The present invention relates to a cured product manufacturing apparatus using industrial byproducts, and more particularly, to an apparatus for producing a cured product capable of replacing cement by uniformly mixing an industrial byproduct and an alkali activating solution in the shortest time.

Conventional cured products are manufactured by mixing powdered curing materials such as cement with water to form mortar, concrete or sometimes adding a concrete admixture for concrete such as fly ash, blast furnace slag powder and silica fume to cement.

The cement has strong alkalinity, and the strong alkali of such cement keeps the strong reinforced concrete structure by preventing the corrosion of the rebar. However, carbon dioxide in the atmosphere reacts with calcium hydroxide in the cement to turn into calcium carbonate, which is connected to the neutralization of the cement, causing severe cracks in the structure due to corrosion and expansion of the steel. Alkali in cement is an important property, but when a secondary product made of cement is used in a waterfront space, the strong alkali component of pH 12-13 is eluted in the cement, which has a serious adverse effect on the ecological environment. Reinforced concrete products that are in contact with waterside space using cement are mainly used as secondary products. Typical products are reinforced concrete plume and bench plume, revetment block, masonry retaining wall block, It is produced in the form of portland cement, so that environmental problems such as leaching of the strong alkali component are remarkable.
