Concrete is one of the most common building materials in the construction field, and its superior compressive strength and durability make it the first choice for all types of construction projects. However, quartz sand is gradually emerging in the pursuit of higher performance and longer-life building materials. This article will discuss the application of quartz sand in concrete, and how it can improve the strength and durability of concrete.
Properties of quartz sand.
Quartz sand is an extremely hard ore, and its main component is silica. In contrast, traditional river or sea sand may contain organic impurities, salts, etc., which can adversely affect the strength and durability of concrete. Quartz sand, on the other hand, is favored for its pure composition.
Quartz sand has properties such as hardness, wear resistance, and compression resistance, which makes it an ideal filler in concrete. In addition, the uniform distribution of particles between quartz sand particles helps to improve the compactness of the concrete, thereby improving its compressive strength.
Improve the compressive strength of concrete.
Increase the density of the pellet filling.
The uniform distribution and hardness of quartz sand particles allow it to fill the voids more tightly in the concrete, which improves the compactness of the concrete. High compactness is one of the important factors of concrete compressive strength, and the introduction of quartz sand makes the particle filling density of concrete higher and the compressive strength is also improved accordingly.
Reduces the occurrence of shrinkage cracks.
Concrete shrinks during the hardening process, which can lead to the formation of cracks, which reduces the strength and durability of the concrete. The use of quartz sand helps to slow down the shrinkage rate of concrete, reduce the occurrence of shrinkage cracks, and then improve the overall compressive capacity of concrete.
Improve the durability of concrete.
Erosion resistance.
The hardness and wear resistance of quartz sand make concrete more resistant to erosion. In some special environments, such as seawater erosion, chemical erosion, etc., traditional sandy soils may be eroded and lose their original strength. The use of quartz sand can effectively enhance the erosion resistance of concrete and prolong its service life.
Improves durability.
The application of quartz sand in concrete can also effectively improve the durability of concrete. Due to its pure composition and hard properties, quartz sand makes concrete more resistant to erosion by time, natural factors and environmental influences. This increased durability makes the building structure more durable, reduces the frequency of maintenance and repairs, and lowers the cost of ownership. Of course, if you also need quartz stone, you can take a look at Chifeng Hengyuan Mineral Products*** Their products are exported to overseas, Malaysia, Italy, South Korea, Japan and other countries, specializing in the production and sales of mineral products.
As a filler in concrete, quartz sand gives higher compressive strength and durability to concrete through its hard, wear-resistant, and compressive properties. In the field of construction, the pursuit of more durable and safe building structures is an eternal goal, and the application of quartz sand provides us with an effective way. Beyond the traditional sand, the introduction of quartz sand will bring new possibilities for the development of building materials, and provide a more reliable guarantee for the strength and durability of future buildings.
