What is 6F5 used for?

What is 6F5 used for?

Uses: Capping layer for larger road and highway construction, civil engineering, driveways, landscaping, pathways and as a general fill material.

What is the difference between 6F2 and 6F5?

6F5 is an unbound, coarse recycled aggregate made from crushed hardcore and concrete and graded from 75mm down to dust. 6F2 can be used as bulk fill to build up levels, as a temporary hard standing, for firming up soft or wet ground or for use as a layer below Type 1 crushed/primary.

What is 6F1 aggregate?

6F1 – Again this is a very good general purpose aggregate and often used on top of the 6f2 as this is a fine material of 45mm down. Perfect to compact into any small areas and still create a hard wearing surface. This is often used as a substitute for primary type 1.

Why is it called 6F5?

The term 6F5 Capping is generally used to describe a product that is similar in size and grading to recycled 6F2 Crusher Run but made from quarried stone instead.

What size is 6F5 stone?

What is the difference between 6F2 vs 6F5?

What is IBA aggregate?

IBA Aggregate is a sustainable and accepted alternative to Type 1, 6F4 and 6F5 capping and consists of fused clinker, ceramics, glass, stone and concrete. It has been widely used in construction for over 20 years and has been approved by the Environment Agency, Highways England and local authorities with great success.

Which aggregate is best for slab?

Gravel
Gravel or broken stone aggregates with rough and non-glassy texture are the best aggregates because they create a good bond with the cement paste. Aggregates need to be hard, strong, chemically inert, and non-porous. Organic substances and dirt coating compromise the strength and durability of concrete.

Can crushed concrete be used as sub-base?

Oversized Crushed Concrete Used mainly as a sub-base or drainage layer, this is a cost effective alternative to primary limestone or granite when laying down haul roads, building paths or patio sub-bases, or drainage layers. Oversized crushed concrete is also perfect for wet conditions on site.

What is 6F3 aggregate?

Class 6F3 is selected granular material that can contain any amount of granulated asphalt and recycled bituminous planings. This class excludes any material which contains tar or tar-bitumen binders. Class 6F4 is generally evenly graded material of sizes ranging from 50mm diameter to dust.

Is 6F2 a waste?

We are regularly asked by our customers to remove or relocate 6F2 from their sites which has been used for temporary works. The material is then technically deemed a waste product.

Is 6F2 a Type 2?

Usage: 6F2 stone or type 2 crushed concrete is the by-product of demolition and is an inexpensive, coarse aggregate that can be used as a well-draining sub-base for various projects, including roads, pathways, patios, driveways and buildings.

What is IBA recycling?

Recycling information Incinerator bottom ash, also known as IBA, is a by-product of residual waste incineration with or without energy recovery that collects at the bottom of municipal incinerators.

What is ash waste?

Incinerator bottom ash (IBA) is a form of ash produced in incineration facilities. This material is discharged from the moving grate of municipal solid waste incinerators. Once IBA is processed by removing contaminants, it can be used as an aggregate.

What is 6F5 aggregate made of?

6F5 is an unbound, coarse recycled aggregate made from crushed hardcore and concrete and graded from 75mm down to dust. 6F2 can be used as bulk fill to build up levels, as a temporary hard standing, for firming up soft or wet ground or for use as a layer below Type 1 crushed/primary.

What is aggregate in concrete?

Aggregate may be natural, manufactured or recycled. It includes gravel, crushed stone, sand, slag, recycled concrete and geosynthetic aggregates. For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete.

What makes a good concrete mix?

For a good concrete mix, aggregates need to be clean, hard, strong particles free of absorbed chemicals or coatings of clay and other fine materials that could cause the deterioration of concrete. At the most general level, aggregates come in two varieties:

What are fine aggregates?

Fine Aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. When the aggregate is sieved through 4.75mm sieve, the aggregate passed through it. Natural sand is generally used as fine aggregate, silt, stone dust and clay also come under this category.
