How to build the most durable slabs
on Earth.
The answer is simple. Stop cracks before
they happen. In fact, you can prevent all kinds of costly problems with Type K Expansive
Cement from Blue Circle.
You know what happens with ordinary portland cement. It loses moisture,
so it loses volume. It "shrinks." But Type K Cement turns ordinary concrete into
Type K Shrinkage Compensating Concrete. It expands to compensate for the shrinkage. So
when the concrete dries out after curing, it returns to the same volume that was
originally placed. And as a result at all the advantages you get!
You can do away with trouble-making control joints.
With Type K Cement, you are free to pour concrete in much larger areas
without control joints. 18,000 sq. ft. of joint-free placements are common, and areas as
large as 30,000 sq. ft. have been placed successfully. Dry shrinkage cracks are
dramatically minimized. Once you eliminate joints, you automatically prevent all kinds of
costly maintenance problems.
No more slab curling.
You can virtually forget about curling or warping. Simply put,
this is because Type K expands faster on top and this causes reverse curling. The weight
of the concrete keeps the slab flat. With proper reinforcement and care in placing, your
floors will be beautifully smooth.
Increased sulfate and abrasion resistance.
You will get a harder, denser concrete surface with Type K.
According to studies, Type K Shrinkage Compensating Concrete is up to 40% higher in
resistance to abrasions. And because it is adequately sulfated, it also has a higher
resistance to damaging chemical attacks. Voids are largely eliminated because there is
little or no bleed water.
Greatly reduced maintenance costs. Much longer
life.
While Type K Shrinkage Compensating Concrete may cost a little
more than ordinary concrete in the beginning, it will pay for itself over and over again
as time goes on. Structures made with Type K concrete will still be in service long after
ordinary concrete structures have been replaced. And during its long lifetime, the Type K
structure will save on all types of maintenance costs. You can't lose.
