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.

Environmental Protection Index Special Reminder: Both types of countertops are made of natural materials, and some natural stone materials may be radioactive and emit toxic gases, which does not meet environmental requirements. If not treated with special processes, it may cause harm to human health. Therefore, radiation testing should be conducted when choosing. Stainless steel is a traditional raw material used for household cabinets and kitchen workbenches, usually by adding a thin layer of stainless steel plate on the surface of high-density fireproof board. Advantages: Sturdy, easy to clean, and highly practical. In recent years, due to the strong impact of the new concept of "European and American integration" in modern cabinets, stainless steel countertops have also been improved in line with the development trend of combining aesthetics and practicality of cabinets.

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.

 
Scientists have found a solution to the problem of sound insulation in rooms, making our homes more peaceful. American aerospace engineering professor Krechan? Ahgar has developed an anti noise material composed of many hollow plastic balls with many tiny holes, which can eliminate any noise emitted from dishwashers to various fans. Different from traditional sound insulation materials (such as foam materials, glass fiber, etc.), this kind of sphere with a diameter of 1-5mm can be poured into building materials (such as walls) to make noise. When sound waves hit a tightly wrapped sphere and move around it, it causes the ball to vibrate and transform into different, inaudible frequencies.

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

The main types of marble in Egypt include golden, dark, golden beige, steel beige, Bi Li Xia, Sinai pearl, Arabastal, golden beige, rose silk, Jade Emperor pearl, Sahara beige, Jade Emperor beige, golden beige, new sago, etc., all of which are highly valued and widely used stone varieties. The production capacity of Egypt's stone industry: Mining capacity: 320000 tons/year, sawing capacity: 180000 square meters/year, grinding capacity: 120000 square meters/year. The current problem in Egypt's stone industry is the lack of funds. Egyptian stone companies generally have low capital accumulation, due to the fact that local stone companies in Egypt have long relied on a single product variety, low product value, small enterprise scale, and lack of deep processing capabilities for stone.

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

In modern housing construction, bay windows are commonly designed in residential buildings, which is loved by the public. With the popularity of the public, this area has also become a key focus of decoration. When decorating bay windows, everyone likes to choose high-end stone paving, among which bay window marble is a commonly used type. The advantage of bay window marble is that it can provide a good brightness for one's home. This way, the emission of marble can make the room bright, and the bay window made of marble stone is not easy to fade and can maintain its original brightness continuously. What should we pay attention to when laying marble on bay windows in order to make the entire decoration flawless? There are four main points to note: unevenness and straightness of multiple spliced bay window panels; excessive deviation in length and width of processed bay window panels, and inconsistent thickness.

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, when quartz stone is jointed, washing the joint with a water bottle will have a better effect. The front water blocking effect is very similar to that of a hill stone, but slightly inferior in terms of curvature. Relatively speaking, it is easier and more effective to polish and polish granite. It's just that the duration of use won't be too long. Installation: Gangshi is faster and quartz dust is relatively less. Now when installing quartz stone countertops, extra subsidies must be given to the master. Because the quartz stone is too heavy, it requires on-site water blocking, edge grinding, and opening of furnace holes, which will take longer. Plate surface analysis: Quartz stone generally has transparent or semi transparent particles, which is due to the fact that the main component of quartz stone is quartz crystal; And the granite is mostly opaque particles, mainly composed of acrylic and natural stone powder; Generally, the thickness of quartz stone is around 15 centimeters, while the thickness of granite is around 11-12 centimeters.

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.

For some homeowners and construction workers, although they applied protective agents to the marble in advance, there were still problems when it was laid on the ground. This is partly due to the cracks and loose parts of the stone not being well repaired, and the large water pressure on the back of the stone quickly destroyed it due to moisture. On the other hand, although the front of the marble is also protected, the moisture on the ground will also enter the interior of the stone through cracks and loose parts, increasing the humidity of the stone and forming a vicious cycle; The settlement and tearing of the foundation part of the ground lead to the cracking and damage of the ground stone; From the perspective of stone quality, choosing marble to lay the ground has left behind a problem: on the one hand, people often only focus on color tone when choosing stone, without considering the differences in weather resistance and wear resistance between marble and granite.
