The analysis of soil and sedimentary rocks is of great importance for soil chemistry, geochemistry, and ecological research. ...
Custom-designed drilling simulator OU petroleum engineering professor Saeed Salehi and Van Noy have unveiled a custom-designed drilling simulator to help them understand what the rock, heat and pressure environment is like 7 miles down. Salehi and his students will use the rig to test specialized drill bits, pipe and other equipment to determine what materials ...
The New York Power Authority is launching a project with the Electric Power Research Institute (EPRI) to explore the use of crushed rock thermal energy storage to provide reliable and effective energy storage in a market with significant renewable energy resources. ...
Pacific Gas and Electric Company (PG&E) announced today that it has been named one of the nation's three most sustainable large utilities by Target Rock Advisors, and has also been included in Target Rock's 2013 Sustainable Utility Leaders Index (SULI). ...
The objective of the investigation should be to identify and locate, both horizontally and vertically, significant soil and rock types and groundwater conditions present within a given site area and to establish the ...
This practice is dependent on existing data and the currently accepted practice for measurement of drill rod energy ratio, ERi, Test Method D4633 and of the penetration resistance test, Test Method D1586. ...
However, this test method may be followed when testing most soil types if care is taken to ensure that problem soils receive special consideration when tested and when test results are evaluated. 1.6 There are certain limitations inherent in using cyclic ...
Therefore, this test method is not suitable for applications involving grade increases, such as embankment construction or placement of access berms alongside drainage ditches. ...
This test method determines cement content in mixtures of cement with soil or aggregate by chemical analysis. ...
The test methods are as follows 1.4.1 Test Method AThis test method requires the application of a constant cyclic load to the test specimen. It is used for determining the Young's modulus and damping under a constant load condition. 1.4.2 Test ...
The test method may be used for quality control and acceptance testing of compacted soil and soil aggregate mixtures as used in construction and also for research and development. ...
1. Scope 1.1 This test method covers hydraulic conductivity compatibility testing of saturated soils in the laboratory with aqueous solutions that may alter hydraulic conductivity (for example, waste related liquids) using a flexible-wall permeameter. ...
This test method provides a rapid test for evaluation of the quality of a new aggregate source. Research has indicated it may also be suitable for use instead of the sodium sulfate soundness test for evaluating the durability characteristics of fine aggregate for use in portland-cement concrete, thereby ...
The results obtained from this test method can be used to determine the unit weight of compacted dense bituminous mixtures and in conjunction with Test Method D3203, to obtain percent air voids. ...
Note 2—Notwithstanding the statements on precision and bias contained in this test method: The precision of this test method is dependent on the competence of the personnel performing it and the suitability of the equipment and facilities used. Agencies which meet the ...
This test method evaluates RECPs and their means of installation to 5.1.1 Reduce soil loss and sediment concentrations in stormwater runoff under conditions of varying rainfall intensity and soil type, and; 5.1.2 Improve water quality exiting the area disturbed by earthwork activity by reducing suspended solids. ...
This test method is intended to give a relatively rapid indication of the potential expansive reactivity of certain carbonate rocks that may be used as concrete aggregates. ...
Although the P-wave velocity is a good indicator of the type of soil or rock, it is not a unique indicator. Table 1 shows that each type of sediment or rock has a wide range of seismic velocities, and many of these ranges overlap. ...
In areas where the top of rock is weathered or highly fractured, top of rock may be difficult to determine. ...
The recovery of ore in mining operations involves the removal of waste rock, which is stockpiled in large unsaturated piles. When exposed to oxygen sulfide, minerals in the waste rock oxidize, potentially resulting in the generation of acidic leachate, which can be detrimental to aquatic environments. ...
