Cementitious grouts for the building and construction industry
Bostik cementitious grouts are examples of how formulated products offer specific qualities to the construction industry.
Cement has a natural tendency to shrink during curing. There are two common forms of shrinkage:
- Early age shrinkage (also called plastic shrinkage) is predominantly due to water evaporating from the matrix
- Post hardening shrinkage (also called drying shrinkage) is a result of ongoing chemical reactions and hardening
Class A grouts: (also referred to as General Purpose) are non-shrink during the plastic state
Class C grouts: (also known as Performance Grouts) are shrinkage compensated (non-shrink) during both the plastic and post hardened state
