Safety Assessment in Installation of Precast Concrete

Precast Concrete Elements

Lattice-girder floor slabs and double-wall elements have been successfully used in building and industrial construction for decades. These precast elements of 50 – 70 mm thickness serve as permanent formwork for the subsequently added in-situ concrete creating a monolithic structure. The high prefabrication level allows the construction period to be significantly minimized. The main goal is the...

Foam Concrete Precast Elements in Composite Concrete-GFRP Plate Girders

This paper is focused on using foam concrete as structural element in polymer-concrete composite plate girders. Trial mixes of foam concrete and different proportions of foam agent were considered to obtain the suitable mix that can be used as structural element in composite girders system. Details of the experimental investigations on foam concrete precast slabs and polymer-concrete composite ...

Proactive training system for safe and efficient precast installation

a r t i c l e i n f o The construction industry is a crucial component of the Hong Kong economy, and the safety and efficiency of workers are two of its main concerns. The current approach to training workers relies primarily on instilling practice and experience in conventional teacher–apprentice settings on and off site. Both have their limitations however , on-site training is very inefficie...

Advantages of Large Strands in Precast/Prestressed Concrete Highway Application

The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...
