A method of applying a refractory castable material to the surface of a structure comprising the steps of thoroughly mixing a refractory castable material comprised primarily of aggregate and a cementitious binder; conveying the refractory material under pressure through a delivery hose to a dispensing nozzle; and adding hydrated lime to the refractory castable material prior to application by ...
and mechanical properties of refractory concrete after exposure to high temperatures. A complex binder together with firestone aggregates was used for production of refractory concrete, which was reinforced simultaneously with micro fibre (1 wt % and 3 wt %) and micro silica (1.5 wt %, 3.5 wt % and 5 wt %). Unmodified concrete was produced as well.
Various types of concrete have been developed for specialist application and have become known by these names. Concrete mixes can also be designed using software programs. Such software provides the user an opportunity to select their preferred method of mix design and enter the material data to arrive at proper mix designs.

There is no evidence that the mixtures have refractory capabilities and meet the definition of refractory found in Additional U.S. Note 2 to Chapter 69, HTSUS (see HQ 956145 dated July 29, 1994, applying that definition of refractory to Chapter 38, HTSUS). Therefore, for purposes of this ruling, we assume the products to be nonrefractory.
Refractory monolithic compositions or ingredients: It consists of refractory aggregates, or refractory sand, refractory powers, binders, additives, and water at certain proportion. Aggregate is the skeleton and power fills the cracks and reacts with binder thus improves the strength or other properties.
