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...

Laminated concrete slabs can deliver desirable structural properties and effectively improve the speed of construction. According to their basic specifications, laminated comprise a 60 mm precast slab 70 layer cast in situ, with steel truss bar at height 80 mm. This paper studies effects on mechanical slabs. A simple but accurate method is proposed for calculating stiffness The test results sho...

This research investigates the development and evaluation innovative methods for the use of conductive concrete as an electromagnetic shield. New testing methods are developed to determine the best conductive components to use in the design of a concrete mixture for shielding that shows the best promise. The conductive concrete mixture has the potential to provide electromagnetic shielding that...

The State of Florida has developed a draft radon standard for new residential construction. A study was conducted to evaluate the effectiveness of the standard's features in controlling radon entry in new houses built over relatively high radon potential soils. Special attention was given to foundation preparations and slab placements to insure that the draft standard requirements were being me...

Synopsis: The structural design for the East Addition to the St. Cloud Hospital facility in central Minnesota incorporated punching shear and cracked section design criteria that are not currently specified in ACI 318-05. The complexity of the column layout and shallow floor-to-floor spacing were the primary reasons for choosing a twoway 12 in. (300 mm) reinforced concrete flat slab for the 450...
