Cement Manufacturing


(a) Bioglycerol as a Multipurpose Grinding Additive for the Manufacture of Cement
Bioglycerol, or crude glycerol, is impure glycerol obtained as a by-product in the biodiesel industry. Researchers now show that it is possible to employ bioglycerol as a multipurpose grinding additive for the manufacture of cement, with better performance than pure glycerol. Cements with bioglycerol are produced with lower energy consumption and the finished concrete structures have significantly better mechanical properties and corrosion resistance. Read more.


(b) Cement Company to Build Conveyor System to Transport Limestone
Construction is set to begin on a 4.7-mile conveyor system to transport limestone from Lehigh Cement Co.'s New Windsor quarry to its Union Bridge facility. Read more. 


(c) Carbon Capture from Cement Production
Membrane-based technology developed at the Norwegian University of Science and Technology (NTNU) is one of four technologies that may be used in a full-scale CO2 capture project – in a cement factory. Read more.


Concrete, Mineral and Chemical Admixtures


(a) Precast concrete for a highway project in Toronto
Will shave eight years off the project’s time frame but add at least $318 million more to the anticipated $1-billion-plus cost. However, the project is expected to save at least $2.4 billion due to less congestion. A report recommended using ultrahigh-performance concrete because it is four times stronger than conventional concrete which reduces life cycle costs. Read more. 


(b) Ferry Terminal Built on Floating Concrete
A 262.5-by-65-foot floating concrete pontoon is the base of a ferry terminal in Tasmania, Australia. It's anchored to the ocean floor by cables. Read more.


(c) 3D printing is Changing Global Construction Industry
The concept of 3D printing has been hovering around for some time now. The actual use of 3D printing and its adaption into the construction industry is now starting to become a reality. Architects and contractors around the world are beginning to build the first 3D residential structures including houses and apartment buildings. Read more.


(d) World's Seven Sustainable Buildings
Fortune created a list of seven buildings noted for their sustainable design and construction. Included in the list are Norway's Powerhouse Kjorbo, a renovated building that became energy-positive; Seattle's Bullitt Center, which claims to be net-zero in water, energy and carbon; and Pittsburgh's Tower at PNC Plaza, with a solar chimney. Read more. 


(e) Lafarge & Solidia Commercialize New Low-Carbon Solution for the Construction Sector
Lafarge will offer a complete solution - sustainable cement and CO2-cured concrete - in partnership with Solidia. Read more.


(f) Precast Construction Technique Reduces Delays and Costs.
The Wisconsin Department of Transportation used precast and prestressed concrete elements on a bridge project, significantly reducing construction time and cost. Read more.

(g) Story of Hoover Dam
Constructing the Hoover Dam was an important economic tool during The Great Depression and helped tame the Colorado River. This article looks at the engineering and building feats involved in creating the 1,244-foot-long, 726.4-foot-high dam with a 660-foot wide base, and notes that it took 3,250,000 cubic yards of concrete to complete. Read more.

(h) Floating Bridge in Seattle

The world's longest floating bridge will soon be eclipsed by a newer, longer span a few feet away on Lake Washington in Seattle. Read more.

Books
(a) Mineral Admixtures in Cement and Concrete, Author: Jayant D. Bapat, CRC Press, Taylor & Francis Group 
Written for engineers, this book focuses on how to make more workable and durable concrete using mineral admixtures. For each mineral admixture, the book looks at manufacturing and processing, physical characteristics, chemical and mineralogical composition, quality control, and reported experiences. It also examines the provisions of national standards on the admixture’s addition to cement and concrete. Offering a deeper understanding of mineral admixtures, it encourages engineers to more effectively use these and other wastes in cement and concrete to support more sustainable growth of the cement and construction industry. Read More.


(b) ACI 327R-14 Guide to Roller-Compacted Concrete Pavements
This guide provides owner-agencies, contractors, materials suppliers, and others with a thorough introduction to roller-compacted concrete (RCC) and its many paving applications. Readmore.


(c) ACI 305R-10 Guide to Hot Weather Concreting
Environmental factors, such as high ambient temperature, low humidity, high wind, or both low humidity and high wind, affect concrete properties and the construction operations of mixing, transporting, and placing of the concrete materials. This guide provides measures that can be taken to minimize the undesirable effects of these environmental factors and reduce the potential for serious problems. Read more.
