Abstract

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. Graphical abstract: Image 1 Highlights: Pozzolanic activity of bamboo leaf ash in cementitious materials is reviewed. Calcination conditions and particle size influence in mechanical strength. Use of BLA increase the mechanical properties in later age of curing. BLA in concrete helps to reduce the cost and environmental impacts. This paper aims to encourage and promote the use of BLA in cementitious materials.
