Description

POLYMER MORTAR is a general purpose non-shrink, cementitious, trowel applied single pack repair mortar for repairs to Concrete sections and Plastered surfaces.

POLYMER MORTAR is composed of good quality cement, properly selected aggregates & additives. It is used & designed for repairing of damaged reinforced concrete elements like columns, beams & structure

Areas of Application
Any General Concrete Repairs areas such as –

• Ceiling surfaces, Wall plaster, facade, etc.
• Concrete substrates
• Patch and Repair Mortars: Grouts for repairing cracks and de-lamination of concrete structures such as sidewalks, driveways, and walls. New mortar will not stick well to old concrete without polymer modification.

Features & Benefits

• Ready to use Cement based Polymer mortar – No need to add sand, cement & aggregates, so saves time & energy
• Needs to be mixed with water only – No additional dispersion liquid is necessary
• High bonding strength –Suitable for overhead surfaces & can also be sprayed
• Multi-purpose – Can be applied on horizontal, vertical and overhead surfaces without any form work and can be used along with plastic or steel fibers
• Low permeability – Offers extremely low permeability to water carbon dioxide and chlorides
• Improved workability. Polymer modification noticeably improves application characteristics, making the mortar more fluid and easier to handle and apply.
• Improved strength and durability. Cured polymer-modified mortars generally have improved tensile strength, flexural strength, impact and abrasion resistance, water resistance, and chemical resistance versus unmodified mortars

Typical Properties

• Nature: Cementitious grey powder
• Chloride Content: Nil
• Depth of Carbonation: Nil
• Wet Density: 2250 kg/m3 giving a yield of 13l/25 kgs bag at flowable consistency(W/P = 0.16)
• Flexural Strength: @28 days 25℃ 10 N/mm2
• Compressive Strength: @28 days 25℃ 55 N/mm2
