(a)
World's first "negative emission" power plant turns CO2 into stone
For
several years an international team of scientists has been working on a novel
way to turn captured CO2 into solid minerals. The project is dubbed
CarbFix and involves bounding the CO2 to water and then pumping it 700
meters (2,300 ft) underground. This CO2 solution, on contact with the deep basalt
rock, was found to quickly form into a carbonate mineral. Read more.
Concrete, Mineral and Chemical Admixtures
(a) Nagpur Maha Metro (India) Reaches Trial Stage in a Record
Period
Six days after conducting its
first trial runs, Nagpur’s Maha Metro, conducted its first official trial run
on 30 September, 2017, making it the fastest metro project to reach the trial stage
in India. Read more
(b) Three Ways to Improve Bridges of the Future
Strategic
application of new materials, effective construction techniques and
comprehensive data capture are just a few of the tactics engineers today are
using to increase bridges' life-span. Read more.
(c) Prototypes of a
U.S.-Mexico Border Wall
The construction of prototype walls along the U.S.-Mexico
border is nearing completion, according to the Border Patrol in California. A
total of eight wall prototypes are being built in a fenced-off area in Otay
Mesa. Construction began in late September and is expected to take 30 days.
Read more.
(d) Constructing Domes by Inflating Hardened Concrete
Curved concrete shells are
impeccably strong and efficient, but, the process of making requires
large amounts of resources and planning. Even the formwork that only
contains the wet concrete needs excessive amounts of material to be built.
While the structures are incredibly efficient, the construction process is not.
The researchers at the TU Wien
university now developed a method to inflate already hardened concrete into
curved domes. Read more.
(e) Rebar-Free Concrete Core
The Rainier Square Tower
planned in Seattle will use a rebar-free concrete core, a process called
coupled steel-plate composite shear wall, to improve seismic resistance by
getting rid of rebar congestion. A model of the core design is being
constructed. Read more.
(f) Ultra-Thin
Concrete Structure
Facilitated through the use of
a novel formwork system consisting of a net of steel cables and a polymer
fabric stretched into a reusable scaffolding structure. Read more.
Books
(g) Carbon Fiber to Reinforce
Concrete Column
In June of 2016, the South
Carolina Department of Transportation (SCDOT) was in the midst of building
a new interchange at the intersection of I-85/I-385 in Greenville, S.C. During
construction, severe localized spalling was found on the cover concrete of one
column of a two-column pier supporting the I-385 northbound ramp. Read more.
(h) Tower Bridge Built with
Precast Elements
A new bridge connecting Portsmouth, N.H., and Kittery, Maine,
features what engineers believe is the first-ever use of precast-concrete
segmental towers on a vertical-lift bridge. Read more.
(i) Enhancing Construction Safety
Five things contractors need
to know in order to stay safe on the jobsite. Read more.
(j) Formwork to Speed Up Construction
MFE’s aluminium formwork solutions minimise construction and
environmental costs by casting building components in one operation.

(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 MNL-15(16) Field Reference Manual
(Formerly SP-15)
The
American Concrete Institute’s Field Reference Manual is a compilation of ACI
301-16 Specifications for Structural Concrete and additional ACI documents on
measuring, mixing, transporting, and placing concrete; concrete pumping
methods; hot- and cold-weather concreting; consolidation; and concrete
formwork. Read more.
(c) Concrete Pavement Restoration
(CPR)
The American Concrete Pavement Association (ACPA) says
planning CPR needs to begin at roughly two-thirds to three-quarters of a
pavement’s original design life. Read more.
(d) ACI 212.3R-16 Report on Chemical Admixtures
for Concrete
This
report reviews several categories and types of chemical admixtures and their
use in unique concrete technologies. Read more.
