds. 4 feet by 12 feet by 4 feet is 192 cubic feet. If you meant 4 feet by 12 feet by 4 INCHES, that would be 16 cubic feet.
How much concrete is needed for a slab 120 square feet by 3.5 inches thick?
(3.5/12) x 120 = (.2917) x 120 = 35.004 Cubic Feet Concrete is sold by the cubic yard. 35.004 cubic feet = 1.3 cubic yards
