Since alite is the most reactive cement mineral that contributes significantly to concrete strength, more alite should give better early strengths ('early' in this context means up to about 7 days). However, this statement needs to be heavily qualified as much depends on burning conditions in the kiln.
Mixing Concrete Let DIY Doctor show you how to mix concrete with this Project and Video Tutorial. Explains what sand to cement ratio you need for your Concrete Project. Find out how much cement and aggregate you need to buy using our concrete calculator. A guide on how to mix concrete for different applications.
How Much Sand Is Required to Lay Concrete Blocks?. The unfortunate side effect of building for a home is that there are so many angles of a project that ordering materials can be an overwhelming process. Take, for example, concrete blocks. While there are some estimates for the average block size, the reality is that custom blocks and numerous...

This is based on the fact that only about unit of water (by mass) chemically combines with cement during hydration. However, for a given volume of cement to hydrate completely, there must be an amount of original mixing waterfilled space equal to times the solid volume of the cement.
May 28, 2010· By Adam D. Neuwald. Two of the most commonly specified requirements for concrete used in the manufactured concrete products industry are the design compressive strength (f' c) and the maximum watertocement ratio (w/c).These two values are inversely related, which means that as the watertocement ratio increases, the compressive strength decreases.
Example calculation Estimate the quantity of cement, sand and stone aggregate required for 1 cubic meter of 1:2:4 concrete mix. Ans. Materials required are 7 nos. of 50 kg bag of cement, m 3 of sand and m 3 of stone aggregate.
How much concrete do I need and how long between loads. We have provided a volume calculator for your convenience. Small loads incur extra surcharges so it is always best to get your quantities right to avoid extra expense and delays in service. Is there any specific site/truck requirements for the job.
Post Hole Concrete Calculator Calculate how many yards or how many bags of concrete are needed for a set of post holes by entering the post diameter and hole size. If you're not sure what size hole to dig, a rule of thumb is to use a hole diameter 3 times the post diameter and 1 ⁄ 3 as deep as the post height.
Airentrained concrete is produced using airentraining portland cement, or by the introduction of airentraining agents, under careful engineering supervision, as the concrete is mixed on the job. The amount of entrained air is usually between four and seven percent of the volume of the concrete, but may be varied as required by special ...

How To Calculate How Much Concrete I Need. This means the "density" of concrete is about 145 lbs per cubic foot. Now that we have that information we can calculate the yield. Add up both the dry material in the bag (80 lbs) and the water it takes to mix it up (1 gallon which weighs lbs) for a total weight of lbs. Then divide the total weight by the density of the concrete.
These Concrete Calculators work out the required cement and allin ballast or cement, sharp sand and gravel required to complete a user defined volume of finished concrete. Both concrete calculators make an allowance for the fact that ballast etc losses volume when mixed to make concrete.
