ADCORE project has been financed by ACCIÓ project number ACE011/20/000025.
There is a current trend to use synthetic fibres in concrete to improve shrinkage. This trend, which is the one that is used in most of the on-site applications, has led to the appearance of new trends regarding the use of other types of additives in concrete, such as calcium oxide, magnesium oxides, calcium and magnesium sulphates, etc.
Expansive additives are widely used to compensate for the drying shrinkage of cement-based materials to prevent them from cracking. However, the expansion of the conventional ettringite-bearing expansive’s additive is strongly dependent on moisture curing and generated mainly at an early age. Therefore, it may not work correctly in concrete without sufficient water supply or long-term shrinkages.
The ADCORE project aims to establish the conditions for the valorisation of industrial and urban waste as additives high value-added chemicals for the formulation of compensated shrinkage concrete. These new additives will have the advantage of being less sensitive to the effects of the application compared to those currently used.
