A laboratory technician performing a test on fine aggregates in accordance with ASTM C128 weighed the pycnometer filled with water reading 1201.8 g on the scale. He then took 502.3 g sample in saturated surface dry condition and poured into the pycnometer partially filled with water then filled it up to the calibrated mark. The weight of the pycnometer containing water and sample is 1516.1 g. After which he poured the content of the pycnometer in a drying pan and dried the sample in the oven. The resulting weight of the sample after drying was 494.9 g. Compute the following: a. Bulk Specific Gravity (oven dry) b. Bulk Specific Gravity (SSD) c. Apparent Specific Gravity d. Absorption in %

Question
A laboratory technician performing a test on fine aggregates in accordance with ASTM C128 weighed
the pycnometer filled with water reading 1201.8 g on the scale. He then took 502.3 g sample in
saturated surface dry condition and poured into the pycnometer partially filled with water then filled it
up to the calibrated mark. The weight of the pycnometer containing water and sample is 1516.1 g.
After which he poured the content of the pycnometer in a drying pan and dried the sample in the
oven. The resulting weight of the sample after drying was 494.9 g. Compute the following:
a. Bulk Specific Gravity (oven dry)
b. Bulk Specific Gravity (SSD)
c. Apparent Specific Gravity
d. Absorption in %
