Conflict Prevention, De-escalation, and Resolution Training

All people experience conflict. From inner conflicts (“Should I confront this person?”), to interpersonal conflicts (“You’re not listening to me!”), and group conflicts (“We can’t work with those people.”), disagreements are part of the human experience we cannot change. What we can change, is how we prepare for conflicts and respond when they occur. This 2-hour, hands-on training course will teach participants skills to assist them with managing conflict over three broad stages of conflict: before, during, and after.

Interactive Cement Quality Round Table Discussion

PCA is pleased to sponsor an interactive cement quality round table discussion, the workshop is limited to the first 60 participants and will tackle some of the most critical issues in cement manufacturing. Participants will divide into four groups: four speakers, four seminars, but one workshop. Industry experts will then lead discussions speaking to each group  in a round-robin fashion. The workshop will conclude with a summary of “lessons learned” with the four groups convening together for a final wrap-up.

Below is a summary of the four seminars included in this workshop

The costs of over-burning

Free lime content directly impacts cement properties and is a critical measure for overall clinker properties. Excessive free lime indicates unreacted clinker; low or no free lime is a glaring indication of overburning. Minimizing free lime is not the same as optimizing free lime. Overburning impacts clinker chemistry and fuel efficiency. This portion of the round table discussion gives operators an overview of the causes of free lime and practical approaches to avoid over-burning by optimizing free lime contents.

How to Read a Mill Test Report

Mill test reports are more than just a summary of physical and chemical properties. They’re vital data points that customers often used to gage product consistency and to correlate composition to properties. All too often though, they’re misread, misunderstood, and misused. This portion of the round table discussion takes a deep dive into understanding the information on a mill test report: what it says, what it means, and how to effectively use it.

The Importance of Kiln Feed Consistency

The primary barrier to a quality product is variability. Reducing variability increases consistency and provides process certainty and understanding the sources of variability is the first step. This workshop investigates each source of raw materials variability driving the pyroprocess. A consistent kiln feed uniformity is a must for a consistent clinker chemistry and a consistent clinker chemistry is the best technique for stable kiln operations. This portion of the round table discussion investigates proven methods to reducing variability in each step of the entire processing chain, from quarry to cooler, from crushing to finish grinding.

Cement Quality Parameters

How do I relate clinker chemistry to cement characteristics? How do I determine the impacts of cement characteristics on the quality of concrete? By setting time, heat of hydration? Soundness? Durability? Which characteristic causes which performance effect? This portion of the “Round Table Discussion” will discuss the ways that cement composition (from alite and belite and gypsum to blaine) will impact its properties and how to balance composition to produce a consistent product.
