Concrete strength is measured by "bag mix", meaning that the bag mix answers the question, how many bags of cement per yard of concrete.

If you're looking for a "6 bag" mix, that means 6 bags of cement per yard of concrete. A "bag" of cement is 1 cubic foot. A yard of concrete is 27 cubic feet (3 X 3 X 3 = 27).

If you want to make a "6 bag mix" of concrete, using 1 bag of cement, you would make 1/6 yard concrete with 1 bag of cement. If you would be content with a "5 bag mix", you could make 1/5 yard.

Concrete is often defined as ratios of cement,sand,aggregate such as: 1:2:3 which is a very common mix.

For a 1:2:3 mix you would need 1/6th of the volume to be cement.

The dry ingredients are generally 1.6 x finished concrete volume.

Therefore dry volumen for 1 cubic yard = 1.6 cu yards = 43.2 cu ft.

1/6 x 43.2 = 7.2cu ft.

Therefore, if one bag is 1 cu ft we need 7.2 bags for a healthy 1:2:3 mix.

A '6 bag mix' or a '5 bag mix' are a bit short on cement.

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.

What is the dry density of cement?

The cement density is used in the calculation of the total aggregate content and of the concrete density.Normal concrete has a density around 2400 kg/cubic meter or 4048 lb/cubic yard. There are many different kinds of concrete, many of which are much lighter. Cement is the liquid (or paste like) form, and tends to be much heavier than when it has cured into concrete. "Cement" is not concrete, but can be used to make concrete by mixing with sand, stone and water. The density of cement is about 3120kg/m3.

How much is the ratio of cement and sand to make concrete?

The ratio of sand and cement affects the tensile strength of the concrete. Hence, a ratio of 1:2 (cement to sand) will yield a greater tensile strength than a 1:3 ratio. However, both are acceptable in the formation of concrete.


A six sack of concrete mix has how much cement in it?

The answer is, remarkably, 6. Answer: "6 sack" or "6 bag mix" has six bags of cement per cubic yard of concrete mix. Since each sack/bag contains 94 lbs of dry cement, this equals 564 lbs of cement per cubic yard of concrete.

How did they make cement in the ancient times?

Cement or concrete was actually made very much the same way as present day concrete. The Romans used an aggregate which could be of rock, broke tiles, or brick rubble, held together with a binder of gypsum or line. The very best concrete had a volcanic ash or "pit sand" as part of the ingredients.Cement or concrete was actually made very much the same way as present day concrete.
