Application of Laser Particle Size Analyzer in Medium-heat Cement

Medium-heat cement is a specialty cement with the key advantages of a moderate heat of hydration and strong resistance to sulfate attack. Through strict control of its chemical composition, it effectively prevents cracking of large concrete volumes due to temperature fluctuations and resists corrosion from seawater and groundwater. It is mainly used in water conservancy projects (such as dams), marine structures (such as ports) and underground projects.

The particle size distribution of medium-heat cement in the test is crucial as it directly determines the core properties.

1. Precisely control the heat of hydration. Particle size distribution influences the hydration rate. Optimizing this distribution can prevent premature hydration and concentrated heat release, effectively preventing cracking in large concrete volumes caused by internal and external temperature differences. This is the primary task of medium-heat cement.

2. Coordinate strength development with construction performance. Reasonable distribution ensures balanced early and long-term strength development, while optimizing cement water demand and paste fluidity to ensure construction quality and efficiency.

3. Ensure product quality stability. Particle size is a key control parameter in the production process. Continuous testing is necessary to achieve product uniformity and meet high standards.

By analyzing the particle size and distribution, the hydration behavior, ultimate strength and construction performance of medium-heat cement can be precisely controlled, which is the core test link for whether its performance can meet the standards.

This time, Winner2309A is recommended to test the particle size distribution of coatings for customers. As a new generation of intelligent wet and dry laser particle size analyzers, the winner2309 represents a significant leap forward in appearance, measurement range, intelligence, and test intervals. Its measurement range is 0.01-3500μm. It is mainly used to test the particle size of metal powder, non-metal powder, other powders and emulsions, etc.
