Sustainable Stone Masonry Blocks
Due to the rapid growth of Indian economy and construction sector, the use of natural resources for manufacturing
of conventional construction materials have increased. It is evident that production of conventional materials leads to large
scale CO2 emissions. Masonry units form the major fraction of any construction activity, and use of masonry units such as
Bricks, Concrete Blocks, Clay Blocks, etc. again lead to enormous pollution.Recent trends have shown huge amount of
Industrial and Natural waste materials being discarded without proper treatment and utilization. Boulders/Stones are present
in abundance quantities near hills and mountains which have no practical importance. Construction demolition wastes are
also good sources of fine and course aggregates which needs refinement and proper segregation to be used as a fresh
construction material. This paper aims at studying the use of natural and industrial waste materials such as Fly-ash, Granite
dust and locally available soil for production of sustainable Stone Masonry Blocks which means little or no damage to
environment and able to continue for future generation. Stones selected from hills and mountains near the site shall be used
in the manufacture of the blocks. The paper also aims at studying the effect of partial and complete replacement of
conventional materials with waste materials in the block. As per BIS a compressive strength of 2MPa is sufficient for a block
to be used as a masonry structure and the present research aims to provide a strength of more than 2Mpa in the block.
