how much concrete for a 40 foot towerhow much concrete for a 40 foot tower
The density varies between 3000-4000 kg/m. Just divide the total weight needed by the weight in each bag. Following the mix ratio, we can calculate the volumes of sand and gravel required, as shown below: cement volume = total concrete volume / sum of terms, cement volume = 2 cu yd / (1 + 2 + 4) = 2 cu yd / 7 0.286 cu yd (0.214 m), sand volume = 2 * cement volume = 2 * 0.286 cu yd = 0.572 cu yd (0.429 m), gravel volume = 4 * cement volume = 4 * 0.286 cu yd 1.144 cu yd (0.857 m). After 28 days concrete achieves around 99% of maximal compressive strength.

Then use the calculator to figure the amount of concrete needed. Jointing Sand is This Product Order Supplies the Following BOM (Less Foundation and Installation) in accordance for Use as a Self Supporting 40 Foot ROHN 25G Tower with with EPA's (Effective Projected Area) Ratings for 70, 80 or 90 MPH (No Ice). - Seal Cracks and Joints. Not enough paste will result in rough, honeycombed surfaces and porous concrete. This way, you can also estimate the concrete slab cost. a 2", If not, again, change it to the appropriate number. Then use the calculator to figure the amount of concrete needed. b) The minimum boring depth should be 30 feet for pole structures, self-supporting towers and guyed tower bases. applications o Cross bracing is formed by a continuous solid rod bracing in a zig-zag pattern for strength. and place 3 feet in the ground). See ROHNs standard design to help identify the right structure for your project. Pre-mixed concrete is usually sold by the cubic yard, and this unit is used by default. Are you on a hill top, or in a valley? Use the following yields per each bag size: Larger jobs such as driveways are easier to complete when ordering concrete by the yard, rather than trying to mix bag after bag by hand. On average, a 2,200-square-foot concrete house costs $340,000, or between $240,000 and $445,000. Concrete mix ratios determine the strength of the resulting concrete.
