Relationship between strength and mixture of rice hull ash (RHA) - cement hollow blocks

Abstract

Our Country today is facing with the problem of rapidly rising demand for new houses. Yet the building of low-cost housing project is hampered by a lack of such building materials. In this regard, government should actively pursue policies that lend priority to housing. Joint research and development programs should be initiated to solve the problem of providing adequate shelter for millions of people. There are significant advances in scientific and technological research that have been registered particularly in some countries, with respect to low cost construction techniques and building materials. The cost of transferring technologies to the developing countries, however, is often prohibitive, thus rendering these country with the appropriate technologies almost impossible. The net result is the pronounced technology gap between the developed and under develop countries.

This manual is designed to increase the awareness of modern technologies related to construction. The information presented here has been collated from all available sources and literature of the subject and put together for the convenience of the readers, to wit; specifiers or end users, and the manufacturers or producers. It is hoped that this work can provide relevant state-of-the-art report on the rice-husk ash cement production technology.
