By |  March 5, 2020

Logo: ConExpo-Con/Agg 2020Aggregate producers who attend ConExpo-Con/Agg 2020 have up to 13 aggregate-specific education sessions they can attend.

A variety of speakers will offer best practices related to aggregate processing, community relations, finance and other areas fundamental to the quarry business. Most sessions will take place at the Westgate, which is adjacent to the Las Vegas Convention Center. Here is an overview of the aggregate-specific sessions available.


TUESDAY, MARCH 10

9:30 a.m. – 10:30 a.m.

Drill & Blast Improvement Project Using Photogrammetry, GPS & Drill Navigation Systems

David Stewart, CRH, and Tamara Whitaker, R.A. McClure
Westgate (Pavilion 10)

This session presents a case study of the Warren County Quarry in Camak, Georgia, where initial blasting generated high percentages of oversize, back break, poor floor control and poor fragmentation. Through implementing a proactive drill and blast design and technology like automated borehole logs, 3-D photogrammetry, blast design software, angle borehole drilling, an unmanned aerial system, and geological analysis, the quarry realized significant measurable improvement. Those who attend this session can expect to:

1. Learn how a drill and blast optimization program can improve primary throughput

2. Know how to reduce secondary breakage and fines

3. Understand how to improve efficiencies with loading and hauling of shot rock

1:00 p.m. – 2:30 p.m.

Concrete Mix Design: What To Look For

Ken Hover, Cornell University
South Hall (S232)

Concrete Mix Design can be as simple as the time-honored 1:2:3 blend of cement, sand and stone. Or, it can be as complicated as one, two, three or four cementitious materials and up to five aggregate bins. But there are a few fundamental principles that apply to all concrete mixes, and understanding those principles can help you troubleshoot, modify or adjust a mix to produce the results needed. Those who attend this session can expect to:

1. Understand why water control is so essential

2. Know what to look for in aggregate size, shape and textures

3. Recognize the advantages and disadvantages of supplementary cementitious materials and admixtures.

Be Prepared: Protect Your Operation from New Tactics in Community Opposition

David Perkins, Texas Aggregates & Concrete Association
Westgate (Pavilion 10)

Your company probably already has a community relations program in place to positively engage with your operation’s surrounding community and address neighbors’ concerns. But do you have a plan to mitigate today’s tech savvy and engaged activist? Today’s opposition is comprised of well-connected people who utilize social media, word of mouth and scientific data to bolster their position and make our industry look bad.

This panel discussion will look at new ways community organizers are targeting aggregate operations, spreading misinformation and attempting to harness opposition in order to disrupt or block operations. Attendees will learn what to look for and gain tips on how to proactively respond in a way that presents an operation as a good neighbor and an asset to the community.
