A simple formula tells you the water consumption of concrete admixtures

concrete mix ratio: ①cement ②coarse aggregate ③fine aggregate ④additives calculation method: ordinary concrete mix ratio calculation book basic “common concrete mix proportion design regulations” (jgj55-2000) (j64-2000) and “building construction calculation manual”. 1. calculation of concrete preparation strength concrete preparation strength should be calculated according to the following formula: fcu, 0≥fcu, k+1.645σ where: σ——standard deviation of concrete strength (n/mm2). take σ=5.00 (n/mm2); fcu, 0——concrete preparation strength (n/mm2);…
