With the concrete pouring concrete, cement, gravel, gravel need to do raw materials check it
According to the national requirements of the ingredients used in the site must be sent to the test station detection.
Too little cement. 46 cubic concrete, should use 2300KG cement, thickness . stone only with the largest 4CM. , 32.5 in the amount of 2100Kg, 42.5 in the amount of 1800Kg, the amount of sand and gravel by 1: 1.5 engineering
You ask the question I can not start, simple and you talk about it, a cubic concrete with stones, cement, sand, not I can do here to count you, the concrete is labeled. C. C. C30 These are the strength grade, the grade is different, the concrete mix ratio is not the same, the concrete mix ratio is stone, cement, sand material after the inspection in the laboratory to complete, as for the low environment, with experience Than, for example, build their own house, you can ask the next time; C20 concrete cubic material experience the amount of how much? 400 # This argument has been canceled on the unit area to withstand 400 kg pressure is very good Oh, you can try mjЬe Ting k
Raw material inspection by the commodity concrete company to do, they give users with the ratio and raw materials experimental report
