Q:Natural marble and man-made stone do kitchen table which is good?

Natural stone Natural stone is divided into two types: marble and granite. In general, there is a texture, called "marble"; to spot the main, called "granite." This is in a broad sense. From the narrow sense, the marble refers to the marble produced in Yunnan Dali. In fact, now the country is not much stone is Dali out. The two can also be distinguished from the geological concept. Granite is igneous rock, also known as acid crystal deep diagenesis, is the most widely distributed igneous rock, composed of feldspar, quartz and mica, rock hard and dense. Its composition to silica-based, accounting for about 65% -75%.

Q:Can a waterproofing membrane be used on tunnels with ventilation systems?

Tunnels with ventilation systems can indeed utilize a waterproofing membrane. It is highly advisable to incorporate such membranes in these tunnels to avoid water infiltration and potential harm to the tunnel structure and ventilation system. The presence of a waterproofing membrane will establish a barrier that hinders water from seeping into the tunnel, thereby preserving its integrity and shielding the ventilation system from water-related problems like corrosion or moisture accumulation. Moreover, the use of a waterproofing membrane can aid in upholding the efficiency and effectiveness of the ventilation system by preventing moisture or water vapor from entering the tunnel, which could lead to condensation or the growth of mold. All in all, incorporating a waterproofing membrane in tunnels with ventilation systems is a vital measure in guaranteeing the long-term durability and functionality of both the tunnel and its associated ventilation system.

Q:How do earthwork products contribute to slope stabilization and erosion control on highways?

Earthwork products, such as geotextiles, geogrids, and erosion control blankets, play a vital role in slope stabilization and erosion control on highways. These products are designed to enhance the stability of slopes and prevent erosion by providing a barrier against soil movement and water flow. Geotextiles offer reinforcement and filtration properties, improving soil strength and allowing water to drain, reducing the risk of landslides and erosion. Geogrids provide additional strength to soil structures, increasing their stability and resistance to slope failure. Erosion control blankets protect exposed surfaces from erosion caused by rainfall and wind, promoting vegetation growth and reducing sediment runoff. Overall, these earthwork products are essential in ensuring the safety and longevity of highways by effectively managing slope stability and preventing erosion.

Q:Can geogrids be used in reinforcement of underground tunnels and caverns?

Yes, geogrids can be used in the reinforcement of underground tunnels and caverns. Geogrids are commonly used in geotechnical engineering applications to improve soil stability and provide reinforcement. They can be installed as a reinforcement layer within the tunnel or cavern walls to enhance their structural integrity and prevent potential collapses or deformations. The geogrids act as a reinforcement material, distributing the loads and increasing the overall strength of the underground structures.

Q:Home decoration, please curtain wall with aluminum plate how much the price per flat

According to my knowledge, I say ~ aluminum-plastic composite board is a chemically treated aluminum plate for the surface material, with polyethylene plastic as the core material, in the special aluminum-plastic plate production equipment from the processing of composite materials The The unique performance of the aluminum-plastic composite panel itself determines its wide range of uses: it can be used for building facades, curtain wall panels, retrofits of old buildings, interior walls and ceilings, advertising signs, display stands, engineering. Aluminum-plastic composite panels in the country has been widely used, belonging to a new type of building decoration materials. I know that the general price is between 80 to 120 yuan This is what I know the information, I hope you have a reference role ~

Q:My car was thrown in the thirty thirties this year, driving the lock of the lock heart are pry rotten, but did not pry open, the door handle is also deformed, I bought a full security, but the insurance company said this is Do not lose, that unless it was stolen was lost, steal the loss caused by the loss, which is right? The The I am Nissan Tiida hatchback, do not know this is to change the car or only a lock on the line, about how much money? The The The Thank you ~~~~~~ Thanks! More

Insurance company is right, because you are on the whole car Daoqiang Xian, insurance is just the insurance company launched the existing insurance, not what are lost! A lock is broken, the whole car lock should be changed, more than 2000!

Q:We need to renovate the engine room, the general number of space is appropriate?

three hundred to filve hundred

Q:Are geogrids suitable for use in road widening projects?

Yes, geogrids are suitable for use in road widening projects. Geogrids are commonly used in road construction and rehabilitation projects to improve the stability and strength of the road base. They provide reinforcement by distributing loads and reducing stress on the road surface, making them an ideal solution for road widening projects where additional support is required.

Q:The curtain wall of the three Tu a roast what it means

Fluorocarbon spraying process is: ? Pre-treatment process: aluminum to the oil decontamination → washing → washing (degreasing) → washing → pickling → washing → chrome → washing → pure water ? Spraying process: spray primer → finish → varnish → baking (180-250 ℃) → quality inspection ? Multi-layer spraying process to three spray (referred to as three spray), spray the bottom paint, finish and varnish and secondary spray (primer, finish).

Q:Is the bottom floor of an apartment building considered a story? You know, a "three-story building," etc.

As long as it's not considered a basement apartment, then it is the first story. Also called ground floor. A garden apartment is usually halfway underground and halfway above ground. I honestly don't know if they are considered basement or 1st floor since they are a bit of both.
