    A Review on Pyroprocessing Techniques for Selected Wastes Used for Blended Cement Production Applications 

    Nalobile, Protus; Muthengia, Wachira J.; Thiong’o, Joseph Karanja; Marangu, Joseph Mwiti (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). 

    Marangu, Joseph Mwiti (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 ...
