Concrete and reinforced concrete are the largest and most important construction engineering materials in use today, and one of the most durable materials in construction today. However, due to the corrosion of the environmental media where the building is located and the design, construction and use of many factors, both concrete and reinforced concrete structures are subject to various degrees of corrosive media corrosion damage, which directly affects the durability of the concrete structure. The reduction of the basic performance of concrete strength and its bond strength with steel bar reduces the safety of the structure and causes great losses to the development of the national economy and safe production.
The durability problem of concrete structure is more complicated, and the more common damage factors are: freeze-thaw cycle, steel corrosion, carbonation, fresh water dissolution, salt corrosion, alkali-aggregate reaction, acid-alkali corrosion, impact , Wear and other mechanical damage.
Concrete durability testing technology has also been rapidly promoted with the development of durability research. Starting from several mechanisms that affect the durability of concrete, this program introduces the related aspects of concrete durability research and testing equipment, aiming to better provide supporting solutions for test instruments for concrete durability laboratories in different industries, which is more economical Effectively solve the durability problem of concrete faced in scientific research and engineering examples.

Lip gloss:
1. Lip gloss can moisturize lips.
2. Lip gloss can play the role of decorating lips, making people look more colorful.
The difference between lip gloss and Lipstick:
1. The effect of lip gloss is more distinct and unique. Lipstick is low-key, generally used to moisturize lips, and its color is lighter.
2. The color of lip gloss is brighter and more changeable than that of traditional lipstick, but its durability is not as good as that of lipstick.
3. Lip gloss is rich in various highly moisturizing oils and glittering factors, which is bright, transparent, light and moisturized, and makes lips moist and three-dimensional after coloring. Lipstick has high color saturation and strong color hiding power. It is generally used to modify lip shape and color.
