COMMANDbatch Named “Best Product in
Show” at the UK Concrete Show
Command Alkon’s COMMANDbatch was awarded the
title “Best Product in Show” at the annual UK Concrete Show
in Birmingham, England, UK. COMMANDbatch was chosen
for its ability to alert staff members when a batched material is
out of tolerance or when an operator has added too much
water to the mixture and has exceeded the maximum
allowable water-cementitious materials ratio (w/cm). With
COMMANDbatch, owners, general managers, and operations
managers can stay connected to their batch plants at any time
in any location.
Knife River Corporation Acquires Texas
MDU Resources Group, Inc., announced that subsidiary
Knife River Corporation acquired substantial additional
aggregate deposits in Texas, which will augment existing
company operations and enhance the company’s ability to sell
aggregates to third parties. Knife River Corporation mines
aggregates and markets crushed stone, sand, gravel, and
related construction materials, including ready mixed
concrete, cement, and other products. The acquired land,
purchased from Capitol Aggregates Inc., spans 570 acres
(231 ha) and sits near Marble Falls, TX. The property has
access to a major rail line, and Knife River anticipates adding
a rail loading facility to the site to transport aggregates to
existing company locations in Waco, Bryan, and Beaumont, TX,
as well as to third parties.
Petuum Industrial AI Delivers Supervised
Autonomous Cement Plant Operations for
Petuum and CEMEX entered into a global agreement
under which CEMEX can implement Petuum Industrial AI
Autopilot products with autosteer in all cement plants
worldwide for autonomous cement plant operations. AI
Autopilot is being deployed at select CEMEX USA and
CEMEX Mexico plants and will continue to be rolled out
Petuum Industrial AI Autopilot products offer real-time
forecasts for key process variables, prescriptions for critical
control variables, and supervised autosteer for all cement
plant operations. This includes clinker cooler, preheater, rotary
kiln, pyro process, ball mill, and vertical mill processes.
Plants using AI Autopilot can reduce energy consumption and
increase throughput while maintaining stable operation and
high product quality.
The joint CEMEX and Petuum teams achieved a
supervised “autosteer mode” resembling cruise control, in
which the AI Autopilot runs operations with full engage/
disengage control available to an operator. CEMEX and
Petuum will continue collaborating to deploy additional
Autopilot use-cases for global cement plants, including
emissions reduction, fuel-mix (alternative fuel) optimization,
and preventive maintenance.
150 North Riverside Project Wins ASCE’s
Outstanding Civil Engineering Achievement
The American Society of Civil Engineers (ASCE)
recognized the structural engineering design of 150 North
Riverside, Chicago, IL, by awarding the project the
Outstanding Civil Engineering Achievement Award.
Magnusson Klemencic Associates, Inc., accepted the award
on behalf of the entire design and construction team.
The building’s design is noteworthy in that it features a
razor-thin concrete core that makes its small footprint
possible. The core, which is three times skinnier than that of a
typical office building, was created using twin, balancing,
four-story tall brackets on two sides of the building, reducing
the building’s base footprint by 80%. Eight massive steel
transfer systems with top-level tension ties and lower-level
compression struts were used to redirect the loads from the
exterior columns, allowing for the tapered lines and elegant
slope of the building.
The design includes the first use of a water tank damper on
a thin-core building. Twelve water-filled tanks (160,000 gal.
606,000 L) on top of the tower minimize wind sway
through wave action. In
addition, the 16 sloping
columns at the brackets
comprise the largest rolled
steel sections in use in a
high-rise building within
the United States.
The building’s notable
design was developed to
provide the community with
a vibrant public space on a
narrow site. A new 1.5 acre
(0.6 ha) public park, a
pedestrian pathways, and
retail venues offer refuge
from the city’s bustle.
