LABORATORY / INNOVATION

In the Laboratory/Innovation area of TESELA we characterise, study and develop all types of works of art and construction materials, whether traditional, advanced or sustainable.

The use of a wide range of equipment enables us to carry out specialized technical-scientific reports based on the compositional characteristics, intrinsic properties and uses of each material. Moreover, we carry out material development and research for companies that manufacture building materials (limes, mortars, ceramics, concrete, paints, cements, etc.), and consulting to professionals from the field of construction, rehabilitation and restoration (architects, quantity surveyors, engineers, master builders, restorers, etc.), and to experts in archaeological and archaeometric studies.

ANALYTICAL TECHNIQUES

In TESELA we work with a wide range of high resolution analytical instruments that enables us to identify and characterise any material. In order to do this, we use the equipment available at the University of Granada and its technological centers, which makes it one of the most modern and prestigious research centers in our country. Among them we highlight:

  • Optical polarized, fluorescent and confocal light microscopy
  • Scanning, environmental and high-resolution transmission electron microscopy with microanalysis (EDX)
  • X-ray diffraction and X-ray fluorescence
  • Thermogravimetry
  • Structural analysis and determination (EAN; Chromatography; FTIR; RAMAN)
  • Porosimetry by mercury injection and gas adsorption
  • Ultrasounds
  • Carbon 14 dating
  • Petrophysical tests
  • Colorimetry and spectrophotometry
  • Laser granulometry
  • Accelerated decay tests

Within the laboratory and innovation area we have defined two main lines of work, on the basis of the type of materials:

With regard to TRADITIONAL MATERIALS found in historical-artistic heritage, conservation-restoration interventions have the objective of maintaining the cultural, historical and aesthetic integrity of the damaged cultural property. At the same time, they guarantee its physical stability and longevity. In order to achieve this, it is necessary to characterize the materials that constitute the good, as well as to investigate the pathologies and understand the causes of deterioration, thus enabling the company to provide the basis for a proper intervention.

In terms of SUSTAINABLE BUILDING MATERIALS, our objective is to create a new line of materials oriented towards bio-construction, which is traditional (regarding the old criteria of construction ) but modern at the same time, from a technical point of view. In addition, we want to ensure a link between the criteria of sustainable architecture and the principles of restoration. It is well known that the choice of suitable materials compatible with the original, reversible and durable ones is an essential condition to guarantee the success of rehabilitation and restoration works. Moreover, the use of more environmentally friendly materials (e.g. plant and mineral derivatives materials, less contaminant and more energy efficient) would enable restoration projects to be in accordance with environmental and economic criteria.

LINES OF WORK

Traditional and sustainable materials (Raw materials: stone materials, aggregates, pigments, etc. and Prefabricated materials: mortars, rammed earth, binders, additives, paints, ceramics, etc.)

  • Characterisation through testing procedures
  • Studies applied to specific uses
  • Feasibility studies for specific uses
  • Standardized tests
  • Consulting about new formulations
  • Consulting about benefits and uses
  • Design of materials based on traditional binders (lime, gypsum, clay) and organic materials as additives
  • Sale of know-how
  • External R & D & I service to companies
  • Evaluation of restoration and cleaning products (consolidants, water repellents, etc.)
  • Authentication of artworks

Study and diagnosis of building pathologies (civil works, restoration, etc.)

  • Visit to construction project in question
  • Identification of causes
  • Evaluation
  • Expert report
  • Proposed solutions
  • Pre-intervention studies aimed at the conservation or restoration

In terms of ADVANCED MATERIALS, the research and development of new technologies applied to this sector open a range of possibilities for its use in the design of new products based on binders for construction and other sectors, as well as for the optimization of existing materials (economic, energy, sustainable, mechanical, ergonomic, etc.). First-hand knowledge of the raw materials (characteristics, properties, new applications and uses) offered by the market, together with a research and technological surveillance work in this field, provides us with a comprehensive knowledge of technologies and new materials at a multi-sectoral level (not only under construction), enabling us to be at the cutting edge of the development of new advanced materials.

LINES OF WORK

Advanced materials: cements, limes, gypsum, aggregates, additives, pozzolans, organic additives, etc. (for construction, decoration, heritage, street furniture, etc.)

TESELA is able to show in the industrial sector the great importance of keeping up to date on the new advances in formulation, sometimes backed up by suppliers proposals.. Our intention is to put in value the advantages they offer, as well as to enable new ways of development. Therefore, we offer the factories or production centers the means and the knowledge that enable them to reach the expected objectives, so that they can offer to the market products of defined benefits guaranteed the quality of the same and achieving the improvements in their competitiveness, having present its productive processes.

In TESELA, we always keep in mind in mind the uses and characteristics of the sector, therefore we have the specific instruments, and we have the support of analytical techniques that enable us to study the material, taking its analysis even to the characterisation of its composition and internal structure, enabling us to approach the work from a multidisciplinary approach, fruit of the combination of all lines of work in materials, that we are able to cover.

In advanced materials our proposal is reflected in the following sections:

  • New materials research
    Study of the requirements, tools and traceability in order to carry out research lines.
    Implementation of the different stages that lead us to the characterisation of a new material or product.
    Evaluation of the impact on the sector for planned uses and new applications to be developed.
  • Development of own know-how
  • Standardization
    Drawing up reports on the approval of additives and raw materials in existing designs or formulations, which includes the synergy of components to assess their full compatibility:
    – Aggregates, fillers, pozzolanic additions, etc.
    – Hydraulic and aerial setting binders.
    – Organic and inorganic additives.
  • Characterisation by standardised tests
    Assessment of the physical-chemical properties of the materials for their endorsement as standardised materials according to the regulations and the internal controls in force.
  • Studies applied to specific uses
    We perform an evaluation of the compatibility between different materials according to their intended use and to the availability of resources needed for their implementation in situ.
  • Feasibility studies for specific uses
    We perform analyses of the materials behaviour according to the stipulated properties and uses, depending on the environmental conditions, available machinery, and the influence of other external agents.
  • Formulation advice
    We offer consulting for the optimization of formulations, with a global vision that contemplates the productive process, uses and requirements. Performed gradually, this activity aims to promote continuous and advanced materials improvement.
  • Consulting on benefits and uses
    Based on the materials description and characteristics, we assess their suitability for the proposed use.
