Properties of eco-friendly cement mortar designed with grounded lead glass used as supplementary cementitious material.

The purpose of this research is to highlight the effect of adding Leaded Glass Powder (LGP) to cement matrices. To achieve this, glass from Cathode-Ray Tube (CRT) with reactive elements (SiO + AlO + FeO) of 26.66% (determined by XRF) is collected and grounded to a particle size of 75 μm, before adding to a CPJ CEM II/A-P 42.

Statistical analysis of Nkoulou soils properties and suitability for earthen constructions.

The present work consists of sampling, characterizing, classifying, and studying the soils of the locality of Nkoulou for the manufacture of cement-stabilized compressed earth bricks (CEBs) and possible use in road building. 08 samples were taken on 02 sites. Chemical and mineralogical characterization identified these soils as ferric-dominated laterites consisting of quartz, illite, hematite, kaolinite, goethite, gibbsite, muscovite, and magnesite associated with trace minerals.
