Effect of Cement, Aggregate and Water Ash on Pumping Concrete

Release time:2023-07-06

The quality of concrete not only affects the safety of the structure, but also affects the cost of the structure, which determines the safety and function of the structure. Therefore, in the construction process, measures must be taken to effectively control the various factors affecting the quality of concrete, to avoid quality problems, to achieve the purpose of prevention, to ensure the quality of concrete construction.

There are many technical problems in the concrete pumping construction of super high-rise buildings, such as equipment configuration problems, etc., and if the conventional connection and sealing method cannot meet this requirement, the pipeline system with high pressure resistance is needed. Reasonable arrangement of pipelines is the key, and equipment configuration should be based on reliability as the primary principle.

Before pumping concrete, the water in the storage hopper is pumped out of the pipeline to wet and clean the pipeline, and then the cement mortar with the same proportion as the concrete is added into the hopper, and the concrete can be pumped after the pipeline is lubricated. At the beginning of pumping, the pumping speed should be slowed down, and the oil pressure change should be within the allowable range. When the pumping is smooth, the normal speed should be used for pumping.

Which concrete to choose? Self-mixed concrete VS commercial concrete

Self-mixing concrete is made by manual mixing, cement, sand and water. The self-mixing method is usually mixing with a small mixer. The mixing amount is relatively small, and it is all manually mixed, so it is easy to cause uneven ratio and the strength is not particularly stable.

How to solve the large concrete collapse

The aggregate contains large mud, so air entraining and water reduction can be appropriately increased.
