Cement Manufacturing
(a) Recycling CO2 generated
as fuel in cement production
LV technologies public company limited is working towards
usage of carbon emission as a fuel with the latest technology of using
microalgae which trap CO2 and convert it into a dry fuel. Additionally,
Pond Biofuel from Toronto has been associated with a cement maker (St. Marys)
of Canada to work towards capturing CO2 and using it over and over again as a
fuel for manufacturing cement. Read more.
(b) Heat recovery solution
for cement plants
Cement plants can reduce emissions and supply up to 30% of their own energy needs by using waste heat recovery technology says a new report by the World Bank Group’s private sector arm, International Finance Corporation and the Institute for Industrial Productivity. Read more.

(a) RFID
to Monitor Concrete Curing
Accurately monitoring the curing of concrete can
be critical on large construction projects. Wired sensors can be too cumbersome
for large projects. The system, installed when the TransBay Transit Center
project launched approximately two years ago, consists of active ultrahigh-frequency (UHF) RFID tags with built-in sensors, as well as
handheld readers and software to interpret the collected temperature data.

(b) Net-zero Energy Buildings
The General
Services Administration's Net-Zero Energy Task Group is planning to produce a
draft letter with clear goals and guidance for net-zero energy buildings by September
2014. Read more.
(c) Pervious Concrete
Its use can eliminate the need
for retention ponds or other mitigating elements and this increases the amount
of usable land and reduces project costs. Read more.
(d)
Benefits of Autoclaved Aerated Concrete (AAC)
Lightness, durability,
energy-efficiency and resistance to fire. Read more.
(e) Pre-tensioned Concrete Bridge Support Cuts Construction Time
A new, rocking, pre-tensioned
concrete bridge support system has been developed by the University of
Washington that reduces on-site construction time and minimizes earthquake
damage. Read more.
(f) Safe and Sustainable
Concrete One World Trade Center
To meet the strength requirements,
the design and engineering team relied on a highly specialized concrete mix
that included Lafarge Portland Type I/II and NewCem slag cements, as well as
other supplementary cementitious materials. Read more.
(g) State-Of-The-Art Bridge Design
The article showcases the
Institution of Structural Engineers' five bridge nominations from around the
world that Kelsey Campbell Dollaghan says show us what's going on in current
bridge design innovation. Read more.
(h) Performance-Based Design Guide for Buildings
This approach is
expected to help building owners achieve better building performance. The guide
lets a building owner analyze the benefits of different levels of performance
at various levels for a new structure or renovation. Once a performance level is
chosen, the design-construct team can determine the best ways to meet those
goals. Read more.
(i) China’s
Pre-Certified LEED Gold Building
One of the longest buildings in China, Riverside 66, is scheduled to
open to the public this fall. The curved building is more than 1,000 feet long,
and has been pre-certified LEED Gold. Readmore.
(j) Beauty and Value in Roller Compacted Concrete
Over time, RCC has proven to be a
much more durable solution under heavy loads and high traffic. It also requires
minimal maintenance when compared to asphalt. Read more.
(k) Seven New Materials for Future Construction
As architects and engineers face
bigger challenges — from earthquakes to dwindling resources to sheer cost — a
new generation of smart materials is emerging. Read more.
(l) NIST Megacities Carbon Project
Urban areas generate at
least 70 percent of the world’s fossil fuel carbon dioxide emissions, but
gauging a city’s carbon footprint remains difficult due to the lack of
effective measurement methods. The project aims to change that by developing
and testing techniques for both monitoring urban areas’ emissions and
determining their sources. Read more.
(m) Building
Information Modeling (BIM)
Ten common steps to BIM that help
to both accelerate the process and reduce the disruption that can accompany
change. 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 213R-14 Guide for
Structural Lightweight-Aggregate Concrete
The guide summarizes the
present state of technology, presents and interprets the data on
lightweight-aggregate concrete from many laboratory studies and the accumulated
experience resulting from its successful use, and reviews performance of
structural lightweight aggregate concrete in service. Read more.
(c) ACI Publication: Principles of Reinforced
Concrete Design
Principles of Reinforced
Concrete Design draws a clear distinction between fundamentals and professional
consensus. This text presents a mixture of fundamentals along with practical
methods. It provides the fundamental concepts required for designing reinforced
concrete (RC) structures, emphasizing principles based on mechanics,
experience, and experimentation, while encouraging practitioners to consult
their local building codes. Read more.
(d) ACI 305.1-14 Specification for Hot Weather
Concreting
This
reference specification provides requirements for hot weather concreting that
the architect/engineer can apply to any construction project involving hot
weather concreting by citing it in the project specification. Read more.
