World of Concrete Trivia
Question #1
Where is the first reinforced concrete building built in
Chile?

Question #1
Where is the first reinforced
concrete building built in Chile?
Edificio Ariztía is a building located at 52
Nueva York Street in downtown
Santiago, Chile, on a wedge-shaped city
block. It was completed in 1921 and is
considered the first "skyscraper" in
Santiago.

Question #2
Who invented the world’s first ready-mixed concrete truck?

Question #2
Stephen Stepanian invented
a self-discharging motorized
transit mixer that was the
predecessor of the concrete
mixer truck and applied for a
patent in 1916. However, the
patent was rejected in April
1917 by the patent office
because it was believed that
a truck could not support
the weight of a concrete
mixer on top of it

Self Healing Concrete

Rapid Drying Concrete is the first
ready-mixed concrete solution for
preventing moisture-related floor
covering failures, an industry-
wide problem that costs millions
of dollars annually in damage,
downtime, repair and
replacement. For mission-critical
facility construction, rapid-drying
concrete accelerates construction
projects and eliminating the need
for add-on moisture mitigation
products.

OysterBreak is a patented
technology uses the oyster's
inherent nature of clustering to
enhance a strategic coastal
protection structure for coastal and
estuary shorelines.

Marine Concrete

OysterBreak is designed to
protect shoreline projects that
calls for any combination of wave
attenuation, and shoreline
erosion mitigation. OysterBreak
units are designed to serve dual
functions by creating a reef
structure for habitat and robust
structure for shoreline protection.
Marine Concrete www.wayfarertech.com

Marine Concrete www.econcretetech.com
ECOncrete®'s unique biological traits encourage biogenic buildup. They
also provide substantial structural and economic advantages in terms
of increased stability and longevity, as well as a reduction in
maintenance costs.
The Company's products are adapted to specific environments with
their typical fauna and flora. ECOncrete® maintains ongoing research
and development activities for expanding the company's product
range, addressing needs of new geographical locations, and optimizing
product structural and biological performance.
ECOncrete®'s experts closely cooperate with landscape architects,
engineers and policy makers in the design of new coastal and marine
infrastructure as well as in retrofitting existing structures for optimal
biological productivity and ecological efficiency.

Ecological Pile Encapsulation
ECOncrete®'s ecological pile encapsulation
substitutes standard concrete pile
encapsulation. It is applied to repair timber
piles, used in piers and jetties, since timber
piles deteriorate after being exposed for
long periods of time to marine burrowers,
such as worms and mussels. In addition to
the necessary constructive support and
protection, ecological pile encapsulation
creates a new and productive habitat for
marine plants and animals.

These are a new range of modular
esthetic sea wall elements, which
functionally integrate into coastal
infrastructure.
The surface properties are tailored to
induce growth of specific species of
conservational value. Slight design
changes can increase complexity,
providing additional shading and
refuge from sea waves with no
decrease in the structural and
functional properties of the sea wall.

Bio-active Walls
Bio-active wall elements are designed to induce
rapid plant wall coverage of inland buildings.
Green plant coverage significantly improves
urban landscape, provides cleaner and healthier
air, and reduces the ecological footprint of urban
development.
The physical and chemical properties of the wall
substrates strongly influence its capability to
support and enhance growth. ECOncrete®'s bio-
active wall induces natural growth of wall
clinging plants, endolithic algae, lichens and
mosses. Its high complexity and porosity create
moist niches that support flora, without the
need for complex soil systems.

A concrete matrix embedded with a microencapsulated
sodium silicate healing agent. The result is self-healing “smart
building materials”.
The material comes into action when cracks form in the
concrete; the ruptured capsules release the embedded agent
into the adjacent area. Sodium silicate reacts with the calcium
hydroxide, already present in the concrete, forming a calcium-
silica-hydrate gel. That gel heals the cracks and blocks the
concrete’s pores. The gel hardens in about one week.
Research has shown that self healing concrete can recover
26% of its original strength, while conventional concrete only
recovers 10%. It is believed that the strength can be boosted
by increasing the quantity of the healing agent.

In-Route Slump Adjustment
Drum Cleanout Equipment

Adding liquefied CO2 to the batch is easily incorporated into ready-mixed concrete and
concrete masonry operations.
CO2 Concrete
carboncure.com

Using a special dispensing unit, liquefied CO2 is metered in to the freshly batched concrete
mix.
CO2 Concrete carboncure.com

When liquefied CO2 is injected
into wet concrete it chemically
reacts with calcium ions released
from cement to form solid, nano-
sized calcium carbonate particles
that become permanently bound
within the concrete. The carbon
dioxide binds as solid and stable
carbonate reaction products in
the cement matrix and provides a
positive impact on the concrete
properties.
CO2 Concrete

The system allowed the
producer to reduce the
cement binder. Test
comparisons were made to
7,14, & 28 day compressive
strengths for non-air
entrained mixes.

• non-entry cleaning system.
• The agitator drum remains stationary so drivers don’t have to
climb to clean the exit area.
• Drivers work from an enclosed protective booth.
• The unit has a small footprint of 2 m x 1.2 m (6.7ft ft x 3.9 ft) with
the boom length of between 8 meters and 10 meters for different
size mixer trucks.
• Using recycled or fresh water.

Bridge Slide Construction

Post Tensioned Bridge Slabs
The new bridge was designed
with a span of 45-feet. Due to
this span length, not being
conducive to standard precast
slabs, Oldcastle Precast
engineers partnered with VSL
Structural Technologies to
create a custom precast
solution.

Oldcastle Precast and VSL decided to
install post tension cables in the slab
during the precasting process.

They manufactured the custom
post tensioned bridge slabs,
measuring 5-4’-wide by 2’-thick
by 45’-long, Oldcastle Precast
Idaho Falls shipped them to the
bridge site.

The Next Generation Concrete Surface
(NGCS) is the first new concrete texture
introduced in the past 20 to 30 years. It
was conceived as a manufactured texture
whose properties are consistent and
predictable and represents the quietest
nonporous concrete texture developed
to date. At the time of construction the
NGCS is typically 99 dBA in noise level
and has a range up to 101 dBA over time.
Although the NGCS has only been in
service 3 years, it is under evaluation at
13 locations in 9 states with more to
come.
