Nothing -- and something -- give concrete strength, toughness

Rice University scientists show how voids, particles sap energy from cracks

10-Aug-2016

What does one need to strengthen or toughen concrete? A lot of nothing. Or something. The "nothing" is in the form of microscopic voids and the "something" consists of particular particles embedded in the most common construction material on Earth. Rice University materials scientist Rouzbeh ...

Finding a new formula for concrete

Looking to bones and shells as blueprints for stronger, more durable concrete.

27-May-2016

Researchers at MIT are seeking to redesign concrete — the most widely used human-made material in the world — by following nature’s blueprints. The team contrasts cement paste — concrete’s binding ingredient — with the structure and properties of natural materials such as bones, shells, and ...

Riddle of cement’s structure is finally solved

Findings may guide development of formulas to make the material more durable, less CO2-intensive

10-Feb-2016

Concrete is the world’s most widely used construction material, so abundant that its production is one of the leading sources of greenhouse gas emissions. Yet answers to some fundamental questions about the microscopic structure and behavior of this ubiquitous material have remained elusive. ...

Structure of 'concrete disease' solved

09-Nov-2015

Researchers from the Paul Scherrer Institute (PSI) teamed up with colleagues from the Swiss Materials Science Lab Empa to study a degenerative sign of ageing in concrete: the so-called alkali-aggregate reaction (AAR). In the course of AAR, a material forms that takes up more space than the ...
