Mortar hollowing problem

By |2024-04-10T08:24:48+00:00April 10th, 2024|Industry knowledge|

Mortar hollowing problem 1. Hollowing of mortar on shear walls often occurs on construction sites. The fundamental reason why shear wall mortar is prone to hollowing is that the dry hard shrinkage rates of the concrete layer and the mortar layer are inconsistent, resulting in shrinkage stress. If the shrinkage stress is too concentrated at

How to treat alkali return on walls? Surface return to base If there is a back-alkali reaction only on the surface, it is because the various substances in the material have poor density and are easy to absorb moisture. When the material contains chemically unstable alkaline impurities exceeding the specified value (marble and most tiles

What is wall alkali return? How to prevent?

By |2023-12-12T06:26:27+00:00December 12th, 2023|Industry knowledge|

What is wall alkali return? Alkali return of the wall means that after the building wall becomes damp. The moisture dissolves the alkaline substances in the wall into the water. And as the water vapor evaporates. The alkaline dissolved matter is brought to the surface of the wall and crystallizes and solidifies on the surface
