With climate change, it's becoming increasingly challenging to anticipate every type and frequency of disruptive threats. Therefore, concrete structures need to be designed with resiliency in mind in order to respond, absorb, and adapt to a variety of disruptive event in order to maintain functionality during and after the event. During this session, we will explore topics related to designing resilient concrete structures. We will discuss potential threats, and the critical factors of resilient infrastructure. We will look at current resilience-based performance standards and resources. This session contains valuable information for designers, manufacturers, educators and specifiers.
Learning Objectives:
(1) Describe the critical factors of resilient infrastructure and how they relate to concrete structures;
(2) Identify performance-based design and assessment frameworks that can help pinpoint critical damage and help predict the impact of disasters before, during, and after the event;
(3) Explain the development of resilience-based performance standards and current resources to help assess current infrastructure resilience and design sustainable systems that protect our communities;
(4) Describe specific resiliency-based design resources for seismic and flooding events.

Speaker: Thomas Sayre
Title: Earthcasting

Join us virtually for this Architects' Day Lunch and Learn. Speaker Thomas Sayre, one of the founding principles of Clearscapes, will discuss a novel technique called “earth casting” which he has employed all across North America as well as Asia and Europe to create large, permanent public sculptures. Earth casting involves digging large forms by hand and with heavy equipment in undisturbed earth and casting reinforced concrete directly into the earthen molds. The lecture will show multiple examples of this work and how the technique makes work which is uniquely “of the place” where the site is located.

Moderators: Ralf Leistikow, James D Lafikes

Shrinkage cracking is a major concern for certain projects and there are many different admixtures on the market that are intended to serve as a viable, cost-effective solutions. Implementation of certain technologies, however, is not always as effective. Issues due to concrete shrinkage can arise at early ages (during construction or within the first few days after placement) or in the following years during service due to materials, errors in batching, or construction procedures. Furthermore, the ways in which shrinkage is measured do not always account for concrete behavior/properties at early ages, making it difficult to quantify the effects of a given shrinkage reduction technology.
Presentations include a variety of topics from emerging technologies and test procedures, construction practices and field observations, and different perspectives of established technologies. Specific presentations will cover different approaches to internal curing, use of shrinkage reducing admixtures, micro reinforcing, shrinkage compensating admixtures, supplementary cementitious materials, high-performance concrete, a variation in free shrinkage testing, and field observations.
Learning Objectives:
(1) Identify mineral and chemical admixtures available to reduce shrinkage in concrete mixtures;
(2) Examine various applications of shrinkage reducing technologies in performance-based specifications;
(3) Describe early and later-age shrinkage behavior of different concrete mixtures;
(4) Discuss interactions between combinations of shrinkage reducing technologies.

Concrete is the world’s most widely used construction material. Yet, the production of portland cement, an essential constituent of concrete, leads to greenhouse gas emissions into the atmosphere. The production of 1 ton of portland cement clinker releases approximately one ton of CO2 and other greenhouse gases. Environmental considerations have been a major thrust for the sustainable development of the cement and concrete industries. A sustainable concrete structure is designed and built to have a positive environmental footprint during its entire life cycle. Concrete is increasingly being considered as a sustainable material owing to its low inherent energy requirements and little associated waste. Not only is it made from some of the most plentiful resources on Earth, it can also be made with numerous recycled materials and by-products and is itself entirely recyclable. Emerging breakthroughs in concrete technology have allowed producing ultra-high-performance concrete requiring less raw materials, along with structures that are much more durable to reduce maintenance, repair, and reconstruction.
Learning Objectives:
(1) Demonstrate how to evaluate concrete mixtures with various waste-by-product and recycled materials;
(2) Recognize many different types of testing that could be performed on new concrete mixtures produced with recycled materials;
(3) Explain the various methods to design and validate the concrete produced by new recycled materials;
(4) Specify emerging technologies in the concrete produced by recycled materials and its application in civil infrastructures.

Moderators: Ralf Leistikow, James D Lafikes

This session will review the use of current technologies available to reduce shrinkage in concrete, including mineral and chemical admixtures and various alternative approaches in concrete mixture designs. Cracking due to restrained shrinkage is one of the primary contributors to cracking, particularly in concrete flatwork, which potentially reduces the service life and increases the required long-term maintenance of concrete structures. Mitigation of different shrinkage mechanisms in concrete can be accomplished through combinations of shrinkage reduction technologies. A review of how these technologies affect concrete properties and shrinkage behavior will be presented. Completed research and full-scale field observations will examine the effectiveness of an array of shrinkage reduction technologies.
Learning Objectives:
(1) Examine various test methods used to evaluate shrinkage;
(2) Discuss how concrete mixture proportions are designed to mitigate shrinkage;
(3) Identify how shrinkage-reducing technologies are implemented in full-scale projects;
(4) Examine similarities and shortcomings of different shrinkage-reducing technologies in laboratory test results and performance of full-scale projects.
