FIELDS OF APPLICATION Concrete screeds for crawl spaces; Inter-floor slabs of buildings; Flat roofs and pitched roofs; Filling of the cavities of the cassavuota masonry. ADVANTAGES High insulation capacity. Extreme simplicity of installation. Lightening of the structure. Stability and homogeneity. Remarkable reliability over time. TECHNICAL FEATURES OF CONCRETE Special lightweight concrete with the use of one-dimensional expanded polystyrene beads. Its use is required to obtain high thermal and acoustic insulation values. The choice of components, their perfect dosage and the treatment of the mixtures in the packaging and casting phase make Isolram a lightweight concrete with high thermo-acoustic resistance. As the density varies, the coefficients of thermal conductivity and mechanical resistance change. Easy to install and easy to apply with the help of fire engines. A minimum thickness of 8 cm is recommended. Density kg / m³: 430 ÷ 700 Compressive strength N / mm²: 0.7 ÷ 1.5 Thermal conductivity kcal / mh ° C 0.10 FIBRORINFORCED concrete Special concrete reinforced with high tenacity synthetic fibers. FIELDS OF APPLICATION Civil and industrial flooring, internal and external; Slabs, slabs, screeds and structures in general with limited thickness; Structures and / or surfaces that present difficulties in suitable curing. ADVANTAGES Reduction of the development of cracks. In fact, the fibers produce the so-called "diffusion effect" inside the mixture, preventing the spread of cracks in the concrete. Redistribution of tensions inside the sheet through a mechanical action, the so-called "reinforcement effect". Greater waterproofness of concrete. Better resistance to impact and fatigue. Durability in chemically aggressive environments (according to the required exposure class). Greater ease and speed of installation. Greater simplicity in the phase of eventual restoration of the pavement with scarification. TECHNICAL CHARACTERISTICS OF CONCRETE Special concrete with guaranteed performance, reinforced with synthetic fibers. The fibers act as an additional aggregate of the concrete. To maintain the workability characteristics, suitable additives are used in the composition of the mixture. The consistency class (S3 S4 S5) is required according to the construction technology of the work (with paver support or manually). Max diameter of the aggregate mm: 8 - 30 Characteristic compressive strength N / mm²: 25 - 45 Consistency S3 S4 S5 Flexural strength N / mm²: 2 - 4 Quantity of fibers kg / m³ 1 - 3 TECHNICAL CHARACTERISTICS OF THE FIBERS Specific weight g / cm³ 0.91 Cut mm 4-6-8-12-18-24 Diameter µ 19.8 (± 3%) (corresponding to 2.8 dtex) Tensile strength Mpa 400 ÷ 500 Elastic modulus Gpa 7 ÷ 9 Durability Excellent resistance to acids, bases and chemicals SELF-COMPACTING concrete Self Compacting Concrete - Self Compacting Concrete. FIELDS OF APPLICATION Self-compacting concrete allows easy realization of complex works, avoiding any compaction and vibration intervention; Ensures perfect face-view, high durability and brilliant mechanical strength; It allows to perform castings with difficulty in laying, such as those characterized by a dense metal reinforcement and / or by the presence of inserts. ADVANTAGES Ease of installation; Superior durability; Continuity and speed of casting; Realization of the most complex structures. TECHNICAL FEATURES OF CONCRETE Concrete with innovative characteristics whose main properties are: high homogeneity: its peculiarities give the structure a homogeneity far superior to that obtainable with other types of concrete; very high fluidity and smoothness that make it flow even in the narrowest interstices of the formworks avoiding any segregation; high durability and impermeability; high viscosity and cohesion; high filling capacity. Max diameter of the aggregate mm: 20 Minimum resistance class N / mm²: 30 Water / cement ratio 0.55 (or less according to the exposure class) Plywood shrinkage concrete Special concrete with compensated shrinkage, prepared with the addition of expansive additive for concrete. FIELDS OF APPLICATION Waterproof castings; Need to contrast the hygrometric shrinkage of the concrete; Construction of tanks, pipes, floors. ADVANTAGES Reduction of the propagation of micro-cracks. Greater waterproofness of concrete. Reduction of the development of cracks. Stability and homogeneity. TECHNICAL CHARACTERISTICS OF CONCRETE Special concrete with compensated shrinkage, prepared with the addition of expansive admixture for concrete. Can only be packaged for reinforced concrete. Max diameter of the aggregate mm: 16 - 30 Compressive strength N / mm²: 30 - 45 Consistenza S2 S3 S4 Quantità percentuale su cemento 5 ÷ 8 powered by netplanet home | chi siamo | unità operative | prodotti | link | contattaci copyright 2015 Ramundo.it partita iva 03537590717
