Manufacturing method of building material using stone waste
The present invention relates to a manufacturing method of a building material using stone waste. The manufacturing method of a building material using stone waste manufactures civil engineering and building materials such as bricks, sidewalk blocks, kerbs, retaining wall blocks, flagstones, etc. by recycling stone waste to be eco-friendly without harmful substances, improve strength and durability, and reduce costs. The manufacturing method of a building material using stone waste comprises: a first step (S10) of blending 80 to 85 parts by weight of stone sludge powder, 10 to 15 parts by weight of silicon dioxide (SiO2), and 5 to 10 parts by weight of potassium silicate (K2SiO3) to manufacture a primary raw material mixture; a second step (S20) of firstly firing the primary raw material mixture manufactured in the first step at a predetermined temperature; a third step (S30) of pulverizing the primary raw material mixture fired through the second step to a predetermined size; a fourth step (S40) of blending 80 parts by weight of the pulverized primary raw material mixture, 20 parts by weight of an additive, and 10 to 20 parts by weight of water to manufacture a secondary raw material mixture; a fifth step (S50) of forming a block member by placing the secondary raw material mixture in a building material mold and performing thermo-compression bonding; a sixth step (S60) of drying the molded block member at a predetermined temperature and a time; and a seventh step (S70) of forming a building material by secondarily firing the block member dried through the sixth step at a predetermined temperature.
본 발명은 석재 폐기물을 재활용하여 벽돌, 보도블록, 보차도경계석, 옹벽블록, 판석 등과 같은 토목 및 건축 자재를 제조하되, 유해성분이 없는 친환경적이며 강도와 내구성이 향상되고 원가가 절감되도록 한 석재 폐기물을 이용한 건축자재의 제조방법에 관한 것으로, 석재슬러지 분말 80~85 중량부, 규석(SiO2) 10~15 중량부 및 규산칼륨(K2SiO3) 5~10 중량부를 배합하여 1차 원료혼합물을 생성하는 제1공정(S10); 상기 제1공정에서 생성된 1차 원료혼합물을 일정한 온도로 1차 소성하는 제2공정(S20); 상기 제2공정을 통해 소성된 1차 원료혼합물을 일정한 크기로 분쇄하는 제3공정(S30); 상기 분쇄된 1차 원료혼합물 80중량부와, 첨가제 20중량부 및 물 10~20중량부를 배합하여 2차 원료혼합물을 생성하는 제4공정(S40); 상기 2차 원료혼합물을 건축자재 성형틀에 넣고 열 압착하여 블록부재를 성형하는 제5공정(S50); 상기 성형된 블록부재를 일정온도 및 시간으로 건조하는 제6공정(S60); 및 상기 제6공정을 통해 건조된 블록부재를 일정한 온도로 2차 소성하여 건축자재를 성형 완료하는 제7공정(S70)을 포함하여 된 것을 특징으로 한다.
