Sieve Analysis Test Lab Report

To calculate the effective diameter of the particles, we use Equation 1 provided below. To determine the effective diameter of the particles, we needed to have the hydrometer readings and temperature for each time taken, as well as using the Coefficient of temperature adjustment table provided in Appendix 3 and the Hydrometer 152H length readings in Appendix 4. To able to determine the Percent Finer for Hydrometer, we use Equation 2 provided below as well as Equation 3 for the Dry Weight of Soil provided below. For Equation 2, we also need the Specific Gravity correction for percent finer table to be able to solve Equation 2. The Specific Gravity correction for percent finer table is provided in Appendix 5. Furthermore, to determine the total

3) Bag 3 will be filled with distilled water and beaker 3 will be filled two-thirds of distilled water. After the bags and beakers are prepared, the bags should not be placed in the beakers at the same time. Each bag will be weight before placing each bag in their correspondent beaker and the weight will be recorded, this process will be repeated every 15 minutes for a total of

Introduction: Accuracy and precision were the major aspects of the lab. Accuracy is how close the average of the measured values are to the actual value. Precision is the closeness of repeated measurements. In the lab, the aim was to get as close as possible with both accuracy and precision when determining the mass and volume of the spheres. The mass was determined by weighing the spheres on the Analytical Scale and Triple Beam Balance Scale. The volume is determined by measuring with a ruler and by water displacement. The standard

precipitate; then pour over the solid in the funnel. Finally, pour two 10-mL portions of

The surface of all specimens is test, either in the laboratory or in the field, should be smooth to the touch and free of joints, fractures, or other obvious localized discontinuities to a depth of at least 6 cm. In situ rock shall be flat and free of surface grit over the area covered by the plunger. If the surface of the test area is heavily textured, grind it smooth with the abrasive stone.

The RAP sample is heated in the furnace at the 538 C temperature until the difference between consecutive measured mass loss does not exceed 0.01 % of the sample mass for three consecutive 1-min intervals. This point shall be determined automatically by the furnace’s data collection system. The furnace’s data collection system shall measure and record automatically the aggregate mass of the sample after ignition to the nearest 0.1 g. The mass shall be obtained immediately upon completion of tests by subtracting the mass loss measured by the furnace from the initial mass of the mix. The corrected asphalt

In other words, since there is no standard quantitative description employed in the geotechnical domain for the particle’s shape, ignorance took place. Nevertheless, many researchers (e.g., Michell and Soga, 2005; Arasan et al., 2010, and Rodriguez et al., 2013) agreed to define the particle shape as shown in Figure 1 and Table 2. Furthermore, Table 3 illustrates some definitions for quantitative descriptors mentioned by many authors. Santamarina and Cho, 2001 & 2004; Cho et al., 2006, and Rosé et al., 2008 manifested the influence of the particle's roundness R on the void ratio range of different sands, as illustrated in Figure 2a. While Miura et al. 1997 & 1998 proposed A2D to the correlations of the void ratio range at a specific given D50, as shown in Figure 2b, also, they pointed out that most of the natural sand samples have A2D between 300-600. Additionally, Chapuis, 2012, proposed empirical formulas for emax and emin with the roundness factor of the particles as in Equations 12 & 13 respectively depending on data gathered by Youd, 1973, and Krumbein and Sloss, 1963.

5. After being rotated, the sample is removed from the drum and is sieved on no. 12 sieve. Later the sample that is retained on the sieve is washed and dried at the temperature of 1050C to 1100C. The weight of the sample is taken after the sample is cooling down.

Combination type SCC: This mix is obtained by adding a low amount of stabilizer or the powder type SCC to neutralize the moisture fluctuations. The target water-to-cement ratio is 0.4. Because of the increased amount of water in this mix, a lower amount of HRWR is used than in the powder-type SCC mix. Compared to powder-type mix, the combined mix design shall have a larger coarse aggregate content and a reduced amount of fine

As Simoni and Houlsby (2006) mentioned, the small dimension of the standard shear-box apparatus in laboratory testing of coarse granular material will cause a problem. Because the maximum grain size that can be tested rarely exceeds 10 mm with standard apparatus. Thus, it is necessary to limit the sand fraction in this size. However, this cannot completely simulate the real situation. An alternative approach is using a suitably large shear test apparatus. But the costs will often too expensive and that is what makes this alternative unjustifiable. Hence, compared with doing tests in laboratory, computer simulating become a better

Concrete is an artificial material in which the aggregates are bonded together by the cement when mixed with water. With the advancement of technology and increased field of application of concrete and mortars, the strength, workability, durability and other characteristics of the ordinary concrete can be made suitable for any situation. For this, definite proportions of cement, water, fine aggregate, coarse aggregate, mineral admixtures and chemical admixtures are

Abstract— Concrete is a composite construction material composed of aggregate, cement and water. There are

This experiment shall be repeated twice or more to enhance accuracy of the results obtained. Besides detecting systematic errors, this experiment would aid on the technique and understandings to the correct use of these equipments.
