Potential of bamboo leaf ash as supplementary binder materials - A systematic literature review

Abstract

Concrete is one of the most used building materials in contemporary society; however, its production demands large amounts of raw materials and natural resources. Cement production is responsible for the highest CO2 emissions, causing major environmental impacts. The use of industrial waste as a supplementary cementitious material (SCM) has been increasingly studied to reduce and minimize these negative impacts. In this systematic literature review, we investigated the possible use of bamboo leaf ash (BLA) as a SCM. We analyzed 31 papers from four databases and evaluated the effects of calcination conditions of BLA as well as its chemical, physical, mechanical, and durability properties. The literature review demonstrates that BLA presents high pozzolanic reactivity and that composites with cement replacement by BLA present great mechanical properties and increased durability.
