Considerations on Fast Neutron Albedo for Iron, Concrete and Iron-Covered Concrete Slab

Effects of Half-Precast Concrete Slab System on Construction Productivity

A half-precast concrete slab system (HPCSS) is reported to exhibit excellent structural performance when compared with traditional slab systems. However, there is a lack of extant research examining the construction issues of an HPCSS. Thus, in this study, we analyze the construction process and productivity of applying an HPCSS by using a simulation method with the data collected from an actua...

Computer simultion of concrete slab-on-grade construction

This paper presents a decision support system for contractors specialized in concrete floor finishing, making optimal use of available technology in automation. The paper presents a computer simulation model for concrete slab-on-grade construction considering different levels of automation that integrate conventional manual, semi-automated, and robotic work processes. The data used in the simul...

Rheological and Mechanical Properties of Light Weight Self-Compacting Concrete Containing Sirjan Iron Mine Waste

Recycling is a logical option for materials that are not suitable for composting. One of these materials is iron mines waste that, according to their compounds, can be used as a substitute part of cement in concrete. For this aim, rheological and mechanical properties and durability of light weight self-compacting concrete (LWSCC) containing Sirjan iron mine waste (SIMW) as partial substitute o...

Steel, Cast Iron and Concrete: Security Engineering for Real World Wireless Sensor Networks

What are the real security issues for a wireless sensor network (WSN) intended to monitor the structural health of a suspension bridge, a subway tunnel or a water distribution pipe? Could an attack on the sensor network cause the structure to collapse? How easy is it for civil engineers or other domain experts to build a secure WSN using commercially available hardware and software? We answer t...
