A method is provided for use of a concrete composition and an associated apparatus. The method provides for mixing of the concrete material, accelerant powder and, optionally, an associated substance to enable the controlled hardening of the concrete material in a monolithic structure. The apparatus can dispose a slip-plane film to facilitate a relatively continuous process.

Method, composition and apparatus for controlled concrete

A high temperature hot strength magnesia-based refractory composition having high durability at elevated temperatures wherein a sulfamic acid in combination with an independent calcia source is added to a magnesia-based refractory material. The invention also provides for a refractory gunning composition for use in the production or repair of metallurgical furnace linings.
