Benefits of G-Chem Microsilica in Concrete Aditive Longer service life:G-Chem Microfine is a highly reactive pozzolan and gives concrete a denser Microstructure, Lower Permeability & Higher Electrical Resistivity leading to improved durability.The durability of a reinforced concrete structure can be defined as the capability of the structure to maintain its original functional and structural characteristics during the expected service life in the exposure conditions it was intended for.
Combined with correct design and workmanship, Micro silica concrete offers characteristics that will ensure long term durability and service life.
Higher strength concreteG-Chem Microfine is used to make the high strength concrete that is often essential in major projects, such as record breaking tall buildings, Roads and Bridge.These engineering applications requiring high strength concrete use microsilica as a cost effective means to increase compressive strength. Ultra-high strength concrete (UHSC), typically defined as >150MPa can be achieved using higher dosages of G-chem Microfine Increased strength results from Micro silicas particle packing & pozzolanic reaction. In Micro Silica concrete, the thickness of the transition zone (interface) between the cementitious paste and aggregate is reduced and the CH crystals are smaller and more randomly oriented, resulting in decreased porosity & increased interface bonding strength.

Silica fume, also known as micro silica is silicon dioxide, silica. It is an ultrafine powder collected as a by-product of the silicon and ferrosilicon alloy productionThe main field of application is as pozzolanic material for high performance concrete.

Technical Specifications:

• SiO2 - Silica : >90%
• Color : Grey 

Application

Because of its extreme fineness and high silica content, silica fume is a very effective pozzolanic material. Standard specifications for silica fume used in cementitious mixtures are ASTM C1240,[8] EN 13263.[9]

Silica fume is added to cement concrete to improve its properties, in particular its compressive strength, bond strength, and abrasion resistance. These improvements stem from both the mechanical improvements resulting from addition of a very fine powder to the cement paste mix as well as from the pozzolanic reactions between the silica fume and free calcium hydroxide in the paste.

Addition of silica fume also reduces the permeability of concrete to chloride ions, which protects the reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those of humid continental roadways and runways (because of the use of deicing salts) and saltwater bridges.

Effects of silica fume on different properties of fresh and hardened concrete include

a) Workability: With the addition of silica fume, the slump loss with time is directly proportional to increase in the silica fume content due to the introduction of large surface area in the concrete mix by its addition. Although the slump decreases, the mix remains highly cohesive.

b) Segregation and bleeding: Silica fume reduces bleeding significantly because the free water is consumed in wetting of the large surface area of the silica fume and hence the free water left in the mix for bleeding also decreases. Silica fume also blocks the pores in the fresh concrete so water within the concrete is not allowed to come to the surface.

Application Areas:

• High performance concrete
• High strength, low permeability concrete
• Industrial flooring
• Water tanks and sumps
• Chemical storage tanks
• Basements and sewerage pipelines
• Refractory mixes etc.
• Petroleum Referineries
• Tunnels

G-Chem Microsilica meets the creteria of most of the relevent international and Indian Standard specification. Its packed in 25 kg bags & Big 1 mt Jumbo Bags from Ahmedabad, Gujarat.

Microsilica is a highly reactive pozzolan and gives concrete a denser microstructure, lower permeability higher electrical resistivity leading to improved durability.

Combined with correct design and workmanship, microsilica concrete offers characteristics that will ensure long term durability and service life.

It durability of a reinforced concrete structure can be defined as the capability of the structure to maintain its original functional and structural characteristics during the expected service life in the exposure conditions it was intended for.

 

Microsilica also known as Silica Fume. It's collected and packed from silicon metal or ferrosilicon factories directly, the automatic and integrated production process guarantees the consistent quality. Microsilica are classified as various grades and can be used in Concrete, Oilwell cement, Refractory and Fertilizer industries.

We have marked a remarkable position in the market by offering the best quality array of products to our clients.

Product Information:

European Based Finest filler & additive

G  FINE  Micro FINE ULTRA FINE EROPEAN BASED FINEST FILLER

G  FINE is a new generation supplementary cementitious material (SCM) with a built-in high tech content. In spite of its high fineness it does not increase water demand at the dosage range of 5 to 15 percent of normal OPC in general. In fact concrete slump is seen to be improved, due to the dense packing of cementitious material, producing low void content. The use of G FINE results in hydrated cement matrix to comprise of very small pores.

G  FINE is a specially processed product based on high glass content with high reactivity obtained through the process of controlled granulation. The raw materials are composed primary of low calcium silicates. The processing with other select ingredients results in controlled particle size distribution. G  FINE can also be used as a high range water reducer to improve compressive strength or as a super workability aid to improve flow.

G FINE can be used as practical substitute for Silica Fume as per the results obtained. If the advantages of G  FINE are observed in the concrete mix design, the initial rate of strength development was found to be increased or similar as that of Silica Fume.

 

Where to use G FINE :

Residential, roads, airports, commercial building. Producing mass concrete structures and pile.  In high-rise structures the concrete is to be pump easily.  Low water to binder ration for high performance concrete. Precast concrete element for heavy structures precast units.  To improved initial strength and increase faster .  Better retention of workability and improved strength gain.

Benefits of G  FINE :

The workability of the mix retention is improved Improve durability and permeability of concrete Increased strength of concrete  Reduction in segregation can be observed in the mix  Reduction in heat of hydration of the mix  Non- toxic , eco friendly cost effective, economical solution

G-FINE

Packaging:

G FINE is available in Bulk Jumbo bags with plastic inner liner. The product is also available in 25kg plastic lined bags.

Storage:

G FINE when stored correctly has an indefinite shelf life. Like cement, G-FINE must be protected from contamination and moisture. The product can be stored in bulk in a clean, dry storage silo Or werehouse .

Health and Safety:

Extensive testing has shown G  FINE to be non-toxic and environmentally benign. No known significant health risks are associated with G FINE but high concentrations of dust may cause irritation.
