what is glass powder? Glass powder is produced from recycled glass (waste glass ) by grinding recycled glass and granulating it. Glass powder (micronized glass powder) has many applications in various industries, including in glazing, in artificial stone, in composites, in abrasives, in concrete, etc... . We produce all types of glass powder in two sizes from 1 to 100 microns and 100 to 212 microns. contact us to find out glass powder price and how to sell glass powder. The following is a brief description of the applications of glass powder :
1- glass powder in the ceramic and tile industries as the primary material, as well as glass powder in glaze .
2- glass powder as filler in composites .
3- glass powder in cutting with water jet .
4- glass powder in artificial stone .
5- glass powder in concrete. Improvement of the strength and physical and chemical properties of concrete :
If the appropriate percentage (recommended by us) of glass powder under 100 and 212 microns (glass micronized powder) is added to the mixture of concrete or mortar, the characteristics of the concrete or mortar will be corrected as follows:
5-1- Due to the pozzolanic nature of micronized glass powder, Concrete or mortar will have a higher resistance over time. The AAR gel is produced at optimum levels and by creating a dense texture, the final strength of the concrete will be at least 30% higher than the same sample without glass powder. The production of the AAR gel is optimal, causing the closure of the concrete porosity and sealing it. (AAR = Alkali Aggregate Reaction)
5-2- Newly concrete added of micronized glass powder is more adhesive. Increasing adhesion means three cases: - adhesion of the cement paste to the aggregate; - the adhesion of the cement paste to the rods; - the adhesion of the old concrete to the new concrete. Therefore, in cases where high slump is considered, super-lubricant should be added.
5-3- Holds the concrete shrinkage (due to the drying) at the level standard CAS3600 (less than 0.75% in 56 days).
5-4- Microscopic tissue tests indicate that the glass powder can produce a denser mixture and improve the durability and Impermeability of the concrete.
5-5- The use of glass powder in concrete or mortar can prevent the ASR expansion in the presence of active aggregates (ASR = Alkali Silica Reaction).
5-6- Creating anti-wear properties due to the very high hardness of the glass (similar to the diamond) as well as the reduction of concrete porosity.
5-7- The non porosity concrete will be very beautiful and smooth in the facade of the building and will be more durable under atmospheric conditions and sunlight. (Even in the production of concrete blocks)
