The mositure volume impact for concrete batching plant

We know that a certain proportion of concrete is made by mixing sand, cement, additives and water through a single large sand and gravel aggregate moisture or rain weather is higher, will be on the ready-mixed concrete batching plant to produce mixed concrete great impact, let’s look at the concrete mixing sand and gravel aggregate excessive moisture impact on what?
First, the impact is expected on the part of aggregate will cause the belt sticky material phenomenon, reducing the ratio of the amount of concrete aggregate, affect the quality of concrete.Second, the most vulnerable to the impact of sand moisture content of water is added to C30 concrete cementitious material per cubic amount of 400kg, water 180kg, 1800kg count the amount of sand, gravel moisture decrease 1-18kg, water-cement ratio will decrease about 10.By measuring the amount of water we should take some of the ways to reduce the moisture content of sand, we need the following:the stability of gravel sources;sand particle size distribution issue, different gradation, grain shape different moisture content;by strengthening the detection of the workability of concrete slump to reverse the deduction for moisture detection accuracy;for a known mixture ratio, if the machine and the test results in line with the case that the water content of the sand to be accurate;
through the sand and gravel processing and re-mixed, mixed with a lot of powder, to control the moisture content for concrete.The professionalism and technical personnel and operational personnel, appropriate adjustments based on experience.Any more about pan mixer concrete batching plant, pleae feel free to contact us.
