Abstract: During July and August 2004, BASF Construction Chemicals Spain and the University Polytechnic of Catalunya (Barcelona) began a study with the aim of comparing durability properties between conventional concrete, standard SCC and steel-fibre reinforced SCC (SFR-SCC), when they are used for the construction of thin elements as well as thin, reinforced walls.
To make this study representative, concrete was produced in a conventional batching plant and delivered by lorry to the University, where large-scale application was done, concreting thin, reinforced walls using a concrete pump. Concrete homogeneity by ultrasonic device, cracking distribution, strength evolution, water penetration, chloride penetration, CO2 frontline evolution and capilliary absorption were tested on all the three concrete types evaluated from samples extracted directly from the applied concrete. Results observed showed an improved durability for SCC and SFR-SCC against conventional concrete in practically all parameters checked.
