The project aimed to establish whether new CSA based powdered accelerators can provide the setting and early age strength development required when sprayed concrete contains GGBS at a replacement level of between 70% and 80% and to evaluate the impact on the durability of the resultant sprayed concrete.
This project was a collaboration between Professor Chris Goodier, Professor Sergio Cavalaro and Zhi Hu of Loughborough University; Michael Sataya of Ove Arup and Partners International Ltd; Dr Chris Peaston of Peaston Concrete Consultancy; John Reddy of Ecocem; and Stuart Manning of Shotcrete Services Ltd.
