The construction industry in the U.S. is anticipated to witness significant growth over the forecast period on account of growing inclination towards industrial development and rising demand for commercial constructions in the country.The market is expected to expand at a high growth rate in the upcoming period owing to the rise in demand for less maintenance of building and infrastructure. To enhance the lifespan of buildings and structures, self-healing concrete offers feasible solutions, thereby gaining traction in the construction market.Traditional concrete and its related substances are subject to crack over a period of time, resulting in increased tension on walls and beams. To support the crack repairs and reduce maintenance of the buildings, self-healing concrete is used in the construction process. This specialized concrete produces limestone with the help of bacteria present in the concrete substances.The rise in demand for eco-friendly and sustainable constructions with high endurance is expected to drive the demand for self-healing concrete. However, nowadays, the proportion of non-hardening cement in the construction process is less, along with growing trends of fast construction. Moreover, unskilled labor is scaling the proportion of natural cracks in walls and columns of buildings. Thus, the service and repair activities of the construction are likely to ascend the demand for self-healing concrete over the forecast period.Report Coverage & DeliverablesPDF report & online dashboard will help you understand: Competitive benchmarking Historical data & forecasts Company revenue shares Regional opportunities Latest trends & dynamicsForm Insights In 2019, the vascular form of self-healing concrete accounted for the largest revenue share of 62.18% and is expected to witness the highest growth over the forecast period. This form is used when a series of tubes filled with concrete healing substances are passed through the concrete structure from the interior to the exterior of the building walls. These tubes need to be placed at anticipated locations wherein the crack is likely to occur, which makes the system non-pervasive.Capsule-based self-healing concrete is expected to witness notable growth over the forecast period owing to the ease of convenience the technique offers for large-scale usage. These substances when poured into the gaps react with air or another embedded concrete matrix and create hardened substances that fill gaps in walls and other building components.Bacteria-based capsules for self-healing are preferred in the market as these have an extended lifespan and can stay active for over 100 years. Whereas the chemical-based capsules may lose healing capabilities over a period of time and thus are less popular in self-healing applications. Cylindrical shaped capsules take up larger areas and can be built at higher lengths, and thus have a better healing mechanism than spherical shaped capsules.Vascular-based healing technology is used when a series of tubes filled with concrete healing substances are passed through the concrete structure from the interior to the exterior of the building walls. This technology can be implemented through a single or multi-channel approach depending on factors, including building shape, concrete strength, and a number of healing agents.Application Insights The infrastructure application segment held the largest share of 58.3% in 2019 in terms of revenue and is likely to witness significant growth over the forecast period. The rising initiatives by the construction companies to commercialize the product for the durability of infrastructure by collaborating with the product development companies are expected to ascend the product demand.Industrial construction needs to withstand harsh mechanical impacts owing to heavy-duty operations, including carriage of vehicles, operating heavy machinery, and heat treatments that require rigid surfaces with durability. Hence, self-healing concrete is expected to gain traction in industrial construction since these structures need strong resistance to various physical and chemical factors to comply with the technological requirements for a safe and convenient surface to carry out industrial operations. To learn more about this report, request a free sample copy The use of self-healing concrete in residential and commercial buildings is expected to help reduce the permeability of the construction and manage cracks. Foundations, grade slabs, floorings, basements, and walls are the key applications areas where reinforcement of the concrete is required to increase the lifespan of these structures.A rise in the number of construction activities for office buildings, institutions, healthcare centers, education centers, hotels, restaurants, and other commercial complexes is anticipated to provide growth prospects for the market. Furthermore, the adoption of technical changes in building practices for enhancing the durability of the structures is likely to support the market growth on a positive note.Regional Insights Europe dominated the global market in 2019 with a revenue share of more than 53.0% and is expected to witness significant growth in the projected time.

- Implementing innovative and sustainable solutions for extending the service life of concrete structuresThe search for smart self-healing materials and preventive repair methods is justified by the increasing sustainability and safety requirements of structures. The appearance of small cracks in concrete is unavoidable, not necessarily causing a risk of collapse for the structure, but certainly accelerating its degradation and diminishing the service life and sustainability of constructions. That loss of performance and functionality promote an increasing investment on maintenance and/or intensive repair/strengthening works. The critical nature of such requirements is signified by their inclusion as priority challenges in the European Research Program.The first focus of this proposal is to compare the use of self-healing capabilities of concrete with the use of external healing methods for repairing existing concrete elements. Despite the promising potential of the developed healing technologies, they will be real competitive alternatives only when sound and comparative characterization techniques for performance verification are developed, being this SARCOS's second focus. The third focus deals with modelling the healing mechanisms taking place for the different designs and with predicting the service life increase achieved by these methods. SARCOS COST Action will be lead by research institutions searching on different self-healing technologies and repair solutions for extending service life of new and existing concrete structures, with high expertise in developing characterization techniques. Also specialists on modelling healing mechanisms and experts on numerical service life prediction models contribute for the Action's success. This composition provides a solid framework to advance in implementing innovative and sustainable solutions for extending the service life of concrete structures. About SARCOSOur Action (CA15202), Self-healing As preventive Repair of COncrete Structures, started on 30 September 2016 and will last until 29 September 2020.OverviewSelf-healing of cement-based construction materials represents a valuable and cutting edge asset because of their inborn capacity to repair damages once they occur.External repair methods based on incorporating “healing promoter additives”, compatible with the existing cementitious substrate, are also innovative solutions beyond the know-how for the repair and rehabilitation of the existing building and infrastructures’ stock.These preventive repair solutions aim at extending the service life of structures and infrastructures without lost of performance.SARCOS Action deals with these new concepts and advanced solutions, from the design of smart “healing promoter additives” to the standards definition for performance evaluation, involving a breakthrough scientific research.ObjectiveTo provide a framework to advance the implementation of innovative and sustainable solutions for extending the service life of concrete structures.About COSTCOST (European Cooperation in Science and Technology) is a pan-European intergovernmental framework.

- Special Issue "Self-Healing Concrete and Cement-based Materials" A special issue of Materials (ISSN 1996-1944). This special issue belongs to the section "Construction and Building Materials".Deadline for manuscript submissions: 31 December 2021. Special Issue InformationDear Colleagues,Deterioration of concrete is often associated with the ingress of external agents, and thus the presence of cracks can dramatically shorten the service life of conventional concrete structures. However, concrete crack is inevitable as it is caused by many different reasons which cannot be controlled even by experienced concrete engineers and workers. One of the possible solutions to mitigate cracks in concrete is autonomous healing, which relies on activities other than those of cement-based materials. Autonomous healing has been gaining the interest of many researchers who have explored the effectiveness of bacterial crystallization, encapsulation/vascular, expansion polymer/crystal, electrodeposition, shape memory alloy, fibers, and nanoparticles toward the self-healing of concrete.In addition to studies on self-healing methodologies, applications of self-healing are also actively performed. These include crack detection through image-based machine learning and self-sensing concrete with conductive additives or crack repair quantification method through ultrasound wave or X-ray tomography.In this Special Issue, recent progress in the development of self-healing concrete and cement-based materials and their application to construction, repair, and coating will be discussed. The articles in the Special Issue will cover, but will not be limited to, the following topics:Self-healing concrete methodologies using additives, bacteria, microcapsulesSelf-healing mechanism and modelingAutogenous and autonomous self-healingApplication of self-healing techniques to repair, coating, etc.Evaluation and monitoring of self-healingIt is my pleasure to invite all researchers and engineers having interests in self-healing concretes and their applications to submit a manuscript for this Special Issue.
