Heated Clays for Sustainable Construction Materials
Heated Clays for Sustainable Construction Materials
During his PhD studies, Nishant Garg has explored the potential of heated clays in terms of partially replacing the cement in concrete. The ordinary Portland cement is responsible for 5-8 % of the anthropogenic CO2 emissions. Due to the significant growth in cement production, reducing its carbon footprint by substituting it with supplementary cementitious materials is a global objective.
Nishant Garg has evaluated some of the widely abundant clay minerals, like montmorillonite and illite. Specifically, he has analysed their structure and reactivity as a function of the heating temperature by solid-state NMR. His research findings contribute to a better understanding of factors governing the reactivity and performance of these heated clays.
The PhD degree has been completed at the Interdisciplinary Nanoscience Centre (iNANO), Science and Technology, Aarhus University.

Construction materials in Panama
Construction materials in Panama
Between January and May an increase of 5.7% was registered in the building permits, which forecasts, according to industry representatives, good perspectives for the coming months. On the other hand, production of ready-mixed concrete, for example, declined by 22% and gray cement 2.6%, indicating that overall construction fell in the first five months of the year.
Figures from the General Comptroller of the Republic indicate that "... from January to May 2015 permits for residential construction were requested worth $407 million and non-residential projects, for $448.5 million. In the first five months of the year, most of the demand for building permits was in the district of Panama, when they totaled $591.4 million and an expansion of 6.8% was achieved. In the district of Arraijan the value was $81 million and grew bby 27.7%, while in Colom the total was $58.2 million and increased 7.7%. "
Laestrella.com.pa reports that "... For construction materials, the results show a decline in production. Concrete production fell by 22.2% in the first five months of the year.One explanation for this sharp decline is in the completion of the expansion project of the Panama Canal. "

Building & Construction Products
Building & Construction Products
At DuPont, we’re focused on dynamic science that generates real-world solutions for the Building & Construction Industries.
That’s why DuPont is at the forefront of building science, with brands you depend on, like Tyvek®, SentryGlas®, Corian® solid surfaces, Zodiaq® quartz surfaces and KEVLAR®. DuPont is showing up for work at residential and commercial job sites around the globe. We're meeting the challenges of discovering and developing the innovative solutions you need in a changing world.
Sustainable Design without Compromising Performance:
Now, you can create stunning residential and commercial spaces with a smaller environmental footprint.
More and more homeowners, designers, and architects are searching for sustainable design products. At DuPont, we’re innovating, so you can do that without sacrificing durability or beauty. The DuPont™ Corian® Terra Collection is made with a minimum of 6% pre-consumer-recycled content — and some colors contain significantly more. The DuPont™ Zodiaq® Terra Collection is the same sophisticated quartz surface as ever, but now its composition includes a percentage of post-consumer- recycled content. (Post-consumer content percentages vary by color.) Both collections may help your next project earn points under the LEED® Building Rating System™ in a variety of categories.*
In addition, these non-porous surfaces, when properly cleaned, do not promote the growth of mold and mildew, making them ideal choices for homes, healthcare and food preparation facilities, schools, and offices. At DuPont, we’re always working with homeowners, designers and architects to discover sustainable new building solutions.

Construction Materials (Wood, Concrete, Steel)
Construction Materials (Wood, Concrete, Steel)
Overview
In ideal environments, most common construction materials are very durable and can last indefinitely. However, design or construction deficiencies or lack of proper maintenance can result in less-than-ideal conditions under which construction materials will degrade. Degradation can take many forms, including chemical reactions, consumption by living organisms, and erosion or mechanical wear. Traditional building materials – steel, concrete, and wood – usually deteriorate and fail via well-known mechanisms. Even innovative materials that appear on construction sites can degrade, either by these well-understood mechanisms or through exotic, sometimes surprising, reactions and processes.
Steel – Corrosion is the most common and expensive form of material degradation for construction steels, including concrete reinforcement. The U.S. Department of Transportation estimates that the annual direct cost of corrosion in the United States is a staggering $276 billion. Steel corrosion (rusting, or oxidation) is an electrochemical reaction that occurs when iron atoms loose electrons in the presence of oxygen and water. The most effective and common procedure for preventing or slowing corrosion is to prevent contact with water, either by coatings or by protecting it within a viable building envelope.
