The applications of sisal fibre-based materials in the built environment: opportunities for South Africa

Author: Dlungwana, Wilkin S ; Mapiravana, Joseph ; Ampofo-Anti, Naa Lamkai ; Dumani, Nozonke Date: Dec 2017 The building sector represented the largest uptake globally of natural fibre reinforced composites (NFRCs)1 in 2005 (Sharma et al, 2007). As the sector which consumes about 50% of all raw materials extracted from the Earth’s crust annually ... Read more
Building materials for a sustainable future – cement

Author: Mapiravana, Joseph Date: Mar 2014 Concrete is second only to water in terms of the most consumed substances on earth. Cement is the "glue" which holds concrete together and it is therefore a construction material which is produced and consumed in huge quantities worldwide. ... Read more
Comparative studies of Alkali activated South African Class F and Mongolian Class C fly ashes

Author: Temuujin, J ; Mapiravana, Joseph ; Bayarzul, U ; Oyun-Erdene, G ; Zolzaya, TS ; Darkhijav, B ; Dlamini, Mandla N ; Rüscher, CH Date: Mar 2017 The 7 days compressive strength of alkali activation of class C fly ash from Mongolia (Banganuur fly ash) and class F fly ashes from South Africa (Ash Resources, Ulala) were measured, depending on different waterglass (WG) to sodium hydroxide ...

Cradle-to-gate environmental life cycle assessment of limestone calcined clay cement (LC3)

Author: Dumani, Nozonke ; Mapiravana, Joseph Date: Jan 2024 The manufacturing of cement contributes to approximately 5-7% of global anthropogenic carbon dioxide emissions, necessitating the need for reducing the environmental impact. Limestone Calcined Clay Cement (LC3) has emerged as a promising ... Read more
Labour-based construction, testing and monitoring of proof-of-concept ultrathin continuously reinforced concrete pavement technology demonstrators

Author: Dlamini, N ; Mapiravana, Joseph Date: Sep 2011 For this workshop, members of the Regional research alliance (RRA) and delegates from the construction industry were invited to present ideas and contribute towards the implementation of Ultrathin Concrete road pavements. Dr. Joe Mapiravana ... Read more
Sisal fibre pull-out behaviour as a guide to matrix selection for the production of sisal fibre reinforced cement matrix composites

Author: Mapiravana, Joseph ; Dlamini, Mandla Date: Dec 2011 Natural fibre reinforced cement composites are promising potential materials for use in panelised construction. The structural properties of these composite materials are yet to be fully understood. As the role of the natural fibre is to ... Read more
Sustainable materials in building and architecture

Author: Van Wyk, Llewellyn V ; Mapiravana, Joseph ; Ampofo-Anti, N Date: Jan 2012 Most buildings up to the early nineteenth century, with the notable exception of prestigious public buildings, were constructed from easily available local materials. In the nineteenth century, developments in transport modes enabled the ... Read more
Trends in building materials

Author: Mapiravana, Joseph Date: Jul 2012 This paper was motivated by the need to identify trends in building materials research development and application that will significantly reduce building costs, life cycle costs and minimise the lead time for building delivery in South Africa ...
