Measured the actual density of the concrete mixture for the 2450 attackers Ju Ju-hui angle to carry hair kg / m3. Such as site sand moisture content of 2.5%, stone moisture content of 0.5%, seeking construction mix. More
Construction ratio: cement 3.1kg, water = 1.86-6.24 × 2.5% -12.4 × 0.5% kg, sand = 6.24 × (1 + 2.5%) kg, gravel = 12.4 × (1 + 0.5%) kg. The formula has been listed, the results of their own on the line
Cement: water: sand: gravel 3.11.866.2412.4 construction of the attackers Ju Juqi licensing to carry hair with the ratio: 1: 0.529: 2.06: 4.023.1 = 1.86-6.24 * 2.5% -12.4 * 0.5% = 1.642 = 6.24 * (1 + 2.5%) = 6.396 = 12.4 * (1 + 0.5%) = 12.462 What is the name of your concrete, water recovery is too large, need such a large dam degree?
. Calculate the compounding ratio: 3.1 + 1.86 + 6.24 + 12.4 = 23.6 cement = (3.1 / 23.6) x 2450 = 322 water = (1.86 / 23.6) x 2450 = 193 sand = (6.24 / 23.6) x 2450 = 648 stone = (12.4 / 23.6) × 2450 =, construction with the attackers to play the trickle than the amount of cement than the amount of cement = 322 sand = 322 × (1 + 2.5%) = 330 stone = 1287 × (1 + 0.5%) = 1293 Water = 193- (330-322) - (1293-1287) = 179 Unit: kg / m?
