Concrete - Wikipedia

Fine and coarse aggregates make up the bulk of a concrete mixture. Sand, natural gravel, and crushed stone are used mainly for this purpose. Recycled aggregates (from construction, demolition, and excavation waste) are increasingly used as partial replacements for natural aggregates, while a number of manufactured aggregates, including air-cooled blast furnace slag and bottom ash are also ...

Waste glass powder as partial replacement of cement for ...

As with flow, test on mortar is also carried out for compressive strength. The mass ratio of sand to (cement + glass powder) was fixed at 2.75 according to ASTM C109 (ASTM, 2016c) for all batches.

Cement Standards and Concrete Standards

ASTM cement standards and concrete standards contain specifications and test methods to determine the properties of concrete, hydraulic cements, and aggregates.

What is bulk density of cement, aggregate, sand? - Quora

* The bulk density is the mass of the material related to a specific volume and for cement is normally expressed as "kilograms per cubic metre". * The bulk density reflects the volume taken up by the cement plus any air trapped between the p...

Coarse Aggregate Specific Gravity - Pavement Interactive

The standard coarse aggregate specific gravity and absorption test is: AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate; Background. Specific gravity is a measure of a material's density (mass per unit volume) as compared to the density of water at 73.4°F (23°C).
