Checklist for the key factors to
consider when selling bagged cement. Read more.
(a) Unhappy State of U.S. Bridges and Highways
On a national scale, 66,749 bridges out of 607,380 are
structurally deficient, representing one-third of the total bridge-deck surface
area. Read more.
(b) Recycling Roads,
Conserving Construction Materials
The old asphalt and base materials
are pulverized, mixed with cement and water, and compacted to produce a strong,
durable base for either an asphalt or concrete surface. Read more.
(c) Evaluating Concrete Piles with Ground Penetrating Radar (GPR)
According to the report
prepared by Florida Department of Transportation, GPR technique has been
widely used in Florida. Read more.
(d) Maturity Method for
In-Place Strength Measurement of Concrete
The maturity method is a
technique to account for the combined effects of time and temperature on the
strength development of concrete. Read more.
(e) Precast Concrete Dam Built
as Prototype
French Development
Enterprises, Oldcastle Precast and GEI Consultants spent 3.5 hours constructing
a prototype of a modular, precast dam using six interconnected, 27,000-pound
concrete blocks anchored to a foundation. Read more.
(f) Precast Concrete
Reduces Construction Time
Reconstruction of the Peoria Street pedestrian bridge
spanning I-190/Congress Parkway and adjacent to the rebuilding of the busy
circle interchange in downtown Chicago, IL, capitalized on innovative precast
concrete Accelerated Bridge Construction (ABC) techniques that allowed for high
strength, thinner bridge sections and reduced delays and lane closures. Read more.
(g) Chernobyl's Gigantic
Radiation Shield
A concrete-and-steel arch is
being moved into place to shield the Chernobyl nuclear reactor and its
deteriorating concrete sarcophagus. Read more.
(h) Bridge to Withstand Earthquakes
A new bridge that will carry
traffic from State Route 99 into Seattle is designed to survive earthquakes and
seismic shocks. Read more.
(i) ConcreteTetrapods to Slow
Storm Effects
Japanese engineers are
reinstalling tetrahedral concrete structures called Tetrapods to help slow
erosion and protect coastlines from the effects of large waves. Read more.
(j) ACI 201.2R-16: Guide to Durable Concrete
This guide describes specific types of concrete
deterioration. Each chapter contains a discussion of the mechanisms involved
and the recommended requirements for individual components of concrete, quality
considerations for concrete mixtures, construction procedures, and influences
of the exposure environment, which are all important considerations to ensure
concrete durability. 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-ITG-9R-16: Report on Design of Concrete
Wind Turbine Towers
This report examines the benefits of the design of concrete
towers for land-based wind turbines with heights in excess of 325 ft (100 m),
in comparison to those of round steel tubular towers. These benefits include
reduced cost, increased stiffness, and superior service life performance.
Construction alternatives, design criteria, design methodologies, and guidance
for preliminary design of concrete towers are presented. Read more.
(c) ACI 232.3R-14 Report
on High-Volume Fly Ash Concrete for Structural Applications
This report presents technical information to support the use
of high-volume fly ash concrete for structural applications. The advantages and
limitations of high volume fly ash concrete are discussed, and the
characteristics of the fresh and hardened materials and the durability of the
material to various aggressive environments are covered. Field applications are
presented along with sustainability features. Read more.
Teaching, Training and Research
(a)
Professional Training Course on Durable, High Performance Cement & Concrete
with Mineral & Chemical Admixtures
Dr J D Bapat offers professional training
course on “Durable, High Performance Cement & Concrete with Mineral &
Chemical Admixtures ”. Two-day course is useful for engineers working in cement
plants, cement and admixtures marketing, construction sites, higher education.
Duration and content: tailor-made as per participants’ requirement. Venue: as
per sponsor’s preference. Download brochure. Read more.
(b) Computational Model to
Evaluate Structural Health after Vibrations
Researchers at MIT have developed
a computational model that makes sense of ambient vibrations, picking out key
features in the noise that give indications of a building’s stability. Read more.
(c) Tracking Damage in Concrete
Water will seep into cracks in
concrete, eroding the material from within, but can also carry other
substances—like road salt—into a foundation, speeding up damage or corrosion to
steel reinforcement. Read more.
(d) Concrete as Substantial Carbon-Sink
Concrete structures are a substantial
absorber of carbon emissions – offsetting some of those emitted during cement
production, says a new study. Read more.
(e) Carbon Fiber Concrete
Instead of the traditional iron grates, the concrete contains
carbon fibers. Those fibers are even more durable than steel and don't corrode. Read more.
(f) Swiss 3-D Printing
Innovation Prize
Researchers at
ETH Zurich have won the Swiss Technology Award 2016 for developing concrete
form moulding and reinforcement innovations using 3-D printing robotic arms to
create a mesh mould to hold shape and provide structural strength, according to
3-D Printing Industry. Read more.
(g) Five Innovation Changing
the Concrete Industry
Concrete technology is
witnessing advancements like never before. It’s expected to help the
construction industry in many ways, with some of the most biggest advantages
being faster completion of projects and a whole new lot of design options to
choose from. Read more.
(h) Fiber Optics Makes Concrete
Glow
Who knew concrete could be so
cool? The Bavarian city of Bad Staffelstein recently unveiled a newly-renovated
thermal bath topped with a light-transmitting concrete cave. Read more.
