Specification
Trowel ready building and plastering mortar complies with BS EN 998-1 Standards. Sampling and testing are carried out on a regular basis, internally by CES Quarry Products Ltd and a qualified external contractor, ensuring only the highest quality Mortar.
Site mixed mortar for residential dwellings.
Designated 2 mortar is recommended for below DPC crushing at 4.5n
Designated 3 mortar is recommended for above DPC crushing at 2.5n
Your typical site mixed mortar mixed at a ratio of 5-1, made into a cube will crush at approximately 7n, ok for footings but at least 3 times the strength needed for the super structure.
If you take into account the calculation that if you crushed the mortar placing it between 2 blocks considerable more than 7n would be achieved.
The excessive strength of your site mixed mortar will increase the lightly hood of cracks.
Using on Site
As our mortar is ready to use, nothing should be added on site. The mortar should be kept covered in the tub when it is not being used to reduce evaporation, contamination by site dust and to prevent rain from diluting the mix.
The mortar should not be remixed with water on site after it has started to set or used frozen. Saturated blocks or brick should not be used. The Mortar tubs should be clean prior to filling.
Mortar Setting Time
CES mortar contains a retarder to prevent setting in the mortar tub for 36 hours. When the mortar is built into the wall, setting takes place as the moisture is drawn into the block or brick and by surface drying.
Good building practice should be followed, taking into consideration the speed of moisture loss into the brick or block and into the air, so that normal setting has a chance to take place before the wall is built too high. Freshly built walls should be protected from rain.
Reduced Efflorescence
The air entraining agent in the trowel ready mortar improves the plasticity of the mortar, eliminating the need for lime. This reduces the possibility of efflorescence on the finished wall.
