Sieve Analysis Test Lab Report Sample

Sieve Analysis Test Lab Report Paper The objective of this experiment is to obtain the grading curve for both fine and coarse aggregate. 1. Balance balance or scale used in testing fine and coarse aggregates shall have readability and accuracy as follows: For fine aggregate, readable to 0. 1 g and accurate to 0. 1 g or 0. 1 % of the test load. For coarse aggregate, or mixtures of fine and coarse aggregate, readable and accurate to SO g or 0. 1 % of the test load. 2. Sieves the sizes and apertures appropriate to the specification tot the material being tested, complying with BBS 410: For coarse aggregate, standard vive size of 50. Mm, 37. 5 mm, 20. 0 mm, 14. 0 mm, 10. 0 mm, 5. 0 mm and 2. 36 mm (Fig. CLC-l), Poor fine aggregate, standard sieve size of ICC mm, 5. 00 mm, 2,36 mm, 1. 18 mm, mm, 300 m and 150 m (Fig. ICC-2). 3. Mechanical Sieve Shaker a mechanical sieving device, used to create vibration of the sieve to cause the particles to bounce. 4. Oven an oven of appropriate size capable of maintaining a uniform tem perature of Acoustic. PROCEDURES Fine Aggregate I. Representative sample was chosen by quartering (according to BBS 812: Part 102: 1984) or by use of a sample splitter (Fig. CO-3). The sample to be tested should be the approximate weight desired when dry. For this experiment, about 500 grams of fine aggregate was weighed. 2. The samples was dried to constant weight in the furnace at a temperature of 1050 C. 3. The samples was cooled down. The desired sieves was nested in order of decreasing aperture size from top to bottom. 4 The sample was placed on the top sieve and the sieves was agitated by mechanical sieve shaker for a sufficient period so that after completion, not more than one percent by weight of the residue on any individual sieve will pass that sieve.

Psychology of Exceptional Children essays Teaching On-Task and On-Schedule Behaviors to High-Functioning Children with Autism Via Picture Activity Schedules. In this article, the authors set out to prove the importance of the development and future use of visual activity schedules. It is believed that the visual activity schedule system will promote independent functioning of students with autism spectrum disorders in their least restrictive environments. PECS, or Picture Exchange Communication Systems, was claimed in the article to be effective in teaching students to use a type of picture-based system in order to communicate socially. Visual prompts, such as pictures and words, are thought to help children to identify their play choices during free play. They also teach a variety of tasks to people with disabilities including cooking and basic cleaning and custodial skills. Also, of importance in todays society, is the fact that they have been useful in teaching autistic people computer skills. The main goal in this article was to teach children with low-functioning autism to follow the visual activity schedule, in order to complete daily living tasks. These tasks include getting dressed, washing laundry, and setting the table. The schedules used visual prompts to show the students what work was to be completed. Many autistic children have trouble going from one activity to another. The visual schedules gave the students a structured environment for learning and performing. Each students individual activity schedule was displayed in a 4 x 6 inch plastic photo album with four line drawn pictures of academic activities. A 2 x 2 photo card was placed in a transparent plastic envelope that allowed only one picture per page. After the children were introduced to the visual activity schedules, there were immediate positive increases in the level of performance. When the schedules were taken away, there was a decrease in the per...

The improvement in productivity is as a result of the synergy generated within the team. The synergy is built up as a result of a coordinated effort among the members of the team. Since a team relies on a coordinated effort, specialization within a team is highly imperative. This means that a team can comprise of members that perform specific specialized subtask that will be joined with the efforts of others to complete one whole task. In specialization, the team becomes more efficient since the actions performed by each member are limited to their scope and easy for them to achieve (Baldwin & Migneault 1996). Delegation of duty is another important aspect of teams. In management, team leaders can decide to allocate different tasks to members as they deem fit. The criteria used in delegation can be based on talent and capacity of the different members of a group. The result of this effective delegation process is that each member will be awarded
