Calculating a Concrete Order – B4UBUILDA = 48 feet x 26 feet; A = 1,248 square feet; However, this figure actually only represents the surface area of the concrete – note that the answer is in square feet. To find the volume of concrete, you still need to multiply the surface area by the height or depth of the concrete in order to get cubic feet of concrete.

Ratios and Proportions : Key Skills (or Basic Skills) in ...Introduction. Ratios occur in mixing things such as concrete which is made of cement, sand and gravel in a definite ratio. For example, a ratio of 1:3:4 would mean that no matter what volume of concrete you have, 1 part is cement, 3 parts is sand and 4 parts is gravel.
How to Evaluate Cracks in Poured Concrete SlabsBefore we describe crack, movement, and damage patterns and diagnosis in concrete slabs, we need to introduce three different types of poured concrete floor slabs. We use the three Carson Dunlop Associates Sketches shown here to comment on the occurrence, causes, and significance of cracks and movement in poured concrete slab construction.
Sand / Media Specificationsmedia for intermittent sand filters is a coarse sand with an effective size between mm and mm. The media sand grains should be relatively uniform in size having a low Uc value (less than ) to promote movement of water and prevent clogging. KEYWORDS: sand/ media specifications.
