5 thoughts on “Why don't Haisha use it for architecture”

The reason why sea sand is not used for construction: Since the sea sand contains chlorine ion, if this ingredient is exceeded, it will have a serious corrosion effect on the steel bars after stirring through the concrete. Because sea sand contains natural salt, it has strong corrosiveness. Cement stirred with sea and sand will rust the reinforcement in less than 5 years. Use sea sand to stir concrete and pour the building. The steel bars in the concrete will slowly be oxidized by the salt of the sea sand, causing prestressing, decreased strength, hardness, and tolerance, which will seriously affect the service life of the building. The wall and ground with sea and sand brushes will cause serious humidity. When you encounter the southeast wind or plum rain season, the wall will exudate a large amount of water droplets and water droplets. The human body brings joint pain. In addition, no matter how soaking the salt in Haisha, its salt cannot be washed off. Extension information:
Ilains:
1, industry. Industrial sea sand can be divided into silicon sand, calcium sand and heavy sand in terms of composition. Although the output only accounts for 10 % of the total use of the total sea sand, the use is extremely wide. 2, ironmaking. Iron sea sand, obtained by magnetic selection. Used for ironmaking and steelmaking. Such as Indonesia Hai Sand. 3, glass manufacturing. Glass sand is the main raw material for manufacturing glass. Its granularity specifications can refer to the standards of the American Ceramics Society, while the ingredients depend on the type of finished product and have different specifications. In terms of optical glass with the highest purity, the siliconic silicon oxide content must be greater than 99.8%, and the content of alumina and iron oxide must be less than 0.1% and 0.02%, respectively.

Sea sand is rich in salt (chloride ions). When the chlorine ion content in the concrete exceeds the critical value, chloride ions will produce a chemical reaction with the reinforcement. Because the sea sand contains chlorine ions, the white stains will exudes the wall in the short term, commonly known as wall cancer. Star houses have only 6 to 10 years of use. There are currently two methods for anti -corrosion. One is the cathode anti -corrosion method, and the other is the electrochemical salt removal method to reduce the speed of steel corrosion to extend the life life of the house. Therefore, sea and sand are often used in sports sand and family garden landscapes, while building sand is usually river sand. The building cannot be used as a concrete raw material, otherwise a large number of buildings will appear. Pucting information: It sea sand use 1. Glass sand is the main raw material for manufacturing glass. Its granularity specification can refer to the standard of the American Ceramics Society, while the ingredients depend on the type of finished product and different. specification. In terms of optical glass with the highest purity, the siliconic silicon oxide content must be greater than 99.8 %, and the content of alumina and iron oxide must be less than 0.1 % and 0.02 %, respectively. 2, cast sand is used to make steel and cast copper, lead, iron alloy. The characteristics of silicon sand include adhesion, insulation and permeability. 3, heating sand is often used as raw materials for making silicon bricks and tiles. 4, the scrub is mainly composed of quartz sand, used for sawstones, glass polishing, metal polishing and sandblasting. Demand characteristics include cleaning, hardness, consistent particle size, and edges.

Because sea sand contains a high salt amount and the chlorine ion exceeds the standard, the sea sand has strong corrosiveness, so it not only damages the concrete itself, but also destroys the steel bars passivation film and corrodes the reinforcement. The building life of Haisha is half less than normal buildings, causing many buildings to show up mottled steel bars. Therefore, sea and sand are often used in sports sand and family garden landscapes, while building sand is usually river sand. In the building, sea sand cannot be used as concrete raw materials, otherwise a large number of buildings will appear crispy. The Ministry of Construction pointed out in the management regulations of the construction of the building that sea sand must be used after purification treatment and meets the requirements. For reinforced concrete, the content of chloride ions in the sea sand in the sea sand should not be greater than 0.06%.
Why do the building high -rise buildings prefer to dig river sand and Haisha, and do not want to move the sand in the desert?

1. For prime concrete, the content of chloride ion in the sea sand does not restrict; 2. For reinforced concrete, the chlorine ion content in the sea sand should not be greater than 0.06 % (percentage measurement at the weight of dry sand) r 3. Sea sand should not be used for prestressed concrete. If sea sand must be used, its chlorine ion content must not be greater than 0.02 %. The testing methods for chloride ion content in sand are stipulated in the industry standard of the Ministry of Construction "General Sand quality standards and inspection methods" (JGJ52-92). The simple way to reduce the content of chloride in the sand is to rinse with fresh water. Maisha can be used in masonry engineering and plastering projects without reinforced or steel -buried parts.
