Table 5 Data showing linear and volumetric changes of samples after heating up to 650 °C and 1000 °C. The changes were not noticeable after heating up to 300 °C. Where there is no value in the table the decrease was unnoticeable.

From: Influence of very high temperatures on properties of medium grained lightweight aggregate mortars containing perlite and various cement types
