The terms with their corresponding definitions are listed below. Indicate those for which the match is correct.
Pot life is the period of time after mixing the mortar mixture necessary to achieve readiness for installation.
Holding time after preparation is the maximum period of time during which a freshly prepared mortar mixture (after additional mixing without adding water) retains its technological properties.
Sliding is the displacement under the influence of gravity of tiles or slabs laid on a layer of mortar mixture treated with a notched trowel applied to a vertical or inclined surface.
A notched trowel is a toothed tool that allows you to create a layer of mortar mixture on the base in the form of grooves of the same thickness.
Open time - the maximum period of time after applying a layer of mortar mixture of a given adhesion strength to the base on the base, during which it is allowed to lay facing tiles on the applied mortar mixture.
Adhesion is the ability of a layer of mortar mixture treated with a notched trowel to wet the facing tile.
Material on this issue is set out in the GOST R 56387 .
The symbol of adhesive mixtures must consist of the name of the mixture in accordance with GOST 31189, class designation, values of basic quality indicators (if necessary) and standard designation. Adhesive mixtures are divided into the following classes...
S1 – highly elastic mixtures
C2 - used for interior and exterior work and meeting increased requirements
S2− elastic adhesive mixtures
T – quick-hardening adhesive mixtures
F – mixtures with extended open time
E – mixtures with increased resistance to slipping
C1 – used for interior and exterior work and meeting the minimum regulated requirements
C0 – used for laying tiles with normal water absorption (at least 5% by weight) only for interior work
