Fiberglass rebar area of application
Fittings made of composite materials are a product of new technologies, the technical characteristics of which make it possible to successfully use it as an alternative to traditional steel fittings in construction of:
Foundation;
Marine and port facilities;
Reinforcement of concrete tanks;
Repair and strengthening of bearing capacity of brick and reinforced concrete structures;
Road slabs, airfield slabs;
For the production of small architectural forms;
For the road paving and decking of highway bridges;
The implementation of the infrastructure elements in the chemical industries;
Repair of damaged brick and reinforced concrete structures;
Fittings are used for constructions based on gypsum binders;
Construction of swimming pools and industrial pools;
The application of fiberglass fittings in civil and industrial construction is caused by many variables:
Low specific gravity;
High corrosion resistance;
Low thermal conductivity of composite materials;
High strength, several times the strength of steel fittings;
Is a dielectric;
Durability;
As known, the main drawback of traditional low-carbon steel fittings is a low index of corrosion resistance, which limits their use in the construction of marine facilities and constructions located in the zone of variable water level.
A compact visible spectrometer which allows the direct reading of spectral length and employs a prism for dispersion. It is also useful for flame test of basic radicals (sodium, stronum, potassium, copper etc.) There is a single eyepiece and independent focussing tube for the gracule, which carries an index at 590mm, with Dâ?? marked right below the scale, (corresponding to the wave length of sodium light) can be calibrated to a known light source by adjustment of knurled screw. The amount of light admited to the spectroscope can be regulated by a variable slit, adjusted by a knurled ring round the rating tube.
Floating Bridge is composed of modular air-tight steel boxes suitable for sea and land transportation. It is a kind of bridge floating in water to let vehicles, machines, equipment and personnel get across. It has the advantages of quick delivery, long span length, no pier construction, fast erection and environmental friendliness.
