Introduction
In order to construct and completely understand the significance of the materials necessary to build a robust bridge, multivariate factors need to be deduced. These include; the location, the material of the steel and the characteristics of the cement mixture.
Of the aforementioned factors, location is significant in informing Material Engineers regarding the type of environment in which the structure is built. The environment thus plays a pivotal role and governs the formation of cement and the type of steel utilised. In this scenario, the proximity of the bridge to the river enables us to infer the presence of specific ions and particles, which must be considered prior to ascertaining the most effective proportions of concrete. …show more content…
The chemical properties need to be able to act as a barrier between the B2 environment whilst maintaining strength. Overall the first mixture was better when the Porosity Reducing Agent was added however the second mixture provided better Compressive Strength, Length Change in Sulphate Solution, Chloride Diffusion and Water Permeability. The first mix was superior in shrinkage which isn’t an ideal factor considering the criteria. (“Durability Performance of Australian Commercial Concrete Modified with Permeability Reducing Admixture”). Thus Mix 2 is the final recommended mix for the final …show more content…
This occurs due to the different coefficients of thermal expansion thus maintaining 0.03% Silicon and Phosphorus concentration so the interaction doesn’t occur.
According to the Australian Standard AS 5100 (Design Bridge), handrail component which are not made of stainless steel need to be hot dip galvanised to reduce the time of maintenance. Further since galvanizing requires less maintenance, it is overall recommended that components have galvanizing treatments.
Part C
Impact testing is usually applicable for all realms of performance testing as it measures the objects ability to absorb energy.
The most suitable tests for hand-railing being held on two sides would be the Charpy V-notch impact test; this evaluates the impact resistance of an object being held the two sides. For barrier posts the Izod test would be more suitable as it approximates the loading characteristic of the post when impacted by a vehicle.
Both tests should adhere to the Australian standard AS 1544 (Method for impact tests on metals). These tests are the avenue upon which the AS 5100 (Bridge Design) are deigned upon. As after passing the impact tests conditions of real situations are implemented confirming whether or not the material is completely suitable or
