Investigation of the Moisture Condition of the Outer Wall at the Junction of the Brick Pilasters to the Wall

The analysis of the moisture state of the zone of adjacency of the brick pilaster to the wall during its insulation from the inside is performed in this research. Brick pilaster is made of slotted ceramic bricks. The influence of filling the cavities of the slotted brick with cement-sand mortar on the moisture state of the adjacency zone was considered. The moisture state at the incomplete filling of the seam between the pilaster and the wall with cement-sand mortar is considered. The conditions of the beginning of the moisture condensation on the surface of the seam that is not filled with mortar are detected. The variant of a seam filling, in the case of which the condensation zone is the greatest, is revealed. The reasons for the detachment of the pilasters from the wall were identified. The influence of internal insulation on the formation of condensation and ice in the zone of adjacency of the pilaster to the wall is revealed. Methods of improving the moisture condition and eliminating the identifying shortcomings are proposed.
