What is UGGBS

Pyramid Industry PVT. LTD is a cutting-edge cementitious Material manufacturing company with an ambition to establish itself as a leading player in the industry to serve quality product. Nowadays due to vertical growth & rise in construction industry high strength concrete has gained immense popularity. In recent years the application of high strength concrete have increased in many fold, and high strength concrete has now been practicable as a result of recent development in construction industries, material technology and demand for higher-strength or high performance concrete.

Pyramid Buildfine performs in superior manner when used in concrete. Due to its inbuilt low Ca0 – Si02 content it has two way reactions during hydration: Primary reaction of cement hydration and pozzolanic reaction in which it consumes by product of calcium hydroxide from hydration of cement to form calcium silicate hydrate (CSH) gel similar to pozzolanas.

C3S +H2O =C-S-H +CaOH2

siO2 +CaOH2 = C-S-H

Pyramid Buildfine is a low calcium silicate mineral based admixture which is controlled for its narrow range particles size distribution to achieve the high levels of reactivity. Fineness and high reactivity of Pyramid Pyramidattributes to enhance hydration process. Addition of Pyramid Pyramidimproves the particles packing of paste a component which ultimately leads to concrete with higher strength and improved durability. Pyramid Buildfine durability parameters and strength of M100and above is possible to achieve.

How Pyramid Buildfine Work

Pyramid Buildfine work in three ways

Primary hydration reaction attributed to inbuilt CoO
Secondly, pozzlolanic reaction that converts un-reacted calciumhydroxide into C-S-H crystal structure.
With average practical size less than6 micron and uniform distribution of particles ensures a densely packed matrix.

Low Void in Structure

UGGBS contributes to low void formation within structures. This characteristic ensures a denser and more durable construction, reducing the likelihood of structural flaws and enhancing the overall strength and longevity of the project.

Low Penetration

With UGGBS, structures benefit from low penetration, offering increased resistance to the intrusion of harmful substances. This advantage enhances the durability and lifespan of the construction.

No Bleeding, No Segregation

Pyramid Company's Ultrafine Ground Granulated Blast-furnace Slag ensures concrete with exceptional flowability, eliminating the risk of bleeding and segregation during placement.

Advantages of UGGBS

High Chemical Resistivity

UGGBS imparts a high degree of chemical resistance to structures. This key advantage ensures resilience against corrosive elements, making it an excellent choice for projects in environments where chemical exposure is a concern.

Low Water Usage

This not only contributes to the conservation of resources but also enhances the strength and performance of the concrete, resulting in more sustainable construction practices.

Low Thermal Cracking

This advantage is particularly beneficial in regions with varying temperature conditions, ensuring the longevity and structural integrity of the construction by mitigating the risk of thermal stress-induced cracks.

Technical Benefits

Use of Pyramid Buildfine will directly lead of following technical advantages.

Better Workability
Avoids segregation/Bleeding
Retention of Longer workability
