Typical concrete comprises cement, water, gravel and sand. While this mixture makes the substance hard and strong, it does not promote flexibility. Thus concrete is brittle and prone to cracks if too much weight is applied. What if it could be more bendable?
A new project to transform building facades into ‘biological computers’ made up of ‘digestive’ bricks that can create useful products from waste has been launched at Newcastle University.
Whether the ground floor of a house is suspended or filled, it will include either a solid slab or an oversite layer of concrete laid on compacted hardcore directly on the ground. Both hardcore and soil are potential sources of sulfates and other chemicals harmful to concrete. This programme investigates the hardcore components and soil conditions likely to contain sulfates, explains how concrete is affected by sulfate attack and looks at methods used to prevent such damage.
The replacement of the old British Standard BS 6651 with BS EN 62305 will have a significant impact on the design and installation of lightning protection structures. This programme explains why the new standard has been adopted and discusses its key points. The procedures associated with the new standard are examined, while Surge Protection Devices (SPDs) and Lightning Protection Zones (LPZs) are explored in detail.
We start by hearing how the UK's network of 200 fundamental benchmarks all stem from a single 'mother' benchmark at Newlyn in Cornwall. We show how the network expanded and we learn why now, in this highly technical modern age, the humble benchmarks' days are over.
Dominated for more than 100 years by light industry, the 2.5 km2 site was contaminated and its waterways choked. Beginning with the ODA's head of infrastructure, Simon Wright, we learn about the scale of the task faced by Atkins, the firm charged with leading what was to become the most comprehensive enabling works ever undertaken in the UK.
Developed by a wide range of industry representatives over a ten-year period, its assessments are becoming an essential benchmark for many civil engineering projects large or small and this programme looks at some of the main components of the scheme.
