Influence of Starkeya novella on Mechanical and Microstructural Properties of Cement Mortars
(Hindawi, 2020-04)
Cement-based materials are subject to degradation during their service life. Most of the structural failures have been associated with corrosion of the rebar due to chloride ingress, alkali aggregate reaction, and/or sulfate ...
Biocementation Influence on Flexural Strength and Chloride Ingress by Lysinibacillus sphaericus and Bacillus megaterium in Mortar Structures
(Hindawi, 2020-05)
The concrete/mortar durability performance depends mainly on the environmental conditions, the microstructures, and its chemistry. Cement structures are subject to deterioration by the ingress of aggressive media. This ...
A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications
(Hindawi, 2020-08)
Pyroprocessing is an important stage in cement manufacturing. In this process, materials are subjected to high temperatures so as
to cause a chemical or physical change. Its control improves efficiency in energy utilization ...
Characterization of composite material from the copolymerized polyphenolic matrix with treated cassava peels starch
(Heliyon, 2020-07)
Conventional binders in the particleboards formulation involve use of formaldehyde resins. Epidemiologic studies
show that formaldehyde is carcinogenic. Efforts to reduce formaldehyde emissions by use of scavengers has ...
Crop residues used as lignocellulose materials for particleboards formulation
(Heliyon, 2020-09)
Efforts to reduce pressure on use of wood in particleboard formulation have included the use of non-wood materials such as crop residues. Physical and mechanical properties are determined by the number of the hydroxyl
(-OH) ...
Effect of Bacillus cohnii on Some Physicomechanical and Microstructural Properties of Ordinary Portland Cement
(Hindawi, 2020-09)
Cement-made materials face durability and sustainability challenges. (is is majorly caused by the presence of cracks. Cracking
affects the mechanical strength of cement-based materials. Microbiologically induced calcite ...
