Low-water-absorption environment-friendly high-strength ceramsite and preparation method thereof
The invention discloses low-water-absorption environment-friendly high-strength ceramsite and a preparation method thereof.The ceramsite is prepared from granite waste, granite raw ore fine silt, ardealite and phosphate tailings as raw materials through mixing granulation and two-stage roasting. The compressive strength of the obtained ceramsite is 30-40 MPa, the stacking density is 700-900 kg/m < 3 >, the 1h water absorption rate is 0.5-1.5%, and the hydrochloric acid leaching rate is 0.23-0.45%; the quality of the ceramsite is effectively improved, and the fired ceramsite is relatively high in strength and has relatively low density, water absorption rate and hydrochloric acid leaching rate.
本发明公开了一种低吸水率环保高强陶粒及其制备方法，其中，所述陶粒以花岗岩废料、花岗岩原矿细泥、磷石膏和磷尾矿为原料，混合造粒并两段焙烧制成。得到的陶粒的抗压强度为30～40MPa，堆积密度为700～900kg/m3，1h吸水率为0.5～1.5％，盐酸浸出率为0.23～0.45％；有效改善了陶粒的品质，烧制出的陶粒的强度较高，具有较低的密度、吸水率及盐酸浸出率。
