The building materials laboratory is dedicated to testing and practical work on materials used in the building sector, namely the application of some test methods on the plaster, paste rheology studies and the development of new materials in the field of traditional building.
This laboratory is equipped with the following apparatuses:

• Electric sand equivalent shaking machine
• Apparatus of shrinkage limits in a box

The chemistry laboratory is equipped with the following apparatuses:

• Soxhlet Wood Extraction Apparatus:  The Soxhlet extractor is an ingenious glass device for extracting a substance. It is mainly used in the preparation of samples before analysis, and in the determination of fat in water, detergents;
• Rotary Evaporator:  The rotary evaporator is a device used in chemistry to rapidly distil solvents, in order to partially concentrate a solution or to concentrate to dryness (remove all the solvent) a solution or a suspension;
• Polarizing A1 microscopes: The polarizing microscope is a tool for observing thin sections of rocks used to determine their nature and mode of formation, in addition to an observation at other scales. It allows the identification of minerals and the determination of the texture* of rocks;
• pH meter: A pH meter is an instrument, often electronic, for measuring the pH of a solution. The pH meter generally consists of an electronic box for displaying the numerical value of the pH and a pH sensor consisting of a glass electrode for the measurement and a reference electrode. Its operation is based on the relationship between the ion concentration (pH definition) and the electrochemical potential difference which is established in the pH meter once immersed in the studied solution;

3D printing is an innovative manufacturing process that naturally finds its place in the world of crafts. Already widely used by professional craftsmen in complementarity of traditional methods, this revolutionary technique has many advantages, especially in terms of accuracy, cost or customization possibilities.

3D printers are gradually being used by our technology lab. The favorable evolution of their performances makes it possible to consider them as complementary means of obtaining educational prototypes or models.
 
Today, it is possible to print in 3D an extremely vast range of materials and the technological advances are dazzling.

3D printing, also known as "additive layer manufacturing" or "additive manufacturing", makes it possible to physically render 3D objects, from the CAD model, without tools and in a much shorter time than by conventional techniques.

The 3D digital model is drawn with a volume modeler (Rhinoceros, 3D studio Max, Spaceclaim ...) and usually exported in STL format. These printers then proceed to the realization.

The laboratory of the Academy is also equipped with a 3D scanner that is based on a method (3D digitization) which allows to measure in a contactless manner the shapes and the colour of the surface of an object to create an IT replica for the purpose to archive it, edit it or duplicate it with 3D printing.
