RPC represents a new class of Portland cement-based material with compressive strengths in excess of 200 MPa range. By introducing fine steel fibers, RPC can achieve remarkable flexural strength up to 50 MPa. The material exhibits high ductility with typical values for energy absorption approaching those reserved for metals.

Modelling hybrid reactive powder concrete T-beams
Abstract The purpose of current study is to evolve a nonlinear finite element model to simulate the influence of the type of concrete on reactive powder concrete (RPC) T-beams. Four simply supported T-beams were modelled and the difference is in the type of concrete (full normal strength concrete (NSC), full RPC, RPC in the web only, RPC

Host‐Guest Doping Enables Room Temperature Phosphorescence from Triarylboranes
While pure triarylboranes show RTP in annealed PMMA films, they do not in crystalline form, contrary to our previous report. However, crystalline host‐guest triarylborane systems show persistent afterglow up to 8 s even at 1 ppb guest loading. Computations identify triplet‐triplet energy transfer as the mechanism governing this efficient RTP.

A Termite‐Inspired Alternative to Cement
A termite‐inspired composite of clay, cellulose, and lignin forms a dense fibrous network with concrete‐like strength (32 MPa) and superior elasticity, processed at ambient temperature. Abstract Clay combined with organic materials is used by termites as a strong and durable construction material for their mounds with minimal environmental impact. Here,
