Cement
Manufacturing
(a) World’s Tallest Bucket Elevator
With a distance between centers of 175.3 m, this is currently
the tallest in the world. Read more.Concrete, Mineral and Chemical Admixtures
(a) 5 Million Gallon Concrete Water Tank
Port Townsend,
Wash., is building a 5 million-gallon concrete water-storage tank designed to
withstand an earthquake. The reservoir's walls will be 39 feet tall. Read more.
(b) Movable Scaffolding
Sections of the
replacement for the Gerald Desmond Bridge have begun with a movable scaffolding
that lays the concrete in sections. Read more.
(c) Building
High-Tech, Low-Cost Tunnels
New technology
has dramatically reduced the cost—and disruption—of building tunnels under busy
cities for rail, road and utility projects. Read more.
(d) Spun Concrete
In its continuing effort to
improve resiliency and reliability, the Tullahoma Utilities Board (TUB) is
replacing a series of wooden utility poles along Atlantic Street with spun-cast
concrete poles. Read more.
(e) Repairing
Earthquake-Damaged Bridge Columns in Days
Pantelides' quicker and more cost-effective process involves creating
concrete donuts known as "repairs" that are lined with a composite
fiber material built around the bottom and top of each column. Read more.
(f) Ground Penetrating Radar for Concrete
Ground-penetrating radar can find obstructions
under concrete without destroying it. Read more.
(g) New Concrete Pavers
This article looks at
"smart" slipform pavers, which can reduce construction time and
increase efficiency. Read more.
(h) Recycled Concrete for
Highway Resurfacing
A joint venture between
Parsons Corp. and Coffman Specialties is at work on a $120 million highway
resurfacing project in California's Cajon Pass. Workers broke up about 150,000
cubic yards of roadway, crushed it on-site and used the aggregate in lean concrete.
Read more.
(i) Ultra-Strong Concrete
New York-based Ferrara Bros.
is using a newly developed, super-strong concrete formula for the 432 Park Avenueand 55 Hudson
Yards towers in New York City. The ultra-hard concrete mix is made with
chemicals and can stay wet for up to 12 hours to aid in transportation. The
product hardens white, is weather-resistant and is 20% lighter than a
traditional mix, which allowed Ferrara Bros. to cut the number of support
columns at 55 Hudson Yards. Read more.
(j) Lightweight, Strong Concrete
Aside
from the weight, are that it is a cost-efficient building material that
combines both superior sound and thermal insulating properties along with a
one-hour per inch fire rating. Read more.
(k) The World's Longest and Deepest Rail
Tunnel
The
57.1-km (35.5 mile)-long Gotthard Base Tunnel, 17 years under construction and
designed to last a century, is part of a 23 billion Swiss franc infrastructure
project to speed passengers and cargo by rail under the mountain chain that
divides Europe's north and south. Read more.
(l) Solar Roads
Shatter-resistant,
glass-coated solar panels embedded in the pavement of a bike path in the
Netherlands can support 12-ton trucks -- and produce 3,000 kilowatt hours of
electricity. 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 224.1R-07: Causes, Evaluation, and Repair
of Cracks in Concrete Structures
The causes of cracks in concrete structures are summarized.
The procedures used to evaluate cracking in concrete and the principal
techniques for the repair of cracks are presented. The key methods of crack
repair are discussed, and guidance is provided for their proper application. Read more.
(c) PCA Publication: Design
and Control of Concrete Mixtures
The 16th edition provides a concise, current reference
on concrete, including the many advances that occurred since the last edition.
Besides presenting a 30 percent increase in new information, this edition has
new chapters on concrete pavements and structures illustrating where concrete
meets the needs of modern society. 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. They are classified
into 12 groups: air-entraining; normal, mid- and high-range water-reducing;
accelerating; set-retarding; extended set-control; workability-retaining;
viscosity- and rheology-modifying, shrinkage-reducing and
shrinkage-compensating, and corrosion-inhibiting; lithium admixtures to reduce
deleterious alkali-silica reaction; permeability-reducing; and miscellaneous.
Read more.
(e) ACI 308R-16 Guide to External Curing of
Concrete
This
guide reviews and describes practices, procedures, materials, and monitoring
methods for the external curing of concrete and provides guidance for
specifying curing procedures. Current curing techniques are presented and
commonly accepted methods, procedures, and materials are described. Methods are
given for curing structures and buildings, pavements and other slabs-on-ground,
and for mass concrete. Curing methods for several specific categories of
cement-based products are discussed in this document. Read more.
(f) ACI 506R-16
Guide to Shotcrete
This guide is a companion document to ACI 506.2,
“Specification for Shotcrete,” and provides information on materials and
properties of both dry-mix and wet-mix shotcrete. Read more.
