Circular Cement for Affordable Housing in Kenya

Dr Mwiti Marangu

Congratulations to Dr. Joseph Mwiti from the department of Physical Sciences, Meru University of Science and Technology for winning the Kenya National Innovation Award for the year 2020 in the Built Environment and Housing Technologies Category for the successful development of circular cement that is low cost and eco-friendly. The circular cement is a big milestone towards the realization of affordable housing agenda in Kenya. The cement has been prepared by partial replacement of clinker in cement with local Secondary Cementitious Materials (SCM) as an innovative strategy to lower the cost of cement, promote utilization of wastes and provide greener cement for housing. High abundance and widespread distribution of different types of SCM provides a unique opportunity to produce the circular cement in nearly all counties in Kenya. Mass production is the next stage of this innovation with a view to deliver the product to the market soonest. This will catalyze the achievement of affordable housing agenda in Kenya, offer decent and affordable housing solutions such as slum eradication in developing counties.
