This study successfully applied multi-mode laser cutting with the variation of the laser cutting speed to cement mortar for the first time. The effects of the amount of silica sand in the cement mortar on laser cutting are tested and analyzed. The kerf width and penetration depth of the specimens after laser cutting are investigated. As the laser cutting speed increases, the penetration depth d...

The construction industry is the largest consumer of natural resources which led to depletion of good quality natural sand (Fine aggregates). This situation led us to explore alternative materials and granular slag a waste industrial byproduct is one such material identified for utilization it as replacement of natural sand. This paper highlights upon the feasibility study for the utilization o...

AIMS To evaluate the effectiveness of various antimicrobial mortar formulations in inhibiting the growth of a selection of pathogens of environmental and hygienic concern. METHODS AND RESULTS Mortar prisms containing triclosan-incorporated fibres or different concentrations of silver copper zeolites were incubated with Escherichia coli, Listeria monocytogenes, Salmonella enterica or Staphyloc...

Consider solving a second order elliptic problem when the elliptic coefficient is highly heterogeneous. Generally, a numerical method either uses a very fine computational mesh to resolve the heterogeneities and therefore becomes computationally inefficient, or it performs efficiently on a coarse mesh but gives inaccurate results. Standard nonoverlapping domain decomposition using mortar spaces...

This paper is concerned with the convergence of mortar methods applied to linear elasticity. We prove that the conventional meshdependent norms used in the analysis of mortar methods are bounded below by the BV norm. When combined with standard results, this bound establishes a decomposition-independent and mesh-independent proof of the convergence of mortar methods in linear elasticity. 2005 E...

gypsiferous soils occur in xeric, ustic, and aridic moisture regimes. environmental conditions affect the mode of gypsum formation. gypsiferous soils in fars province, southern iran, are found in piedmont plains, flood plains, and alluvial plains. the objective of this work was to investigate the micromorphology of gypsum crystals formed under different soil moisture regimes. the results indica...

The European LIFE Project, Repolyuse – “REcovery of POLYurethane for reUSE in eco-efficient materials” seeks to solve the environmental challenge resource scarcity and waste management order mitigate effects climate change. material is a prefabricated gypsum mortar form removable roofing plate which residues rigid polyurethane foam have been added. That system reduces weight plates about 30%. i...
