Mixing the Concrete. For smaller projects, placing the materials in a wheelbarrow and hand-mixing with a hoe, rake, or shovel is often adequate. Larger projects might require using an electric cement mixer that spins or mixes the materials in a tub, eliminating the arduous task of hand-mixing, which can be highly labor-intensive.

Use a maximum .45 water to cement ratio for concrete with severe or very severe sulfate conditions per the 1997 Uniform Building Code (Table 19-A-4) Water permeability increases exponentially when concrete has a water cement ratio greater than .50. Durability increases the less permeable the concrete mix is.

For example concrete is made by mixing cement, sand, stones and water. A typical mix of cement, sand and stones is written as a ratio, such as 1:2:6 . We can multiply all values by the same amount and still have the same ratio.
RE: Most economical Height/Diameter ratio - Field Fabbed Tanks JStephen (Mechanical) 28 Jul 09 22:33 To complicate it all, if you evaluate the cost of different proportions of identical tanks, the tank of lowest cost will depend on which fabricator builds it.
Concrete mix ratios are prescribed ratio of cement, sand and aggregate to get the desired strength of concrete. For example, if the concrete mix ratio of M20 concrete is 1:1.5:3, then 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume should be batched to prepare M20 grade concrete.

Sep 26, 2010 · Physicist: The golden ratio, g, is . The golden ratio is defined in many (equivalent) ways but the best known is: if A and B are two numbers such that the ratio of A+B to A is equal to the ratio of A to B, then g=A/B. A rectangle, where the ratio of the long side to the short side is g, is called the “golden rectangle”.
