SGS TEC Services is an AASHTO R18, ANS/ISO/IEC 17025:2017, and is an Army Corps of Engineers
|
||
|
||
accredited laboratory. 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.

moisture content, and the volume of the concrete batch. The calculated equilibrium density of 113.7 lb/ft³
|
||
|
||
was calculated by adding 3 lb/ft³ to the calculated oven-dry density. The calculated equilibrium density is
|

|
||
|
||
Requirement – For concrete with combinations of normal weight and lightweight aggregates and a

calculated equilibrium density of 113.7 lb/ft3, the minimum compressive strength is 3,740 psi. This was
|
||
|

Splitting Tensile Strength of Cylindrical Concrete Specimens.
|
||
|
||
Requirement – For a concrete with combinations of normal weight and lightweight aggregates and a

Change of Hardened Hydraulic-Cement Mortar and Concrete and modified per ASTM C330. Three
|
||
|

length change beams (4” x 4” x 11¼”) were moist cured for seven days. Upon the completion of the 7-
|
||
|
||
day moist curing an initial reading was obtained, which was used as the base length for the drying
|
||
|
||
shrinkage calculations. The samples were then placed in a curing cabinet maintained at 100 ± 2°F with a
|
||
|
||
relative humidity of 32 ± 2% for 28 days.
|
||
|
||
Requirement – The drying shrinkage of the concrete specimens shall not exceed 0.07% at 28days.
