Abstract the main objective of this study is to characterize the physicochemical and mineral properties of clay materials from burkina faso to produce stabilized compressed earth blocks cebs. the reactivity of the clay materials was tested based on the electrical conductivity of solutions and the compressive strength of cebs stabilized with 020 wt ccr calcium.
As an example, the frictional properties of steel slag are influenced by its morphology and mineralogy. similarly, the volumetric stability of steel slag is a function of its chemistry and mineralogy. the chemical, mineralogical, and morphological characteristics of steel slag are determined by the processes that generate this material.
Chemical analysis of the data obtained for rca patterns fig. 2a shows a predominance of sio 2 peaks, followed by minor feldspar and caco 3 peaks.although the xrd technique provides a qualitative analysis, the relatively low height of feldspar and caco 3 peaks compared to sio 2 major peaks suggests their low contents. the only mineralogical.

In this paper characterization of recycled materials commercially and laboratory produced, coarse and fine, recycled concrete aggregates rca has been performed. namely, xray fluorescence and xray diffraction xrd analysis were used for chemical and mineralogical analysis respectively.
In this paper, chemicalmineralogical characterization of recycled inert materials was carried out after preliminary crushing and grainsize sorting. xrf and xrd analysis of the dierent grainsize classes allowed us to recognise particular granulometric classes that can be reutilised as rstorder material in the building activity.
In this paper, chemicalmineralogical characterization of recycled inert materials was carried out after preliminary crushing and grainsize sorting. xrf and xrd analysis of the different grainsize classes allowed us to recognise particular granulometric classes that can be reutilised as firstorder material in the building activity.
It was determined that the quality amount of cement of the original concrete that was recycled, has great influence on the granulometry and the chemicalmineralogical composition of the aggregates, since there will be different quantities and qualities of cement paste adhered to the aggregates of according to size.
Multilevel chemical characterization of dutch fine recycled concrete aggregates a comparative study. it was shown that frca from different origins have similar chemical and mineralogical composition and contain comparative chloride content. the chemical composition testing can provide a first line control regarding composition and.
