Microsilica concrete additive Clinic Beton Iran

Microsilica powder or microsilica powder to strengthen the sealing properties and durability of concrete structures, especially in coastal structures, water structures and concretes that are exposed to severe attack of sulfates and corrosion of reinforcements. The use of microsilica in concreting near the coasts of the seas has recently attracted the attention of construction engineers due to the distinct pozzolanic properties of microsilica, its use to improve the mechanical properties and increase the durability of concrete is increasing in developed countries. Micro-silica is a by-product of electric arc furnaces during the production of ferro-silica alloys. Having more than 90% of silica in a non-crystalline state and in the form of infinitesimal particles with an average diameter of 0.1 micron, it is highly pozzolanic and is very suitable for use as a cementitious material in concrete and complies with the ASTM C1240 standard.

Performance of Microsilica concrete additive:

Adding microsilica to the concrete mixture causes its active SiO2 to combine with calcium hydroxide solution (OH) in the capillary pores of the concrete and produce insoluble calcium silicate crystals, and ultimately causes the compaction of the cement paste structure, reducing permeability and increasing compressive strength. , electrical, bending and tensile properties of concrete, increasing the resistance of concrete against erosion, decreasing permeability, preventing the penetration of chlorine ions, sulfates and other destructive chemicals into concrete.

Applications of Microsilica concrete additive:

• Execution of concrete on sea shores, docks and bridges
• Construction of high strength concrete
• Concrete construction of dams, canals, tunnels, reservoirs and water sources
• Flooring and facade construction
• Construction of corrosion-prone concretes

Microsilica concrete additive consumption amount:

In order to use the microsilica concrete additive, Microsilica can be added to concrete at a ratio of 3 to 7% of the weight of cement (considering that it increases the strength of concrete and replaces the same amount of cement), considering that microsilica has the property of reducing water. It should be used together with one of the concrete super-lubricants. Otherwise, it will cause the concrete to crack and reduce the efficiency and lack of concrete compaction.

Method of using Microsilica concrete additive:

When making concrete, mix with dry ingredients as much as necessary and then add water and superplasticizer to it.

Physical and chemical characteristics of Microsilica concrete additive:

• Physical state: pozzolan powder
• Color: light gray
• Specific weight: 250 grams per cubic centimeter
• Particle shape: spherical and non-crystalline (amorphous)

Microsilica concrete additive storage method:

Microsilica can be stored away from cold, heat and moisture for one year. Not paying attention to the proper storage method will damage the product or its bag.

Microsilica concrete additive packaging:

Microsilica concrete additive is packed in 25 and 40 kg bags or 1 ton jumbo bags.

Microsilica concrete additive protection and safety:

As with all chemical products, be careful to avoid contact with eyes, mouth, skin and food. In case of contact with skin and eyes, immediately wash it with water for 15 minutes and consult a doctor. If accidentally swallowed, medical measures should be taken. Close the containers after use and refer to the product safety brochure for information on special storage or disposal of remaining materials.

Purchase and price of Microsilica concrete additive, Iran concrete clinic

Making the market is a database and a network of manufacturers and suppliers of construction products that introduces companies and specialized reviews of construction products. The general purpose of building a market is to establish a direct relationship between the buyer and the producer. Dear buyers, to know the price of other concrete additives, refer to the market building system and buy Microsilica concrete additive from reputable sellers.

Manufacturers and suppliers can register in the market construction system and participate in the special sales festival by placing construction products and inserting the suggested price and increase the sale of their products.
