Cement
Manufacturing
(a) Solar power for
LafargeHolcim in Jordan
The plant will provide up to a quarter of the energy needs of
the Rashadiya cement plant. Read more.
Concrete, Mineral and Chemical Admixtures
(a) New
ASTM Standard for Recyling Fresh Concrete
The new standard (C1798, Specification for Returned Fresh
Concrete for Use in a New Batch of Ready-Mixed Concrete), developed by ASTM’s
committee on concrete (C09), covers process, verification, and record-keeping
procedures for such recycling. Read more.
(b) Solution Sought to Fix Cracks in Concrete Levee
The cracks are on the U.S. side of
the Rio Grande River between the Gateway International Bridge and Lake Brown.
Over the years, they have shifted and opened up. Read more.
(c) Sandwiched Concrete Slabs
The entire building will be constructed out of new system of
sandwiching two large-scale concrete slabs in a way that expedites construction
and shifts all the load-bearing requirements to the exterior walls. Read more.
(d)
Large Number of U.S. bridges Structurally
Deficient
Report by the American Road
and Transportation Builders Association states that 55,710 bridges in the US
are structurally deficient, and the cost of providing necessary repairs to the
structures will increase as time passes. Read more.
(e) Advancements in Concrete Paver Technology
Among the many
different benefits: The new machines have better control panels and can provide
more flexibility and application switching. Read more.
(f) Special Concrete at UK Rail
Project Minimises Noise
Track slab construction on the crossrail project
is seeing the use of an innovative heavyweight concrete mix to minimise noise
and vibration. Read more.
(g) Colored Concrete
The Arizona Department of Transportation (ADOT) has placed a
series of painted concrete columns and walls near the southwest corner of 59th
Avenue and Washington Street in Phoenix to test the aesthetics of shapes and
colors for the Loop 202 South Mountain Freeway. Read more.
(h) Prefabricated Bridge
The
Arizona Department of Transportation will be installing the state’s first
prefabricated bridge along Oatman Highway. The 110-foot bridge is being
manufactured in Phoenix and then will be transported in sections to the site in
northwestern Arizona. Read more.
(i) Three Gorges Dam
The Three Gorges Dam in China
cost $25 billion to build, required 36.6 million cubic yards of concrete and
created 40,000 construction jobs. Read more.
(j) Vibration Data to Detect Bridge Defects
The Minnesota Department of
Transportation is using vibration data collected at the Interstate 35W St.
Anthony Falls Bridge to detect structural defects. Read more.
(k) Precast-Slab
Concrete Highway
The California Department of
Transportation will use 6,500 precast concrete pavement slabs for 9.7 miles of
Interstate freeway, I-210, North of Los Angeles. Read more.
(l) Concrete for Power
Cables
Powercrete, developed by Hanson’s
German parent HeidelbergCement, is a heat conducting concrete that helps to
dissipate the heat generated by high-voltage and ultra high-voltage electrical
cables. Read more.
(m) Oroville Dam Disaster
On Feb. 7, 2017, the
floodgates at the Oroville Dam in California were opened, sending 55,000 cubic
feet of water per second down a concrete spillway. The amount was only 18% of
the volume that the spillway was engineered to withstand, but it crumbled under
the pressure, and "design flaws, misunderstood geology and poor maintenance
over the years" could be factors in the failure. 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.
