A. Mortarex Mix is a perfect blend of high-performance Cement with washed plaster sand. It provides rapid strength gain, high durability and low shrinkage. It is used for horizontal, vertical and overhead plaster and concrete projects. It must be mixed with water and it will reach the structural strength in one hour.

A. No, the high-performance properties come from the Cement in the mix.

A. Bonding Agents are not required. Proper surface preparation is the main component in achieving a good bond. If Bonding Agents are desired, they should be used as a supplement to good surface preparation, but not as a substitute.

A. Blending with other products may give unpredictable results, and is not recommended. The use of its approved additives and various colours are acceptable.

A. Only 3-4mm thick layer is good enough for the purpose that provides high bonding strength.

A. You should add around 11-14 ltrs. of potable water with a Mortarex TM bag. The use of a mechanical mixer or drill-mounted mixer is recommended. To maximize working time, you should organize work so that all people and equipments are in their desired place before mixing.

A. You can deploy traditional methods to place and strike-off to desired level. Mortarex TM is fast and does not leak water. Thus, you should apply your final finish immediately after placing. You should organize your tools and people for initiating the work quickly. On Flat work, you should fill to full depth and proceed horizontally. DO NOT place in layers.

A. The objective of water curing is to maintain a wet surface until the product has achieved sufficient strength. You should begin curing as soon as the surface loses its moist sheen, and continue this for a minimum of 1 hour.

A. You should roughen the surface and remove the damaged or contaminated concrete. Ensure that the repair surface is not contaminated by oil, paint, acids, dirt or other materials that will prevent a good bond. You should saturate the repair surface with water immediately prior to placement, and then remove any standing water.

A. One bag of Mortarex TM yields approximately 1.7 cubic meters.

A. Mortarex TM has a Shelf Life of 6 months when stored in a dry location.

These products are certified under the green rating system due to its sustainable material envelope. They provide the advantage of credit points to the developers.

A.Yes, these AAC Blocks are eco-friendly construction material. They help in conserving and protecting earth’s natural resources, unlike bricks, which consume the top layer of the soil. These are manufactured from Fly ash, which is an industrial waste produced by thermal power plant.

A. Ecorex AAC Blocks are manufactured at the state-of-the-art manufacturing facility deploying semi-automatic German technology. This facility is fully equipped with latest technological innovations, including horizontal curing and green separation. This ensures that our clients receive superior quality products. In addition to these, we also provide our clients with a distinctive feature of Tongue and Groove along with Hand Grips for facilitating fast work, precise alignment and savings on joining mortar.

A. AAC Blocks have been in use for over 90 years across the globe. Structures that have been built almost 80 years ago are still intact. However, it is still an evolving product in India.

A. AAC Block was first developed in 1924 in Sweden by an Architectural Science lecturer. He was looking to develop an alternative building material exhibiting properties similar to that of wood, including good thermal insulation, strong structure, convenient to use and fire & termite resistant.

A. Durability of Ecorex AAC Blocks has been proven across all climatic conditions right from Northern Ireland to the dusty deserts of the Middle East. AAC Blocks demonstrate resistance to fire, termites, moisture and earthquake. They have a longer shelf life as they don’t decay like woods and bricks. At the same time, the millions of tiny cells in AAC Blocks provide protection from moisture and increases the survival possibilities during an earthquake.

A. The K value of Ecorex AAC Blocks is around 0.16W/Mk. This provides a strong thermal insulation of walls with an energy saving of up to 20%.

A. Yes, Ecorex AAC Blocks are lightweight. Thus, they help absorb the impact of an earthquake on a fixed structure and improve the chances of survival.

A. Hand Grips facilitate easy handling and placing of AAC Blocks. This helps reduce the wastage and aids in quicker completion of work. Tongue and Groove provide an automatic alignment of the wall. This helps eliminate the need to check plumb. In addition to saving time and money, these also help reduce mortar consumption and provide accurate wall.

A. AAC Blocks are highly recommended for high rise buildings due to its light weight. These also help reduce the total dead load of the structure, which directly boosts the structural savings up to 20%.

A. The strength of Ecorex AAC Blocks is as per IS: 2185:1984 (Part III). This makes them safe and strong to be used for any non-loading bearing walling applications.
