Concrete, Mineral and Chemical Admixtures
(a) Wood as Aggregate in Concrete
Researchers in Switzerland
have taken the modern approach to using both wood and concrete for building one
step further and are using wood as the aggregate in concrete. Stress tests on
the load-bearing concrete with more than 50% wood has yielded positive results
for wall, slab and structural elements. Read more.
(b) Robotics in Construction
Robotics
in use in the field today is helping to pave the way for future builders by
showing the technology's potential to aid productivity and eliminate rework. Read more.
(c) Rigid Concrete
Pavement is more Flood Resilient
Road authorities should consider changing their roads to
flood-resilient pavements in the future. Read more.
(d) Carbon Fiber Strips to Strengthen
Bridges
The Arizona Department of Transportation has used what
it calls "a space-age technique" to repair and strengthen concrete
girders on two freeway bridges in Phoenix. Read more.
(e) World's Tallest Roller-Compacted Dam
The 318-foot tall dam — the
tallest built using a new concrete construction process — nearby
Lake Hodges pump station, 11-mile San Vicente Pipeline and newly raised San
Vicente Dam can together store six months of water supply in case the region is
cut off from Colorado River aqueducts. Read more.
Over
250 precast concrete components were produced for the project, including
precast concrete panels, beams and arched spandrels. Precast concrete wall
panels provide both load-bearing structural capabilities and the desired
architectural finish for this house of worship. Read more.
(g) Offsite Construction: Current Trend
Increasing collaboration
between off-site manufacturers and contractors is the biggest among five trends
in construction. Read more.
(h) First Commercial Building Project to Use 3D Printing
Crossrail in London is the first commercial building project
to use 3D printing. Read more.
(i) Seven Steps to Boost
Productivity in Construction Sector
McKinsey research finds seven levers
can fix construction’s productivity problem, but they require a new approach
from all players. Read more.
(j) Rise of the Prefabricated Construction
Prefabricated construction is moving to the forefront of the
construction industry, because of a worker labor shortage and a need for
efficiency. Since modular structures do not allow for modification at the site,
they are ideally suited for student housing, education facilities, hospitals
and hotels. Read more.
(k) Seattle Rebuilds
Seawalls
The 3,700-ft, $410-million wall is designed to last more than
75 years. It will be as much as 15 ft west of the site of the current wall to
accommodate construction design that protects against a 100-year wave event,
tsunami waves and surges, while building additional space for habitat.
Read more.
(l) Gray Coating to Reduces
Heat in Concrete Jungle
Heat can become trapped in
urban settings, a phenomenon knows as heat island effect, and Los Angeles and
other cities are looking for ways to reduce it. CoolSeal, a gray pavement
coating designed to reflect the sun, has shown in a pilot project that it can
reduce temperatures by as much as 10 degrees. Read more.
(m) Hurricane
Building Codes Work
Homes built to stricter standards fared better in the storm, in Florida. 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) EN 16757:2017
Sustainability of construction works - Environmental
product declarations - Product Category Rules for concrete and concrete elements.
Read more.
Teaching, Training and Research

(b) Concrete to Help Solve the Problem of Air Pollution
Sulfur
dioxide, a major contributor to air pollution, is removed from the air by
concrete surfaces, new research shows. Read more.
(c)
Floating Tunnel
Series of experiments from the
Norwegian University of Science and Technology’s (NTNU) Centre for Advanced
Structural Analysis, or CASA, could pave the way for an entirely new type of
water crossing: submerged floating tunnels. Experiments in a shock tube at
CASA’s research laboratories show that concrete can tolerate much more pressure
than previously thought. Read more.
(d) Concrete Sensors Measure Strength
and Humidity
The sensors are tied to
reinforcing steel within the concrete slab or formwork which enables wireless
and continuous monitoring of concrete temperature and strength using Bluetooth
technology to transmit data to a smartphone application. Read more.
