Rapid 260AF is a liquid non-alkaline sprayed concrete for use in a wide range of sprayed concrete applications which require rapid development of early strength, with no or minimal reduction in ultimate strength of the concrete.
| Appearance | yellowish liquid |
| Dry Matter: | 50% |
| pH: | approx 3 |
| Chloride Content: | nil |
| Viscosity: | 250 mPa.s (20°C) |
Rapid 260AF can be used with all types of Portland Cement, including Sulphate Resisting Cement, however site trials to assess dosage are recommended.
For use with special cements we recommend that you consult GCP.
Rapid 260AF should not be pre-mixed with other admixtures prior to addition to the mixture. The performance of the material may be affected by the presence of other chemicals. We recommend that GCP be consulted in such circumstances.
As with most products of this type, the magnitude of the effect obtained with Rapid 260AF is governed by the quantity of product used, cement source, water-cementitious ratio, and the ambient temperature and the substrate temperature. Therefore, the performance of Rapid 260AF is best assessed after preliminary trials on site using actual site materials.
For advice and assistance with your trials we recommend that you consult GCP Applied Technologies.
Rapid 260AF is supplied in 1000 litre free, non-returnable containers.
Alternatively, bulk deliveries can be arranged.
Rapid 260AF should be stored in polypropylene, polyethylene PVC or stainless steel tanks. It should not be stored in mild steel tanks as corrosion will occur.
Rapid 260AF should be stored at temperatures below 35°C to prolong shelf-life. Protect from direct sunlight.
Protect from frost. If the product does become frozen, it should be carefully mixed after thawing out to restore it to its normal state.
The effects of overdosing Rapid 260AF are a function of the degree of overdose.
Depending on the extent of the overdose, a decrease in the setting time may occur causing difficulty with spraying and reduced adhesion.
It is preferable that liquid admixtures for sprayed concrete be introduced into the mix at the nozzle by means of a simple hose pump or reciprocating pump.
Rapid 260AF is a weakly acidic product, therefore we recommend taking the same safety measures for the handling of the product as for cement containing products.
Rapid 260AF is formulated from chemicals which present no fire hazards. If, however, it is spilt the floor will be made slippery and should be washed down immediately with cold water.
