Lecture

Assessing Clay Reactivity: The R3 Test

Description

This lecture covers the R3 test, a method to assess clay reactivity for making LC3. It includes the benchmark test of calcined clay strength, the influence of calcined kaolinite content on compressive strength, and the monitoring of pozzolanic reactivity. The mix design, settings for isothermal calorimetry experiments, sample preparation, and the R3 protocol for heat of hydration and chemically bound water are discussed. The lecture concludes with good correlations between the R3 test results and compressive strength tests.
