Application of laser particle size analyzer in fine sand

The fineness modulus of fine sand is less than 2.3, and its sieve residue at 4.75mm, 2.36mm, and 1.18mm grades is small, and the content of particles with a particle size smaller than 0.315mm is high. The small particle size, small fineness modulus, and large surface area of fine sand cause increased water consumption in concrete. If measures are not taken to reduce water consumption, it will have an impact on the durability of concrete, such as cracks and reduced strength.

It can be seen that the particle size detection of fine sand particles is particularly important. This time, Winner2008 is recommended to measure fine sand particle samples for customers.

Measuring instrument information is as follows:

The video of measuring nanoparticles is as follows：
