MODERN CONCRETE AND DURABILITY ISSUES There’s a lot of research on the ancient Roman concrete, solid examples of which stand to this day. During 2017 there was a good deal of excitement at the newly-published discovery that Roman concrete actually ... Read More

Markham – adding life to concrete Following on from our recent webinar “Corrosion around Corrosive and Marine Environments” with Dr Jon Belkowitz of Intelligent Concrete, here are Doug Hamlin and Hayden Prestidge to cover some of the key questions ... Read More

SCIENCE MEETS HISTORY Concrete, as you know, is one of the most prolifically used construction materials on the planet. We could say a few words about its longevity (and how that counterfacts its alleged carbon footprint). Or we could talk ... Read More

So you’ve heard about concrete hydrogel treatments? Maybe you’re interested in what they can do for concrete permeability or remediation. But you haven’t seen any good reasons to use hydrogels in construction. Maybe you think they’re an added cost? Maybe ... Read More

Have you ever observed the tension or conflict in a construction project, between the short-term cost or time constraints, and the long-term durability of the structure? ‘Cutting corners’ may achieve the immediate requirements of the contractor and the client, but ... Read More

Love it or hate it, concrete is an amazing thing. Versatile, economical, durable and robust – no wonder concrete is the most widely used material in modern construction. And if you’re one of the many people involved in concrete-related ... Read More

It’s possible to argue that there’s not really any such thing as unprotected concrete. To start with, concrete is innately durable; and industry improvements on mix designs are actively focused on long-term structural life spans. Strictly speaking, concrete can be ... Read More

Every construction designer must know the old adage ‘If you can’t hide it, make a feature of it.’ Markham adding life to concrete This is classicly illustrated in the use of concrete in construction. In Australasia, there’s a tendency to ... Read More

It is generally recognised that moisture and moisture vapour carry contaminants which are detrimental to concrete. Yes, concrete contains and needs some moisture. No, we don’t want the contaminants which come with it. The challenge is how to allow the ... Read More

You’ve heard of AQURON 300? It’s that marvellous admixture version of the AQURON hydrogel treatment for concrete. Waterproofs! Strengthens! Improves concrete handling at construction stage! Enhances concrete durability for the life of the structure! Too good to be true? No! ... Read More

Concrete structures in marine tide or splash zones are especially vulnerable to ageing. Fluctuating marine moisture levels aggressively introduce contaminants such as chlorides and sulphates into the matrix of the concrete. These contaminants react within the concrete, accelerating the concrete ... Read More
