kolkata specific gravity of dry aggregate

Characteristics of Aggregates: Shape, Size & Specific Gravity

The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.

CIVL 1101 - Part 6 - Concrete Agregates

Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. Strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. Aggregates are classified based on specific gravity as heavyweight, normal-weight, and lightweight.

HOW AGGREGATE PROPERTIES AFFECTS CONCRETE PROPERTIES?

The concrete density is greatly depending on the specific gravity. A porous nature (i.e. those which increase in weight exceeding 10% of dry weight after immersion for 24 hours) should not be permitted, unless specified. The range of specific gravity for aggregates should be between 2.4 and 2.9. Soundness of Aggregate
