TESTS ON MORTAR

The following tests are conducted on the prepared mortars to ensure their quality!

1. Crushing Test
2. Tensile Strength Test
3. Adhesive Test.

1. Crushing Test: This test is carried out on a brick work with the mortar. This brick work is
crushed in a compression testing machine and the load is noted down. Then the crushing strength is
obtained as load divided by cross-sectional area.

2. Tensile Strength Test: The mortar prepared is placed in a mould of bricket which has central cross-sectional area as 38 mm × 38 mm. After curing the briquette is pulled under the grips of tensile testing machine. The ultimate load noted. Then the tensile strength of mortar is load divided by the central cross-sectional area.

3. Adhesive Test: Two bricks are joined together with mortar to be tested. The upper brick is suspended from an overhead support. A board is hung from the lower brick. Then weights are added to the board till the bricks separate. The adhesive strength is the load divided by area of contact.

Particle-Size Analysis of Soils ASTM D422

Particle-Size Analysis of Soils  ASTM D422 GRAIN SIZE ANALYSIS SIEVE & HYDROMETER ANALYSIS Purpose : This test is performed to determine the percentage of different grain sizes contained within a soil. The mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles. Standard Reference : ASTM D 422 - Standard Test Method for Particle-Size Analysis of Soils Significance : The distribution of different grain sizes affects the engineering properties of soil. Grain size analysis provides the grain size distribution, and it is required in classifying the soil. Equipment : Balance, Set of sieves, Cleaning brush, Sieve shaker, Mixer (blender), 152H Hydrometer, Sedimentation cylinder, Control cylinder, Thermometer, Beaker, Timing device. Test Procedure: Sieve Analysis: (1) Write down the weight of each sieve as

Slump Test of Concrete ASTM C143 [Urdu & Hindi]

Image
Slump Test of Concrete ASTM C143 [Urdu & Hindi] *Scope* The concrete slump test measures the consistency of fresh concrete before it sets. It is performed to check the workability of freshly made concrete, and therefore the ease with which concrete flows. It can also be used as an indicator of an improperly mixed batch. The test is popular due to the simplicity of apparatus used and simple procedure. The slump test is used to ensure uniformity for different loads of concrete under field conditions. The program requires a working knowledge of the following ASTM test methods and practices. Referenced Documents ASTM Standards: • C31/C31M Practice for Making and Curing Concrete Test Specimens in the Field. • C138/C138M Test Method for Density (Unit Weight), Yield, and Air Content (Gravimetric) of Concrete. • C172 Practice for Sampling Freshly Mixed Concrete. • C173/C173M Test Method for Air Content of Freshly Mixed Concrete by the Volumetric Method. • C231 Test Method for Air Con
