Adhesion refers to the ability of concrete to resist slipping of reinforcement under loading in reinforced concrete products. The term "reinforced concrete" is considered as a uniform composite material as long as there is adhesion on the contact surface between the reinforcement and the concrete. In case of disruption of the reinforcement and concrete interaction, the construction is represented by separate elements. The aim of this work is to simulate the process of glass composite and metal reinforcement adhesion with cement concrete. To solve this problem, analytical modeling was performed in the ANSYS 19.0 Workbench software package, with the help of which the nature of damage accumulation in the rebar and the distribution of stresses in the concrete mass are determined.

Nowadays, construction often is used a composite material. Including fibro concrete of reinforcing synthetic fibers. In this title was survey the effect of fiber reinforcement. PAN and HC on the properties of concrete in depend of length fibers, its design, types dressing, composition of concrete, aggregate fineness and etc. As a result of influence was revealed that is not depend of length fibers in the same mobility of concrete mix and differente flow consumption of cement concrete strength in compressive decreases and increases a concrete of fiber. The same conditions strength concrete in flexural with increases content fibro rising. In attendance fibro model is deformation decreases but maximum permission increase.

The paper is dedicated to the analysis interactions between the structure of a field-based cylindrical tank made from reinforced concrete and randomly or unevenly distributed strata of subsoil. The numerical analysis with the use of the Z_Soil software package was carried out to investigate how variable geotechnical parameters demonstrated by subsoil strata with a low bearing capacity and a high deformability influence strain and stress of the tank shell and bottom. The arrangement made up of a cylindrical tank and stratified subsoil (its 3D model) was subjected to the analysis with the consideration of the elastic and plastic properties of soil (the Coulomb-Mohr model). The analysis results, presented as diagrams of the structure deformation and stresses illustrate the uneven settlement of the tank shell and its internal strain.

Different Types

Concrete is weak in tension, hence some measures must be adopted to overcome this deficiency as well as to enhance physical and other mechanical properties but in more convenient and economical method. Through many research from the past, it has been observed that addition of different types of fibres has been more effective for this purpose. This report presents the work undertaken to study the effect of steel and hay fibre on normal cement concrete of M-15 Grade on the basis of its mechanical properties which include compressive and tensile strength test and slump test as well. Although hay fibres are abundantly available in Nepal, no research have been popularly conducted here regarding the use of hay fibres in concrete and the changes brought by it on concrete’s mechanical properties. Experiments were conducted on concrete cubes and cylinders of standard sizes with addition of various percentages of steel and hay fibres i.e. 0.5%, 1% and 1.5% by weight of cement and results were compared with those of normal cement concrete of M-15 Grade. For each percentage of steel and hay fibre added in concrete, six cubes and six cylinders were tested for their respective mechanical properties at curing periods of 14 and 28 days. The results obtained show us that the optimum content of fibre to be added to M-15 grade of concrete is 0.5% steel fibre for compression and 0.5% hay fibre content for tension by weight of cement. Also, addition of steel and hay fibres enhanced the binding properties, micro cracking control and imparted ductility. In addition to this, two residential buildings were modeled in SAP software, one with normal concrete and other with concrete containing 0.5% steel fibre. Difference in reinforcement requirements in each building was computed from SAP analysis and it was found that 489.736 Kg of reinforcement could be substituted by 158.036 kg of steel fibres and decrease in materials cost of building with 0.5% steel fibre reinforced concrete was found to be Rs. 32,100.
