The Role of Aggregate in Concrete - The Concrete Network

Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.

CE Center - Specifying Sustainable Concrete

Crushed returned concrete can be used as a portion of the aggregate in concrete for some applications to conserve materials and minimize waste. The use of recycled material can contribute to credits in green construction rating systems. The use of crushed concrete as aggregate is recognized in industry standards.

Production of Lightweight Concretes from Pumice/Bentonite

This study deals with the replacement of pumice by bentonite in the production of lightweight concretes. Pumice Aggregate is highly recommended in lightweight concrete blocks either blended or as an all in a pumice mix. Expanded clay aggregate has been pelletized and fired in a rotary kiln. During firing, the organic compounds in the clay burn off, forcing the pellets to expand. The resulting

Appropriate Applications for Lightweight Concrete

A: (Kelly) Lightweight concrete is not usually used for plastering applications; it doesn't tend to be quite as durable a finish because often the aggregate is softer, or there is more air entrained in the mixture. If the mixture were adhesive enough it should stick OK, so you might add lime or even latex.

What is Green Concrete?

Green concrete is made using industrial waste materials as a partial replacement for other concrete components, like cement or aggregate, whose production takes a heavier toll on the environment. While some forms of green concrete are newer, many may not realize that other types have been in use for decades.

Aggregates for Concrete - GreenSpec - Green Building

Key points. • 'Aggregate' is a term for any particulate material. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. Aggregate may be natural, manufactured or recycled. • Aggregates make up some 60 -80% of the concrete mix. They provide compressive strength and bulk to concrete.

Classification of Aggregates: Grain Size, Density, Shape

Classification of aggregates based on: Grain Size. The size of fine aggregates is defined as 4.75mm or smaller. That is, aggregates which can be passed through a number 4 sieve, with a mesh size of 4.75mm. Fine aggregates include things such as sand, silt and clay. Crushed stone and crushed gravel might also fall under this category.
