2.2 Anchor Strength Requirements: Table 261-1A of the 1997 NESC specifies strength factors (equal to 1.0 for both Grade B and Grade C construction) with which the established holding power of anchors are to be multiplied. Rule 264 of the 1997 NESC requires that an anchor and rod assembly have an ultimate strength not less than that of
ASTM D2487-17 not only describes the Unified Soil Classification System for classifying mineral and organo-mineral soils for engineering purposes, but it also details the specific procedures for laboratory determination of the different soil classification groups. ASTM D2487-17 revises and supersedes the 2011 version of the same standard.
Your strength levels land you in the top 1% of humanity. Very Strong - In the muscle building and strength training realm, this would be considered intermediate level strength. Strong - Your lifts are around a 200 raw bench, 300 raw squat and 400 raw deadlift.

Cement Standards and Concrete Standards. ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and …
Classification and strength tests should be conducted to develop a soils stratigraphy of the subsoil conditions. In general, all laboratory testing should be conducted in accordance with American Society for Testing Materials Standards (ASTM). The tests should include classification and strength tests.
The principal soil type is the (single) component of the soil (i.e. boulders, cobbles, gravel, sand or silt) which is thought to represent (in a coarse soil) the greatest proportion by weight (Table 2.4). Where two types are thought to be equal, two components may be given (for example, sand and gravel, boulders and cobbles). BS 5930:1981 rightly

🕑 Reading time: 1 minute The aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. Fig 1: Aggregates used in production of concrete. The aggregates are broadly classified into two types based on […]
the soil can be tested in place. Procedures for evaluating liquefaction from SPTs are given in Reclamation's Design Standards No. 13, Embankment Dams, "Chapter 13, Seismic Design and Analysis." SPT N data can be used to estimate the shear modulus of clean sands, but the method is approximate. If the shear modulus is needed,
Residual strength of sands. Shear tests on sand indicate that the stress-displacement curve for the loose and dense states are as shown in Fig. 3.41. The residual strength is seen to correspond to the peak strength of the loose density and is usually reached fairly quickly in one travel of the shear box, succeeding reversals having little effect.

ISO 679:2009 specifies a method of determining the compressive and, optionally, the flexural strength of cement mortar containing one part by mass of cement, three parts by mass of ISO standard sand and one half part of water. ISO 679:2009 applies to common cements and to other cements and materials, the standards for which call up this method.

Only the drained strength of sand is normally relevant in practice and typical values of the friction angle for loose sands and dense sands are given in Table 13.3. In the case of dense sands, peak value of in-plane strain can be 4° or 5° higher than the corresponding value obtained by conventional triaxial tests. This increase is negligible ...
Soil is a nonhomogeneous, porous material for which engineering behavior is greatly influenced by density, source material, stress history, and hydrogeology. Some engineering properties (e.g., undrained shear strength in normally consolidated clays) may vary as a predictable function of a stratum dimension (e.g., depth below the top of the ...
Cohesive soil means clay (fine grained soil), or soil with a high clay content, which has cohesive strength. Cohesive soil does not crumble, can be excavated with vertical sideslopes, and is plastic when moist. Cohesive soil is hard to break up when dry, and exhibits significant cohesion when submerged.

CONTROLLED LOW STRENGTH MATERIAL (CLSM) This information bulletin provides a general guideline for using controlled low strength material (CLSM), generally known as slurry in the construction industry, in lieu of soil for backfill. The 2017 Los Angeles Building Code (LABC) allows the use of CLSM for the backfill of excavations under
To analyze the stability of such structures, the shear strength of the sand-gravel mixtures is needed. For this purpose, direct shear tests were carried out on mixtures of Ottawa sand (d 50 = 0.59 mm) and fine gravel (d 50 = 5 mm). The shear strength of the sand and the sand-gravel mixtures was measured under two normal stresses.

Design Standards No. 13: Embankment Dams . strength implies that pore pressures occurring in laboratory tests on the material satisfactorily approximate field pore pressures and, therefore, the shear strength of those materials. Shear strength tests should be performed on specimens compacted to anticipated placement water contents and densities.
The EN specifications list the 0.2% proof strength values, Rp0.2, at temperatures above the room temperature, up to the temperature where time dependent properties govern. Verification of the 0.2% proof strength, 1.0% proof strength, and/or tensile strength at elevated temperature for austenitic steels is subject to agreement.
