SGS TEC Services is pleased to present this interim report of our testing on the expanded lightweight aggregate submitted to our laboratory in August of 2023. The results of this testing pertain only to the samples tested. The aggregate was tested in accordance with the applicable sections of ASTM C330-17 Standard Specification for Lightweight Aggregates for Structural Concrete. This specification covers lightweight aggregates intended for use in structural concrete in which prime considerations are reducing the density while maintaining the compressive strength of the concrete. The maximum and minimum requirements for this specification are presented in Section 5 Chemical Composition and Section 6 Physical Properties of ASTM C330 and are reported in Table 1. Based on our results to date, the 1/2 Structural lightweight aggregate labeled as Bloated Material (Russell County Reclamation) submitted to our laboratory meet and/or exceeds the requirements of ASTM C330.
