Jul 26, 2016 · The Benefits of Using Concrete. We’re often asked how concrete compares to other building materials. Concrete offers many benefits: It’s easy to have concrete delivered to building sites. It’s also strong, fire resistant and durable. However, we think these five reasons are key to its popularity. It’s a Low-Maintenance Building Material

Based on the characteristics of CF/PEEK, a new manufacturing process is proposed for CF/PEEK sandwich structure. • A novel in-suit hot-pressing connection technology is proposed for the connection between the panel and the truss core.. The FE model provide a way for designers to study the low-velocity impact response of FRP sandwich structures.

Prestressing is a technique of introducing stresses into a structural member during fabrication and/or construction to improve its strength and performance. This technique is often employed in concrete beams, columns, spandrels, single and double tees, wall panels, segmental bridge units, bulb-tee girders, I-beam girders, and others.

Reductions in thermal conductivity and improvements in fire resistance criteria were also observed in comparison with conventional lightweight concrete mixtures. For example, measured thermal conductivity values ranged from 0.092 W/m.K to 0.177 W/m.K, and the insulation criterion (an indicator of resistance to fire) reached up to 110 minutes
