Cementos Portland Valderrivas

Grupo Cementos Portland Valderrivas is the largest cement group, leader in cement production in the Spanish market. Since its birth in 1903, it has undergone continuous development and currently has factories in three countries: seven in Spain, three in the USA and one in Tunisia. Its production capacity amounts to 15.8 million tons per year. The contact person is Mr. German García.

Cementos Tudela Veguín S.A.

Pioneering company in manufacturing a novel product in Spain: artificial cement. Currently, it continues to be a benchmark in the production of cements and limes at an international level, betting on innovation and absolute commitment to nature. This company would provide the granulated blast furnace slag to be used in the project. The granulated slag is obtained by sudden cooling of the liquid slag, dropping it on water spray systems. One of the most widespread applications of granulated slag is the manufacture of cement. Although, for its use it must be dried and subsequently ground to a fineness similar to that of Portland Cement. This product as such is produced and marketed by Cementos Tudela Veguín S.A. The contact person for this company is Mr. Ricardo Fe.

Sika Spain

Leading company in the manufacture of construction chemicals. Specialists in sealing, gluing, waterproofing, repair of structures. Sika is also an expert in the manufacture of mortar and concrete additives. An additive is a product that is incorporated at the moment of kneading the concrete or immediately afterwards, in amounts not exceeding 5%, in order to modify the properties and characteristics of the mixture in the fresh and / or hardened state. IRINEMA will inform the company of the chemical characteristics of this type of materials and they will provide a series of additives that are compatible with these systems in order to improve the workability of the designed geopolymer. The contact person is Mr. Ramiro García Navarro.


Spanish public research body of excellence in energy and environmental matters, as well as in multiple cutting-edge technologies and in many basic research areas. The contact persons of this organization will be Dr. Elena Torres Álvarez from the Department of the Environment and Dr. Gabriel Piña Lucas from the Department of Energy and director of the Low and Medium Activity Waste Unit. Both are experts in low and intermediate activity waste management, which would be very beneficial for the project, since they will give support in the preparation of the resin where a solution will be prepared with the elements of interest previously defined and it will be loaded in the ion exchange resin for later use.


The contact person for this institution will be Dr. Isabel Sobrados de la Plaza, PhD in Chemistry, in the Department of Energy, Environment and Health. She is an expert in the study of new materials for lithium batteries, post-lithium and fuel cells and also in Nuclear Magnetic Resonance Spectroscopy of solids, both in ceramic compounds: crystallochemistry and in ionic conductors: Lithium ion mobility. Dr. Sobrados is the scientific manager of the Nuclear Magnetic Resonance unit. The Pulsed Nuclear Magnetic Resonance Spectrometer is an AVANCE II (Bruker) with a 9.4Tesla magnet, which has MAS probes for rotation at different speeds that allows studying of different nuclei. In this project, Dr. Sobrados will be in charge of characterizing the final product immobilized in the geopolymer through NMR of nuclei 29Si and 27Al. Similar studies will be carried out for the final product immobilized on the Portland cement base material. This would be very useful to complete the characterization of the geopolymers and traditional Portland cement system with the immobilized residue.

The university of Sheffield

The contact person will be Professor John L. Provis, PhD in Chemical Engineering at the University of Melbourne (Australia). He is currently working in the Materials Science and Engineering Department. Professor Provis’s research focuses on the development, characterization, and exploitation of advanced and non-traditional cement and concrete technologies. He has worked and is working on many projects related to geopolymer and alkaline activated binders, either for use in construction, infrastructure or as waste immobilization applications. Professor Provis is responsible for the group and the cement and concrete laboratory. In this laboratory there is a Haake Viscotester 550 rheometer, which will allow to study the viscosity and fluidity of the geopolymer paste and to study the mechanism of action of the additive. This will be very interesting to check the compatibility between the additive and the geopolymer.


The contact person will be Professor María Cruz Alonso Alonso, PhD in Chemistry, in the Construction Department. Specialist in cementitious materials, mortar and concrete design, durability in aggressive environments, extensive experience in corrosion of steel in concrete and prediction of the useful life of reinforced concrete structures. Professor Alonso will collaborate in the design of leaching tests to asses the stability of the geopolymer matrix and evaluate the leaching behavior of the geopolymer / resin mixture.
