Nanomaterials are materials with new properties that interact through complex processes at the nanometric scale that include reactions in the quantum field and which still represent an unknown for many researchers. Improving the performance of cement mortar is generally achieved with the help of various additions. Nanoparticles have recently become a material very often used in the additive of various recipes of cementitious materials and not only, because at such a size their properties change surprisingly and th...

The process of selecting and prioritizing investment project proposals in construction is characterized by multiple objectives and uncertainties due to incomplete information and the multitude and dynamics of factors that can intervene. Knowing their significance and influence on the final investment decision, it is a complex problem that requires a multi-critical analysis with both quantitative and qualitative factors, necessary for a good quantification and evaluation. In recent years, the increase in the comple...

The paper contains the results of experimental research on the elaboration of the composition and optimization of the properties of the self-levelling screed based on cement and sand, intended for the fulfilment of the intermediate layer of floors, including industrial enterprises with the aggressive environment; sedentary parts of tanks, basins; bunkers; different containers, etc. The reinforced self-levelling screed has an absolutely horizontal surface. It allows the application of finished layers of composite p...
