Details

EVERBUILD ZEROMIX CFF is air entraining chloride free liquid admixture for mortar and concrete which also acts as an accelerator for work in sub - zero temperatures. Improves workability and freeze/thaw resistance in brick laying mortars and eliminates       the need for a separate frostproofer. Conforms to EN934-3 (2009)    

 

Benefits

  • Increased frost resistance during setting.
  • Non - corrosive to imbedded metal (chloride ion free)
  • Eases tamping down and alignment
  • Improves workability/trowelability even in cold weather.
  • Provides resistance to freeze/thaw cycling down to -8oC in both wet and dry mortar.
  • Chloride free (chloride ion content < 0.1%).
  • Reduces bleeding/segregation.
  • Replaces lime in mix, hence reduces possibility of lime bloom and efflorescence.
  • Reduces shrinkage (cracking and crazing reduced). 
  • Faster finishing times even in cold weather.

 

Areas For Use

As an air entraining water reducing admixture and accelerator/frostproofer for brick and block laying mortar, render (internal and external) and concrete. Accelerates setting time during cold periods. Suitable for:

  • Load bearing brickwork
  • Block laying
  • External/Internal rendering
  • Pointing/repointing brickwork.
  • Floor screeds      

                             

Surface Preparation

All materials used must be free from ice and the temperature of the mix prior to placing not be less than 4oC. Concrete must be covered after placing until the minimum strength is obtained or until the temperature rises above freezing. Do not use weak mixes during cold weather.

 

Application

Work should be carried out in accordance with the methods outlined in the Code of Practice BS5628 Part 3 for protection and use of mortars at low temperatures and  DOE Advisory Leaflet No. 8. In all cases, add to mix at an addition rate of 2.5 to 5 litres per 50kg cement depending on the degree of plasticising/acceleration required. Note: remember to reduce required quantity of water accordingly. Alternatively, add to mixing drum at same time as water.

                                                 

The following are examples of modified mix designs.

 

1: 0.25 :3  cement : lime : sand.                      .

          use 1 : 3  cement : sand : + ZEROMIX CFF

 

          1:1:6 cement : lime : sand

use 1 : 6  cement : sand + ZEROMIX CFF

 

BRICKLAYING/POINTING              Use a mix design appropriate to brick strength (1 : 3  to 1 : 6).

 

INTERNAL RENDERS          1 : 6  + ZEROMIX CFF

 

EXTERNAL RENDERS                    1 : 3 + ZEROMIX CFF
