LORCENIS Report Summary

Project ID: 685445
Funded under: H2020-EU.2.1.3.

Periodic Reporting for period 1 - LORCENIS (Long Lasting Reinforced Concrete for Energy Infrastructure under Severe Operating Conditions)

Reporting period: 2016-04-01 to 2017-09-30

Summary of the context and overall objectives of the project

The main goal of the LORCENIS project is to develop long lasting reinforced concrete for energy infrastructures with lifetime extended up to a 100% under extreme operating conditions. At the same time, our society has to face environmental aspects (increased CO2 emissions) challenging the energy request from carbon-based sources more efficiently at short term and to move to renewable energy sources at a longer term. The LORCENIS concept with cost-efficient operation is based on an optimal combination of novel technologies involving internal curing, customized protection, repairing (healing) and self-diagnosis methodologies. The functionality of the developed concrete materials will be verified from a proof of concept (TRL 3) to technology validation (TRL 5), supported by numerical tools to capture the multi-scale evolution of damage and models for service life prediction. 4 scenarios are considered for demonstration:
S1: Concrete infrastructure in deep sea and (sub-)arctic zones: offshore windmills, gravity based structures, bridge piles, harbours.
S2: Concrete and mortar under mechanical fatigue: offshore windmills, sea structures.
S3: Concrete structures exposed to high temperature thermal fatigue: concentrated solar power plants.
S4: Concrete structures subjected to acid attack: cooling towers, biogas digester.
Moreover, LORCENIS will pave the way to standardization, analysis of cost-effectiveness and commercial potential of project outcomes within their exploitation strategy, as well as including the environmental and sustainability concerns through LCA and LCC analysis. Safety and health considerations be also addressed.
LORCENIS is a well-balanced consortium of multidisciplinary experts from 9 universities and research institutes and 7 industries from 8 countries involving 2 SMEs.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

LORCENIS is gathering the major groups of project activities in 7 work packages.
The project management (WP1) ensures efficient knowledge exchange between the partners, periodic status meetings including progress reporting.
During M1-M18, all WP2 partners were optimizing the self-responsiveness approaches tailoring the nano-additive technologies with the desired admixture properties for compatible incorporation in concrete. The most promising nano-additive candidates were upscaled and delivered to WP3 partners for successfull implementation to concrete bulk structures.
WP3 working on multifunctional bulk reinforced-concrete materials to operate under severe conditions, started with a comprehensive review of durability analyses and defined the requirements for the various exposure scenarios. The design of several concrete mixes to be used in the various exposure conditions S1-S4 resulted in two top concrete technologies to be functionalised: Self Compacting Concrete (SCC) and Ultra High Performance Concrete (UHPC). Protocols for durability tests at lab scale were defined with a standard Ready Mix Concrete (RMC) mix design used for reference.
The work in WP4 is focusing on the development of advanced software for modelling and end-of-life prediction by linking simulation approaches to launch a precise forecast model of damage development in-line with experimental validation action. Activities were carried out aiming at transfering LORCENIS metadata structure in agreement with the EMMC (European Materials Modelling Council) regarding the relevant parameters for modelling transport of aggressive ions (chlorides) in bulk concrete. Selected software components will be followed within the framework of AEST (Advanced Engineering Software Tool) and a multiscale predictive modelling workflow (MODA tables) for the selected reference material was completed. Currently, all WP4 partners are working on their models along the multiscale strategy.
WP5 started a survey on demonstrator design, building, testing and monitoring covering prototypes for each scenario identified in WP3 and each self-responsive technology developed in WP2.
In WP6, data acquisition for the Safe-by-Design (SbD) principles resulted in a decision tree (work flow) based on controlling hazards, considering European legislation. The defined methodology for LCA included inventory from all basic components of concrete and the newly developed admixtures.
The awareness and dissemination plan, the first version of the data management plan (DMP) and the plan for the Exploitation and Dissemination of Results (PEDR) have been prepared in WP7 and will be periodically updated. At the external website, the biannual LORCENIS Newsletters are published. The Advisory Board (AB) with invited experts on energy sector infrastuctures joined LORCENIS at M18.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

LORCENIS will add value to the European manufacturing sector on reinforced concrete energy infrastructure through adaptation to global competitiveness pressure by improving the technological base. The well-targeted project consortium with representatives along the value chain (product manufacturers, tool developers, energy infrastructure contractor and operators) will approach new business developments according to market needs, expected market up-take and standardization, safety and environmental requirements and needs tackled.
The scaling-up protocols of various optimized nano-additives capable of providing self-responsive ability compatible with the concrete matrix will be beneficial for the construction industry. The ambition is to withstand extreme operating conditions achieving 100% of crack healing through the incorporation of the ideal dosage of each nanomaterial with improved stability, mechanical properties, quicker self-healing activity and competitive production costs. The overall potential is very high since LORCENIS will offer a route to precisely engineer concrete for specific applications, reducing costs and increasing performance. Developing cement and concrete related nanotechnology have a sustained and important impact on the future of the construction industry enabling entirely new applications for concrete.
Tools for automatic differentiation (AEST) will significantly decreasing the workload when investigating the most detrimental phenomena concerning concrete structures: chloride ingress. Predictive modelling and the ability to handle in-service performance is an essential part of the EMMC roadmap and a vision topic of digital European future. All findings in LORCENIS will have a huge impact on the durability of energy and transport infrastructures: costs will be saved already in the design phase by simulating the behaviour of materials with different admixtures in a given environment.
LORCENIS aims to overcome any risks originating from missing knowledge or regulations and uncertainties relating to health and environmental issues. A risk assessment tool will serve to reduce potential risks from particulate nanomaterials by safe manufacturing, handling and control of exposure; specific best practice guides will be proposed. Life cycle (cost) analyses (LCA, LCC) will gain a new level of quality subsequently lowering service life expenses achieving a substantial “economical” modelling impact.
The user-friendly project website is essential to trigger dissemination and exploitation LORCENIS results worldwide towards potentially interested parties across industry groups, geographical markets and the academic community and will prepare the market take-up of the developed technology using business-oriented commercialization plans for each partner involved.
