The Impact

Concrete-Filled Steel Tube with high capacity, good ductility and toughness, convenient construction, good fire resistance and other advantages. Currently[1] . Concrete-Filled Steel Tube structure has been widely used in the basic components and the overall structure of behavioral research has made many achievements. There are many advantages of concrete pipe above, but it also has fatal flaws, Stainless steel steel that is the difference[2]. The stainless steel has a beautiful appearance, durability, corrosion resistance, low maintenance costs, good fire resistance and other advantages. New stainless steel pipe concrete structure has both ordinary steel concrete good mechanical properties and excellent durability of stainless steel, can be widely used in buildings and bridges of the marine environment as well as some of the high durability and aesthetic requirements important building structures. Based on the outer stainless steel hollow sandwich - the carbon steel pipe shaft of light pressure test concrete results of load and displacement of the structure, variation of load and strain, and the impact of the empty heart of these parameters.

Resistance Performance

Recycled concrete was waste concrete re-processing to restore the original performance, so that the waste of resources to re-use. It’s important to study the recycled concrete fire resistance, by analyzing the frequency of the existing building fire, the extent of waste concrete increasing year by year. Through the analysis of recycled concrete as structural components in the deficiencies of strength, seismic and fire resistance, indicates the importance of anti - fire properties of recycled concrete - filled steel tube.

Concrete Core

Currently, in Ukraine and abroad for the construction of high-rise buildings and structures using pipe-like structures. Wide application of pipe concrete columns is due to their high carrying capacity at relatively smaller overall dimensions due to the blocking of cracking in concrete by a steel clasp. The advantages of concrete columns should include more simplified conditions of technology of manufacturing and installation on their basis of bearing structures of floor covering. Piping constructions consist of steel shells and concrete core. Since the steel pipe mainly provides the bearing capacity of the concrete column, its failure or reduction of stiffness, which is characteristic of the fire under the influence of its thermal factors, leads to destruction. Investigation of fire resistance of concrete structures, which are not protected by flame retardant coatings, showed that a steel clasp during a fire after 15 minutes is heated to a critical temperature of 500 ° C.The use of flame retardant coatings is an effective method of fire protection of concrete constructions, which prevents the rapid heating of steel welds and provides a normalized fire resistance limit for such structures. In this work, studies were carried out on the effectiveness of fire protection of concrete columns with different types of fire-retardant materials - mineral wool slabs, special flame retardants and flame-retardant coatings. For fire protection mineral wool materials were used ROCKWOOL plates of the series "Conlit SL150". Mineral wool plates "Conlit SL 150" consist of fibers of rocks of a basalt group, they can withstand, without melting, temperature more than 1000 ° С. The silica-based adhesive "Conlit Glue" can withstand temperatures above 900 ° C, has good adhesion when bonding Conlit SL 150 mineral wool slabs with protective structures. From the second type of fire-retardant materials, the fire-proof composition "Naktresk" was chosen on the basis of gypsum. The coating is formed in the process due to hardening of the mixture on protected surfaces. The third type of flame retardant materials is the flame-retardant intumessent coating "Pyro-Safe Flammoplast SP-A2".It has been established that with the use of fire protection systems on the basis of mineral wool plates "Conlit SL150" and fire retardant "Nutresc", the fire resistance class of reinforced concrete columns increases from R 15 to R 180. The fire protection system on the basis of the painted paint "Pyro-Safe Flammoplast SP-A2" »Increases fire resistance from R 15 to R 75
