Grouting construction

Basic processing

1. Clean the surface of the foundation without any debris such as crushed stones, floating slurry, floating ash, oil stains, and release agents.

2. 24 hours before grouting, the foundation surface should be fully wetted, and 1 hour before grouting, any accumulated water should be removed.

There are many types of patterns that tend to be straight in stone products, and they should be used reasonably It is helpful to improve the aesthetic beauty of the decorative surface. The utilization of horizontal patterns in stone finishes: In the design of floor finishes, if the pattern is oriented along the length of the ground, the ground will show a sense of depth; If the direction of the pattern is perpendicular to the length direction of the ground (used horizontally), the ground will appear wide; If the ground is divided into grids using dimensions suitable for spatial division, not only will it have the decorative effect mentioned above, but it will also increase the variability effect. When designing wall finishes, using straight line patterns as horizontal extensions can create a sense of tranquility, smoothness, and reduce the height of the space.

1. Set up templates according to the grouting construction drawing. The joints between templates and foundations, as well as between templates, shall be sealed with cement slurry, tape, etc. to achieve the degree of overall template waterproofing.

2. The horizontal distance between the template and the equipment base should be controlled at around 100mm to facilitate grouting construction.

3. The top elevation of the template should be 50mm higher than the surface of the equipment base.

4. If there is grout leakage during grouting, it should be dealt with in a timely manner.

 
In people's minds, it is often believed that stone is a long-lasting decorative material, and using stone for decoration can solve the problem once and for all. However, this is not the case. In the natural environment, dust, exhaust gas, rain, freezing, and other pollutants can easily cause fading, pollution, and even damage to the stone used in buildings, greatly reducing the decorative effect and service life of the stone. At the same time, due to errors in construction methods, the decorative effect of the stone can also fail, forcing the building to be renovated in a short period of time, resulting in a significant waste of manpower and resources. The transformation of stone comes from two aspects: one is natural reaction generation. Because the material composition inside the stone contains hematite and iron ore, these iron minerals are oxidized by air to form iron oxide (rust), which seeps out through the capillary pores of the stone; Secondly, during the processes of mining, processing, transportation, installation, and use, stone inevitably comes into contact with iron objects. The residues of these iron objects adhere to the surface of the stone and are oxidized to form rust pollution.

Step 3: Preparation of grouting material

1. The general reinforced type is mixed with water at a standard of 12-13%, while the pea gravel reinforced type is mixed with water at a standard of 9-10%.

2. It is recommended to use mechanical stirring method, and the stirring time is generally 1-2 minutes. When using manual mixing, 2/3 of the water should be added first and mixed for 2 minutes, then the remaining water should be added and mixed evenly

Marble has gradually gained favor from the decoration industry and customers due to its natural material and diverse colors and patterns. Marble manufacturers across the country occupy a small portion of the stone market, and their competition is very fierce. In this environment where the market forces manufacturers to do everything possible to reduce costs, in addition to putting effort into management, the mechanical equipment and processing technology are similar. Therefore, a new technology and product with disguised thinking have emerged. Save costs in terms of resources, from 1m2 to 3m2 or even 4m2.

3. The amount of mixing each time should be determined based on the amount used to ensure that the material is used up within 30 minutes.

4. During on-site use, it is strictly prohibited to add any admixtures or external additives to the grouting material.

Step 4: Grouting Construction Method

1. Long equipment or track foundations should be constructed in sections.

2. During secondary grouting, grouting should be carried out from multiple points on one side or adjacent sides until it overflows from the other side, in order to facilitate exhaust during the grouting process. Grouting shall not be carried out simultaneously from all four sides

For areas where negative temperatures may occur, freeze-thaw tests are also required. It can only be used when all performance indicators meet the design and specification requirements. Control the processing accuracy of stone and avoid secondary cutting at the construction site. Due to the influence of installation technology, the commonly used stone dry hanging technology now requires drilling or slotting on the cross-section of the stone board. Therefore, the thickness of the stone is limited by the installation technology, and a structural thickness must be ensured. Therefore, special attention should be paid to the thickness of the board during the acceptance of the stone board process, with a allowable deviation of+2 millimeters and no negative deviation allowed. It is necessary to inspect each piece. To avoid damage during mining, transportation, cutting, and installation, once the stone has become a sheet and is collided, the damage, especially internal damage, is difficult to detect. However, it will develop over time and in severe cases, it may break, posing a safety hazard.

3. After grouting begins, it must be carried out continuously without interruption. And shorten the grouting time as much as possible.

4. Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster can be used to push the grouting material along the bottom of the grouting layer. It is strictly prohibited to push it from the middle or upper part of the grouting layer to ensure its uniformity.

5. After the equipment foundation grouting is completed, a 45 degree oblique angle should be cut outward along the edge of the equipment 3-6 hours after grouting to prevent cracks from forming at the free end. If edge cutting is not possible, the surface of the grouting layer should be smoothed with a trowel 3-6 hours after grouting.

6. The thickness of each grouting material should not exceed 100mm.

Generally speaking, the waterproofing problem of external insulation surfaces can be solved by using polymer specific mortar and flexible putty; However, there is a great deal of controversy in the academic and application circles regarding the issue of vapor permeability. A typical statement is that materials such as XPS board are not vapor permeable and are not suitable as the main material for external insulation. In fact, there are few successful cases in implemented projects. The so-called steam permeability of the exterior wall actually refers to the diffusion ability of water vapor to migrate from the high temperature side to the low temperature side. For composite building structures, with the insulation layer as the boundary, the author believes that if the sum of the water vapor permeability resistance between the exterior wall and the insulation layer is greater (and the larger the better) than the sum of the plaster layer and the decorative layer, in winter, the water that enters the wall through diffusion can be easily discharged outside. Otherwise, condensation will occur at the junction of the insulation layer and the plaster layer, causing freeze-thaw damage.

7. When the grouting volume of the equipment foundation is large, the mixing of pea gravel reinforced grouting material should be done by mechanical mixing to ensure grouting construction.

Step 5: Maintenance

1. Within 30 minutes after grouting is completed, a wet grass curtain or rock wool blanket should be immediately covered and kept moist.

2. During winter construction, maintenance measures should also comply with the relevant provisions of the current GB50204 standard.

3. After the grouting material reaches the demoulding time, equipment installation can be carried out. For specific time, please refer to the "Relationship Table between Demoulding and Curing Time and Environmental Temperature".

4. After the grouting of the equipment foundation is completed, if any parts need to be removed, they can be gently removed with a spatula or shovel tool 3-6 hours after the grouting is completed, before the grouting layer hardens.

5. The vibration of the running machine should not be transmitted to the equipment foundation. After the secondary grouting, the machine should be stopped for 24-36 hours to avoid damaging the uncured grouting layer.
