Products

This product has specially been designed as a substitute of lime addition in mortars, in which cement is used as a hydraulic agglomerative. Its strong plasticiser effect allows a reduction of water in the mixture, resulting mortars of high resistance and, at the same time, it lengthens the time in which the concrete remains workable and increases its adherence on hardened concrete.

Uses

Hipercal/Hipercal Retard is used as a liquid additive for portland cement mortars; It can be used in all those situations in which one wants to keep mortar workability for a longer time, obtaining a more manageable and thicker mortars, which reduce material losses because of detachments.
The product is of general use in the application of any kind of bricks, stuccos, tiles application, ceramic floors, etc.

Surface preparation

In roof tiles and ceramic floors it is preferable to wet the pieces before using them.

Instructions for use

The product has to be mixed with a small part of the mixing water which will be poured into the concrete mixer. Optimal mixing time is 4-5 minutes. A lesser quantity only gives the plasticiser effect, but not the hardening retardant. A bigger quantity gives a lower resistance. When the product is used with ceramic floors it is better to wet the pieces before its use.

Consumption

For the product dosage it must be taken into account that 25 ml. of the product are equivalent to 15 Kgs of powder lime.
