CONSTRUCTION & URBAN PLANNING GLOSSARY
Standardized architectural, structural, and regulatory definitions. Clarifies essential abbreviations (POT, CUT, RH, AC), building physics metrics (U-value, thermal bridges), and Romanian construction law frameworks (Legea 50/1991, Legea 10/1995).
Concrete Curing (Tratarea / Maturarea Betonului)(Maturarea și Tratarea Betonului Proaspăt)
RO: Tratarea Betonului
The controlled process of maintaining moisture and favorable temperature in freshly poured concrete for a specified duration (typically minimum 7 days per NE 012-1:2022) to allow complete cement hydration and prevent plastic shrinkage cracking.
Achieved via water sprinkling, wet burlap covering, or spraying chemical curing curing membranes (pelicule de protecție).
Reinforcement (Armătură)(Armătură din Oțel Beton)
RO: Armătură
Steel bars, mesh, or fibers embedded in concrete to provide tensile and shear strength.
Assembled according to structural engineering rebar bending schedules (extrase de armătură).
Aggregate (Agregate Minerale)(Nisip, Pietriș și Criblură)
RO: Agregate
Granular mineral materials (sand, gravel, crushed rock) constituting 70-80% of concrete volume.
Graded per standard sieve curves (0-4mm, 4-8mm, 8-16mm, 16-31.5mm) per SR EN 12620.
Hydraulic Cement (Ciment)(Ciment Portland și Ciment Compozit)
RO: Ciment
A finely ground inorganic hydraulic binder that sets and hardens by reacting with water (hydration) to form insoluble crystalline calcium silicate hydrates.
Classified into CEM I - CEM V per SR EN 197-1.
Mortar (Mortar de Zidărie și Tencuială)(Mortar Industrial Uscat)
RO: Mortar
A workable mixture of cementitious binders, fine aggregates (sand <2mm), water, and admixtures used to bind masonry units or coat wall surfaces.
Classified by compressive strength (e.g., M5, M10 per SR EN 998-2).
Screed (Șapă de Pardoseală)(Șapă pe Bază de Ciment / Anhidrit)
RO: Șapă
A layer of cementitious mortar laid in-situ to obtain a smooth, level floor surface suitable for receiving final floor finishes or encapsulating underfloor heating pipes.
Classified into CT-C20-F4 (Cementitious, 20 MPa compressive, 4 MPa flexural).
