Epoxy grout, a compound consisting of epoxy resin, epoxy hardener, and sand or aggregates, plays a crucial role in various construction applications. While the term “grout” might suggest the presence of cement, epoxy grout contains none. Instead, the hardening process is initiated by the epoxy hardener, facilitating the formation of a durable and adhesive material. This type of grout is commonly used to repair hairline cracks and cavities in concrete structures, and it can also function as a primer or bonding agent.
Cement grout, on the other hand, is created by combining cement powder and water, with a ratio similar to that of concrete. Its performance is significantly influenced by the setting and hardening processes, and the presence of excessive voids can compromise its strength, stiffness, and permeability. Nevertheless, cement grout finds versatile applications in filling voids and gaps within structures.
Finally, cement mortar, a mixture of cement, water, and sand, is commonly used as bedding material for concrete kerbs in roadwork projects. It provides a stable base and ensures proper load transfer, contributing to the overall longevity and performance of the road infrastructure.
In summary, while the terms “grout” and “mortar” are often used interchangeably, their composition and applications can differ significantly. Epoxy grout, devoid of cement, excels in repair and bonding applications, while cement grout and mortar find uses in filling voids and providing structural support, respectively.
