Abstract

The lack of suitable destinations for plastics materials can be a global environmental problem. The alternative use of materials for sustainable construction encourages the standardization of waste and promotes effective social, environmental and economic gains at the local level and ensures savings and income for communities. The aim of this paper is the development, manufacture, and characterization of PP and HDPE recycled polyolefin blocks as masonry components in civil construction. These blocks were manufactured by the rotational molding process. Besides this, the mechanical, physical, impact and flammability properties of the blocks were studied. In conclusion, HDPE showed better behavior than PP in tests realized.

摘要

塑料材料缺乏合适的归宿可能成为一个全球性环境问题。将材料用于可持续建筑的替代用途，鼓励了废物的标准化，并在地方层面促进了有效的社会、环境和经济收益，还确保了社区的节约和收入。本文的目的是开发、制造和表征作为民用建筑砌体构件的聚丙烯（PP）和高密度聚乙烯（HDPE）回收聚烯烃砌块。这些砌块通过滚塑工艺制造。此外，还研究了砌块的机械、物理、抗冲击和燃烧性能。总之，在已进行的测试中，HDPE表现得比PP更好。
