Abstract

India has a large building materials manufacturing industry. The technologies for manufacture of bricks, lime, lime-pozzolana and roofing materials consist of highly sophisticated as well as age-old traditional processes. The Central Building Research Institute, Roorkee, India developed appropriate semi-mechanized small-scale manufacturing technologies for making bricks, lime, semi-pozzolana (rice-husk ash) and cement-bonded coir-roofing sheet. The institute has all the infrastructure facilities and qualified technical staff to carry out country-wide technology tranfer of the new developed processes. This paper gives a review of the limited success obtained in the attempts of the Institute in technology tranfer. With the last 15 years concentrated efforts it has still not been possible t get the semi-mechanized processes of brick-making and lime manufacture accepted by even 5 percent of these industries in the country, as the investment and technical skill required to adopt the processes are simply beyond the reach of the common people engaged in these industries. As cement is freealy avaliable, and cost of manufacturing lime and pozzolana, in term of actual use, is not attractive, most people do not prefer using these materials. On the other hand rice-husk based pozzolana and coir-fibre sheets have shown doubtful performance in actual use and therefore the transfer of the related technologies were started perhaps at the premature stage. The preference of large government-sponsored construction programmes for use of cement and concrete also contributes to the discouranging situation in tranfer of new building materials technologies
