A related approach is the use of mineral carbonation (MC) to produce stable carbonate aggregates from calcium- or magnesium-containing materials and CO 2. Stable aggregates can be used in concrete production or to produce carbon neutral building blocks such as bricks or precast concrete.

Refractory Aggregate. Refractory aggregate is a kind of refractory granular material which plays a skeleton role in the granularity composition of refractories. They are granular materials with particle size greater than 0.088mm, which are made from various raw materials of charge fire by calcination, crushing or artificial synthesis.
Aggregates are the backbone of a refractory formulation and provide dimensional stability to the refractory products. The coarser fractions add thermal shock and corrosion resistance and the aggregate fines optimize the particle size distribution and increase the refractoriness of the product.

A refractory material or refractory is a heat-resistant material: that is, a mineral that is resistant to decomposition by heat, pressure, or chemical attack, most commonly applied to a mineral that retains strength and form at high temperatures..
Refractory removal is done in many industries at regular intervals for maintenance and repair. The petrochemical industry regularly schedules turnaround in their plants and facilities which allows for a thorough inspection of vessels, pipes, equipment, etc. Plants with kilns, boilers, furnaces, hydrocrackers, and incinerators many times need to remove the refractory linings during turnaround.

Refractory Concrete, consisted of aggregate, binder and admixture is a kind of special concrete.This kind of refractory concrete is cheap and is easy to make complex shape of other products. Refractory concrete is commonly used for lining, furnace door,furnace wall and electric furnace.
3-5mm Calcined Bauxite Aggregate For Castable Refractory. Calcined bauxite is an artificial aggregate with higher strength and hardness than natural bauxite.It is an indispensable material in making refractory castable.Mixed with high alumina cement, powder according to a certain of proportion, high alumina aggregates can be made into refractory concrete with high strength.
The refractory and thermal properties of these castables are governed by the type of cement used (40–80 per cent alumina) and the aggregates (Table 13.14). These products have been in use for many decades and were, until the 1980s, the only type of hydraulically bound refractory castable in use.

However, the behaviour of the concretes with aggregates of mullite chamotte (M-P-F) and tabular alumina (T-P-F) was not the expected one for a refractory material, although these aggregates were denser and much less porous than the cordierite-mullite aggregate and they required 10% less of water in the preparation.
