Placing and Finishing Concrete

Placing and Finishing Concrete Some of the main requirements for the placing of concrete are: even spreading, concrete quality ensuring, balance on air content, homogeneity and water-cement ratio. The deliverables of placing is to avoid segregation and aid compaction of concrete. Concrete is a plastic material, so it can be molded into any shape. In…

Curing of Concrete | Advantages of Concrete

Curing of Concrete For the hardening of concrete through the setting of constituent components and to promote the reactions in the concrete, curing is carried out. Curing is needed for three main reasons, i.e. for the dissipation of heat, to reduce the moisture loss due to evaporation, and to maintain moisture for hydration. Curing helps…

Factors to Consider When Choosing a Metal 

Factors to Consider When Choosing a Metal Corrosion The main disadvantage of steel is that it rusts. It needs to be protected by a coating that doesn’t corrode, such as paint or non-ferrous metal. Roofing iron is coated with zinc, which doesn’t corrode in air or water. If the surface is meant to be shiny and…

Effect of  Alloying Elements in Cast Iron

Effect of  Alloying Elements in Cast Iron Besides carbon, cast iron contains sulphur and phosphorus as impurities from the process, alloying elements such as silicon and manganese, which significantly influence the properties of the cast iron. Nickel, chromium-vanadium, copper are other metallic elements which are added in a varying amount to have specific properties. Effect…

Factors Affecting Microstructure of Cast Iron

Factors Affecting Microstructure of Cast Iron  The structure of Cast iron is affected by the following factors: Carbon Content The higher the iron’s carbon content, the greater will be the tendency for it to solidify grey. To ensure that the structure is completely graphitic, the carbon content is kept less than 2 per cent when…
