The Cement Consumption of Concrete Batching Plants
How to do according to the different ingredients of concrete batching plants to select a reasonable amount of cement to control it?
Cement is one of the most important raw materials for concrete in concrete mixing plant. Scientific proportioning can not only produce high quality concrete, but also reduce the input of raw materials and manpower and material resources, and fundamentally reduce the production cost of concrete.
(1) the relationship between the amount of cement and conveying resistance and volumetric efficiency of concrete pump
Cement dosage should be appropriate. If the amount of cement is insufficient, the volumetric efficiency of pumping decreases, the conveying resistance increases obviously, and the concrete has poor water holding capacity, easy bleeding, segregation and clogging; if the amount of cement is too large, the concrete will be too viscous and the conveying resistance increases Large, but the volumetric efficiency of pumping little change.
(2) the relationship between the amount of cement and aggregate varieties
With the same size, graded gravel aggregate and gravel aggregate, gravel concrete cement dosage. For fine aggregate, the use of artificial sand crushed sand more than natural sand cement.
(3) the amount of cement and pipe diameter, duct length relationship
The smaller the pipe diameter, the longer the pipe, the concrete requires fluidity, lubricity, water retention is higher, so the amount of cement should be increased.
The above is the construction cement batching plant of the amount of cement, and more engineering reality, the amount of other raw materials can be compared, according to the different ingredients, a reasonable amount of cement to control, you can produce the right concrete.
