Research News: AMERICAN CONCRETE INSTITUTE LAUNCHES NEW SEMINAR SERIES

The American Concrete Institute announces the launch of a series of seminars hosted at ACI Headquarters in Farmington Hills, MI, USA, that will enable concrete industry professionals to receive valuable information on a variety of topics.

The seminars will allow attendees to earn PDHs/CEUs, an increasing requirement to retain PE status. Highly recognized speakers will offer face-to-face interaction, and free resources and referencing tools will be distributed for use both during and after the seminar.

The first seminar, “ACI 562: Assessment, Repair, and Rehabilitation of Existing Concrete Structures,” will be held October 30, 2018. The one-day seminar will help attendees learn how to use the ACI 562 code; learn about a design-basis code; and understand the different load combinations and reduction factors in ACI 562.

Future public seminar topics include concrete slabs-on-ground, troubleshooting concrete construction, and troubleshooting concrete forming and shoring. The seminars will be held at ACI Headquarters, in Farmington Hills, MI, USA.

Research News: SMART CEMENT TO TURN BUILDINGS INTO BATTERIES

Researchers at Lancaster University have developed a fly ash and alkaline solution cement mixture that is capable of conducting and storing electricity. The mixture, a potassium-geopolymeric (KPG) composite, conducts electricity through potassium ions that pass through the crystalline structure. The mixture can store and discharge between 200 to 500 watts per square meter.

The mixture can also be used to sense mechanical stress on structures caused by cracks, which alter its conductivity. When measuring the changes in the way potassium ions move, the structural health of a building can be detected automatically without additional sensor installation. Researchers are carrying out further work to optimize the performance of the KPG mixture and explore the incorporation of 3-D printing techniques.

Research News: PURDUE RESEARCHER ADVANCING CONSTRUCTION THROUGH AI

A robotic system that installs rebar for concrete and software that compares a building's design to local building codes are among the advances in the construction field at Purdue University. "We've developed new technology in our domain to help with productivity, safety, quality and cost of the products," construction management technology professor Jiansong Zhang says.

Artificial intelligence is a major part of technology in future construction, including the early stages of planning. In his lab, Zhang works on software side with the algorithms of computing technology, which are used to support future automation on the job site.
