Properties of activated blended cement containing high content of calcined clay
(Elsevier, 2018-08)
This paper presents findings of an experimental investigation on sodium sulphate
(Na2SO4) activated calcined clay e Portland cement blends in sulphuric acid media.
Calcined clays were blended with Ordinary Portland Cement ...
Influence of Lysinibacillus sphaericus on compressive strength and water sorptivity in microbial cement mortar
(Elsevier, 2019-11)
Cement structures are subject to degradation either by aggressive media or development of micro/macro cracks
which create external substance ingress pathways. Microbiocementation can be employed as a self-intelligent
solution ...
Characterization of Prototype Formulated Particleboards from Agroindustrial Lignocellulose Biomass Bonded with Chemically Modified Cassava Peel Starch
(Hindawi, 2019)
Conventional methods of making particleboards utilize wood chips. +is has resulted in a decrease in the tree cover due to the
increase in wood demand. +e effect has been climatic change. Wood is bound using phenol ...
Diffusivity of Chloride Ion in Mortar Cubes Made Using Ordinary Portland and Portland Pozzolana Cements
(2014)
Cement is subject to degradation by aggressive media. This study investigated chloride diffusivity in mortar made from Kenyan cements which included three brands of Ordinary Portland Cements (OPC) and three brands of ...
Performance of Potential Pozzolanic Cement in Chloride media
(2014-04)
The paper presents finding of the pozzolanic activity of calcined clays from selected regions of Embu County – Kenya. The results are also presented for the compressive strength development and Chloride ingress resistance ...
Bioremediation of mortar made from Ordinary Portland Cement degraded by Thiobacillus thioparus using Bacillus flexus
(Heliyon, 2021-06)
Cement is widely used as a construction material in the construction industry. However, there are challenges
affecting its durability efficacy. Cement mortar/concrete is subject to degradation by aggressive ions such ...
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 ...
