Question

For estimating the water absorption of aggregate used for concrete, the prescribed oven drying temperature (degree C) is:

120 – 130

90 – 100

110 – 120

100 – 110

Solution

Correct option is D

This test helps to determine the water absorption of coarse aggregates as per IS: 2386 (Part III) – 1963. For this test, a sample not less than 2000g should be used.
The aggregate is placed in a shallow tray and heated to 100 to 110°C in the oven for 24 ± 0.5 hours.
