掺陈化粮对烧结多孔材料性能的影响

利用陈化粮作为成孔剂制备轻质高强高孔洞率的烧结墙体材料，系统研究了成孔剂掺量和粒径对烧结制品性能的影响。结果表明：在相同烧成制度下，掺加试样质量比15%的0.15 mm~0.3 mm陈化米粒径的试件体积密度降低为1.35 g/cm3，气孔率达到45.89%，制品气孔率提高了83%，抗压强度为18.56 MPa；随着气孔率的增大，抗压强度降低，当气孔率大于35%时，成孔剂的粒径对抗压强度影响明显，当气孔率小于35%时，烧结制品性能相对稳定。

Effect of ageing rice as porosification agent on the performance of fired perforated material

The paper researches the effect of addition amount and particle size of ageing rice as porosification agent on the performance of fired material.The result shows that when sample contains 15%（in mass） of 0.15~0.3 mm rice, the bulk density decreases to 1.35 g/cm3, the compressive strength is 18.56MPa and the porosity is 45.89 % which increases 83 % than 100 % shale products in the same sintering system; As the porosity increases, the compressive strength decreases. When the porosity is beyond 35%, the particle size of ageing rice have a strong influence on compressive strength;when the porosity is below 35%, the performance of the fired product is relatively stable.
