Constrobond Pre Mix Brick Mortar

Product Introduction

ConstroBond Pre Mix Brick Mortar is a semi premix high quality mortar for jointing and bonding of Fly-Ash Blocks (Aerated Autoclaved), concrete blocks, hollow blocks, clay bricks and fly ash bricks. ConstroBond Pre Mix Brick Mortar premix consists of cement, graded sand and specialised polymers which combine to give superior strength, water retention and stability. It replaces the conventional method and material of jointing mortar which requires a 12-18 mm thickness With revolutionary 2-3 mm joint thickness. ConstroBond Pre Mix Brick Mortar only requires addition of water before application to prepare the product for use, reducing the hassle of measuring and maintaining various individual elements to create a conventional mortar.

Note :

All results are rounded off to 2 decimal places.
The quantity ascertained is without the consideration of wastage and coping.
Thickness of Mortar considered is approx. 2.5 mm in the above calculation.
Calculations of only standard sizes are given, for the rest of the sizes kindly view our website or contact our company executive.
The result of 170 square feet per 40 Kg of Mortar was derived after a demo wall built at our Laboratory.

Features	Advantages	Benefits
Thin joints	Reduces overall jointing material requirement Reduces storage requirement Reduced seepage in comparison to conventional method	Cost is reduced Results in savings on site storage space and handling Protects valuable points on walls
Semi-premix	Only water needs to be added before application Easy application	No need to procure different materials No need to maintain ratio of entire mix
Self-curing properties	Water curing is not required after application	Saves water Saves time Save labour cost
Slow initial setting mortar	More time for block levelling Low Initial heat of hydration	Better workmanship is possible
Strength designed to suit Fly Ash Blocks (Aerated Autoclaved)	Provides higher Compressive and Tensile Adhesion strength	Better wall strength and long term durability is possible
Higher coverage in comparison to conventional mortar	Reduces overall material requirement Increased work output	Cost and time savings
Technical assistance	Our technical representatives provide you with services like sampling of products, doing site audits and are available for technical assistance	Higher construction efficiency
Consists of materials that are non-hazardous	Health safety for masons	Resulting in hygiene and healthy
No raking required	Raking of the joints or “U" grooving of the joints are not required before plastering	Saves time and manpower
