Application of residual ash and sisal fiber in the production of mortar and concrete: Review

Abstract

The industrial development linked to the growing addiction to consumption, obsession with fossil fuels, and general desire for short term profit, cause a certain insensitivity to more sustainable alternatives. The construction industry is a sector in which the incorporation of various types of waste presents as favorable. Three types of waste with different characteristics and origins have proved attractive and advantageous for many developing countries. They are incinerated municipal solid waste, bagasse ash from sugar-cane and sisal fiber. The aim of the paper was to realize a literature review of the characteristics, use and importance of these residues as application in construction. The interest in the re-use of these waste materials as raw material in mortar and concrete allows for proper disposal and minimizing the generation of waste, moreover, would no longer be the primary cause of problems relating to public health and the environment. Fortunately, there is a tendency among researchers to stimulate the search for new raw materials that come from cleaner and renewable sources. All studies referenced in the article showed the feasibility of using sisal fiber and residual ash for the manufacture of concrete and mortar.
