It depends on the mix of concrete you are using. A basic 1-2-3 mix is 5 1/2 cubic feet of portland cement (a wheelbarrow, depending on its size, holds 1/2 to 1 cubic feet), 11 cubic feet of sand, and 16 1/2 cubic feet of stone (called aggregate) from 1/2 to 1 inch in size each. To this is added about 12-15 gallons of water.(1 1/2 to 2 cu.ft.). This will make just a little less than 1 cubic meter of concrete.
A weaker mix for basic work not needing structural strength a 1-2-3 mix of 1 part stone, 2 parts cement and 3 parts sand can be used, this would require a bit less than 1 part water.
A stronger mix of 1 part cement, 1 1/2 parts sand and 3 parts stone with about 1/2 part water is good for heavy duty concrete work. Stone will increase the strength of concrete and sand will weaken it. Using too much or too little water in the mix will weaken it as well. Additionally, concrete with too much water or too little cement tends to shrink and crack as it sets. The amount of water to use is mainly dependent on the cement in the mix. There should be at least half as much cement as sand in any mixture. The amount of stone to use should be between 1/4 and 3/4 of the total mixture. Grouts and mortars use no stone and may add limestone as an additional binder. These should not be used for structural concrete, but can be used for foundation pointing, bolt anchoring or mortaring brickwork.

Cubic Meters Per Hour:A measurement of airflow that indicates how many cubic meters of air pass by a stationary point in one hour. Cubic meters per hour is abbreviated m³/hr.
What is cfm in HVAC?
Short for cubic feet per minute, a measurement of the velocity at which air flows into or out of a space.

How much sand gravel and cement do you need to make 1 cubic yard of concrete?
500 pounds cement, 1500 pounds sand, 1600 pounds gravel. Mix with 32 gallons water
How many cubic meter per 1 bag cement 40 kg?
One cubic meter of concrete is equal to 1.308 cubic yards of concrete. If there are 5 1/2 bags of cement in 1 cubic yard of concrete, there would be 7.2 bags in 1 cubic meter of concrete. These are the 94 pound bags of portland cement or roughly 40kg bags so figure 8 bags total. Some will be left over
How many cubic feet can a cement truck hold?
That depends on what size the concrete truck is. A 10-yard truck carries about 270 cubic feet when full. An 8 cubic yard truck carries about 216 cubic feet of concrete. (Or gravel, sand, etc)
How much sand is needed for one cubic feet concrete?
Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot. At 100 pounds per cu ft that is about 25-35 pounds.
How do I calculate the amount of cement needed?
First, things are not made of cement- they are made of concrete- which consists of cement, sand, gravel and water. Mix them using 1 part cement, 1.5 parts sand, 3 parts gravel. To calculate how much CONCRETE you need, multiply depth X width X length in inches, then divide by 1728. This will tell you the number of cubic FEET of concrete. To get the number of cubic YARDS, divide the cubic feet by 27. If you are using packaged concrete mix (Sakrete is one) then an 80 lb bag makes 0.6 cubic feet of concrete. NOTE: If you are working with concrete for the first time- do not add too much water (weakens the concrete) and do not get wet concrete on bare skin- it will cause a chemical burn. Wash it off promptly if you do.
Mixture combination of 1 cubic meter concrete?
The mixture depends on the concrete strength, flow properties and other specifications required, quality of cement, aggregates and other chemical additives that will be used. Typically 1 cubic meter concrete should include about 310kg cement, 800kg sand, 900kg gravel and 220kg water.

How many bags of pre-mix cement is needed to mix 1 cubic yds?
Cement comes in bags that weigh 94 lbs. The volume of the bag is approximately 1 cubic foot. If you want to mix concrete which is a mixture of a coarse aggregate (gravel) and a fine aggregate (sand) and something to bond the two aggregates together (cement) then firstly you need to know the strength concrete that you require. For 1 cubic yard of 3000psi (pounds per square inch) strength you will need about 6 bags cement 12 cubic feet of sand and 24 cubic feet of gravel. Rule of thumb is the ratio should be 1:2:4 (cement:sand:gravel)
How many wheelbarrows of sand make a cubic meter using a concrete wheelbarrow the normal one?

How much surface will a yard of cement cover 3 inches thick?
Concrete is a mixture of cement , sand, gravel and water. A cubic yard of concrete is 3' x 3' x 3' . That's 3x3=9x3=27 . 27 cubic feet = 1 cubic yard . So it's 27 feet divided by 3 inches equals 108 sq ft!
