How Does A Mobile Concrete Mixer With Pump Work
Jan 12, 2021
The concrete pumping is different from the traditional concrete construction methods. In addition to meeting the design requirements for strength and durability, the concrete should have a good pumpability.
The so-called pumpability means that the concrete mixture should have the characteristics of being able to flow smoothly through the pipeline, with low friction resistance, no segregation, no clogging, and good adhesion.
When we use mobile concrete mixer with pump to produce and pump concrete, we need to operate it correctly. The main parameter of the concrete mixer machine with pump is the pumping capacity. Pumping capacity is generally expressed by the maximum delivery volume (displacement) and the maximum delivery pressure of pumping concrete per hour.
It is based on specific conditions such as concrete quality, proportion, aggregate gradation, sand ratio, water-cement ratio, slump and concrete pipe arrangement during pumping operation. So what are the requirements of the mobile concrete mixer with pump for the concrete raw materials?
Cement
Cement is a hydraulic cementing material. General-purpose cements include Portland cement, ordinary Portland cement, and Portland slag cement, etc.
Fly ash
Fly ash is a commonly used admixture for pumping concrete. Adding finely ground fly ash to pumped concrete can significantly improve the fluidity of the concrete mixture, reduce drying shrinkage, and significantly improve the pumpability of concrete.
Sand
River sand is commonly used in general engineering.
Stones
Stones are divided into igneous rocks, sedimentary rocks, and metamorphic rocks according to their geological origin. Most igneous rocks are excellent raw materials for stone.
Additives
The material that is mixed during or before mixing, and the mixing amount is not more than 5% of the weight of the cement, and can change the performance of concrete as required, is called concrete admixture.
