Characterization of composite material from the copolymerized polyphenolic matrix with treated cassava peels starch
Kariuki, Stephen W.; Wachira, Jackson M.; Kawira, Millien; Murithi, Genson L.; Marangu, Joseph M. (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 ... -

Properties of activated blended cement containing high content of calcined clay
Marangu, Joseph M.; Karanja, Thiong’o J.; Wachira, Jackson M. (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 ... -
A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications
Nalobile, Protus; Wachira, Jackson M.; Thiong’o, Joseph K.; Marangu, Joseph M. (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 ...
