Aggregate Impact Value Test. AIV test is conducted to determine the Aggregate Impact Value of Coarse aggregate. The aggregate impact value gives a relative measure of the resistance of an aggregate to sudden shock or impact, which in some aggregates differs from Its resistance to a slow compression load.
Discussion and Conclusion The line of best-fit is used to find the gradient, the T2/L value, if straight or linear it shows that the relationship between the two is directly proportional. Using the original equation, you can square both sides and rearrange it to make . Then you can input the gradient value …
2.0 THEORY 2 Basically the Aggregate Impact Value (AIV) is the percentage of fines produced from the aggregate sample after subjecting it to a standard amount of impact. The standard amount of impact is produced by a known weight, i.e. a steel cylinder, falling from a set height, a prescribed number of times, onto of aggregate of a standard ...

As a student, you should know how to write an analysis for a lab report because at some point, you will be required to write a lab report or an analysis for a lab report. A lab report analysis is simply a shortened lab report that highlights the analysis of the data that was collected during a laboratory experiment only- infohost.nmt.edu .
Report: A sample lab report for this activity is provided as an example for you to follow when writing future lab reports. Sample Lab Report: Experimental Investigation of C/D Abstract. In this investigation, we examined the hypothesis that the circumference (C) and diameter (D) of …
Aggregate Impact Value. The test sample shall consist of aggregates the whole of which passes through ½ in B.S. test sieve and is retained on a 3/8 in B.S. test sieve. The aggregate comprising the test sample shall be dried in an oven for a period of four hours at a temperature of 100-110 °C and cooled.The measuring cup shall be filled about ...
Procedure. Step 1 – First, the aggregate sample sieve through 12.5mm sieve and collect it which is retained in 10 mm sieve. Step 2 – Now, the sample should be dried through the oven up to 4 hours at 100 deg to 110 deg. Step 3 – Then, the aggregate sample should be filled in the metal cup by 3 layers. Each layer should be tamped 25 times by the tamping rod.
SAMPLE LAB REPORT. Abstract. The theory of optimal foraging and its relation to central foraging was examined by using the beaver as a model. Beaver food choice was examined by noting the species of woody vegetation, status (chewed vs. not-chewed), distance from the water, and circumference of trees near a beaver pond in North Carolina.
In this lab, we performed a Charpy impact test on three different types of steels (hot- rolled C1018, cold-finished C4140 alloy steel, and cold-finished C1095 carbon steel) testing each variety at three different temperatures (22.6°C, 0.1°C, and -80.0°C).
What this handout is about. This handout provides a general guide to writing reports about scientific research you've performed. In addition to describing the conventional rules about the format and content of a lab report, we'll also attempt to convey why these rules exist, so you'll get a clearer, more dependable idea of how to approach this writing situation.
measured absorbance value of each sample into the standard curve equation. Note that the table shows the results for all five laboratory groups, each of which developed a slightly different stan-dard curve. Table 2: Analytical Phosphate Concentration in g/L Sample No. Identification Group 1 Group 2 Group 3 Group 4 Group 5
Aggregate impact value is the ratio of the weight of the fraction passing through 2.36 mm (weight W2) by the total weight of the sample (weight W1 + W2). Aggregate Impact Value = (W2/ (W1+W2)) * 100 = 80 gm / 300 gm = 26.67 (Impact Value) Where, W1= Weight of …
Writing a Science lab report. Many of your Science units will require you to write a formal laboratory report.

Guidelines for a Physics Lab Reports A laboratory report has three main functions: (1) To provide a record of the experiments and raw data included in the report, (2) To provide sufficient information to reproduce or extend the data, and (3) To analyze the data, present conclusions and make recommendations based on the experimental work.
Ten control frogs were given injections of 1.0 ml of a .9% NaCl solution. All frogs were maintained in 3 m square tanks at 25 0 C for 1 day in 1 inch of water. At this time each frog was placed on an open floor and induced to jump 3 times by slapping the ground behind the frog. The jumping distance was defined as the average of the 3 jumps.
Lab Report Format A typical lab report would include the following sections: title, abstract, introduction, method, results and discussion. Title page, abstract, references and appendices are started on separate pages (subsections from the main body of the report are not).
