Cement Manufacturing

Cement Manufacturing
(a) Turning Waste to Cement
A cement company based in Deerfield Beach, Titan America, has
begun turning selected waste, such as car bumpers and scrap cardboard, into
construction material. The technology reduces the amount of trash headed
to landfills, and it cuts air pollution because the materials used produce fewer
emissions than coal. The process can help Florida reach its goal of recycling
75 percent of municipal solid waste by 2020, public officials say. Read more.
(b) New Green Cement
Reduces Carbon Footprint by 40%
A new form of green cement developed in France
has the potential to reduce the carbon footprint of concrete by as much as 40
per cent. Read more.
(c) Cement Plant: Converting
Smokestacks into Profit Centers
Every kilogram of algae that Pond Biofuels produces
prevents two kilograms of CO2 from being emitted into the atmosphere. The algal
farms connected to these industrial facilities turning their smokestacks into
profit centres, all using Pond Biofuels licensed technology. Read more.
(d) LafargeHolcim: The power of the mega-merger
The idea may be out there but
LafargeHolcim has a long way to go before it actually exists. Read more.
(a) Glow-in-the-dark Roads Make Debut in Netherlands
Light-absorbing glow-in-the-dark road markings have replaced
streetlights on a 500m stretch of highway in the Netherlands. Read more.
(b) Fiber Optic Sensors to
Monitor Reinforced Concrete Corrosion
Fiber
optic sensors can detect the moisture, expansion, and cracks in reinforced
concrete, enabling engineers to observe a structure's condition and predict its
lifetime. Read more.
(c) Solidia Technologies Finds
Potential Savings of 2 Billion Tons of Water Per Year
New CO2-curing technology reduces water consumption
by up to 80%, CO2 emissions by up to 70%, and curing time to one day. Read more.
(d) Future of
Skyscrapers
With tall buildings growing ever higher, it is
becoming increasingly critical to optimise structural systems in order to
ensure strength and stability. The rise of composite megacolumns could be the
most effective answer. Read more.
(e) World's First Energy Positive Building
The world is
ready for an even fresher catchphrase than “net zero” buildings (NZB) to
describe environmentally friendly buildings. Say hello to Norway's Powerhouse Kjørbo,the
world’s first “energy positive building" (EPB) or “net positive"
building. Read more.
(f) Carbon Capture can Revolutionise Green
Construction
Past research has shown that treating concrete
with CO2 can improve its strength, reduce water absorption, improve resistance
to chloride permeability and improve freeze-thaw performance. Carbonation never
compromises quality, colour or texture. Read more.
(g) Radioactive Waste in Concrete Casks
Dozens of containers of
radioactive waste from Los Alamos National Laboratory are being packed as a
precaution into concrete casks at a temporary storage facility in West Texas.
Read more.
(h) Making Infrastructure Maintenance Cost-effective, Sustainable
Discussed in this article are
the use of robots for pipe-lining technology; a cement additive that fortifies
concrete's strength by as much as 40%; and a spray-on synthetic
high-performance fiber that contains fiber optic sensors, which can send
signals to equipment for structural condition monitoring. Read more.
(i) Super Skinny
Skyscraper Trend
Modern construction materials
and structural and design technologies are enabling builders to construct tall,
narrow towers on small plots. 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 305R-10 Guide to Hot Weather Concreting
Environmental factors, such as high ambient temperature, low humidity,
high wind, or both low humidity and high wind, affect concrete properties and
the construction operations of mixing, transporting, and placing of the
concrete materials. This guide provides measures that can be taken to minimize
the undesirable effects of these environmental factors and reduce the potential
for serious problems. Read more.
(c) ACI 305R-10 Guide to Hot
Weather Concreting
Environmental factors,
such as high ambient temperature, low humidity, high wind, or both low humidity
and high wind, affect concrete properties and the construction operations of
mixing, transporting, and placing of the concrete materials. This guide provides
measures that can be taken to minimize the undesirable effects of these
environmental factors and reduce the potential for serious problems.

(d) ACI 523.3R-14: Guide for
Cellular Concretes Above 800 kg/m3
This guide addresses the
materials, properties, design, production, and placement of cellular concretes
with as-cast densities greater than 50 lb/ft3 (800 kg/m3). The usual density
range of cellular concrete is 20 to 120 lb/ft3 (320 to 1920 kg/m3). Cellular
concretes in the lower portion of this range are used for many applications,
such as roof thermal insulation and geotechnical fills. Cellular concretes in
the higher density range are used for cast-in-place, precast applications and
nonstructural floor fills. Read more.
(e) Concrete Repair to EN 1504: Diagnosis,
Design, Principles and Practice
Authors:
Michael
Raupach, Till Büttner Published: May 15, 2014 by CRC Press
Presents
a systematic approach to concrete repair based on EN 1504. Outlines the main
methods in detail. Provides a large number of case studies. Read more.
