The density of the bulk samples, as received, is calculated as follows: Volume of the prepared sample = 𝑉 Mass of the prepared sample = 𝑀 𝑀 𝜌 = bulk 𝑉 The water content of the sample is calculated as follows: Mass of the sample after testing (initial mass before drying) = 𝑀𝑖𝑛𝑖𝑡 Mass of the sample after drying = 𝑀𝑑𝑟𝑦 𝑀𝑖𝑛𝑖𝑡 − 𝑀𝑑𝑟𝑦 𝑤 = 𝑀𝑑𝑟𝑦 Calculation of the sample dry de. [...] The solution to the thermal conductivity equation assumes the sensor is in an infinite medium, so the measurement and subsequent analysis of data must account for the limitation created by the outer boundaries of the material. [...] Recording of the acoustic emissions may not start at the same time as the recording of the strains; therefore, the two records (strains and AE) are time-matched at the peak stress in order to compare the time (and stress) of the crack initiation process. [...] Note that the sample depths in the graph legends refer to the depth of the original sample as collected (part of the id), not the depth of the sub-samples. [...] The coefficient of linear thermal expansion was calculated from thermal strain vs temperature data points by two methods: 1) as the slope of the linear regression line through the data points and 2) fitting a second order polynomial to the same data and deriving the slope of the polynomial at the target temperatures.
