Specification of Sika Intraplast Z Expanding Agent
DESCRIPTION
An expanding grout admixture in powder form. By introducing micro bubbles into the mix, it produces wet volume expansion and increased fluidity without segregation.
USES
Intraplast Z is used to increase cohesion in cement grouts and is suitable for use in the grouting of :
▪ Pre-stressed cable ducts
▪ Rock and soil anchoring
▪ Bearing plates.
▪ Pre-placed aggregates.
▪ Tunnel linings.
▪ Pre-cast concrete elements.
▪ Tilt construction wall panels.
▪ Crack injection
CHARACTERISTICS / ADVANTAGES
▪ Intraplast Z plasticises the mix with water reduction of up to 20%, thus improving the strength of the grout.
▪ Gas generated during setting distributes bubbles causing expansion to take place (3%-8% by volume) thus compensating for normal shrinkage. The initial retarding effect of Intraplast Z improves grout penetration, reduces water separation and bleeding.
▪ The expansive forces generated completely fill voids.
▪ Non toxic, non chloride.
