The group found a much cheaper substitute in coke breeze.

Coke breeze is the leftover material that is too small for the steel industry.

Coke breeze and foundry coke are included in this category.

Previous to 1999, coke breeze was discarded in the process and was not re-usable.

This fill was in the form of "coke breeze", a light weight material that was easily compacted.

These used dust-coal or coke breeze instead of coal and the manufacturers suggested they be tried out at Papplewick.

This heading also includes coke, coke breeze and semi-coke made from lignite/brown coal.

With coke breeze, the lab was able to create a conductive concrete that is only two to three times more expensive than ready-mix concrete.

Coke breeze consists of dust from the coke briquette, which is purely coke (carbon).

Coke breeze offers a backfill solution since it can be compacted to 95% and offers the best conductivity at moisture levels.

The coke breeze (undersize coke) from the crushing and screening operation is either recycled to the coke ovens or sold.

Or. Government-sponsored testing of various backfill-grounding materials shows "coke breeze" as the number-one choice based on the conductivity as well as the cost.

The main kinds of products are blast-furnace coke, foundry coke, coke nut and coke breeze.

A mixture of iron-bearing materials, limestone and coke breeze ignited and fused into a porous strong material product (sinter) suitable for charging to the blast furnace.

URR’s Duquesne Wharf, situated on the Monongahela River near Pittsburgh, is a major transfer point for bulk commodities such as coal, coke breeze, and iron ore.

Included with these materials to be assayed are non-lead bearing additives such as coke breeze and scrap iron borings which are required in the smelting and refining operations.

Presently the main products are pig iron and LAM coke along with nut coke, coke breeze, crude tar, ammonium sulphate and granulated slag (phase - I).

The oversize coke is returned to the crusher while the undersize coke, known as coke breeze, is recycled to the coke ovens, used as fuel in a sinter plant, or sold.

Atmospheric emissions also include volatile organic compounds (VOCs) formed from volatile material in the coke breeze, oily mill scale, etc., and dioxins and furans, formed from organic material under certain operating conditions.

In the sinter plant, the iron bearing material mixed with coke breeze or coal and limestone or dolomite is spread on a continuous travelling grate (sinter strand) where combustion air is drawn in, and the mixture is ignited by natural gas or fuel oil.

Initial works were delayed by heavy rain for three weeks converting the ground to a quagmire, and as a result thousands of feet of ashes and coke breeze were carted from the gasworks and deposited in order to keep trucks moving with borrow material from Nudgee.
