(a) Non-Portland Bulk Cement
CeraTech has produced a cement system with a virtually
zero-carbon footprint, with 95% reduction in the use of virgin resources and 50%
reduction in the use of water. The cement system comprises 95% recycled fly ash
and 5% liquid additives, meeting ASTM International C1157, as a hydraulic
cement system. Read More.
(b) Malaysia’s
CIMA Turning to Alternate Fuel
The Cement Industries of Malaysia (CIMA) has set its sights on using
alternative fuel to power its cement plants, reports NST. It is set to
be the first cement manufacturer in the country to use tyres and biomass waste
as an alternative source of fuel. Read more.
(c) UK’s First Low Carbon Electricity Generator from
Lime Kiln Exhaust
Reduces the sites
CO2 emissions by 1,610 tonnes. Recovers 4MW of low temperature waste heat from
the rotary kiln exhaust and convert it to 0.5 MW of low carbon cheaper
electrical power. Annual energy saving measures of 3,000 MWh. Attractive return
on investment. Read more.
(d) Lafarge Cement’s Carbon Dioxide Reduction Project
Electrochemical reduction
technology at one of Lafarge cement plants will convert carbon dioxide
emissions into useful chemicals. Read more.
(a) Innovative Roller Compacted Concrete Dam Opens in
Puerto Rico
The
formal completion ceremony for the $386-million Portugués Dam on Feb. 5 marks
the end of a long odyssey to solve the flood-control issues that imperil the
Caribbean island's second-largest urban area. The 220-foot high structure is
the first single-centered, roller compacted concrete (RCC), thick-arch dam,
ever attempted by the US Army Corps of Engineers, according to project
officials. Read more.
(b) Benefits of Portland Limestone Cement (PLC)
based Concrete
Results of the study indicate that, relative to OPC, PLC
shows a 10% to 12% improvement in environmental performance across similar
concrete mix designs. These improved results were found to be proportional to
the quantity of cement required in the mix design, suggesting that greater
improvements are possible, especially if Canadian concrete standards were to
allow greater PLC substitution levels as European standards do. Read more.
(c) World’s Tallest Residential Building
From the core backbone to the outside perimeter is
about 30ft that is free of any columns, beams or any structural elements so you
can have partitions as you wish or if someone wants to take the entire floor
and doesn’t want partitions - he wants a loft - people can use the entire floor
as they desire. View the video. Read more.
(d) Tech Tool to Inspect Heavy Construction Equipment
The technology "can also benefit public infrastructure
by extending the life of aging systems such as bridges, rail and roadways,
power plants, sewage systems, or undersea communications cables. Read more.
(e) Sensors to Detect Structural Weaknesses before
Disaster
The sensors would not only
identify damage after it happens, but would also "predict" the
failure before it occurs. Read more.
(f) World’s
Next Tallest Building
How to pump wet concrete more than half a mile into the
sky. Read more.
(g) Urbanism
through Vertical Cities
With the world’s
urban population growing at an unprecedented rate, high-rise buildings will
feature prominently in future cities. The concept of the vertical city could be
a solution to the challenge of high-density urbanisation. Read more.
(h) NIST Zero-Energy House Gives Back to the Grid
Over the first six months
in their special, new, four-bedroom home in suburban Maryland, the Nisters, a
prototypical family of four, earned about USD 40 by exporting 328 kilowatt
hours of electricity into the local grid, while meeting all of their varied
energy needs. Read more.
(i) Smog-Eating Facades
The treatment is a thin layer of titanium dioxide (TiO2), a powder or
liquid that can be applied to glass, concrete, metal, or fabric; when sunlight
hits the chemically treated surface, a process begins that oxidizes organic
matter, turning pollutants into water vapor and CO2. Read more.
(j) Concrete Blocks in
Hurricane-Resistant Construction
The strength of
the block walls is derived from internal steel support bars and the vertical
concrete pour through the hollow blocks at strategic parts of the walls,
according to this article. Read more.
(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 506.2-13 Specification
for Shotcrete
This specification
contains the construction requirements for the application of shotcrete. Both
wet- and dry-mixture shotcrete are addressed, as well as fiber-reinforced
shotcrete. The minimum standard for materials, properties, testing, and
application are covered. Read more.
