Our Quality and Performance: The use of straw to reinforce bricks dates back to Egyptian time when horse hair was commonly used to reinforce lime / sand plaster until 1950s, and asbestos, until recently was used for around 100 years as a cement reinforcement for sheets or fiber-proofing products.

Polypropylene is a relatively modern product with a large molecule built up by a repetition of small, simple chemical units until a polymer chain is formed. Polypropylene fibers as a secondary reinforcement, nowadays, are being used extensively throughout the world in all types of constructional concrete. Firstly, they have been proven as an effective method of controlling troublesome shrinkage in concrete. Then, after curing, the presence of fibers increases, the concrete long - term durability and toughness. Our monofilament fibers, which are produced from 100% virgin mono-polymer polypropylene, comply with the requirements of ASTM - C1116 and are developed as a crack - controlling additive for cementations materials. It is available as monofilament 20mm in length for concrete reinforcement and 6mm and 12mm in length for plaster and mortar. PP fibers are true monofilaments that totally disperse into the concrete mixing when added at the batch plant or at the job site.

• Plastering is a process of applying one or more coats of mortar to a concrete surface, brickwork, stone masonry. It must be durable such that it resists the penetration of moisture and should be able to weather uniformly. It should be also pleasing in appearance.
• These properties depend upon materials used, composition of mix, degree of mechanical bond between the plaster and the backing surface and workmanship.
• Lack of bond with the backing more so when chicken mesh is used, cracking, crazing of surface and discoloration are principal defects in plastering
• Roman Coliseum was built with fiber reinforced structure in 80 AD, they used horse-hair as fibers.
• Tipu Sultan’s palace at Srirangpattnam has been built with Sheep's wool
• A Pueblo house built in 1540 with straw reinforcement adobe brick is believed to be the oldest house in USA
• Use of horsehair in plaster
• Have you not seen mud wall in villages with straw reinforcement?
• Fibers provides 3 dimensional secondary reinforcement

Dispersion of Fibers in Mortar

Fibers physical presence and mechanical strength prevents formation of micro cracks throughout the matrix.

• Reduces rebound loss by 50-70%
• Checks dampness, saves on repairing cost
• Improves shatter resistance in walls
• Checks crack propagation while cutting grooves for conduit laying

1 kg of Rocket Fibers contains 14 crores of fibers.

One pouch of 90 gms contains 1.25 to 1.5 crores of fibers.

One sq. ft of plaster contains almost 5 to 15 lakhs of fibers which forms a mesh and gives 3 dimensional secondary reinforcement.

Rocket Polypropylene fibers are very stable in alkaline medium. As our cement is an alkaline medium the Rocket polypropylene fibers are very stable in this medium. They are hydrophobic and get dispersed in water very easily. Hence they get mixed with the mortar homogeneously.

Plaster: Use 6mm/12mm @ 90gms / cement bag in 1:4 cement / sand ratio

Concrete: Use 20mm@ 600gms /cubic meter

Mortar: Use 800gms/cu.mtr.

The above mentioned dosage is just a guideline. It is recommended to optimize the dosage depending the requirement.

• Rebound loss reduced by 50 to 60%
• Less time required for Finishing of Plaster so saving in labour time.
• Protects Chipping of edges and controls cracks.
• No dry cement required for finishing the plaster, hence overall saving of 10% in cement required for overall project plaster. So the cost of fibers is nullified.

Polypropylene fibers are hydrophobic non-corrosive and resistant to alkali, chemicals and chlorides. Due to these above characteristics, polypropylene fibers have no significant effect on water demand of the fresh concrete. Hence these fibers neither intervene the hydration of cement nor do they influence unfavorably on all the constituents of the concrete mixture.

Polypropylene is the lightest synthetic polymer, (sp. gr. is 0.91; when added to water the material floats) hence the count of fiber for a given weight is maximum. For example polyester is 52% heavier in comparison to polypropylene. Similarly nylon and acrylic are 26% heavier than polypropylene. These facts make polypropylene fibers ideal for reinforcement.

Rocket fibers are polypropylene fibers made from pure and virgin polypropylene, which is suitably treated for proper dispersion. The triangular cross-section of these fibers help in additional reinforcement. The stability of Rocket polypropylene fibers in alkaline condition makes it best suitable for the construction Industry.

For ages fibers have been used in construction industry. Houses, made of mud but reinforced by straw, have stood against natural calamities. Historical evidence prove the usage of hair of various animals in the construction of monuments and palaces.

Rocket offers a wide range of high strength synthetic fibers which are readily available and easy to use. Depending on the requirement, one can choose among the various types of fibers available.

Fiber disperses in the cement (concrete / plaster) mix and forms a three dimensional network, when the mixture is caste. This results in additional reinforcement, thereby increasing the quality and durability of the construction.

Concrete possesses high compressible strength but are very brittle and weak in tension. Additional reinforcement results in increase in strength. It is important to note that only fibers can provide increase in tensile and flexural strength to a designed mix. Unlike steel bars, Rocket fibers disperses in the concrete mass, which results in additional reinforcement. When used in plaster mortar, Rocket fibers provide a 3 - dimensional reinforcement, unlike chicken mesh which provides 2 - dimensional reinforcement.

Cracks are caused mainly because of plastic shrinkage or thermal stress due to fluctuation in ambient temperature. Use of Rocket fibers results in substantial reduction in crack formation. These fibers control formation of micro cracks by absorbing the stresses, which is left unchecked, resulting in larger cracks. This is achieved by dispersion of millions of Rocket fibers which form a high strength 3 - dimensional reinforcement network.

Water permeability decreases due to the reduction of micro cracks.

Rocket fibers hold together fine particles of sand, cement and stone chips. This increases the abrasion resistance when exposed to excessive wear from tyres, foot movement, etc.

Rocket fibers reduce rebound loss 'splattering' during plastering, shotcrete and guniting. This results in increased coverage in the first attempt, thereby it reduces the wastage of material and labour time.

Rocket fibers are environment friendly and non-hazardous. They disperse and separate easily in the mix.

Rocket fibers are safe and easy to use.

• 01
• For use in concrete add the fibers directly to the mixer along with water and then add the batch.
• 02
• For plaster, add fibers in a bucket of water and mix vigorously. Spread the water along with fibers over the dry mixture of mortar.
