This type of recycled material has a higher strength rating than traditional raw materials, such as sand and gravel. The use of RCA can also help reduce costs by decreasing the need to mine new materials from our finite natural resources and eliminate landfill disposal fees.
In addition to reducing our dependence on finite resources, utilizing RCA helps cut carbon emissions. This is because less energy is required to mine and transport these materials. Moreover, RCA is usually sourced from nearby projects, allowing contractors to save on transportation costs and fuel consumption.
The increased use of RCA in concrete construction is helping to meet rising environmental standards and regulations. As a result, building codes are evolving to incorporate the latest innovations in concrete technology. Staying current with these changes is essential to ensuring that your project meets modern safety, performance, and sustainability standards.
Environmental considerations are driving design choices more than ever. From permeable precast driveways that allow rainwater to pass through, to large paver walkways that create a seamless aesthetic from sidewalk to patio, there are more options than ever for the eco-conscious contractor. By staying informed and embracing these advancements, the future of concrete construction looks bright. And by using these innovative technologies in the right way, it can also be more cost-efficient and durable than ever.
2. Carbon Capture and Utilization
Concrete is the most produced and consumed construction material worldwide. Its high carbon footprint makes it a target for innovation as the world moves towards sustainability. The good news is that there are a variety of new materials, mix designs and additives available that prioritize sustainability without sacrificing durability or strength.
Several North American companies are developing technologies that capture and utilize CO2 during concrete production to create carbonated concrete (CC). These include Blue Planet, CarbonCure, Cementicom, SUICOM, Paebbl, and Solidia Technologies. Their technologies have significant potential to address carbon emissions during the production of cement and concrete, while also aligning with scalability and market demands.
One method of carbon capture in concrete is through mineral carbonation. This is achieved by injecting previously captured CO2 into fresh concrete during mixing. The CO2 is then chemically reduced to form nano-sized calcium carbonate particles, which are then incorporated into the concrete mixture. This results in a carbonated concrete product with similar properties as regular concrete.
Another method is through substitution of traditional Portland cement with waste byproducts and recycled materials. Using these alternative cementitious materials can reduce the amount of CO2 released during manufacturing and increase the lifespan of the concrete structure.
Other sustainability advancements in concrete construction include the use of electric mixers that eliminate the need for gas engines and hoses. These machines allow for more precise mixing and control and minimize on-site waste by utilizing only the necessary amount of materials. The use of prefabricated structures also cuts down on construction time and allows for faster project completion. Finally, continued development on electrifying jobsite equipment mitigates trip hazards associated with cords and hoses and eliminates the need for maintenance, engine repair and gas storage.
3. 3D Printing
Every year at the World of Concrete, there is a palpable feeling that this age-old industry is advancing. On the exposition floor, you are surrounded by the latest mobile pumps and batching silos along with world-class technology companies with specialized products for concreting.
3D printing is a new concrete construction technique that uses a robotic process to layer-by-layer extrude concrete into precise and scalable building solutions. This method eliminates the need for formwork and allows engineers to design intricate structures with maximum geometric flexibility and artistic freedom.
The resulting structures can be printed on-site or off-site and prefabricated to reduce cost, labor, and material waste. This off-site construction method enables buildings, bridges, and infrastructure to be designed and built in a location different from the installation site. This is especially important for complex, high-rise projects where it is difficult to have the necessary number of skilled workers.
In addition, 3D concrete printing can also eliminate many of the limitations that designers have always had to work around in traditional construction. By optimizing concrete components for force flow or building physics, this technology can create non-standard construction solutions that would be impossible to build using conventional methods.
Lastly, self-healing concrete is another innovative concrete construction trend that utilizes smart materials to improve the efficiency and durability of concrete. Specialized bacteria incorporated into the concrete produce limestone that naturally seals cracks, decreasing maintenance costs and improving the structural integrity of the structure. This trend is particularly useful for high-rise structures and bridges where temperature fluctuations and environmental factors can cause structural damage. This smart concrete is also more durable and can withstand chemical attacks and freeze-thaw cycles, prolonging the lifespan of structures.
4. Artificial Intelligence
Artificial intelligence is a technology that gives software or machines the ability to think and act like humans. In concrete construction, AI is being used to improve quality, reduce waste and labor, increase efficiency, and even help with project planning.
For example, contractors can use AI software to compare poured concrete work to design and identify layout or sequencing errors, missing elements, uneven pours, or other problems in real time. This helps them to save on material costs, reduce labor, and make more accurate bids.
Another way that AI is being used in concrete construction is through vision-based algorithms such as Computer Vision (CV). CV allows a machine to interpret visual data, such as images and videos, and makes decisions based on it. In concrete construction, this has been used for analyzing and evaluating concrete structures, predicting their fresh45 and hardened46 properties, automated inspection47, and developing new materials48.
A growing trend in concrete construction is off-site fabrication, which is the designing, manufacturing, and assembly of components at a location that is different from the actual installation site. This method of construction is gaining traction in the industry due to its benefits, including cost reduction, increased safety, reduced environmental impact, and faster construction.
Off-site construction can also be used for precast concrete, which is a type of concrete that is built offsite, such as in a plant, then transported and installed at the installation site. This technology can be used in high-rise buildings and other critical infrastructure projects as it offers a higher strength, more durability, and lower maintenance costs compared to traditional concrete. It is a more sustainable option, as it requires less energy to produce and transport.
5. Drones
Once considered a novelty, drones are now an essential tool on jobsites across the construction industry. From creating digital twins of a job site to streamlining workflows and improving safety, UAVs are unlocking powerful new ways for construction professionals to manage projects in real time.
Drones can be used to survey worksite locations without exposing workers to hazards, such as heavy equipment, trenches or traffic moving around large job sites. Using advanced mapping software, these devices can quickly assemble images of a worksite into a three-dimensional map that provides rich data to support project needs, such as calculating stockpile inventories, monitoring environmental zones, checking road grades or monitoring compaction rates.
Moreover, these systems can be adapted for use on confined spaces like tunnels or passages that are unsafe to enter on foot. For example, a drone equipped with thermal imaging can patrol a jobsite at night to detect hot spots that may indicate fire or water leaks. This technology can help reduce costly repair and replacement expenses while making a jobsite safer for everyone involved.
Furthermore, drones can also be used to inspect concrete for quality control purposes. By utilizing 3D models that are regularly plugged into BIM software, these platforms can reveal discrepancies between design and reality. This enables concrete contractors to improve their production and management processes, while providing clients and partners with more accurate information that is easier for them to understand.
Drones can also improve productivity by helping a construction company track and record the progress of their work. With the ability to record high-definition video and take still shots, these technologies can be a powerful asset for any construction company.
