Details

EVERBUILD MORTAR ADMIX is an air entraining liquid plasticising admixture which forms extremely stable air bubbles in mortar mixes. The admix improves workability and freeze/thaw resistance in brick laying mortars, reduces the need for lime and smoothes out variations between separate batches of sand and cement. Conforms to BSEN934- Part 3 (2009)

 

Benefits

  • Outperforms traditional Vinsol Resin Based plasticisers (See specific data)
  • Contains a special additive which keeps air in the mix longer than most other competitive admixtures.
  • Improves trowelability.
  • Easier tamping down and alignment.
  • Improves workability.
  • Provides resistance to freeze/thaw cycling down to -2oC in both wet and dry mortar.
  • Chloride free (chloride ion content <0.1%).
  • Reduces bleeding.
  • Replaces lime in mix, hence reduces possibility of lime bloom and efflorescence.     

 

Areas For Use

Load bearing brickwork

Block laying

External/Internal rendering

Pointing/repointing brickwork.      

 

Application

In all cases, add to mix at an addition rate of 150ml to 250ml per 50kg cement, depending on the degree of plasticising/entrainment required. Note: remember to reduce required quantity of water accordingly. One litre of MORTAR ADMIX added to a 200ltr drum of gauging water will be sufficient for gauging approx. 4 x 50kg cement for mortar or render mixes. Whilst overdosing should be avoided, this formulation does safeguard against moderate overdosing.  (Up to double the maximum rate).

                             

The following are examples of modified mix designs.

 

1: 0.25 :3  cement : lime : sand.                                1:1:6 cement : lime : sand.

use 1 : 3  cement : sand : + MORTAR ADMIX:   use 1 : 6  cement : sand + MORTAR ADMIX

 

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

 

INTERNAL RENDERS          1 : 6  + MORTAR ADMIX

 

EXTERNAL RENDERS                    1 : 3 + MORTAR ADMIX

Extra tests were carried out in over and above those required by BS4887, to simulate more effectively actual performance requirements in site conditions. One such comparative test is shown below, which simulates the actual loss of air form a mortar mix due to vibration when transferred to site.
