Shrinkage expansion rate is a physical quantity that reflects the degree of deformation of building materials. It is an effective means of studying the physical properties of building materials and a necessary detection device for preventing deformation phenomena such as cracking and hollowing of building materials. Especially for institutions researching building material formulas and additives, measuring the shrinkage and expansion rate is particularly important.
Which industries require measurement of contraction and expansion rates?
1. Self leveling industry.
For example, gypsum self leveling and cement-based self leveling.
2. Mortar industry.
Such as concrete, pre mixed mortar, dry mixed mortar, waterproof mortar, insulation mortar, special mortar, grouting material, masonry mortar, plastering gypsum, etc.
3. Ceramic tile adhesive industry.
4. Epoxy floor paint industry.
5. Grinding stone industry.
What are the standards for shrinkage and expansion rate?
In order to enable everyone to quickly understand the information related to shrinkage and expansion rate, standards from different industries have been collected for reference.
