Historical Overview on How Concrete has Changed the World

World of Concrete Trivia Question #1

Where is the first reinforced concrete building built in Chile?


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.


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


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.

Innovations in MaterialsThese 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.

Innovations in Concrete Production


Topics CO2 Concrete

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 Concretecarboncure.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.



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.

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.

Innovations in Concrete Roadbuilding


Topics Post Tensioned Bridge Slabs

Next Generation Concrete Surface

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.
