An Introduction to 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...

An Integrated Construction Management System for Site Precast Concrete

In order to manage site precast concrete construction which has been increasing, an integrated construction management system employing a unique 3-D modelling method and analogue process input method was developed. At the planning stage, the system supports interactive planning between member configuration and installation planning by a visual method and with an accurate quantity. At the proces...

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 ...
