Concrete batching machine is an important part of concrete mixing plant. How to do ratio about concrete batching machine? This is each concrete batching machine controls and operation staff needs to learn and pay attention to the most basic common sense. Would also like to know what concrete batching machine per cu m of water consumption of concrete to determine, shall comply with the following requirements:
1. The water consumption rule of dry and plastic concrete about concrete batching machine:
1) Cement ratio in the 0.40~0.80 range, based on coarse aggregate species, size and construction of the concrete mix to a consistency to determine its water consumption.
2) Cement ratio less than 0.40 concrete and using special molding concrete water should pass the test.
2. Liquidity and high fluidity concrete calculation of concrete batching machine water consumption according to the following steps:
1) slump in concrete batching machine according to the table of 90mm water based slump increases 20mm water consumption increases by 5kg, calculated without using additives, concrete consumption;
2) Using additives of concrete water according to the following formula: MWA=mw0 (1-β): MWA-consume more water per cubic meter of concrete with admixture of concrete (kg); Mw0-consume more water per cubic meter of concrete when not using additives (kg); Water reduction of β-admixture, and β-=10.00%.
3) Admixture of water reduction rate shall be determined by the test. Due to the water cement ratio of concrete batching machine is less than 0.40, so take test data mw0=150.00kg water. MWA=150×(1-0.10)=135.00kg。
