With the rapid development of the construction industry, the requirements for the performance of building materials are also constantly increasing.

Concrete Superplasticizer PCE Powder as a new generation of high-performance concrete admixtures have shown great potential in improving the workability and durability of concrete. This article will introduce in detail the specific steps and precautions for the application of PCE powder in concrete during actual construction.

1. Preliminary preparation
 

Material selection: Ensure that the quality of the selected PCE powder meets national standards and select the appropriate model according to project requirements.

Equipment inspection: Before use, carefully check whether the construction equipment, such as the mixer, is in good condition.

Mix design: Adjust the ratio of cement, aggregate and water based on engineering requirements, and determine the reasonable amount of PCE added. Generally, the recommended amount of PCE is 0.1%~0.25% of the total amount of cementitious materials, but the optimal amount needs to be determined through experiments.
 

2. Mixing process
 

Dry mixing stage: First, add all dry raw materials (including cement, fine aggregate, coarse aggregate, etc.) into the mixer for preliminary mixing.

Add water and stir: Then, slowly add half to two-thirds of the estimated water volume, and start the mixer to rotate at a low speed.

Add PCE: When the mixture shows a certain consistency, the accurately weighed PCE powder can be evenly sprinkled in batches.

Fully stir: Continue to stir at medium-high speed for at least 3 minutes until all ingredients are completely blended and the concrete reaches the required fluidity.

Adjust the amount of water: According to the actual situation, appropriately increase or decrease the amount of water in the remaining part until the ideal slump or expansion is obtained.
 

3. Casting and curing
 

After completing the above steps, concrete pouring can be carried out. It should be noted that continuity should be maintained throughout the construction process to avoid problems such as cold joints.

After the pouring is completed, effective measures should be taken in time to implement moisturizing coverage on the surface of the newly poured concrete to promote its early strength development and reduce the probability of cracks.
 

4. Precautions
 

When using PCE, it is necessary to follow the instructions provided by the manufacturer strictly, and the dosage cannot be changed at will to avoid affecting the final effect.

When the temperature changes greatly at the construction site, attention should be paid to adjusting the amount of PCE to prevent fluctuations in concrete performance due to excessive temperature differences.

Although PCE can significantly improve the working performance of concrete, it still needs to be considered in combination with other factors, such as mix design and raw material quality, to achieve the best effect.
