Recently, we have experienced unusually high temperatures in the United Kingdom, which spurred me to write a few lines about Concrete Batching and storage of materials. I have tried to keep it brief, simplistic, and to the point in discussing one aspect of Hot Weather Concrete. Still, further information is already readily available elsewhere. So… Continue reading Hot Weather Concreting – Batching Plants

Self Compacting Concrete – A Lesson in Concrete Technology
A well-known professor of concrete technology stood before his class and had some items in front of him. When the class began, wordlessly he picked up a large empty mayonnaise jar and proceeded to fill it with rocks, rocks about 50mm in diameter. He then asked the students if the jar was full? They agreed… Continue reading Self Compacting Concrete – A Lesson in Concrete Technology
Greener / Commercially Viable Concrete
in Accordance with BS 8500-1:2015+A2:2019 I have, over the last couple of years, been privileged to be part of Committee B/517 for British Standards, Ltd. which helped to shape the changes for the UK Marketplace for the specification of concrete. The specifier is offered five ways to specify concrete within the standard specifications for designated,… Continue reading Greener / Commercially Viable Concrete
Highly Air Entrained Concrete
A simple approach to produce a highly air-entrained concrete/mortar. Essentially this is a lightweight material produced by incorporating a specialised surfactant to produce a highly air-entrained concrete by mechanical mixer action into a base mix of cement mortar (with or without coarse aggregates). The resultant entrained air bubbles reduce the density of the base mix… Continue reading Highly Air Entrained Concrete
Thoughts on ultra-high performance fibre-reinforced concrete hereafter referred to as “UHPFRC”
Many articles have been written over the years regarding UHPFRC, to my knowledge, it’s been around under certain guises since the late 1980s. Proprietary designed materials from the likes of BCV® (Vinci Group, France), CERACEM® (SIKA, France), CRC® (CRC Technology, Denmark), DENSIT® (DENSIT® ApS, Denmark), DUCTAL® (LaFarge and Bouygues Group, France), EFFIX® (Italcementi Group, France),… Continue reading Thoughts on ultra-high performance fibre-reinforced concrete hereafter referred to as “UHPFRC”
