House Recycled
… transformation process, where components can be recycled and reused, similar to how chemical elements can cycle naturally in the environment. 5. Buildings should be designed for rapid transport, assembly, and disassembly. They should not require specialized construction workers for installation. …

Mitigating alkali silica reaction in recycled concrete
<p>Concrete made with recycled concrete aggregate (RCA) that had shown alkali silica reaction (ASR) distress was evaluated. It was found that ASR mitigation was needed to prevent continued expansion. Several mitigation methods were evaluated and compared to conventional concrete using the testing …

Investigation of mechanical properties of recycled polypropylene
… quality is reduced. Some plastic material can be recycled over and over again. This research concerns the number of times polypropylene (PP) formed by the injection mouldlng process can be recycled. The work focuses on the quality of the materlal dter each recycling operation Material was passed …
