The particle size distribution of output material is affected by type of crusher used .The demolition debris of particle size less than 37.5 mm. The inclusion of upto 15% of particle larger than 37.5 mm should not alter density significantly. Water absorption of coarse and fine particle of crushed brick aggregates passing 19 mm 4.75 mm respectively and retaining on 4.75 mm are 6.15 % and 6.20 %...

We present a method for a structural simulation of destructible 3-dimensional metal frame buildings at interactive frame rates. Beams, floor slabs, and wall sections are simulated as rigid bodies and joined together by rigid constraints. Each constraint is given a set of breaking thresholds for the force and torque around each axis, allowing them to fail if the structure is overloaded or damage...

This e-fact aims to raise awareness of the occupational safety and health (OSH) risks associated with the planning and construction of green buildings, their maintenance, renovation (retrofitting) and demolition, as well as the collection of related construction or demolition waste on site (excluding the subsequent waste treatment and recycling). Some of these OSH risks are new compared with tr...

Present schemes involving the quantum non-demolition interaction between atomic samples and off-resonant light pulses allow us to store quantum information corresponding to a single harmonic oscillator (mode) in one multi-atomic system. We discuss the possibility of involving several coherences of each atom so that the atomic sample can store information contained in several quantum modes. This...

8 Demolition of buildings produce large quantities of particulate matter (PM) that could be inhaled 9 by on-site workers and people living in the neighbourhood, but studies assessing ambient 10 exposure at the real-world demolition sites are limited. We measured concentrations of PM10 11 (≤10 μm), PM2.5 (≤2.5 μm) and PM1 (≤1 μm) along with local meteorology for 54 working hours 12 over the demo...

A quantum protocol for bit commitment the security of which is based on technological limitations on non demolition measurements and long-term quantum memory is presented.

With the increasing focus on construction sector (e.g., following European Green Deal initiative) with aim to reduce emissions by 55% 2030 (compared 1990 levels), as well achieve full decarbonisation 2050, built environment remains a strategic domain for R&I (Research and Innovation) agenda. Indeed, building is main contributor greenhouse gas (39% of global 2018), highlighting need start pr...
