Abstract:
The present invention relates to a concrete composition for building materials including waste glass and blast furnace slag micropowder, and a method for manufacturing building materials using the same. More particularly, the present invention provides a concrete composition for building materials including blast furnace slag micropowder and a method for manufacturing for building materials using the same, wherein the composition comprises cement, waste glass, blast furnace slag micropowder, a thickener and a superplasticizer, and specifically, for 100 parts by weight of cement, the composition includes 80-120 parts by weight of blast furnace slag micropowder, 600-850 parts by weight of waste glass, 0.3-1 parts by weight of the thickener and 0.3-1 parts by weight of the superplasticizer. As the concrete composition for building materials according to the present invention comprises blast furnace slag micropowder, waste glass, cement, the thickener and the superplasticizer at an optimal mixing rate, the composition has effects of being capable of manufacturing building materials which are cheaper and thinner and higher resistance to cracking in comparison with the existing concrete compositions including waste glass and blast furnace slag micropowder. In addition, as it comprises the thickener and the superplasticizer at an optimal mixing rate, the building materials manufactured through the concrete composition such as a concrete panel and the like have advantages of not generating dust and having remarkable adhesive power and surface gloss so as to be able to replace expensive building materials. Furthermore, the building materials manufactured from the concrete composition have excellent regeneration properties, and therefore, the building materials can be recycled after being destroyed so as to have remarkable economic feasibility, and have advantages of being capable of being used as interior and exterior building materials.
