The document provides information on materials and specifications for a concrete mix including cement, sand, silver, and cobalt materials. It lists the unit weight and quantities of cement, sand, silver, and rebar and stirrups needed to make 1 cubic meter of concrete with a unit weight of 2470 kg/m3. It also specifies the dimensions, reinforcement, and cover thickness for concrete sections.
A method of testing soils by pressing a cone of standard dimensions into the soil under a known load and measuring the penetration. (extensive investigation and research in construction site).
The document describes the standard penetration test (SPT) method for determining the bearing capacity of soils. SPT involves driving a split spoon sampler into the soil using a 63.5 kg hammer dropped from a height of 75 cm. The number of blows required to penetrate each 150 mm interval is recorded as the N-value. N-values are corrected for overburden pressure and dilatancy. Bearing capacity is then calculated using corrected N-values, soil properties like internal friction angle, and factors for shape, depth, inclination, and water table location. The SPT provides soil strength data and undisturbed samples needed to determine cohesion and friction angle for bearing capacity calculations.
This document describes the vane shear test procedure used to determine the undrained shear strength of soft clays. Key details include:
- The test involves inserting vanes into an undisturbed clay specimen and rotating them at a uniform rate until failure to measure the undrained shear strength.
- Calculations are done to determine the shear strength from the torque measurement, using the vane diameter and height.
- The test can also measure soil sensitivity by remolding the soil after the initial test and measuring the reduction in strength.
This document describes the standard penetration test (SPT), which is commonly used to evaluate the engineering properties of soils in the field. It discusses the equipment used, including the drilling rig, split spoon sampler, drive weight assembly, and cathead. It outlines the procedures for drilling a borehole, driving the sampler, and handling the recovered soil sample. Corrections are applied to account for factors like overburden pressure and dilatancy. SPT N-values can be used to estimate properties like relative density, friction angle, and unconfined compressive strength. The test provides representative samples and index properties but has limitations for some soil types.
The document discusses various field and laboratory testing methods for geotechnical investigations. It describes common in-situ tests like the Standard Penetration Test (SPT), Cone Penetration Test (CPT), Dynamic Cone Penetration Test (DCPT), Vane Shear Test (VST), Dilatometer Test (DMT), and Pressuremeter Test (PMT). It also discusses procedures, components, interpretations and limitations of these tests. The document then briefly covers rock testing methods like Unconfined Compression Test, Brazilian Test, Point Load Test, and Schmidt Rebound Hardness Test.
This document summarizes research on how drilling variables affect fracture-like breakouts in boreholes drilled through sandstone. The research objectives were to determine how variables like stress magnitudes, drill bit type, size, flow rate, and mud weight influence breakout characteristics. Experiments drilling into two reservoir sandstones found that breakout length correlated with maximum principal stress but was also affected by variables like bit type, size, flow rate, and mud weight. With knowledge of drilling conditions, breakout dimensions could potentially be used to estimate in situ stress magnitudes.
1) Foundations can be either shallow or deep, with shallow foundations having a depth less than their width and deep foundations having a depth greater than 3 meters.
2) Before construction, soil must be tested to determine its bearing capacity and strength.
3) Standard penetration tests involve drilling a hole, lowering a split-barrel sampler attached to rods, and recording the blow count as the sampler is driven into the soil in three successive 0.15 meter increments.

This document describes the components and procedure of a static cone penetration test. It details the specifications of the Dutch cone used to measure tip resistance, including its base area, apex angle, diameter, and heights. It also describes the cylindrical sleeve used to measure frictional resistance, noting its area and height. The procedure involves pushing the cone into the ground at a rate of 10 mm/sec, then withdrawing the cone and pushing the sleeve onto the cone to drive them together. Results are recorded in a CPT log. Advantages include speed, economy, and detailed data collection while disadvantages are the inability to obtain soil samples and depth limitations.
The document summarizes the standard penetration test (SPT), a common in situ geotechnical testing method. It describes the basic procedure, which involves driving a split spoon sampler into subsurface soils using a hammer, and recording the number of blows required for each increment of penetration. Corrections are made to SPT values to account for overburden pressure and dilatancy. Empirical correlations are presented relating SPT values to properties like density, shear strength, and consistency of cohesionless and cohesive soils. Both advantages like being inexpensive and quick, and limitations like lack of precision are discussed.
The document summarizes information about the cone penetration test (CPT), a method used to determine geotechnical engineering properties of soils. It provides a brief history of the CPT, describing how it has evolved from a mechanical cone in the 1930s to electric cones in the 1960s. It then explains that the CPT involves pushing a cone tip into the ground to continuously measure resistance, and describes the components of the CPT device and how the test is conducted. Finally, it outlines the advantages and disadvantages of the CPT and how the results can be used to evaluate soil types, densities, and shear strengths for foundation design purposes.
Determination grain size distribution of soilSumanHaldar8
This document describes procedures for determining the grain size distribution of soils through sieve analysis and sedimentation tests. It explains that soils can be classified as coarse-grained if particles are larger than 75 micrometers, and fine-grained if smaller. Sieve analysis involves shaking soils through a series of sieves to separate grains by size, while sedimentation tests use pipette or hydrometer methods for fine soils. The results characterize the soil type, gradation, and engineering properties.
1. The standard penetration test (SPT) involves driving a split-spoon sampler into the ground using a 63.5 kg hammer dropped from a height of 0.76 m. The number of blows required to drive the sampler over two intervals of 150 mm each is recorded as the SPT N-value.
2. The SPT N-value provides an approximate measure of soil resistance and a disturbed soil sample. It can be used to estimate soil strength parameters and bearing capacity through empirical correlations.
3. However, the SPT is highly dependent on the equipment and operator used, as factors like hammer efficiency, drill rod length, and borehole diameter can affect the N-value. Corrections are required

Standard Penetration Test & Liquid Limit,Plasticity Limitgurjapsinghsomal
This document describes the procedure for conducting a standard penetration test (SPT). The SPT is commonly used to determine the properties of cohesionless soils that cannot be easily sampled. It involves driving a split spoon sampler into the ground using a 63.5 kg hammer dropped from a height of 0.75 m. The number of blows required to drive the sampler each 150 mm provides the standard penetration resistance value (N), which can indicate the relative density, shear strength, and compressibility of the soil. Corrections may be applied to N for certain soil types.
The document provides an overview of cone penetrometer testing (CPT), a method to characterize subsurface soils and geology. CPT involves pushing a cone tip instrumented to measure resistance through the ground to create a log of soil properties. Measurements including tip resistance, sleeve friction, pore pressure, and temperature are used to interpret soil type, stratigraphy, strength, and groundwater levels. The document cautions that CPT logs need to be "ground-truthed" by comparing to samples to accurately interpret thin, weak layers like landslide surfaces. Sample CPT logs are attached to demonstrate the measurement data.
This document discusses site investigation techniques using in situ testing. It describes penetration tests like the standard penetration test (SPT) and cone penetration test (CPT) which measure penetration resistance. It also discusses strength and compressibility tests like the field vane shear test and pressure meter test. Finally, it discusses permeability tests like rising/falling head tests and constant head tests. The document focuses on the SPT, providing details on the procedure, equipment used, and corrections that must be applied to raw SPT N-values to account for overburden pressure, hammer energy, borehole diameter, and other factors.

This document describes a project to improve water yields for villages in Tanzania through rainwater harvesting and artificial groundwater recharge. A 1989 water scheme was experiencing declining yields, so from 2006-2014 monitoring and pilots were conducted. A strategy of increasing groundwater recharge through rainwater infiltration was tested. A hillside dam and infiltration pits successfully recharged an estimated 2.5 million liters, increasing dry season yields from 0.3 to 0.8 liters/second. Proper maintenance and community involvement were important to the project's sustainability. While challenges remain, the results demonstrate that rainwater harvesting can significantly improve rural water supplies.

Abstract
Free online information can be beneficial in the preparation, design and implementation of rural water projects. Free online sources of meteorological data (rainfall, evaporation), maps (topography, geology), aerial imagery and elevation data are presented together with examples of how this information has been used in rural water projects. This online information can never fully substitute field observations and measurements, but it can provide valuable additional information and make preparation, design and implementation of rural water projects more efficient and successful.

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.

This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.
zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

• VES was done using
wenner method.
• Augering was also done
at two sites: Results-
Point A; 0-1.5m (course
sand), 1.5-1.9 m (clay)
and 1.9-2 m (fine sand).
Point B; 0-1 m (sand), 1-
1.5 m (sand and rocky
pieces).
• With wenner;

4. Subsurface composition…
From wenner indicates
• 0-1.5 m probably sand (confirmed by auger).
• 1.5 – 5 m probably clay (confirmed by auger).
• 5 m – 25 m probably gravel or weathered
rocks.
• No sign of hard rock up-to 25 m depth.
Site not feasible for sand dam construction
since hard rock is deep.
5. How to use the tools
Hydrogeological profiling; to determine
gradient, river banks, rock outcrops, bends,
infiltration (silt)
VES; soil stratification, depth soil strata,
presence of aquifer
HES/profiling; soil strata homogeneity
Auger; soil strata in shallow depths

Editor's Notes
Key; Sand apparent resistivity is not more or is equal to 200 ohms
Hard rock app res is more than 1000 ohms
Clay app res is between 1-50 ohms
