Estimating the amount of material without significant losses at end hybrid casting is a problem addressed in this study. To minimize manufacturing costs and improve accuracy results, correction factor (CF) was used formula to estimate volume percent order reduce during sample stage, allowing for greater confidence between approved blending plan results obtained. In context, three mixing schemes different sizes shapes (gypsum plaster, sand (0/2), gravel (2/4), Posidonia oceanica fibers (PO))...
This study explores the hydrogeological conditions of a landslide-prone hillslope in Upper Mosel valley, Luxembourg. The investigation program included monitoring piezometer wells, field tests, analysis drillcore records, and geophysical surveys. Monitoring testing some observation wells indicated very pronounced preferential flow. Electrical resistivity tomography (ERT) self-potential methods were employed area for exploration morphology flowpaths. Possible signals associated with flowing...
This study presents the comparison of experimental results with assumptions used in numerical models. The aim field experiments is to test linear relationship between different hydraulic parameters and soil detachment. For example correlations shear stress, unit length force, stream power, power effective detachment rate does not reveal a single parameter which consistently displays best correlation. More importantly, fit only vary from one experiment another, but even distinct measurement...
A systematic study was undertaken of the granular composition and hydraulic properties municipal solid waste (MSW) produced by mechanical–biological pretreatment (MBP–MSW) from three different treatment plants with aim evaluating potential application MBP–MSW as an alternative barrier material for landfill final cover systems. Despite its coarse composition, has low conductivity. Long-term permeability tests show that conductivity decreases time. The most likely explanation long-term changes...
Gypsum (GPS) has great potential for structural fire protection and is increasingly used in construction due to its high-water retention purity. However, many researchers aim improve physical mechanical properties by adding other organic or inorganic materials such as fibers, recycled GPS, waste residues. This study a novel method add non-natural GPS from factory (phosphogypsum (PG)) secondary material GPS. paper proposes mix these two properly the effect of PG on physico-mechanical...
High CO2 emissions and rising energy costs result in an increasing demand for innovative, environmentally friendly energy-efficient construction materials. Gravel wash mud (GWM) is a widely available industrial by-product from gravel mining which may be used as aluminosilicate source the production of cementitious In this study, GWM Eifel SW Germany was synthesis alkali-activated cement. A high NaOH leachable Si Al content fine grain-size makes material particularly applicable cements...
Roof and wall slates are fine-grained rocks with slaty cleavage, it is often difficult to determine their mineral composition. A new norm calculation called slatecalculation allows the determination of a virtual composition based on full chemical analysis, including amounts carbon dioxide (CO2), (C), sulfur (S). Derived minerals include feldspars, carbonates, micas, hydro-micas, chlorites, ore-minerals, quartz. The components slate assessed superior accuracy compared petrographic analysis...
Abstract. In spring 2009, four rill experiments were accomplished on a fallow land. Most external factors as well discharge quantity (9 L min-1) held constant or at least in the same range. Following most process based soil erosion models, detachment runoff values should therefore be similar, but experimental results show clear differences sediment concentration, and other measured calculated values. This fact underlines problems of models: concerning erosion, different processes take part...
