电解锰渣制备高掺量免烧胶凝陶粒的抗压强度研究

Study on the Compressive Strength of High-volume Non-sintering Cementitious Ceramsite Prepared from Electrolytic Manganese Slag

以电解锰渣为高掺量添加剂,探究电解锰渣添加量、水泥添加量、粉煤灰添加量、及激发剂石灰添加量对陶粒抗压强度的影响。结果表明:电解锰渣添加量为58.7%,粉煤灰添加量为29.3%,水泥添加量为12%,激发剂为NaOH添加量占电解锰渣、水泥、粉煤灰总质量的8%时,陶粒抗压强度最大为7.0 MPa。

Using electrolytic manganese slag as a high-volume additive, explore the influence of electrolytic manganese slag addition, cement addition, fly ash addition, and activator lime addition on the compressive strength of ceramsite. The results show that the addition amount of electrolytic manganese slag is 58.7 %, the addition amount of fly ash is 29.3 %, the addition amount of cement is 12 %, and the activator is NaOH when the addition amount is 8 % of the total mass of electrolysis manganese slag, cement and fly ash. The maximum compressive strength of ceramsite is 7.0 MPa.
