Shrinkage in concrete or mortar depends on a number of factors • Cement concrete: Richer the mix greater is the drying shrinkage. • Water content: More water in mix induces greater shrinkage • Aggregates : Large aggregates with good grading has less shrinkage for same workability as less water

Therefore‚ the operational strategy has direct implications on the process flow‚ the output‚ the human resource management and the bottom line of each company. McDonald’s uses a batch process to cook hamburgers (Exhibit A). Using a batch process means that the speed of delivery is dependent upon the speed and experience of the individual worker. Hamburgers are cooked on a large platen‚ in batches of up to twelve. Two or more batches may be on the platen at one time‚ in various stages of cooking. This

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

Due to such a low tensile capacity‚ flexural cracks develop at early stages of loading. In order to reduce or prevent such cracks from developing‚ a concentric or eccentric force is imposed in the longitudinal direction of the structural element. This force prevents the cracks

a lot of concrete and descriptive language in his work. Langston Hughes’s essay “Salvation” uses detailed descriptions to impact the reader. 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

Piaget and Vygotsky: Similar Differences People recognize that Jean Piaget and Lev Vygotsky are two of the most influential thinkers in the world of developmental psychology. These two theorists are similar in several ways but are also different in at least one key area (Lourenço‚ p. 282). It is important for educators to understand the philosophies of each in order to become familiar with how children develop so that their students can receive the most benefit from instruction.

Many are used today to determine when a child is mature‚ when they can feel emotion‚ and other important factors to which there are no strict textbook answers for. Piaget and Vygotsky are two theorists that offer theoretical perspectives on how a child develops. 2. Piaget’s Constructivist Theory of Cognitive Development: Piaget had a phrase that said "Assimilation and Accommodation lead to Adaptation." Assimilation is when a person fits his or her external information in with what he or she
