摘要
现有建筑填充材料主要通过烧结、蒸压、水化等工艺制成,整个生命周期消耗能源、污染环境、难以降解,由菌丝复合生成的填充类材料可替代现有建筑填充材料。基于此对新型建筑含菌复合材料的塑造试验进行了设计、筛选、测试、分析,比选出真菌类生物复合材料的成型试验方案。试验表明,试件变形量为10%时,培养期在2、3周时的试件抗压强度分别可达到0.73、1.69 MPa;试件尺寸为5 cm立方体比7 cm立方体强度提高了30%~50%,透气性可明显提高菌丝生长和试件强度;增加材料的含砂量可提高试件强度,但过高的含砂量反而降低了掺合料之间的黏聚力,使其强度降低。
The existing building filling materials are mainly made by sintering,autoclave,hydration and other processes.The whole life cycle consumes energy,pollutes the environment,and is difficult to degrade.The filling materials generated by the mycelium composite can replace the existing building filling materials.Based on this,the molding test of the new building composite material containing fungi was designed,screened,tested and analyzed,and the molding test scheme of the fungal biological composite material was selected.The test shows that when the deformation of the specimen is 10%,the compressive strength of the specimen at 2 weeks and 3 weeks can reach 0.73 MPa and 1.69 MPa respectively.The strength of the 5 cm cube is 30%~50%higher than that of the 7 cm cube,and the permeability can significantly improve the mycelial growth and the strength of the specimen.Increasing the sand content of the material can improve the strength of the specimen,but too high sand content reduces the cohesion between the admixtures and reduces its strength.
