Need for repair and rehabilitation of concrete structures Defective design of the structure. Repair is the technical aspect of rehabilitation. It refers to the modification of a structure, partially or totally damaged in appearance or serviceability. With the increase in construction activities over the past two decades, mainly in the construction sector, it has been observed that many of the structures are already showing signs of distress.

In some cases, repair measures are necessary even within a period of 5 to 10 years after the completion of the structure. This can happen due to a number of factors such as poor quality concreting materials, poor workmanship, lack of maintenance, atmospheric effects, abuse, accidents or natural calamities. Therefore, the adaptation of a concrete structure becomes necessary to extend its service life and ensure the durability of the structure. The rehabilitation provides for the restoration of the structural system as close as possible to the original position.

The worn structure must be brought into line, leveled and with the required strength so that it can be put into service without jeopardizing its safety and usefulness. Before finalizing any plan for the repair and rehabilitation of a worn concrete structure, the expert in question must be fully aware of the causes of the danger, the extent of damage to the structure and the current state of the concrete in the structure. The extent of distress should be classified so that reparation schemes can be formulated according to distress in a particular structural element. Pre-repair assessment and evaluation of a structure are a prerequisite for developing effective repair schemes.

Once repairs have been carried out on a distressed structure, post-repair evaluation and evaluation of the structure can be carried out to verify the effectiveness of the repair. Such a “task of evaluation, evaluation and execution of repair work certainly has to be entrusted to an 'expert and specialist' in the field in order to make repairs effective and durable. One such expert group is STANDARD REHABILITATORS PRIVATE LIMITED. In order to collect the data for the design of the structural rehabilitation of the Shroud Chapel, an extensive on-site research campaign was carried out.

ICC Acceptance Criteria 125 (AC-12 and AC-178) establish the minimum acceptable criteria for durability, structural performance, and inspection criteria for any CFRP coating system to be considered suitable for structural rehabilitation applications. The repair process for internal strengthening does not require the excavation of a trench, therefore, the FRP composite lining becomes a trenchless structural rehabilitation. Since repair %26 the rehabilitation of a structure expects to correct damaged areas, it is therefore obvious that repairs need guaranteed inputs of correct material, quality workmanship %26 finally, but at least the right system or specification to be adopted gradually. However, most of these problems can be solved by perfect analysis, followed by repair and rehabilitation.

The results of this durability study indicate strong potential for the CFRP coating system to work well as a long-term solution for pipeline rehabilitation. In the rehabilitation function, an inserted liner separates the contents of the pipe from the inner diameter of the steel host pipe, effectively breaking the cycle of corrosion and erosion, which is one of the main causes of wall loss, and cuts off the supply of corrosive fluids and bacterial nutrients, which is the main cause of localized corrosion. Below, the infographic presents some of the chimney repair and rehabilitation projects they have carried out. For any repair %26 rehabilitation work, it is always better to trust the manufacturer in the various aspects of the material% 26% its suitability for that particular type of work.

As FRPs are non-corrosive and have high specific strength and modulus values compared to their density, their light weight, custom design, acceptable deformability and excellent formability allow the manufacture of new elements and the structural rehabilitation of existing parts made of traditional materials materials. As already evidenced in the previous text, at present and at European level, no well-established design and detail calculation methods have been developed that cover all techniques for the on-site use of composite rehabilitation systems in wood and concrete structures. For the rehabilitation of external surfaces of metal pipes that have suffered corrosion due to (i) acid attack of the environment or acidic soils in which the pipe is buried or (ii) alkaline environments when the pH value exceeds 10.5, reference should be made to Section 12.3 of this chapter. All fiber types are available in various fiber forms and architectures, corresponding to the manufacturing processes, but also according to the requirements of FRP composites for structural rehabilitation.

SRPL is also expanding consulting services to find intellectual solutions for repairs and rehabilitation of CCR structures by performing appropriate NDESTRUCTIVE TESTING using the latest state-of-the-art non-destructive testing equipment. However, the development of appropriate design guidance standards is much more advanced in the case of the rehabilitation of concrete structures than for wooden structures. . .
