Nandadeep Undertake the design projects for residential and commercial buildings using arches, vaults, and dome (AVD) using stone or brick as building blocks and lime mortar as the binding material. AVD profiles put every joint of building blocks in compression, and structures with compression last for longer compare to the structures in tension. The use of lime mortar offers very high durability to the structure.

Presently we are doing three residential projects, one at Parbhani and two at Aurangabad. Some of the photo from the residential project are attached below:

Eminently hydraulic lime should be used for the preparation of the lime mortar, the use of fat lime does not allow the development of strength. A lot of research work is carried at Nandadeep for identification , chemical testing, and mechanical parameter testing of the hydraulic lime to make it usable for practical applications.
We recommend the use of semi-dressed stone for the foundation work, instead of using random rubble masonry. The use of semi-dressed stone ensures better earthquake stability for the structure.

Mulling action is very important in lime mortar preparation. This enhances the stickiness property of the lime, and hence roller pan mixer can be used for the preparation of the lime-based mortar.
The brick aggregate gives better bonding with the lime paste when compared with the stone aggregate. We recommend the use of brick aggregates for lime concrete.
