POLYMER COCNCRETE 1. Introduction Despite being thought of as a modern material‚ concrete has been in use for hundreds of years. The word concrete comes from the Latin concretus‚ which means “mixed together” or compounded. Concrete is an extremely popular structural material due to its low cost and easy fabrication. Concrete is made up of sand or stone‚ known as aggregate‚ combined with cement paste to bind it. Aggregate can be of various sizes. It is broadly categorized as fine (commonly

placed in a cube and allowed to dry forming the concrete testing cube. Each of the four blocks containing different compositions of each material were then placed in a compressive testing machine and when each cube yielded‚ results were taken. Effect of water content on workability of fresh concrete: As more water was added to the dry mixture‚ it became easier to work with but we had to be careful not to add to much water or this would weaken the concrete and possible ruin the mixture.

Procedure for mixing concrete 1. Weigh out the designed proportions for a 1.6 cubic foot batch of concrete. a. Divide the water into two buckets‚ one with about 3/4 of the water. If using air entraining‚ put the air entraining agent in the 3/4 water bucket. 2. Put about half the coarse aggregate‚ half the fine aggregate and the 3/4 bucket of water with air entraining in the mixer. 3. Start the mixer and mix until the aggregate is thoroughly wet 4. Carefully add all the cement with the mixer

object thereby strengthening it. The idea of pretensioned concrete has been around since the late 19th century‚ but its use was limited by the quality of materials available at the time. It wasn’t until the 1920s that materials of a suitable quality were available in sufficient quantity to allow pretensioned concrete to be used with confidence. The pioneers of this field were Freyssinet‚ Magnel and Hoyer. Description: In pre-tensioned concrete tensile elements such as cables‚ ribbons‚ or rods are clamped

Description is “a sketch or account of anything in words; a portraiture or representation in language; an enumeration of the essential qualities of a thing or species” (“description”). Authors use concrete language to influence readers. Concrete language is “based off the five senses which are hearing taste‚ sight‚ touch‚ and smell” (“Concrete”). Hughes

Ray Bradbury’s The Illustrated Man: The Concrete Mixer Imperialism Ray Bradbury’s “The Concrete Mixer‚” tells the story of a Martian named Ettil‚ who refuses to invade Earth on the theory that the people of Earth have greater morale than the people of Mars. Ettil had feared that his people were doomed to the same fate as the people in his books: whom at the end of every story were conquered by Earth. When the Martians’ arrive to Earth nothing is as any of them thought it would be. They had been
