Abstract:This paper presents the result of the work performed by the Norwegian Defence Estates Agency on the development of a low cost ultra high performance concrete (UHPC) for protective structures. The aim has been to develop a high strength concrete, about 150 MPa, based on commonly available materials, with workability suitable for traditional construction practice, and produced at a reasonable cost. The documentation program includes studies of the hardened properties of the concrete, in addition to full scale production tests, full scale realistic impact tests and large-scale beam tests. It is verified that concrete with a 2%day compressive cube strength of 150 MPa, based on commonly available high quality materials, may be produced without any major modifications to standard production facilities or procedures. For practical application, the autogenous shrinkage of the concrete may be a critical property whenever the hardening concrete is subject to restraint. The penetration resistance of UHPC is significantly better than normal strength concrete. Increasing the concrete strength from 30 MPa to about 200 MPa the penetration depth will be reduced by a factor of approximately 2.5.
