What is difference between pre tension and post tension precast girders of bridge?
A simple explanation: PRE tensioned- cables are tensioned, and the concrete is cast around it. The tensioning is done BEFORE casting the concrete (PRE = before). POST tensioned- cables are placed inside of ducts or are greased to prevent bonding to the concrete, the concrete is cast around the cables, and then the cables are tensioned after the concrete has reached a desired strength. The tensioning is done AFTER the concrete is cast (POST = after).
What are concrete structural insulated panels?
Some concrete structural insulated panels are sandwich panels. These have layers (also called wythes) of: * structural concrete (designed to bear the loads once the panel is installed) * insulation (usually foam such as polystyrene, extruded or expanded) and may also have layers of: * non structural concrete (on the other side of the insulation from the structural concrete) * wall lining materials * waterproofing The wythes of concrete are structurally attached to each other with jointers through the insulation wythe, that are made from strong materials with a low thermal conductivity (such as fibreglass) to reduce the thermal bridging of the insulation. The panels are made by pouring concrete on beds at concrete precasters or on a suitable area such as a floor slab on site, and are built up in these layers. There are several proprietary brands of jointers and various panel design options.
Why is it that that concrete is stronger at bottom of column than on top?
when concrete is vibrated while pouring in to the form work, the cement slurry part tends to get drained through voids between aggregates and the richest part of cement slurry is detained at bottom portion of column. this causes a strong, dense, and void free concrete which ensures better compressive strength than the concrete on top portion of column.
