Does the Non-Shrink Grout ‘Unicorn’ Really Exist? – Part 2
Last week we discussed the different types of shrinkage and the dimensional stability of grout products. This week we will examine timing, testing and shrinkage compensation of grout. In the most part, engineers and applicators will observe shrinkage at a specific point in time. Test data will often refer to ‘28-day shrinkage’ which is the […]
Does the Non-Shrink Grout ‘Unicorn’ Really Exist? – Part 1
Posted in Cements, Grouts & Mortars, Civil Engineering Tips
Just like the elusive unicorn, there’s a willingness to believe that non-shrink grouts really do exist. This imaginary grout not only lives on in the eyes of some engineers and end-users, but is repeatedly peddled by some of the leading suppliers of high-performance pre-packaged grout products. To determine once and for all if this ‘unicorn’ […]
The 5 Main Types of Concrete Failure
In the world of concrete failure, the cause of the problem is not often visible, rather it is just a symptom of the real cause. Before any external faults show, stresses build up, internal chemical reactions may take place and unknown costs are already needed to repair the concealed failure. By the time it is […]
The Three Golden Rules for Fast Set Concrete
