? Concrete composition for the manufacture of a concrete pole for electric power distribution, and post concrete?

摘要

In order to achieve the goals described above, the present invention provides a composition of concrete to manufacture a concrete pole for electric power distribution.The composition of concrete comprising cement in a concentration of 294 to 429 kg / m u00b3 of concentrate, sand in a concentration of 446 the 897 kg / m u00b3 of concentrate.Gravel classification 0 with concentration between 369 and 980 kg / m3 of concrete, gravel classification 1 with a concentration between 220 and 697 kg / m3 of concrete, water.In the relationship of water / cement is between 0.49 and 0.59, and ash of rice husk.The present invention provides even pole concrete for energy distribution having a metallic frame and comprising the composition of concrete is developed.
