Solid Density of Building Materials: Assessing Purity of Powders and Open Porosity of Concrete Components
The density of building materials such as cement and bitumen plays a significant role in production and performance. Purity of powders and the open porosity of cured pieces are important material characteristics that can be assessed from solid density measurements. Tapped density via the Autotap and skeletal density via the Ultrapyc 5000 give extremely accurate volume measurements that are required for the building industry and can be correlated to purity, porosity, and flow.
UK productivity hindered by digital skills deficit – report
This is a bit of a nebulous subject. There are several sub-disciplines of 'digital skills' which all need different approaches. ...
