The traditional building materials for bridges are stones, timber and steel, and more recently reinforced and pre-stressed concrete. For special elements aluminum and its alloys and some types of plastics are used. These materials have different qualities of strength, workability, durability and resistance against corrosion. They differ also in their structure, texture and color or in the possibilities of surface treatment with... [Read More] |

Cement can be defined as the bonding material having cohesive & adhesive properties which makes it capable to unite the different construction materials and form the compacted assembly. Ordinary/Normal Portland cement is one of the most widely used type of Portland Cement. The name Portland cement was given by Joseph Aspdin in 1824 due to its similarity in colour and its quality when it hardens like Portland stone.Portland stone is white grey limestone in island of Portland, Dorset....

The liquids used were water (the control), carbonated water, orange juice, ammonia, and bleach. Uniform cement blocks were made out of equal parts of dry cement and each liquid. Each block was tested for flexural strength and impact energy. For each type of cement three measurements were taken by dropping a one-pound weight on a fragment starting at one-foot heights and then increased the height until the fragment fractured.....
