"Treat the Earth well.

Why Does It Matter? Earth Environment protection, global warming and climate change are becoming an increasing priority for everybody – nations, companies and individuals. Reducing carbon footprints is the topmost concern. Carbon footprint is a measure of the impact of human activities leave on the environment in terms of the amount of green house gases produced, measured in units of carbon dioxide’. It is meant to be useful for individuals and organizations to conceptualize their personal or organizational impact in contributing to global warming. Reduce your carbon footprint. Whether in coal, oil or gas, carbon is the essential ingredient of all fossil fuels. When these fuels are burned to provide energy, carbon dioxide (CO2), a “greenhouse gas”, is released to the Earth’s atmosphere. As we’ve become more dependent on carbon-based fuels, we’ve seen a rapid increase in the atmospheric concentration of CO2; from around 280 parts per million (ppm) before the industrial revolution, to 370 ppm today. If current trends of fossil fuel use continue the concentration of CO2 is likely to exceed 700 ppm by the end of this century... leading to faster global warming and more ecological disturbances around the world.
Concrete and CO2 Every 1 ton of cement produced leads to about 0.9 tons of CO2 emissions and a typical cubic meter of concrete contains about 15% by weight of cement. Numerous articles have been written about reduction of CO2 emissions from concrete primarily through the use of lower amounts of cement and higher amounts of supplementary cementitious material (SCM) such as fly ash and slag and use of high range water reducing admixtures for reduction of water usage. Since a cubic meter of concrete weighs about 2.4 tons, CO2 emissions from 1 ton of concrete varies between 0.10 to 0.16 tons. Approximately 95% of all CO2 emissions from a cubic meter of concrete are from cement manufacturing; therefore, it is no wonder that much attention is paid to using greater amounts of SCM and high performance admixtures.
What Is Concrete? Concrete is one of the most versatile and widely used building materials in the world. It plays a vital role in many aspects of everyday life – from the buildings we work and live in, to the roads, bridges and railways that transport us. It is a key element in the social and economic well being of us all. Throughout its lifecycle, concrete can deliver real sustainability benefits, but it also has some negative impacts. Sustainability is a key issue for the concrete industry in our region. The use of concrete can offer significant sustainability benefits in the life cycle of buildings and structures. Its thermal mass is highly efficient in reducing the energy needed to heat and cool buildings, and it also allows a high level of air tightness. Concrete is highly durable and so needs minimal maintenance and can thus reduce whole life costs. Furthermore, the long life of the material means that concrete structures are appropriate for change of use. Concrete’s mass and damping qualities allow good acoustic performance and minimize movement, reducing floor vibration. This is particularly advantageous for high density accommodation. Concrete is non-combustible and has a slow rate of heat transfer which makes it a highly effective barrier to the spread of fire. The nature of the material also ensures that it is resilient to flood damage. We are tackling the industry’s own performance heads on, enhancing positive attributes and managing and reducing other impacts through technical innovation and concrete design. The industry is committed to behaving in a responsible way to improve sustainability performance and to deliver sustainable construction solutions.
Can We Make Concrete GREENER? Enviromental Management Concrete mixture design The type and amount of cement has a major influence on the environmental properties of a concrete. The energy consumption of cement production makes up more than 90 % of the total energy consumption of all constituent materials and approximately 1/3 of the total life cycle energy consumption. By selecting a cement type with reduced environmental impacts and by minimizing the amount of cement, the concrete’s environmental properties are drastically changed. This must, however, be done whilst still taking account of the technical requirements of the concrete for the type and amount of cement. One method of minimizing the cement content in a concrete mix is by using packing calculations to determine the optimum composition of the aggregate. A high level of aggregate packing reduces the cavities between the aggregates, and thereby the need for cement paste. This results in better concrete properties and a better environmental profile, due to a smaller amount of cement. When having experimentally determined the packing, the density, and the grain size distribution of each aggregate material, it is possible to calculate the packing of any combination of aggregates using computer program. Another way of minimizing the cement content in a concrete is to substitute parts of the cement with other Pozzolanic materials. In our region, it is common to produce concrete with fly ash, GGBFS and/or micro silica fume. These materials are residual products (by - products from production of electricity, iron and steel making and production of silicon respectively) and both have a Pozzolanic effect. Thus, a material with large environmental impact, i.e. the cement, is substituted with materials with reduced environmental impacts. In order to reduce the consumption of raw materials and to minimize the waste generated from demolished concrete structures, surplus, and production errors, crushed concrete can be reused as aggregate. It is expected that the use of recycled aggregate in concrete, for passive environmental class will be allowed. Also recycled water, initially used for washing out the aggregates from surplus concrete and cleaning the production equipment, is allowed in the new concrete standard.
Concrete & Sustainability Cement and concrete production It is also possible to reduce a concrete’s environmental impact by reducing the environmental impacts in cement and concrete production. The cement manufacturer has many activities concerned with the reduction of environmental impacts. With regards to concrete production, experience with reductions of primarily water consumption, energy consumption and waste production is available. Even though the contribution of concrete production to a concrete’s environmental profile is not so big, it does give a contribution, and should be taken seriously - environmentally and economically - by every concrete producer. Steps for a “GREENER CONCRETE“ • Increase the use of conventional residual products, i.e. fly ash, GGBFS, silica and other Pozzolanic materials • Use residual products from the concrete industry, i.e. stone dust (from crushing of aggregate) and concrete slurry (from washing of mixers and other equipment). • Use residual products from other industries not traditionally used in concrete, i.e. fly ash from bio fuels and sewage sludge incineration ash (from sewage treatment plants). • Use new types of cement with reduced environmental impact. • Use recycled aggregate • Use renewable energy, including biomass, solar, wind, geothermal and hydroelectric power to reduce plant CO2 emissions • Use recycled water initially used for washing out the aggregates from surplus concrete and cleaning the production equipment • Use high range water reducing admixture

One of the examples of a green concrete is pervious concrete. Known for its ability in storm water management, it’s one of the major breakthroughs in green concrete design. Pervious concrete is a mix of coarse aggregate, cement, water, and little to no sand. Also known as “no-fines” or pervious concrete, this mixture creates an open-cell structure, allowing rainwater to filter through to underlying soil. By modeling natural ground cover, pervious concrete is an excellent choice for storm water management.
EPSILONE... For A Greener Concrete Sodamco-Weber has expanded its ACP range to include EPSILONE a new generation of high range water reducing dispersants admixture based on synthetic polymer technology producing extended workability retention at controlled dosages with no strength loss, to serve the following industries: • Ready mixed high performance sustainable concrete • Precast manufacturer (Hollow core, precast panels, in-situ.etc…) • Concrete manufactured products (blocks, kerbs, pavers, GRC, etc..) • Shotcrete industry
Sodamco-Weber's products, particularly EPSILONE, answer the demand for green in a variety of ways: • Optimized Portland cement use - Rather than only using portland cement, which requires an especially energy-intensive manufacturing process, Epsilone is highly effective with the use of supplementary cementitious materials (SCMs) as portland cement replacements. • Reduction of water use - Water is becoming an increasingly precious resource and reductions in water use have become a key environmental indicator. EPSILONE high range water reducing types allow significant reductions to be made in the water demand of concrete without affecting consistence (workability). At the same time, environmental performance and/or durability and strength will generally be improved. • Reduced energy - EPSILONE contributes to the reduction of energy use by providing more fluidity in the fresh concrete resulting in reduced batching energy, pumping energy & transportation energy. Epsilone HP series can also provide self consolidated
properties for lower placing energy (vibration) and provide higher workability that assist in reduction in construction times leading to reduced labor requirements. • Enhanced durability & Quality – EPSILONE contributes to the overall durability and life expectancy of a building by reducing corrosion, service life repair and other detrimental effects. • Carbon Footprint - The main sustainability benefit of admixture use comes from optimization of the mix constituents in order to reduce both the embodied carbon dioxide and the water content of the concrete without any loss in other properties. • Natural Resources - Epsilone enhances concrete performance even with use of recycled materials and reduces the use of virgin materials, which in turn reduces environmental burdens.
