摘要： A method for producing calcined clay having desired colour characteristics. The method includes: a step of calcining a clay in a calcination furnace, the calcination step being carried out under stoichiometric or oxidising conditions, and a step of reducing iron (III) oxides present in the calcined clay in a reduction system separate from the calcination furnace, this reduction step being carried out by injecting a reduction gas, containing hydrogen atoms and placed in direct contact with the calcined clay.

摘要： Systems and methods for beneficiating a recovered fly ash material and/or recovering fly ash from an impound site are described. The method may include thermally treating a first portion of a recovered fly ash material to form a thermally treated fly ash having a first temperature of at least 1000° F., and contacting the thermally treated fly ash with a second portion of the recovered fly ash material to cool the thermally treated fly ash to a second temperature of less than or equal to 500° F. and form a fly ash product. The fly ash product may have a carbon content less than 8% by weight, based on the total dry weight of the fly ash product.

摘要： Methods for increasing the hardness of aggregate include applying a hardener to the aggregate. The hardener may react with a material of the aggregate and/or a material on a surface of the aggregate. For example, an alkali metal silicate, such as lithium polysilicate, or a colloidal silica may chemically react with calcium oxide and/or calcium hydroxide of an aggregate or on an aggregate to create cementitious material, which may at least partially fill pores in the surface of the aggregate, harden an existing microtexture of the aggregate and/or enhance the microtexture of the aggregate. These characteristics may enhance frictional characteristics, the wear characteristics and the durability of the aggregate, and of any structures formed from composite materials that include the aggregate.
