High Strength Concrete Piles - 12 M Length, Low Unit Weight, High Flexural Strength, Corrosion Resistant, High Early Strength

Product Features:
Manufactured in longer length up to 12 m.
Low unit weight, hence lower cost.
High strength concrete of 500 kg/sqcm is used.
Spinning results in denser concrete, reduces water cement ratio and hence increases concrete strength further.
High flexural strength.
Absence of torsional cracking.
High resistance to corrosion especially from sea water.
Consistent quality under factory conditions.
High rate of production ensures early completion of projects.
Eliminate casting yard at site i? a distinct advantage in urban re-development projects.
High early strength enables the pile to be driven 10 days after manufacture.

MANUFACTURING PROCESS The process consists of several activities starting from raw materials to testing and dispatch.
The source of raw materials for concrete, cement, natural stone aggregate and sand are identified and materials tested for suitability. Similarly, H.T. wires conforming to stipulations are procured from renowned manufacturer and test reports verified.
H.T. wires are cut to required size of poles with a margin of about 300 mm and button heading done at ends of pretensioning. Cages are formed with M.S. Wires for helical reinforcement.
The cage is placed in the bottom half of the mould and the calculated quantity of concrete is placed. The top half is than bolted and prestressing of H.T. wires done by a hydraulic jacking system. The mould is then placed on spinning machine and spun at predetermined speeds and duration.
