| Title: | Developments in Cement-Bonded Composite Material Technology |
| Authors: | Karade, S R |

| Abstract: | Plain cement mortar and concrete are brittle materials having a very low tensile strength. Besides this
they have high density and thermal conductivity. To overcome these problems synthetic fibres and
lightweight aggregates or various lignocellulosic materials like wood, natural fibres and agro wastes
are incorporated in cementitious matrix. The resultant composites are lightweight and have greater
toughness. They have diverse applications in building construction. Cement bonded composites have
emerged as an important building material during the later large part of the last century. Efforts have
been made to use lignocellulosic wastes, which are generated in huge quantity throughout the world
and causing various environmental problems. Use of these wastes in making construction materials
could reduce the magnitude of the problem. However, in this effort there are various restraints like
compatibility of these wastes with cement, their toxicity, and limited composite strength. Moreover,
uniform quality of these wastes is not available to the industry throughout the year. This paper reviews
the results of recent research into the use of these wastes and other wastes like fly ash and blast furnace
slag in making cement-bonded composite materials. Various approaches adopted to overcome
aforementioned problems are described. The benefits and limitations of the use of such materials in
building construction are also discussed. |
