Readers will also be interested in investigations in radio electronics, wind energy and energy management, building materials and geotechnics. The presented scientific articles will be appreciated by many engineers and technologists from the industrial sector, as well as academics and students majoring in engineering science.

We present the 53rd volume of the "International Journal of Engineering Research in Africa" to our readers. This volume contains the articles reflecting the research results in the fields of structural alloys, applied mechanics and mechanical engineering, assessment of the potential efficiency of use the cleaner electricity generation, materials and technologies in construction, biofuel production and chemical treatment of the industrial wastewater, remote sensing, and industrial engineering. The articles will be useful for many engineers as well as for academic teachers and students majoring in the mentioned fields of engineering science.

The 67th issue of the journal includes articles that present the latest research results in chemical engineering for energy production, friction stir welding of polymers, corrosion rate prediction in pipelines, green building materials and structural mechanics, analysis of opening angle on the efficiency of Michell-Banki turbines without guide blades. There are also described neural networks-based modelling to optimise water productivity of passive solar still and model-based approaches for leak detection in water distribution systems, analysis of photovoltaic systems performance in Morrocan regions and a machine learning scheme for speed prediction in intelligent transportation systems. This volume will be helpful to many engineers in machinery, energy production and construction.

In this volume of journal "International Journal of Engineering Research in Africa" are collected articles which describe the results of engineering solutions of actual problems in mechanical engineering, materials processing technologies and chemical technologies, researching and designing of machines, in the designing of control systems for technological processes and engineering management of modern production. Published articles will be useful for professionals from field of mechanical engineering, chemical engineering, engineering management and for students and academic teachers of the related specialties.

High-Volume Mineral Admixtures in Cementitious Binders: Towards Carbon-Neutral Construction delivers an overview of the broad applications of high-volume supplementary cementitious materials (SCMs) in cementitious binders, addressing the most promising ways to use them to reduce carbon emissions in the construction and building industry. This book focuses on the applications and scientific challenges of high-volume SCMs blends, elaborating on the possibilities as well as offering original perspectives on using different kinds of blended cements in the manufacturing process. Emphasis is placed on activity estimation and quality assessment, the properties of high-volume SCM-blends at both the fresh and hardened stages, self-hydraulic properties, and potential use as the sole binder, as well as associated environmental impacts and carbon footprint reduction. - Presents the macro-/microproperties of high-volume (SCMs) cements. - Introduces the state of the art in the use of high-volume SCM cements. - Discusses the associated environmental impacts and the contribution to carbon neutrality by using high-volume SCMs. - Associated with the disposal of man-made waste in the production of building materials. - Discusses the advantages of using waste materials in cement production which reduce environmental impacts and contribute to sustainable development.
