Modified Micro Silica Gel

Modified Micro Silica Gel Modified Micro Silica Gel (MSG™ code) is a mineral additive that enhances the properties of concrete. Afzir offers a polymer-modified version of micro silica gel, which can be effectively incorporated into all concrete mix designs. This modified micro silica gel is a convenient, one-component, and ready-to-use product that not only improves the concrete’s strength but also enhances its resistance against corrosive chemicals. Additionally, this concrete admixture includes plasticizers that not only enhance concrete flowability but also reduce water consumption. Micro silica gel represents a new advancement in concrete technology, strengthening, and construction. It comprises micro silica powder, plasticizers, and other polymer additives, commonly referred to as micro silica in the industry. The use of micro silica gel in concrete has several significant benefits, such as increased compressive strength, tensile strength, bending strength, durability, lifespan, and impermeability. As a result, this product finds wide application in concrete used for water-intensive environments like ports and beaches, where exposure to water and corrosive substances is high.


PRODUCT DESCRIPTION

Modified Micro Silica Gel is an advanced mineral additive comprising ultra-fine particles of silicon dioxide. With grains smaller than one micron, they are typically 50 to 100 times tinier than cement particles. This unique formulation combines micro silica gel with polymer materials to create a highly versatile and ready-to-use gel product, suitable for all concrete mixing plans.

The modified Micro Silica Gel, known as MSG™ 400, not only enhances the strength of concrete but also significantly improves its resistance to corrosive chemicals. By incorporating softening materials into its formulation, this product not only reduces water consumption during concrete mixing but also enables the production of smoother and more efficient concrete.

The benefits of Modified Micro Silica Gel extend beyond its ability to increase concrete strength and durability. It enhances the overall performance of concrete, resulting in improved compressive strength, tensile strength, and bending strength. This product significantly enhances the durability, lifespan, and impermeability of concrete structures.

Modified Micro Silica Gel is particularly suitable for applications where concrete is exposed to water-intensive environments or corrosive substances. It is highly recommended for use in projects such as ports and beaches, where the concrete structures require enhanced protection against water and corrosive agents.

By incorporating Modified Micro Silica Gel into concrete mix designs, you can ensure superior quality, increased performance, and extended lifespan for your concrete structures. Experience the benefits of this innovative additive and achieve concrete excellence with MSG™ 400 Modified Micro Silica Gel.

Application Instructions

When using Modified Micro Silica Gel, it is important to follow the recommended application instructions. Firstly, determine the appropriate dosage based on the cement weight, typically ranging from 5% to 8%. This ensures the optimal amount of additive is added to the concrete mix to achieve desired results. Secondly, during the mixing process, the Modified Micro Silica Gel can be added to the concrete mixing water. By introducing the additive directly into the water, it can be easily distributed throughout the mix. It is crucial to thoroughly mix the water and additive to ensure uniform dispersion. Additionally, take into account the additional water introduced with the Modified Micro Silica Gel when adjusting the total water content for the concrete mix. Proper adjustment of water content is essential for maintaining the desired workability and consistency of the concrete. Finally, continue with the concrete mixing process, following standard industry practices and guidelines. This includes adding the cement, aggregates, and other components according to the designated mix proportions and mixing sequence. By adhering to these instructions, contractors can effectively incorporate Modified Micro Silica Gel into their concrete mixes and optimize its performance benefits.
