Abstract “Green cement” has been extensively studied to reduce the carbon emission and the energy consumption associated with the construction materials production. In this research, we developed a sectioned compaction system to produce bricks of ultralow-binder-content (UBC) composite, which consisted of ∼96 wt.% sand and ∼4 wt.% epoxy binder. After premixing, the material was compressed in nine sections and two steps. Upon compaction, the small amount of binder self-assembled into polymer micro-agglomerations (PMA), which efficiently bonded the sand grains into a structurally integral solid. The so-produced material was uniform and quite strong. The modulus of rupture was ∼23.5 MPa, two times higher than the typical flexural strength of steel-reinforced concrete.

超低粘合剂含量颗粒复合材料压实自组装的分段加工

摘要 “绿色水泥”已被广泛研究以减少与建筑材料生产相关的碳排放和能源消耗。在这项研究中，我们开发了一种分段压实系统来生产超低粘合剂含量 (UBC) 复合材料的砖，该复合材料由约 96 重量％的沙子和约 4 重量％的环氧粘合剂组成。预混后，将材料分为九段和两步进行压缩。压实后，少量粘合剂自组装成聚合物微团聚体（PMA），有效地将砂粒粘合成结构完整的固体。如此生产的材料均匀且相当坚固。断裂模量约为 23.5 MPa，是钢筋混凝土典型抗弯强度的两倍。
