NONCEMENT FLOORING COATING MORTAR COMPOSITE FOR REVEALING EARLY STRENGTH

摘要

The present invention relates to a cement-free flooring finishing mortar composition of early strength development type. More particularly, according to the invention, the portland cement is not used as a binder at all but high calcium of fly ash, fine powder of blast furnace slag and refined fly ash, a hydration accelerator, which includes a composite calcium aluminate-based inorganic material synthesizing cokes ash, paper sludge incineration ash and aluminum dross residue, is mixed with fatty acid of an organic material to improve a construction condition of mortar, thus an early strength development is possible, a sinter shrinkage of mortar derived shrinkage reducing properties of a calcium aluminate-based compound and a dry shrinkage crack occurrence can be reduced, and also, all kinds of industrial byproducts can be recycled by using every material.
