Cementitious Grout in Construction: Essential Facts You Should Know
Wiki Article
Cementitious
grout is a mixture primarily composed of Portland cement, sand, water, and
sometimes additives to enhance its performance. It is widely used in
construction for filling voids, sealing joints, and providing support between
structural elements such as tiles, precast concrete, and masonry units.
Cementitious grouts are known for their high compressive strength and
durability, making them suitable for both residential and commercial
applications, including flooring, tiling, and infrastructure projects. These
grouts are available in sanded and unsanded types—sanded grout is typically
used for wider joints, while unsanded is preferred for narrow spaces.
One of the major advantages of cementitious grout is its
ease of use and cost-effectiveness. However, it can be prone to cracking and
shrinking if not applied or cured properly, especially in high-moisture or
high-movement environments. To overcome such limitations, polymer-modified
versions are available that offer enhanced flexibility, adhesion, and water
resistance. Proper surface preparation, mixing, and curing are essential to
ensure the longevity and performance of cementitious grout in construction applications.
