The Apuan Alps (NW Tuscany) is an important area of Central Italy characterized by large karst systems mainly fed via direct and diffuse water infiltration (autogenic recharge). These waters usually transport a clastic sediment load, originated natural, surface subsurface rock erosion/weathering which, in part, deposited underground. In the Alps, during extreme rain event, huge amounts carbonat...

In this study, the benefits of limestone powder (LP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP and MP are used directly without attempting any additional processing in the production of selfcompacting concrete (SCC). The water to binder ratio is maintained at 0.33 for all mixtures. The examined properties include workability, compressive s...

The method used consists in short-term monitoring programs (microclimate and air quality) carried out in four rooms with different significant aspects. On the basis of climatic data of Rome geographic area, the microclimatic monitoring has been performed during the most critical period (summer to autumn). For chemical control, the total deposited particulate matter was evaluated using a prototy...

Owing to its propensity swell when in contact with water, expansive soil causes severe structural problems and shrinks they dry out. Soil stabilization is a well-known method used enhance the soil's physical engineering properties commonly adopted for improving structures. The mechanical of different soils evaluated by adding varying proportions marble dust (10, 20, 30 percent) Penjwen, Said Sa...
