ABSTRACTThree clayey materials named MY3, KK and KG originating from the Foumban region (west Cameroon) were analysed to determine their granulometry, plasticity, major-element chemistry and mineralogy. Dilatometric and ceramic behaviour were also investigated. Clays were shaped by uniaxial pressing in a steel mould. Shaped samples were heated at 1300, 1400 and 1500°C. The end products were characterized in terms of their density, porosity and compressive strength. Raw materials differ in terms of their mineralogical composition, grain-size distribution, Al2O3 content and the nature and abundance of impurities inducing specific thermal behaviour during dilatometric analysis and sintering tests. The final material properties may be related to the main features of the raw materials used.

Geopolymer is new binder manufactured from an aluminosilicate source materials synthesized of geopolymer by polycondensation reaction of geopolymeric precursor and alkali polysilicate. Material contains mostly Silicon (Si) and Aluminium (Al) in amorphous form is a possible to be geopolymer source material. Several minerals and industrial by-product materials have been investigated geopolymer materials essentially as a replacement for Ordinary Portland Cement (OPC) and for advanced high-tech composites, ceramic applications, and also as an inorganic polymer coating. This paper reports microstructure properties of various geopolymer properties which are kaolin, white clay and silica sand, from Saudi Arabia by conducting several tests. The characterization and particle morphology of the various geopolymer sources materials was determined using scanning electron microscopy (SEM). X-Ray Fluorescence (XRF) is conducted according to perform elemental analysis and chemical analysis while X-ray Diffraction Analysis (XRD) investigates crystalline material structure, including atomic arrangement, crystalline size, and imperfections.

Compressive strength of cement mortar is an important parameter in the quality control of Portland cement. The limitation of Ottawa sand imports has prompted a study on the potential and utilization of local silica sand available in several regions in Indonesia. The purpose of this study was to investigate the potential and possibility of utilizing local silica sand from several regions in Indonesia including Bangka, Belitung, Sidrap (South Sulawesi Province) as a substitute for standard Ottawa sand in cement mortar testing. Evaluation of local silica sands consisted of SEM analysis, characterization of silica sands and testing of cement mortar compressive strength. Silica sands from Bangka, Belitung and Tuban had silica content of more than 90%, while that from Sidrap was more or less 90%. Based on the SEM analysis, characteristic of silica sands, and compressive strength of cement mortar, local silica sand from Sidrap (South Sulawesi Province) has a good potential to be used as a substitute for standard Ottawa sand in testing of cement mortar.

Two different lime plasters with finely crushed brick are studied in this article. In the first plaster the pozzolan mixture was used as silica sand while in the second it was dosed as replacement of the lime substitute and silica sand (the substitution levels being 20% and 50%). Classic lime plaster was used as a reference material. Studied parameters were basic physical properties (measured by water vacuum saturation and by helium pycnometry), characterization of pore system (by mercury porosimetry) and transport of liquid water.

As the raw materials used in the ceramic materials manufacturing are natural, it is important to use them as a alternative materials, thus decreasing the elements demand taken from nature. This paper aims the characterization of foundry solid powder exhaust from a brazilian company located in Joinville - SC as an alternative raw material for ceramic coating by X-ray diffraction (XRD), thermal analysis (DSC) and thermogravimetric (TG). The dust depletion is caused in the manufacturing mold sand process, when the bentonita (clay), silica sand and coal during the metal parts production are mixed in green sand production. The raw materials were characterized through X-ray diffraction (XRD), thermal (DSC) and thermogravimetric analisys (TG). The atomized powder thermogravimetric analysis curve shows three intervals associated with the mass loss and it is typical of clay commercial application.
