The Swedish Cement and Concrete Research Institute was founded in 1942. Two people contributed substantially to the realization of the plans: Professor Lennart Forsén and the industrial executive Dr. (h.c.) Ernst Wehtje. Mr. Forsén had a long experience within the cement area from both the industry and the university and Mr. Wehtje was the managing director for the cement producing company that today is called Cementa. The Institute and its building at the campus of KTH Royal Institute of Technology in Stockholm were enabled through a generous donation from twelve companies to Mr. Wehtje to celebrate his 50thanniversary. This report summarizes the Institute’s first 70 years.The report has partly a thematic and partly a chronological order. In the first Chapters, the early history is told, the Institute building is described, and the research financing is discussed. Subsequently, there are four chapters describing the 1970s, 1980s, 1990s, and the first decennium on the 21st century. Every chapter author in this part writes through his personal experience from that time. These chapters are followed by chapters describing the continuation education activities and some statistical data from the Institute publications. The report is concluded with lists of the 308 publications that are included in the Institute’s highest publication series.Since this report contrary to other Institute reports neither is a research report nor a state-ofthe-art report, there are no decisive conclusions. We may, however, note that the Institute is prospering and today (December 2012) is larger than ever. Man has used concrete in more than 2000 years but new research questions are still put which have to be answered through continuing research. The concrete research is mainly applied research and through its role between industry and university the Swedish Cement and Concrete Research has a stage to act upon
