What is cement grouting?
Cementitious grouting is a process in which a fluid cementitious grout is pumped under pressure to fill forms, voids, and cracks. It can be used in several settings including bridges, marine applications, dams, and rock anchors. The grouted mass has an increased strength, stiffness, and reduced permeability.
What is grouting in prestressed concrete?
Grouting of the post-tensioned cables in the post or prestressed concrete is carried out to provide permanent protection to the steel cables against corrosion. It also develops a bond between cables and surrounding concrete which fills the duct space and prevents water collection and freezing.
What is density of GP2?

What is the difference between epoxy and grout?
Traditional grout is made from a cement based mix. It’s not waterproof and actually absorbs water when it becomes wet. It also absorbs stains easily, as anyone who has scrubbed grout will attest to. Epoxy grout on the other hand, is made of epoxy resins combined with a filler powder.
What is GP2 material?
Conbextra GP2 is a blend of Portland cement, graded fillers and chemical additives which impart controlled expansion in the plastic state whilst minimising water demand. The low water demand ensures high early strength. The graded fi llers are designed to assist uniform mixing and produce a consistent grout.

What is the meaning of grouting in construction?
Grouting in civil engineering refers to the injection of pumpable materials into a soil or rock formation to change its physical characteristics. It is one of the ways ground water can be controlled during civil engineering works.
Is grouting waterproof?
All cement-based grouts are water resistant so they all allow the passage of water through them without breaking down. The more polymer that is in the grout the greater the resistance to water penetration.
