BRONCO® NSPG is Polymer modified non-shrink admixture for injection cement grouting.
Area Of Application
It is used as an admixture for Injection Grouting to effectively
waterproof and stop leaks in underground structures, basements, tunnels, lift wells, retaining walls, dams, water reservoirs, pressure ducts and other water retaining structures. It is also recommended for grouting pre-stressed members.
Machine bases, column bases (Steel and precast concrete) anchor bolts etc. and wherever a non-settling,Non-bleeding, expanding grout is required.
An additive to produce flowable Expansion (non-shrink) concrete (with smaller sized graded aggregates are preferable) / mortar.
Advantages
Drastically improves the fluidity and flowability of the mix.
Ensures high early strength and rapid gain of later strength
Increased flexural and tensile strength.
Provides additional resistance to dynamic and repetitive loading.
Compensates cement shrinkage by controlled expansion.
Withstands thermal movements to provide improved dimensional
stability
