Fire resistance is one of the attributes that distinguishes concrete compared to other materials such as steel or aluminium – but concerns are often raised regarding the fire resistance of UHPC. The short and simple answer to those concerns is that it is quite possible to design a UHPC with a fire resistance that is … More Fire resistance – is it a problem for UHPC?
We often get questions concerning what is possible to achieve with CRC i2®, and what process is required to get started – in short the user’s guide to using CRC i2®. In this post, I’ll try to address some of the general issues. For each individual project, there are scores of specific questions: ‘How … More Users 10 step guide to CRC i2®
Can concrete bend? No, of course not!! … or can it ?!?! Several years ago, during the installation of a specially designed staircase, I received a call from the building site: The front end of two of the element plates did not align properly, and could not be aligned by simple adjustment of the … More Cold bending CRC i2®
I am often asked why we use fibres, since we also use conventional rebars. The answer is crack-control and ductility. Ductility was one of the key elements when Hans Henrik Bache developed CRC in 1986. The high strength matrix had already been developed some years earlier, when he invented and patented DSP-materials (Densified Cement/Ultra-fine … More CRC ductility
When discussing potential projects, I am often asked what surface expression to expect of CRC i2® elements. It is a very simple question – but not as simply answered. CRC i2® is a unique cement-based material, and as conventional concrete and other natural materials, variations in colour and texture should be expected, and should be … More Surface aesthetics of CRC i2®
