| 中文摘要: |
| 利用体积法计算出不同干密度聚丙烯纤维增强泡沫混凝土的配合比，制备出聚丙烯纤维增强泡沫混凝土。研究不同等级干密度对其力学性能、保温性能和干燥收缩性能的影响，并在良好保温性能、强度与较低干收缩条件下，探讨聚丙烯纤维增强泡沫混凝土的最优干密度。结果表明：干密度等级越高的聚丙烯增强泡沫混凝土力学性能好，干燥收缩值变化较小，但其导热系数较大，保温性能差。具有良好保温性能、强度与较低干收缩聚丙烯纤维增强泡沫混凝土的最优干密度为800-900 Kg/m³。 |
| 英文摘要: |
| Volume method is used to calculate the different dry density of polypropylene fiber reinforced foam concrete mixture ratio and polypropylene fiber reinforced foam concrete is prepared. This paper studies the influence that different dry density has on mechanical property, heat-insulating property and dry shrinkage performance；and then this paper investigates the optimum dry density of polypropylene fiber reinforced foam concrete under the condition of good thermal insulation performance, strength and low dry shrinkage. Results show that polypropylene fiber foamed concrete of higher dry density bears better mechanics performance and smaller drying shrinkage value, but with larger thermal conductivity, heat preservation performance is poor. As to olypropylene fiber reinforced foam concrete of good thermal insulation performance，and low dry shrinkage , the
optimum dry density is 800-900 Kg/m³. |
