Cement Manufacturing
(a) Alternative Fuels at Cement Hranice
In its first few months of
operation, the kiln has worked with a specific heat consumption of
3410 kJ/kg of clinker at 4000 Nm3/h bypass. The average coal/alternative fuel ratio
is now 56:44, achieving a saving of CZK9.5/GJ on thermal energy costs. Read more.
(b) Mass Balance of Dioxins over a
Cement Kiln in China, Yeqing Li, et. al. Waste Management, Volume 36,
February 2015, Pages 130–135
The cement production process may be a potential source of polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs, “dioxins”), due to the widespread distribution of dioxins and potential precursors in raw materials and to conditions favorable to de novo formation in the heat exchangers.

(a) World’s Longest ‘Flat
Pack’ Arch Bridge
Civil Engineers at Queen’s University Belfast have developed
the world’s longest ‘flat pack’ arch bridge. Made up of 17 units (1m
wide) of pre-cast concrete, each weighing 16 tons, the bridge will take less
than a day to install using a 200-300 ton crane in association with a lifting
beam also designed and built in Northern Ireland. Read more.
(b) PICP can Mitigate Runoff
Concerns
Permeable interlocking
concrete pavement (PICP) can help help solve the problem of stormwater management. PICP cleans,
detains and reduces the amount of stormwater which has to be handled and has
been used effectively at several sites, although care must be taken to arrive
at the proper design. Read more.
(c) Vertically Stacked Concrete Blocks in Construction
Located at the heart of Vietnam’s Ha Tinh city, H&P
architects has
completed a 1,300 square meter office building on a relatively small budget of
$500,000 USD. The project adheres to three key principles: a
distinctive design, quick construction time and a minimum overall cost. Readmore.
(d) Innovative
Techniques are Helping to Create World's Largest Dams
Innovation at two roller
compacted concrete dams in Ethiopia and a conventional, vibrated concrete one
in China. Read more.
(e) Off-site Construction Techniques Gain Momentum
Off-site construction limits site construction as much as possible in favor of building the majority of a structure at a manufacturing facility and then assembling on site later. Read more.
(f) Tough Two-span Bridge Remains Usable after
Severe Shaking in Quake Engineering Test
Experiment by University
of Nevada, Reno, shows new techniques and materials, we will usher in a new era
of super earthquake-resilient structures. Read more.
(g) Concrete to Guard Against Corrosion of
Steel Pipe
A $146 million,
5.3-mile-long water tunnel in the metro Washington, D.C., area is complete. It
is the largest infrastructure project in the agency's history and required
boring through solid bedrock up to 200 feet underground. A steel pipe runs
through the bedrock tunnel, and a coating of concrete guards against corrosion. Read more.
(h) Innovations Featured in Oregon Bridge Replacement
Prefabricated
steel arches, liquid nitrogen-cooled concrete and two perched box caisson river
piers are facilitating the construction of a new $307.5-million Sellwood Bridge
in Portland, Oregon. Read more.
(i) Building Information Modelling is
Transforming Construction Industry
Building Information Modelling –
better known as BIM – is the future of the construction industry. Read more.
(j) Photocatalytic Concrete
A bridge spanning a major road in Barcelona will be coated in
photocatalytic concrete, allowing it to "eat" pollution. The material
uses energy from the sun to break down polluted air into little more than
oxygen and water, keeping the bridge and air around it cleaner. 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 329R-14 Report on Performance-Based
Requirements for Concrete
This
report discusses the differences between performance and prescriptive
requirements for concrete, and provides information on developing performance
requirements as an alternative to the current prescriptive requirements in
codes and specifications. Readmore.
(c)
ACI 306R-10: Guide to Cold Weather Concreting
The American Concrete
Institute's 306R-10, Guide to Cold Weather Concreting, helps guide concrete
placements in cold weather to optimize performance. The document gives
recommendations and shows that previous temperature guides have been too
conservative. However, the two authors, both concrete professionals, suggest
that people use the guide as a tool, not a rule. Read more.
(d) 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. This guide describes RCC and how it works as a paving material,
how it compares to concrete pavement, its common uses and benefits, and
potential limitations compared to other paving materials. Read more.
(e) Benefits of Post-Tensioning
This article looks
at the differences between pre- and post-tensioning of concrete. It delineates
the advantages found in post-tensioning, including reducing the amount of steel
and concrete needed, creating thinner slabs that can bear heavier loads and offering
greater layout flexibility. Read more.
