Properties of Concrete and Mortar Containing Locust Bean Pod Ash as Cement Replacement: A Review
Year: 2023
Type: article
Abstract: Global infrastructural development is one of the causes of environmental degradation resulting from the high usage of cement and other nonrenewable materials. These activities have led to a shift in research in the building industry towards the employment of abundant natural raw materials. Locust bean pod (LBP) is a waste product gotten from the harvest of African Locust Bean (Parkia biglobosa). Existing literatures have shown the immense potentials of using locust bean pod ash (LBPA) as a substitute for cement in cement-based products, thus drawing research attention on the subject. This paper presents a conspectus of previous researches on the use of LBPA for concrete and mortar production. Consequently, the effects of LBPA on slump, compressive, flexural, tensile strength as well as some durability properties are discussed. It was concluded that LBPA is pozzolanic and can be satisfactorily utilized as a supplementary cementing material (SCM) to enhance concrete properties with an optimum replacement range of 5 to 15%. The study highlights areas of further research and recommends the adoption of this emerging innovation as a result of its established performance and its potentials for sustainable concrete manufacture.
