What are the main reasons for poor pumping performance of concrete
Poor pumpability usually refers to poor fluidity and high resistance of concrete during pumping, which can easily lead to problems such as pipe blockage and segregation.

How to construct lightweight aggregate concrete?
The construction process of lightweight aggregate concrete is basically the same as that of ordinary concrete.
However, due to the low bulk density, porous structure, and high water absorption rate of lightweight aggregates, the formulated lightweight aggregate concrete also has certain characteristics.
Only by paying sufficient attention during the construction process can the construction quality of the project be ensured.

How to assess the quality of concrete?
In the current concrete industry, due to the weak quality awareness and lack of integrity of some raw material suppliers, as well as the scarcity of resources, the quality of raw materials is unstable, which leads to the instability of concrete quality.
How should engineers on the front line of construction act to ensure the quality of concrete to the greatest extent possible when there is no time for experimental testing and trial mix adjustment? This is a problem that seems “inconvenient” to discuss, but objectively exists, frequently occurs, and urgently needs to be solved.

Research on the Influence of Coarse Aggregate Quality on the Adaptability of Concrete Water Reducing Agents and Construction Adjustments
On the premise of ensuring that other materials remain unchanged, three gravel yards were selected to produce crushed stones for selection testing.
After testing, it was found that the performance of several concrete mixtures varied greatly, especially the one hour slump loss.
The experiment reduces the sensitivity to material quality fluctuations by adjusting the composition and dosage of water reducing agents, thereby improving the adaptability of water reducing agents and improving the workability of concrete to meet the construction production of different quality coarse aggregates.

How do water reducing agent technicians adjust the state of concrete?
The concrete we are currently using is composed of cementitious materials, aggregates, water, and water reducing agents.
The state of the fresh concrete mixture depends on the quality and dosage of the raw materials, so it is particularly important to control the quality of the incoming materials and strictly follow the mix proportion and dosage.
The state of concrete mixture changes with the quality and dosage of raw materials, and we need to adjust it in a timely manner during construction to achieve the best workability.

What legal approval procedures are required for the construction of a concrete mixing plant?
Building a mixing plant is a complex system engineering that involves supervision from multiple administrative departments.
The first step in compliant operation is to handle various approval procedures in accordance with the law to ensure the legality of the construction process.
