Low-Carbon Concrete: Contractor Challenges and Opportunities

DOWNLOAD PRESENTATION

Sarah Rege, Senior Sustainability Director at Webcor and Eric Peterson, Director at Webcor Concrete

New requirements and policies for low-carbon concrete are sometimes implemented without thorough consideration of potential coordination issues with other policies and practices that haven’t yet been modified for consistency. Significant changes in cementitious materials and methods of evaluation of these materials are making their way into marketplaces and material standards. Concrete contractors (and designers) must pay closer attention to these changes than they have in the past. For a concrete contractor, it is a time to participate in discussions with producers, governments, code-writing bodies, technical associations, materials suppliers, and contractors associations. Doing so will help ensure that the coordination and information transfer that must occur without disrupting our industry and its economics can be facilitated. The challenge is keeping communication channels open so everyone understands what needs to happen to appropriately facilitate and implement these industry changes. Information awareness and communication are the underlying messages of this presentation.

Less Clinker in Cement, Less Paste in Concrete: A Two‐fold Strategy Towards Decarbonization

DOWNLOAD PRESENTATION

Franco Zunino, Physical Chemistry of Building Materials, Institute for Building Materials, ETH Zürich, Switzerland

Concrete is by a substantial margin the most widely used construction material. Projections indicate that the demand for concrete it will continue to increase to sustain the development of emerging economies. This paper presents a new perspective of low‐carbon concrete by refocusing on the actual final product, highlighting the tremendous CO2 saving opportunities of reducing the total paste volume of concrete while simultaneously using high performance, low‐clinker cements in the so‐called two‐fold strategy (low clinker content, low paste volume concrete formulations). Different aspects of low paste volume concrete formulations are discussed based on a combination of published and new concrete performance data, showing the potential for CO2 savings of the strategy and the technical opportunities to retain the robustness and reliability that make concrete such a versatile and widely used material. Chemical admixtures play a crucial role in reaching those objectives, as they enable to reduce the cement content while retaining the needed workability (slump and slump retention) for each application. The key issues relating to using those admixtures in low carbon concrete are highlighted.

Improving the Efficiency of Concrete Structural Design through Alternative Reinforcement: A Serviceability Based Design Approach

DOWNLOAD PRESENTATION

 

Dr. Barzin Mobasher, PhD. PE. FACI, FRILEM, Professor, School of Sustainable Engineering and Built Environment, Arizona State University, Tempe, AZ

 

One of the most inefficient and unsustainable guidelines for structural design of concrete is to ignore the potential for tensile load-carrying capacity of concrete. When dealing with concrete brittleness, our traditional approach is to use more reinforcing steel to carry tensile loads leading to larger volumes of concrete and steel, resulting in reduced durability and increased carbon footprint. This presentation will focus on reducing the reliance on conventional reinforcing by introducing fiber reinforcing materials at the microscale, allowing the integration of tensile properties in structural design to improve durability and efficiency. New test methods will be presented to validate the potential benefits by identifying the controlling mechanisms of various fibers and textiles. Applications to address improved ductility-durability measures including correlation of ductility, crack width, stiffness degradation, and fatigue response with service loads will be presented. Several case studies will showcase the significant cost savings, and enhanced performance of these methods.

Portland limestone cement (PLC) and new blended cements using pozzolanic materials (fly ash, natural pozzolan and calcined clay (CC)), as well as ternary binders based on several supplementary cementitious materials (SCMs), are promising alternatives to conventional Portland cement. These options hold great potential for reducing the carbon footprint of concrete. Chryso has developed a new generation of cement and concrete strength enhancers that improve the viability and performance of PLC and blended cements in North America. These additives help overcome some of the challenges associated with these alternative cements, such as increased water demand, reduced strengths, and pack set issues.

Biochar-Cement Concrete: The Path to Carbon Neutrality and Strength Parity

Lori Tunstall, Assistant Professor, Colorado School of Mines

In the last decade, biochar has emerged as a promising partial cement replacement to significantly reduce the carbon footprint associated with concrete. This is because biochar is a carbon negative material, sequestering more than twice its weight in CO2. The more cement that can be replaced with biochar, the lower embodied carbon the concrete will have; however, most researchers have found that replacing the cement with more than 5 wt% of biochar results in decreased strength, which limits the environmental benefit. In contrast, through a study of 22 distinct biochars, we have found that up to 44 wt% of the cement can be replaced with biochar, resulting in comparable or improved mortar strength and the potential to completely offset the carbon footprint of the cement. Using advanced data processing techniques, we identify three key biochar characteristics that control strength development of biochar-cement mortars: available water sorption capacity, oxygen-to-carbon ratio, and soluble silicon.

Proactive CO2 reduction with TiO2-based surface treatments: Overview of methods, initial results & future perspectives in pavement applications

DOWNLOAD PRESENTATION (coming soon)

Mirian Velay-Lizancos, Assistant Professor of Civil Engineering, Purdue University

It is known that TiO2 is a photocatalyst that can be used in construction materials applications as it provides them with photocatalytic properties, such as NOx removal. In addition to this property, our recent studies have shown the potential to increase the CO2 capture abilities of construction materials by adding nano-TiO2 into cementitious materials as part of the mix. These studies showed that these additions promoted the CO2 uptake to a certain level, depending on the samples' w/c and age, through carbonation acceleration, reducing the material's environmental footprint. However, the cost of nano-TiO2 and the potential increase in risk of corrosion if used in steel-reinforced concrete may reduce its applicability in the short term. Thus, our new study assesses the potential use of a TiO2-based surface treatment and its effect on CO2 concentrations and carbonation. These treatments present a cost-effective way to deliver TiO2 to pavements. However, their effect on the pavements differs from the effects of adding TiO2 into the mix since a surface treatment applied after the pavement has hardened will not modify the hydration process. Thus, we developed a new technique to assess the potential proactive effects of the surface treatment over the pavement's service life. Results showed that samples with the surface treatment reduced the concentration of CO2 to a greater extent than untreated samples. Furthermore, results also showed that, in this case, the reduction of CO2 concentration is not related to an increase in carbonation depth. Treated samples also showed self-cleaning ability. Thus, these treatments present a cost-effective way to deliver TiO2 to pavements, providing them with a long-lasting CO2 reduction ability.
