CFRP Plates for Strengthening Concrete Structures Technical Data – Tensile Modulus

A review of the current available technical data sheets for  Carboplate from Mapei, CarboDur from Sika and weber.tec force from weber, show that there are a variety of different ways that technical information are presented and in general terms highlights how care needs to be taken when checking equivalent performance of CFRP Plate Bonding Products for use in flexural strengthening reinforced concrete structures.

Reading Bridge to be strengthened using CFRP Composites

The project to strengthen Reading Bridge has been secured by Volker Laser, it involves the use of foam concrete to infill some of the approach spans either side of the river, composite CFRP plate bonding to the under side, Near Surface Mounted Reinforcement to the top surface, concrete repair and bridge deck waterproofing.

I graduated from Surrey University with Civil Engineering Degree which included a sandwich year working for Specialist Piling Contractor, Cementation. My first post graduate role was with Gifford and Partners working mainly within bridge design and assessment, although I did also design the hull of a Hovercraft at one stage! I spend my last year with Giffords seconded to Hampshire CC working as a resident engineer for the bridges on the Bentley Bypass. As the project came to an end I decided to look for a more commercially focused role and started working for the global specialist construction materials manufacturer Sika. Having started at the grass routes level within the company I progressed, via several development roles, to running the UK ‘Contractors’ Business Unit with a gross turnover of approx £16m. In Nov 2013 I left Sika and after being self employed for a few months I established Structural Refurbishment Solutions Ltd (SRS Ltd) as a consultancy specialising in Technical Sales and Marketing Strategy Support, with a focus on structural refurbishment such as concrete repair, structural strengthening, flooring and waterproofing.
