Welcome
The company Tehnički sistemi d.o.o. from Zagreb has been operating since the end of 1996 and is privately owned. The company’s activity is the direct representation of renowned global companies and the distribution of quality measuring equipment and devices for controlling the physical properties of materials in construction, in the construction and maintenance of roads and road structures, in the paint and varnish industry, and in the decorative industry. The equipment is fully certified and adapted to tests according to HZN, ISO, IEC, CEN, CENELEC as well as some foreign national standards, so we directly represent the following manufacturers: MATEST, PROCEQ, DeFELSKO, INDUSTRIAL PHYSICS, NDT James, ColorLite or smaller companies through occasional distribution.
Activities
The company’s activity is to represent renowned world manufacturers of equipment and devices for measuring and controlling the physical properties of various construction materials when determining:
Mechanical properties
Hardened concrete: strength and resistance to bending and splitting, modulus of elasticity, elongation, bond strength.
Fresh concrete: flow time, spreadability, consistency, porosity, setting and hardening time, workability.
Asphalt: strength and compaction according to the Marshall test, ductility, penetration and rutting tendency, leaching and softening point of bitumen.
Soil: CBR-Proctor test, consolidation and hardening
Steel: wall thickness, tensile strength, surface hardness and toughness – impact resistance, roughness
Surface conditions
Asphalt pavement: night and day visibility coefficient of road markings – retroreflection, flatness, macrotexture, longitudinal and transverse profiles and rutting. Thickness of dry and wet coating layer, adhesion.
Traffic sign foils: night visibility, visibility coefficient.
Other: gloss, chalking, colorimetry, coverage, transparency
Fluid condition
General: viscosity, density, specific gravity, permeability, conductivity
Resistances
General: to UV exposure, to salt fog, to climate effects, to humidity and frost, to heating
Environmental conditions
General: temperature, humidity, dew point
