Concrete Technologies for Sustainable Buildings

Concrete Truck
This November 23, 2006 workshop discussed the need for sustainable concrete technologies in the emerging market for sustainable buildings.
This half-day breakfast workshop brought together experts from the concrete technologies sector, architecture and engineering professionals, and government officials to discuss the role of concrete technologies in the emerging market for sustainable buildings and communities. Please see attachment for the agenda of this past event.

EcoSmart Concrete

Cement Plant
The EcoSmart Concrete project aims to reduce the greenhouse gas (GHG) emissions associated with the production of Portland cement for use in concrete construction. The core technology consists of replacing the Portland cement in a concrete mixture with an optimum amount of supplementary cementing materials (SCM).
SCMs are industrial by-products or recycled materials with significant cost and environmental benefits. Tests and field applications have shown that EcoSmart concrete often outperforms conventional concrete in strength development and durability. It also offers significant environmental benefits, since each tonne of cement replaced by a supplementary cementing material reduces CO2 emissions by approximately one tonne. EcoSmart has facilitated a number of case studies demonstrating that a significant percentage of Portland cement can be replaced by SCMs without affecting cost, performance or constructability. The results and reports on these case studies can be obtained from the EcoSmart Concrete knowledgebase.

SOS Project approved by SDTC

SOS Network
Sustainable Development Technology Canada (SDTC) will provide funding for the SOS project. The project partners are currently coming together and the planning phase will commence June 2007.
EcoSmart and its partners will develop a system that will allow developers, architects, engineers, contractors and material suppliers to optimize the use of supplementary cementing materials (SCMs) by simulating the effects of varying these materials on construction projects. By determining optimal SCM levels, the system will reduce costs along with emissions of greenhouse gases and air contaminants by directly reducing the amount of Portland cement required for construction projects. The system will gather scientific and technical knowledge, experience and intellectual property on SCMs and make it available to industry through a continuously updated, computer-based system.

SOS project

SOS Network
The SCM Optimization System (SOS) is a decision-making system that enables the reduction of the quantity of Portland cement in concrete by determining the optimum level of replacement by supplementary cementing material (SCM).
There is an increasing awareness amongst the building industry that the use of high levels of supplementary cementing materials (SCMs) in concrete can bring substantial benefits in terms of performance, cost, and constructability in addition to dramatic improvements to sustainability and the greenhouse gas (GHG) signature of concrete construction. However, there is also concern about potential pitfalls, such as lower setting time, longer curing requirements, or the potential for SCMs to introduce harmful chemicals into the concrete. To address these concerns, a partnership led by EcoSmart is developing a ‘SCM Optimization System’ or SOS, a web-based decision-making system to provide online expert guidance concerning all aspects of, and the optimum use of, SCMS at all stages of construction – through concept, structural design, materials selection and proportioning, to construction management and implementation. The system will assemble and package the scientific and technical knowledge, experience and intellectual property of members of a partnership composed of concrete experts, university professors, researchers, structural and material engineers, architects, developers, contractors, cement manufacturers, SCM producers, and ready-mixed concrete suppliers.
