connected with no weld area. The concrete structure was initially made with a width‚ breadth and height of 1m. The area where the bolt would be placed was cut out using the cut extrusion function in ABAQUS. Due to the large design of the concrete block‚ it is difficult to define a workable size mesh for the problem‚ as can be seen in Figure 24 and 25. Figure 24:Assembled concrete block and bolt showing concrete area compared to the bolt area Figure 25:Assembled concrete block and bolt with mesh During

The bridge was designed by the French structural engineer Michel Virlogeux and British architect Norman Foster. The bridge opened in 2004 on 16th December after costing around €400 million. The Construction of the Millau came in three parts: the concrete‚ the steel and then the final construction. The Viaduct used many different specialties in the field of civil engineering and innovations in their approach to construction of the bridge‚ which cut costs and increases speed of construction.

Test 6. Conclusion 1. Introduction The purpose of this laboratory was to first test the effect that increasing water content would have on the workability of fresh concrete‚ completed by way of a slump test. The second part of the laboratory was to check what the influence of a superplasticiser would have on workability of fresh concrete‚ this was completed by completion of a Vebe test. 2. Materials and Equipment - Slump Equipment used within the slump test: 1. Slump Cone‚ Rod‚ Base plate Sampling

formwork is a rapid pace construction system for forming cast in place concrete structures. Formwork the term given to either temporary or permanent molds into which concrete or similar materials are poured. In the context of concrete construction‚ the “falsework” supports the shuttering molds. This formwork is built out of prefabricated modules with a metal frame (usually steel or aluminum) and covered on the application (concrete) side with material having the wanted surface structure (steel‚ aluminum
