Cement
Manufacturing
(a) ORC
Generators
The Organic
Rankine Cycle (ORC) expander converts the recovered thermal energy from a low
grade waste heat source into kinetic energy, which is then converted into
electrical energy by a generator. Read

Concrete, Mineral and Chemical Admixtures
(a) Precast Concrete Facade Selected for 33-Storey Building
British architect
David Chipperfield designed The Bryant, a
33-story residential building in New York City. In a video, Chipperfield
discusses the design process and why precast concrete was used for the facade.
Read more.
(b) Sustainable Design of Structures
The discussion and implementation of sustainable design is a reaction to global environmental
crises, rapid growth of economic activity and human population, depletion of
natural resources, damage to ecosystems, and loss of biodiversity. Read more.
(c) Longest
concrete high-speed rail span built in Spain
A 3,268-foot-long concrete
bridge to be used for a high-speed rail line is under
construction over the Almonte River in Spain. The main span for its arch is
nearly 1,260 feet long, which will make it the largest span of HSR in the
world. More than a dozen cast-in-place, post-tensioned concrete box girders are
being used. Read more.
(d) Conductive Concrete for De-Icing
Civil engineering professor
Chris Tuan developed a concrete mix with steel shavings and carbon particles
that conducts electricity to safely melt ice and snow. The concrete has been
used on the 150-foot Roca Spur Bridge in Nebraska and has de-iced it for more
than 10 years. Now the Federal Aviation Administration is considering its use
on airport tarmacs. Read more.
(e) Machine to Test
Durability of Concrete Pavement
As part of VDOT’s accelerated
pavement testing program, the new machine, called a heavy vehicle
simulator (HVS), will test pavement by running a heavy wheel assembly back and
forth across it. The 54-ton machine can produce the same wear and
tear that cars and heavy trucks do to highways. Read more.
(f) Remarkable Bridges
Around the World
Impressive bridges around the
world have been created using a variety of techniques and materials. This
article looks at 20 of the "most impressive," including the
3,000-foot-long Magdeburg Water Bridge in Germany and a swinging pedestrian
bridge in the UK. Read more.
(g) High Density Concrete
Tunnel boring is complete in
the UK's massive Crossrail project, and a dense concrete called MagnaDense is
being installed in part of the slab. The material minimizes noise and is twice
as dense as normal concrete because of its natural iron ore content. Readmore.
(h) Argos delivers first ready
mixed concrete with recycled carbon dioxide
Argos has produced America’s first ready mixed concrete made
with recycled carbon dioxide thanks to a newly formed agreement between Argos
of Atlanta, Georgia, and CarbonCure Technologies of Nova Scotia, Canada.
Read more.
(i) Concrete to Enhance
Acoustics
Valley Public Radio in
California is constructing a performance studio and wanted to get just the
right acoustics. The design includes walls with no right angles, which helps to
reduce sound deflection, and concrete pads on the floor that are
"acoustically isolated" from the structure and one another. In
addition, the concrete floor sits on a high-tech acoustic material. Read more.
(j) Solar Roadway
France is moving forward with
a "Positive Energy" initiative to add solar panels to 621 miles of
road. The panels are glued onto the roadway and can handle the weight of
six-axle vehicles. This stretch of road could collect enough energy for 5 million
people. A Dutch company has already used solar panels on 328 feet of road in
Holland. Read more.
(k) Lean Construction Improves Efficiency
Lean construction
efficiencies stand as strong contributors to better productivity and greater
profitability. But it takes a certain mindset to pull it off and to have the
greatest level of success. Read more.
(l) 3D Printed Public Housing
Singapore has been one of the busiest locations in the 3D
printing industry lately. The city-state has made 3D printing a major priority,
with several large centers and organizations dedicated to the technology. Read more.
(m) Movable Scaffolding
The first section
of the Mersey Gateway Project viaduct in the UK is done. It's being built with a movable
scaffolding system that acts as a giant concrete mold. The first section took
1,499 cubic yards of concrete and 34 hours. Read more.
(n) Stenciled Concrete
Stencils can add a decorative
touch to concrete floors, basements, walkways, patios and garages. Read more.
(o)
Decorative Concrete
The growing number of
aesthetic options with decorative concrete are making the material
sought-after, and having a recognized brand matters. Read more.
(p) Concrete Corrosion in
Port Structures
Corrosion has the power to slash the life span of
port structures. Read more.
(q) High strength Concrete for Super-Slim Tall Structures
Super-slim, supertall
skyscrapers are gaining in popularity as the amount of buildable land
diminishes and as advances in technology and materials push engineering to new
limits. Read more.
(r) Color Problems with Precast Concrete
Efflorescence on precast,
colored concrete walls at a $117 million event center in Sioux Falls, S.D., is
causing concern, even though it's a natural process. Read more.
(s) NIST Net-Zero
House
Tweaking ventilation and
temperature control systems, along with a mild winter, helped the experimental
net-zero-energy house at the National Institute of Standards and Technology
(NIST) quadruple the amount of surplus energy it sent to the power grid during
its second year-long demonstration. Read more.
(t) Shotcrete to Battle El Nino
California is spending $8
million to ward off El Nino and prevent erosion along the Pacific Coast
Highway. Among the projects are one in Malibu where 1,500 cubic yards of
shotcrete were sprayed onto a hillside and then reinforced with thousands of
tons of boulders to create a 1,200-foot-long wall between it and the Pacific
Ocean. Read more.
(u)
Strengthening Concrete with Crystalline Coating
The application of crystalline materials as external
coatings can serve to prevent damage to existing concrete
structures by entering and filling the very channels of
ingress for corrosive chemicals - the pores and cracks that permeate
the building material. 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) Innovations in Portland Cement Manufacturing, 2nd Edition: Portland Cement Association: Product Code: SP400 Comprehensive review of current innovations in the manufacture of portland and blended cement is included in this two-volume set. Read more.
(c) ACI CCS-0(16) Concrete Fundamentals
This is one of six books in the Concrete Craftsman Series
published by the American Concrete Institute. This book is intended for anyone
who wants an introduction to concrete and concrete construction. Craftsmen in
the concrete field may find it particularly useful as a guide for good practice.
