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.

How many wheelbarrows of aggregate are in 1 cubic metre of concrete?
The number of wheelbarrows of aggregate in 1 cubic metre of concrete depends on the size of the wheelbarrow and the aggregate's density. Typically, a standard wheelbarrow holds about 0.1 cubic metres of material. Therefore, you would need approximately 10 wheelbarrows of aggregate to fill 1 cubic metre of concrete, assuming the wheelbarrow is filled to capacity.
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 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 much portland cement sand and gravel for a yard?
To make one cubic yard of concrete, you typically need about 1 part Portland cement, 2 parts sand, and 3 parts gravel. This translates roughly to 1 bag (94 lbs) of Portland cement, 0.5 cubic yards of sand, and 0.75 cubic yards of gravel. Adjustments may be needed based on the specific mix design and desired strength. Always consult local guidelines or concrete calculators for precise measurements.
How much sand stone and cement do i need to cast 41 yards of concrete?
To cast 41 cubic yards of concrete, you typically use a mix ratio of 1 part cement, 2 parts sand, and 3 parts gravel (aggregate). For 41 yards of concrete, you'll need approximately 6.8 cubic yards of cement, 13.6 cubic yards of sand, and 20.4 cubic yards of gravel. Adjust the mix based on specific project requirements or concrete strength needed. Always consider adding water based on the moisture content of the materials and desired workability.
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 much sand and gravel and concrete to make one yard?
To make one cubic yard of concrete, you typically need about 1.5 tons (or 3,000 pounds) of sand and gravel combined. The standard mix for concrete is roughly 1 part cement, 2 parts sand, and 3 parts gravel, along with water. This means you would generally use about 0.5 cubic yards of sand and 0.75 cubic yards of gravel for each cubic yard of concrete. Adjustments may vary based on the specific mix design and desired strength.
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.
How many wheel barrows in a ton of gravel?
The number of wheelbarrows in a ton of gravel can vary based on the size of the wheelbarrow and the density of the gravel. A standard wheelbarrow typically holds about 6 cubic feet, and a ton of gravel is approximately 20 cubic feet. Therefore, you would need about 3 to 4 wheelbarrows to transport a ton of gravel, depending on how full each wheelbarrow is loaded.
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.
