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...
متن کاملFoam 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 ...
متن کاملChromate and amine contact allergies in workers manufacturing precast concrete elements.
BACKGROUND Five workers from a plant manufacturing concrete wall panels and beams were referred to our department because of suspected occupational dermatitis. When patch tested, 3 workers reacted to potassium dichromate. Four workers reacted to ethylenediamine dihydrochloride, without any obvious exposure. Owing to the high proportion of workers with recent-onset skin disease, an investigation...
متن کاملPhantom Elements and Its Applications
In our previous work[11] , a relation between Tsukiyama problem about self homotopy equivalence was found by using a generalization of phantom map. In this note , fundamental result is established for such a generalization. This is the first time one can deal with phantom maps to space not satisfying finite type condition. Application to Forgetful map is also discussed briefly.
متن کاملSkeleton morphogenesis: Defining the skeletal elements
The vertebrate skeleton consists of a variety of individual elements, each characterized by a specific size and shape. There are two main modes by which these skeletal elements are formed. In one mode, known as ‘intramembranous ossification’, which occurs for example in the development of the skull, mesenchymal cells directly differentiate into bone. In the other mode, known as ‘endochondral os...
