Rocket Fibres

For ages fibres 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 fibres which are readily available and easy to use. Depending on the requirement, one can choose among the various types of fibres available.

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

Cracks are caused mainly because of plastic shrinkage or thermal stress due to fluctuation in ambient temperature. Use of Rocket fibres results in substantial reduction in crack formation. These fibres 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 fibres which form a high strength 3 - dimentional reinforcement network.Water permiability decreases due to the reduction of micro cracks.Rocket fibres 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 fibres 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 fibres are environment friendly and non-hazardous. They disperse and separate easily in the mix. Rocket fibres are safe and easy to use.

Advantages: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 fibres can provide increase in tensile and flexural strength to a designed mix. Unlike steel bars, Rocket fibres disperses in the concrete mass, which results in additional reinforcement. When used in plaster mortar, Rocket fibres provide a 3 - dimentional reinforcement, unlike chicken mesh which proviodes 2 - dimentional reinforcement.

Polypropylene Fibres: Polypropylene fibres are hydrophobic non-corrosive and resistant to alkali, chemicals and chlorides. Due to these above characteristics, polypropylene fibres have no significant effect on water demand of the fresh concrete. Hence these fibres neither intervene the hydration of cement nor do they influence unfavourably 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 fibre 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 fibres ideal for reinforcement.Rocket fibres are polypropylene fibres made from pure and virgin polypropylene, which is suitably treated for proper dispersion. The traingular cross-section of these fibres help in additional reinforcement. The stability of Rocket polypropylene fibres in alkaline condition makes it best suitable for the construction Industry.
