Common problems and treatment of marble pavement

Decoration engineering is an important part of architectural engineering, with the development of society marble gradually entered the decoration market, stone has gradually become one of the indispensable materials for decoration.

Because the construction team technology is generally not high, the construction process generally can not keep up with the development of marble decoration materials, there are still many problems in marble construction, how to prevent and regulate in the decoration construction

The problems emerged, we will analyze the following.

First, analysis

1. Empty drum, falling off:
1) Incorrect proportion of mortar configuration, resulting in excessive mud content;
2) The mortar is not well combined, or the grouting is not solid;
3) A chemical reaction between marble and water in the air causes the marble to fall off and become rough.

2 Cracking:
1) Marble slotting and other factors make the marble structure deformation, resulting in marble cracking;
2) When the marble plate is pressed and deformed, the marble plate surface is subjected to vertical pressure;
3) Marble in the installation, byThe influence of external force, to the marble slab a kind of outward thrust;
4) The marble surface joint is not solid, affected by thermal expansion and contraction, so that the plate cracking.

3. Seam is not uniform, texture is not uniform, color is not uniform;
1) The quality inspection of the plate is not qualified;
2) Try to spell before Mosaic is not serious;
3) The grouting height is too high.

Second, prevention and control measures

1. The prevention and control of empty drum falling off, marble is not also used in the buildings near the industrial zone, varieties should be selected in advance, select pure quality, less impurities, weathering and corrosion resistant marble;Grouting must be full vertical and horizontal joints must be tight.

2. Cracking prevention and control;When inlaying marble slabs, it should be carried out after the settlement of the structure is stable;Cracks caused by the settlement of the structure should be repaired or replaced after settlement is stabilized.

3. Seam uneven surface texture, color and color uneven prevention: check the vertical leveling of the wall and cylinder before mounting, more than the allowable deviation, should be removed or complete;Square the thread before inserting.The selection of marble, specifications and sizes exceeding the deviation should be grinding edge correction;

Marble try to make good color adjustment pattern between the plate and the plate texture smooth.

For marble veneer inserts, in the construction if seriously in strict accordance with the specification, process standards by top to do, will achieve the ideal decorative effect.Only seriously in accordance with the requirements to do, pay attention to the points of construction and installation to prevent marble will not appear problems.
