CTI UHPC is a class of concrete that is exceptionally strong and durable. Originally developed by the U.S. Army Corps of Engineers, it combines form and function with strength and resiliency.
CTI Concentrate is our standard material formation. It is a highly versatile mix that can be used as a direct replacement for standard concrete. It is compatible with all industry-standard production techniques, ranging from large-scale precast facilities down to small, cast-in-place applications. This includes (but is not limited to):
Pre- and post-tensioned structure component construction
Field-cast structural connections
Wear surface overlays
Injection and extrusion techniques
Blast and corrosion resistance
Constituents, Packaging, and Yield
Our pre-mix contains proprietary pre-blended constituents. Complete pre-mix (with sand and cement) is available upon request. Our liquid admixture acts as a corrosion inhibitor and a high-range water reducer, resulting in an impermeable UHPC mix. Our steel fibres measure 0.008 inches (0.20 mm) in diameter and are 0.5 inches (13 mm) long. Not included in pre-mix.
Our UHPC is highly versatile and can be batched in a variety of solutions ranging from high-yield, and industrial applications down to single-yard solutions. However, high-shear mixers are recommended to properly batch CTI Concentrate. UHPC is available to consult prior to batching for the evaluation of equipment.
UHPC can be poured using a variety of industry-standard means and methods. UHPC has successfully been poured into ready-mix trucks, Tuckerbilt dispensers, skid-steer auger buckets, and all manner of conventional wheelbarrows, buckets, and buggies.
Long-Term Cost Savings
UHPC is the ultimate material for low-impact design, dramatically reducing life cycle costs. When compared to steel, UHPC is more cost-effective and durable, making it the superior choice. Choosing UHPC for your project results in the following savings:
Construction can be completed faster with prefabricated UHPC elements
Less material is required for construction, reducing transportation and machinery costs
Sizing and complexity of footing and support requirements are reduced
Extended longevity virtually eliminates maintenance costs and supports environmental conservation
When concrete cracks, water and air get in, which speeds up the degradation of the concrete. What if concrete could stop the degradation process and heal itself?
Innovations are taking shape with concrete that contains bacteria that produce limestone when it comes into contact with water and air, repairing the crack. This self-healing concrete is being made for new mixtures, as well as a repair mortar for existing structures. Other self-healing techniques being researched include hydrogels that swell when water gets in and capsules of polymers that break when cracks form. Once broken, the polymers inside the capsule seal the crack.
Of course, these more advanced types of concrete will cost more money initially—but if they can extend the life of concrete structures, they may be less costly in the long run.
Visual interest and design are united in graphic concrete. This technology is used on precast concrete to create a patterned surface.
Images can be applied as well. The concrete itself lasts just as long as the plain version. The addition of this aesthetic element to concrete makes it a more favourable choice on projects where plain concrete would seem too plain or boring.
Concrete 3D printing provides many benefits.
Unique concrete designs can be crafted that may have formerly been impossible. Affordable homes can be made for lower-income families or those recovering from a disaster. Production time on projects can be drastically reduced.
Of course, this is still a newer technology, and we don’t expect to see its use in large-scale projects, as the size of the printer limits the size of the item that can be created. However, cost savings, the ability to produce complex structures, and urbanization will all drive the adoption of 3D concrete printing.
Cement that can absorb and radiate light has been developed by José Carlos Rubio Ávalos in Mexico. The cement can be created at room temperature, which is a huge energy saver.
It can light up roadways, bridges, bike paths, and more—all without electricity. So how does it work?
The cement absorbs solar energy during the day and can then emit light for about 12 hours. In order for this to be possible, the crystallization in the cement was removed so light could pass inside. It was replaced with a gel consistency.
The product can currently emit either green or blue light, and the brightness can be adjusted during production.
Slightly different from light-generating cement, translucent cement allows light to transmit through it. This quality comes from optical fibre strands within the concrete.
Just how translucent is it? You would be able to clearly see the outline of something on the other side of the cement block or wall, yet it still offers the same strength as regular concrete.
It is being used in structures such as partition walls and stairs to add a design element to what would have been an otherwise plain concrete structure.
