My work aims to make concrete more durable and environmentally friendly. This not only enhances structural performance but also helps to contribute to creating a circular economy.
Professor Kypros Pilakoutas
Kypros Pilakoutas (BSc (Eng), ACGI, DIC, PhD, DSc) is the Professor of Construction Innovation in the Department, the Managing Director of the Centre for Cement and Concrete and the Leader of the Concrete and Earthquake Research Group.
He is also the Director of two technology spin-out companies.
He completed his BSc(Eng) in Civil Engineering (1984) and PhD (1990) in Earthquake Engineering at Imperial College London and worked in construction for two years.
He joined the Department in 1991.
- Research interests
With over 30 years’ research experience and over 400 research publications, he focuses on structural concrete, FRP and fibre reinforcements, structural repair, construction innovation and earthquake engineering.
His research aims to make concrete more durable and environmentally friendly by replacing some of the components used in its manufacture with recycled materials or those that require less energy to produce.
Kypros has developed several new types of concrete reinforcing products, including:
- Fibre Reinforced Polymers (FRPs) made from glass and carbon (also used in sports and aerospace), as well as basalt fibres (made from stone), and metal straps (as used for packaging) for the seismic strengthening of buildings in seismic regions.
- A metal band-based shear reinforcing system for flat slabs.
- Rubber, steel wire and textile fibres from post-consumer tyres.
Kypros has many years’ experience in managing European Research projects and has successfully coordinated/co-investigated 10 EU funded collaborative projects, including:
- EU Marie- Curie ITN projects - Confibrecrete, En-Core and Endure
- FP6 STREP project ‘Economical and sustainable pavement infrastructure for surface Transport’ (EcoLanes - 2006-09: 11 partners from 6 European countries)
- FP7 project ‘Innovative use of all tyre components in concrete’ (Anagennisi – 2013-2017: 17 partners from 7 European countries).

- Research group
Earthquake Engineering Group
This project aims to develop:
(1) an advanced understanding of the mechanisms behind the fibre-matrix compatibility in controlling cracking/spalling of concrete and (2) a novel, sustainable, cracking/spalling-controlled geopolymer natural FRC and a new technique which modifies the surface properties of natural fibres to enhance their bond with the cementitious matrix.
The aim of the project was to develop, an innovative, integrated and efficient framework for multi-hazard seismic risk assessment and disaster mitigation in developing countries. Earthquake related intelligence were obtained from smart devices in real-time for the first time and integrated in to the framework.

Casting of concrete elements is still done manually.
This project will investigate robotic placement of concrete.
The main aim of this research is to develop a safety and design philosophy that accounts for the long-term behaviour of RC structures. This will require use of structural reliability theory as well as uncertainty modelling.
The project will investigate this technique both experimentally and analytically and develop models for its application in vulnerable buildings.
