When designing the concrete mix proportion in a concrete mixing plant, the following three principles can be followed:
The first point is the principle of water cement ratio
The proportion of water cement ratio can be taken within the allowable range as long as it meets the design requirements.
The second point is the principle of water consumption
This principle, also known as the principle of minimum slurry to bone ratio, refers to using as little water, less ash, and more aggregates as possible while ensuring the working strength and performance of the concrete mixing plant, in order to reduce the shrinkage and cracking phenomenon of concrete and ensure the volume stability of concrete. Of course, the water consumption actually reflects the parameter of the slurry to bone ratio. The larger the water consumption, the greater the amount of ash used, and the greater the total amount of slurry in the concrete.
The third point is the sand ratio principle
The sand ratio is the proportion of sand and gravel, and the higher the sand ratio, the lower the elastic modulus of concrete.
Concrete practitioners also need to have a certain level of technology and proficiency to conduct tests on the designed concrete mix proportion, and be able to make corresponding adjustments based on the test results and specific situations. Moreover, the concrete mix proportion can be adjusted in a timely manner based on the condition of raw materials and the engineering situation, which is the key to design.
