Lab reports are the most frequent kind of document written in engineering and can count for as much as 25% of a course – yet little time or attention is devoted to how to write them well. Worse yet, each professor wants something a little different. Regardless of variations, however, the goal of lab reports remains the same: document your ...
Dec 03, 2013· MATERIALS AND METHODS: The instructor handed out an unknown test tube, labeled as number 125. The methods and tests learned through out the semester were used on this test tube in order to identify the two unknown microorganism; one a Gram positive and the other a Gram negative.
Lab 3 – Tension Test Objectives Concepts Background Experimental Procedure Report Requirements Discussion Objectives Experimentally determine the yield strength, tensile strength, and modules of elasticity and ductility of given materials. Concepts The linear relationship is Hooke's Law that represents elastic deformation. If the
LAB. 4) we followed this test by LAB. 5) This lab we had several problems and variations. Firstly we did not sample the aggregate properly. Secondly, the sample appeared to be dry but was not oven dry. Also, the machine was not run for the full 10 mins.
Reduce report turnaround time by performing data entry/capture as part of the testing workflow (in the field or the laboratory) and electronically reviewing, approving and distributing reports. Uniform Test Reports. Ensure consistent reporting formats between individual tests .
SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES AASHTO T 27 SCOPE The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design, ...
Checking of materials is an essential part of civil engineering as the life of structure is dependent on the quality of material are the tests to be conducted to judge the quality of cement. 1. Fineness 2. Soundness 3. Consistency 4. Initial And Final Setting Time Of Cement

measured during the torsion test. A formal lab report describing your work is due two weeks after your lab session. The following two items must appear in your lab report: Table 1: A table with 6 columns is shown on the following page. Complete the first 5 columns of this table using the data collected during the torsion test.

Resistance to abrasion Index of aggregate quality; ASTM C 131 (AASHTO T 96) Maximum percentage of and degradation wear resistance of floors and ASTM C 535 weight loss. Depth of wear
The test sample consists of aggregates passing sieve and retained on 10mm sieve and dried in an oven for four hours at a temperature 100 0 C to 110 0 C and cooled. Test aggregates are filled up to about onethird full in the cylindrical measure and tamped 25 times with rounded end of the tamping rod.
Construction Materials Testing. This handbook is intended for information and use by accredited construction materials testing laboratories, assessors conducting onsite assessments, laboratories seeking accreditation, other laboratory accreditation systems, users of laboratory services, and others needing information on the requirements
Sieve Analysis Test . Testing objectives: The Standard grain size analysis test determines the relative proportions of different grain sizes as they are distributed among certain size ranges.. Need and Scope: The grain size analysis is widely used in classification of soils. The data obtained from grain size distribution curves is used in the design of filters for earth dams and to determine ...
unit weight, gradation characteristics and compaction methods to permeability and resilient modulus using laboratory test results. Based on the statistical parameters, these models were found to be significant in predicting the k and M R values of aggregates and gradations used in this study. The laboratory .
When writing a lab report, it is often a good idea to begin by writing the Materials and Methods section. This section is usually very straightforward, and writing it first helps many people establish the proper thought process and understanding of the work that will allow the rest of the report .

Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate, including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M.
