The cement industry has the potential to become a major consumer of recycled waste materials that are transformed and recycled in various forms as aggregates and pozzolanic materials. These recycled waste materials would otherwise have been dumped in landfill sites, leaving hazardous elements to break down and contaminate the environment. There are several approaches for the reuse of these wast...

Objective: To investigate the physical and strength properties of mortar using locally available mineral admixture. Methodology: The compressive at different temperatures was found. Setting time, consistency, porosity were also studied by blending natural kaolinite metakaolinite (MK) with cement in proportions. An experimental work carried out control mix adding from 5% to 20% ordinary Portland...

This investigation elucidates the mechanical characteristics of geopolymer containing solar panel waste glass. With the SiO2/Na2O molar ratio (S/N = 0.75, 1.0, 1.25, 1.5, 1.75), the percentage of metakaolinite that is replaced by solar panel waste glass (040%), and the curing time of 1, 7, and 28 days as the study variables, the porosity, density, setting time, compressive strength, and flexura...

The aim of this work was to identify parameters that could influence the conversion kaolinite into metakaolinite. To end, dehydroxylation four kaolinites, using controlled rate thermal analysis (CRTA) and thermogravimetric (TGA), investigated. X-ray diffraction (XRD) Fourier transform infra-red (FTIR) were used confirm kaolinitic nature samples. Their crystallinity evaluated Hinckley index from...

Abstract Clays and clay minerals dissolve over a broad pH range, such as during sediment diagenesis in variety of applications, including nuclear waste storage, landfills, geopolymer binders the construction industry. The solubility depends on process parameters (pH, temperature, pressure, etc.) material properties (phase content, mineral composition, particle size, etc.). Pretreatments calcina...

The core-shell method is used as a novel synthetic process of micronized Ti-Zeolite Na-A which involves calcination at 700°C of coated Egyptian Kaolin with titanium tetrachloride in acidic medium as the first step. The produced Ti-coated metakaolinite is subjected to microwave irradiation at low temperature of 80°C for 2 h. The prepared micronized Ti-containing Zeolites-A (Ti-Z-A) is characteri...
