NEOGROUT CABLE FLOW

Expanding plasticising admixture for cement, grout and concrete

NEOGROUT CABLE FLOW is an expansion system, which compensates for plastic shrinkage and settlement in cementitious grouts. Supplied in powder form, it produces controlled expansion in cement grouts and maintains high water retention. It contains a water-reducing agent, which increases the workability of the mix with reduced water content, making a stronger grout. Full expansion is achieved before initial setting occurs resulting in a high degree of interfacial contact.

Properties

The expansion of grouts containing NEOGROUT CABLE FLOW is sufficient to overcome normal settlement without producing undue pressure against the sides of the duct. The grout therefore forms a firm and uniform bond to the concrete and to the steel along the length of the tendon, and at the same time provides good protection for the cable. The expansion obtained by the use of NEOGROUT CABLE FLOW reaches a maximum within 1-2½ hours of mixing under average temperature conditions. After this period no settlement occurs, and the grout retains its maximum expansion. NEOGROUT CABLE FLOW produces a maximum expansion of 3.25% in a neat cement grout, and 2% expansion in a 1:1 sand/cement grout.

Plasticising properties:
NEOGROUT CABLE FLOW imparts fluidity to grout, even at reduced w/c ratios, and because of the water reducing action, higher compressive strengths are obtained

Applications

For bedding, jointing, duct grouting and void filling applications where the following characteristics are beneficial:

– A cement plasticising and water-reducing agent to improve the free flowing properties of the grout at low w/c ratios
– An expanding agent that increases the volume of the grout, which in turn eliminates shrinkage and settlement
– A catalyst to control the rate of expansion and to ensure full expansion of the grout.

Packaging

NEOGROUT CABLE FLOW is available in 15 Kg Bags.
