The buildings were originally constructed with concrete mix (1 cement: 1.5 sand: 3 coarse aggregates) with a minimum strength requirement of 20 N/mm2 min., so it was decided that the polymer modified repair mortar must have a compressive strength of 25 N/mm2. Based on the polymer test reports, the concrete mix are used in the construction of these buildings, and the extent of damage. We, Gubbi Civil Engineers are the leading Polymer Modified Mortar Contractor in the Indian industry. Trust our expertise with the professionals leading the industry since 30 years.
There are many cases where the steel corrodes due to various causes such as lack of cover, leakage of roofs & walls etc. One of the most common treatments for such structural strengthening is polymer mortar treatment. In this we remove all loose particles of mortar, concrete, rust, etc. from the spoiled surface and apply polymer modified mortar over the necessary surface as per the manufacturer’s specification.
The technique of Column Jacketing improves and restores the capacity of the reinforced concrete column. Column jacketing for RCC columns helps to increase the load-bearing capacity. Column jacketing improves the axial and shear strength of columns. Concrete jacketing or micro concrete jacketing technique increases the existing strength of structural components like a beam, columns. Concrete jacketing shields the concrete against deterioration and nourishes its strength capacity. The technique of steel jacketing with variable vertical angles upgrades the load-carrying capacity of the rectangular reinforced concrete column under eccentric loads.
Advantages of the column jacketing include high early and ultimate strength, durability, appearance, protection of steel, increase in the column’s shear capacity, prevention of shrinkage in the plastic stage due to gaseous properties, and increased flexural strength.
The jacketing of beams gives the ultimate strength and stiffness to the structure by providing continuity to the columns. The jacketing of beams is one of the beneficial methods for strengthening and repairing RC beams. Beam jacketing safeguards the structural beams against design errors, concrete production deficiency, earthquakes or environmental factors, or changes in the functionality of the structure etc.
Beam jacketing of RC beams adds a new layer of concrete to the existing cross-section reinforced with longitudinal and transverse reinforcement.
Fibre Reinforced Polymer or FRP Jacketing is popularly used for the process of strengthening. FRP jacketing is known to be very effective for confinement and shear strengthening. FRP jacketing are proven ductile for structure against seismic activities.
