[11] After the incident an investigation was started among buildings using the same flooring system, leading to the closure of several buildings in the Netherlands, including one at the ...
The derivation of the maximum arching moment of resistance of laterally restrained concrete bridge deck slabs utilised Rankin's [21] idealised elastic-plastic stress-strain criterion for concrete, valid for concrete cylinder strengths up to at least 70N/mm 2, which he had derived on the basis of Hognestad, Hanson and McHenry's [23] ultimate ...
However, this study concerned hollow concrete blocks and its results are unverified for concrete slabs. The actual value of k varies significantly in practice, and is usually between 0.8 and 2.0 W m −1 K −1. [8] This is relatively high when compared to other materials, for example the conductivity of wood may be as low as 0.04 W m −1 K −1.

Developed initially in the mid-1920s, it has expanded into widespread use. It is most suitable for producing concrete-like blocks [1] and as an eco-friendly alternative to such.
