Prediction of Compressive Strength of Calcined Clay Based Cement Mortars Using Support Vector Machine and Artificial Neural Network Techniques
(Research Gate, 2020)
Prediction of strength in cement based materials is vital in construction industry as it forms the basis upon which important
tasks can be performed such as the time for mortar form removal, project scheduling and quality ...
Effects of Sulfuric Acid Attack on Hydrated Calcined Clay Limestone Cement Mortars
(Taylor & Francis, 2020)
The paper presents experimental findings on the performance of Limestone Calcined Clay Cement (LC3) in acidic media. LC3 was made by inter-grinding a blend of 50 % clinker with ground 30 % Fired Rejected Clay Bricks (FRCB), ...
Characterization of Composite Material from the Copolymerized Polyphenolic Matrix with treated Cassava Peels Starch
(Elsevier, 2020)
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 not ...
Effects of Biocementation on some Properties of Cement-Based Materials Incorporating Bacillus Species Bacteria
(Taylor & Francis, 2019)
There is a growing need in the construction industry to improve transfer and durability aspects of Portland pozzolana cement. Ureolytic bacteria have recently emerged as potential micro-organisms well known for precipitation ...
Pyroprocessing and the Optimum Mix Ratio of Rice Husks, Broken Bricks and Spent Bleaching Earth to Make Pozzolanic Cement
(Elsevier, 2019)
This paper presents the findings of an experimental investigation on optimizing pozzolanic activity of a blend of Rice Husks (RH), Spent Bleaching Earth (SBE) and Broken Bricks (BB) to form pozzolana that would have ...
Study on the Effect of Thiobacillus Intermedius Bacteria on the Physico-Mechanical Properties of Mortars of Ordinary Portland Cement
(PubMed, 2020)
Most of concrete structural failures are attributed to poor workmanship and poor engineering designs. Some microorganisms present in sewer systems can degrade the concrete and/or mortar. Concrete failures due to microbial ...
A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications
(Elsevier, 2020)
Pyroprocessing is an important stage in cement manufacturing. In this process, materials are subjected to high temperatures so asto cause a chemical or physical change. Its control improves efficiency in energy utilization ...
Physico-Chemical Properties of Kenyan made Calcined Clay-Limestone Cement (LC3).
(Elsevier, 2020)
In Kenya fired clay bricks are mainly used as construction materials. However, vast quantities of these Fired Rejected Clay Bricks (FRCB) generated are rejected annually as a result of improper calcination or demolition ...
Physicochemical Performance of Portland-Rice Husk Ash-Calcined Clay-Dried Acetylene Lime Sludge Cement in Sulphate and Chloride Media
(ResearchGate GmbH, 2019)
This paper reports leach and/or intake of SO42−, Cl−, Ca2+, Na+, and K+ from and/or into cement mortar cubes made from a novel cementious material in naturally encountered environmental simulated media. The paper also ...
Chloride Ingress in Chemically Activated Calcined Clay-Based Cement
(Elsevier, 2018)
Chloride-laden environments pose serious durability concerns in cement based materials. This paper presents the findings of chloride ingress in chemically activated calcined Clay-Ordinary Portland Cement blended mortars. ...
