BULKING OF SAND TEST

 BULKING OF SAND TEST

AIM:

To determine the bulking of fine aggregate.

APPARATUS REQUIRED:

1. Measuring jar  250ml



SAMPLE:

The cement taken should be finely ground material which of addition of requisite quantity of water is capable of hardening both under water and in air by the chemical interaction of its constituents with water and capable of binding together the appropriate materials. (Reference IS: 3535 - 1986)

PROCEDURE:

1. In a 250ml measuring jar pour the sand until it reaches the 200ml 

2. Then fill the cylinder with water and stir the sand well (The water shall be sufficient to submerge the sand completely)

3. Now the sand surfaces will be below its original level

4. Then note the level of sand as "y"

CALCULATION:

Percentage of bulking of sand = ((200/y)-1) x 100

NOTE:

Acceptable Value – Bulking of sand value should not be more than 10% 

REFERENCE:

IS: 2386 (PART 3) – 1963.

  SPECIFIC GRAVITY TEST OF COARSE AGGREGATE AIM: To determine the Specific gravity of the aggregate using Pycnometer . APPARATUS REQUIRED: 1. Pycnometer of about 1 litter capacity 2. Weighing balance, with an accuracy of 1g.                  3. Vacuum pump  4. Oven                                                                                           SAMPLE: The sample of 2000g to 1000g of aggregate shall be taken for tested. The aggregate which have been heated artificially shall not be taken. Reference IS: 2386 (Part III) – 1963 ). ads PROCEDURE: 1. A sample of 1kg for 10mm to 4.75mm size and 500gm for less than 4.75mm size. The sample is placed in a tray and fully covered w...

PARTICLE SIZE DISTRIBUTION TEST - SIEVE ANALYSIS

 PARTICLE SIZE DISTRIBUTION TEST - SIEVE ANALYSIS AIM: To determine the Particle Size Distribution of the Aggregate by Sieve Analysis. APPARATUS REQUIRED: 1. Set of IS Sieve           2. Weighing Balance PROCEDURE: 1. The test sample is dried to a constant weight at a temperature of 110 ± 5oC and weighed. 2. The sample is sieved by using a set of IS Sieves for 5 minutes. 3. On completion of sieving, the material on each sieve is weighed. 4. Cumulative weight passing through each sieve is calculated as a percentage of the total sample weight. 5. Fineness modulus is obtained by adding cumulative percentage of aggregates retained on each sieve and dividing the sum by 100. OBSERVATION: Tabulation for Coarse Aggregate: SI.No Sieve Size Weight Retained Cumulative Weight Retained Cumulative % Retained Cumulative % Passing 1 80     ...

  pH VALUE OF WATER AIM: To find out the pH value of water. APPARATUS REQUIRED: 1. Glass beaker of 250 ml capacity 2. One or two electrode pH meter. 3. Known pH solution buffer of standard strength. 4. A glass stirred rod 5. A thermometer SAMPLE Analysis of the sample will be carried out as soon as possible and preferably in the field test during the sampling. The pure water and water that are not in contact with the atmosphere will be collected in the container and stored capped before analysis. (Reference IS: 3025 (Part XI) - 1983) PROCEDURE: 1. A glass beaker is collected and washed. 2. The water sample to be tested is added to the glass beaker with the addition of the buffer solution and mixed vigorously. 3. Allow a minimum of one hour to allow the sample to stabilize its temperature by stirring occasionally as it waits. 4. Calibrate the pH meter temperature controller to the temperature of the sample. 5. Calibrate the pH-value using the standard solution. 6. Dip the el...
