New advancements in concrete and cement-based products are completely changing the design and construction worlds.
With the explosive growth in high-rise residential construction, the Load-Bearing Wall (LBW)
system is gaining recognition. The walls and slab are poured
simultaneously when using the innovative tunnelform construction method.
Since the forms are stripped in 24 hours, the daily cycle meets the
demand of fast-track construction for repetitive cell layouts,
synonymous with many hotel and condominium projects.
The Tilt-Up industry
is reaching new heights with the record lift nearing 100 feet.
Production is streamlined with embedded facers cast integrally with wall
panel to greatly reduce labor requirements with conventional brick and
mortar veneer.
Lightweight Masonry takes
the form of Aerated Autoclaved Concrete block (AAC). With sufficient
structural capacity to be used as low-rise bearing walls, AAC block
greatly reduces masonry partition wall weights for elevated slab
construction. Masonry construction is also making a new visual statement
with the use of colored grouts. The pigmentation of white cement is
helping architects provide a new unity or contrast look to the typical
brick and mortar façade.
Self Consolidating Concrete (SCC) eliminates the need for mechanical consolidation and yields a smooth surface finish without mix segregation. More.
Ultralite panels are being manufactured with Carbon Cast,
a grid of carbon fiber reinforcing. The resulting weight reduction
generates savings in shipping, erection, and substructure costs.
The new P.O.S.T. (Prestressed Open Space Truss) provides
a solution for long-spans, while maintaining the shallow floor depth of
a flat plate system. This system works well for hotel and condominium
applications, especially with coveted parking spaces in the lower
levels.
Hybrid
construction marries the benefits of PC and CIP for a desired result,
such as seismic performance, cost savings, or schedule implications.
Insulated Concrete Form (ICF) walls are
gaining popularity in the residential nad commercial markets. In
addition to rapid construction, energy savings and increased durability,
owners also gain a healthier and quieter environment. Most recently,
blast-test experiments showed exceptional results for resistance to
catastrophic loadings, including fire, wind, and tornados.
Fabrication and corrosion are the crux of most rebar issues. “Reinforcement Carpet” gives
a unique solution to reduce shipping and erection costs. With little
waste, this innovative tool may greatly change the speed and precision
of concrete mat construction. Galvanized and stainless clad rebar offer
less expensive, but corrosion-resistant alternatives to stainless steel
rebar. The latest technology of MMFX microcomposite steel gives a high-strength, corrosion-resistant product with a cost-effective price.
The first-ever national partnership of precast companies, AltusGroup, was founded to develop, manufacture and market precast innovations such as the breakthrough CarbonCast™. With more than 25 structural and architectural locations in the United States, AltusGroup companies have an unparalleled national network of manufacturing plants, technical staff and sales personnel to ensure architects, engineers and contractors that they will receive the help they need — and the quality and performance they expect.
Decorative Concrete
White cement is the key ingredient in decorative concrete. New coloring agents and admixtures help create beautiful structures and landscapes. Imagine the possibilities! Click here for more on decorative concrete.Formwork

New Technologies
Many new technologies are changing the way we build and what we build with concrete.- Adding optical fibers to a concrete mix generates translucent concrete. This “see-through” development is changing the perception of concrete’s opaque mass.
- Reactive powder concrete is extremely workable, durable and yields ultra-high strengths without using coarse aggregates. Reaching compressive strengths of 30,000 pounds per square inch (psi), this new-age concrete also has tensile strength with the inclusion of steel and synthetic fibers. More.
Precast Industry
SCC and computerized precision color are revolutionizing the precast industry.Reinforcement
Post-Tensioning has new construction and retrofit applications. An intumescent material creates fire-resistant PT strands for bridge deck and parking garages. The “Spider” method retrofits buildings for earthquake protection, while External Post-Tensioning (EPT) helps solve strength and serviceability problems.Fabrication and corrosion are the crux of most rebar issues. “Reinforcement Carpet” gives
