Strength and Microstructure of a Clayey Soil Stabilized with Natural Stone Industry Waste and Lime or Cement

Industrial waste generated by the natural stone industry when working with limestone and dolostone is mainly composed of calcium carbonate magnesium carbonate. This mineral composition makes soil stabilization a potential use waste. However, much research must be carried out to fully understand aptitude this for improvement. In work, strength microstructure clayey stabilized using powder lime or cement were studied employing following techniques: unconfined compressive tests, mercury intrusion porosimetry, thermogravimetric analysis, X-ray diffraction, scanning electron microscopy. Moreover, effects an aggressive environment simulated sodium sulfate solution. Its investigated from 7 days 6 months. The results obtained show increase in more compact structure samples industrial Therefore, can used as ternary element stabilization.
