Introduction

How materials behave is dependent on various factors, some of which include their mechanical properties. When the material experiences various loading conditions, its behavior reflects its mechanical conditions as well as the effect of the loading conditions. When a material experiences various loading conditions, the material experiences either shear stress, tensile strength, or compressive strength. The tensile properties of a material relate to its ability support any axial loads to which it is subjected without rapturing (Department of Engineering. 2007). When a material is subjected to tensile stress, the deformation that occurs is in the form of elongation or ...

Abstract

Materials exhibit different chemical and mechanical properties such as strength and durability. Combining different materials to form a material composite enhances their individual properties in different measures. In this experiment, the mechanical strength of composite sandwich structures was investigated through bending. Four samples were investigated for their properties on bending and strength. Three of the four polystyrene beams were reinforced with paper while the fourth beam was investigated without paper reinforcement. One of the beams was bonded with construction paper on one side; the next bema was bonded with construction paper on both sides while the third beam was ...

Business managers in Nigeria lack understanding of the business development process needed for successful growth in quarry in Akamkpa, Nigeria.

Requirements for the Degree of Prescott Valley, Arizona

Introduction

A quarry is like an open pit mine from where minerals are extracted that are mostly used in the construction of buildings and civil engineering works. Quarrying is a part of mining but is slightly different as it has a close connection with the society because different builder of a region requires material that is extracted in order to complete their work. There are not many restrictions for quarrying as it is open for all the contractors. Due to this reason all the managers and developers at different levels need to ...

DEFLECTION OF BEAMSIntroduction

Any kind of modern day construction makes use of a component called structural beam, or beam. A beam helps in adding strength of any design or structure. Generally manufactured using steel, wood, or concrete, it is commonly used for spanning any open element of a structure. In any design work based on iron, steel I beam is the most commonly used one. On the other hand, home-based constructions generally make use of wooden beams. When steel I beam is encased within concrete, it forms a concrete beam and is typically used in the construction of heavy structures, such as ...

Introduction

Field density testing is significant for assessing the soil properties of a site identified for a project. The assessment of soil property done through field density testing is aimed a verifying that the soil contained the required properties for the type of project to be constructed at the identified site (Thiers and Donovan 45). This lab uses the Sand Cone Method to verify the compaction of fill material and determine if the soil meet the required compaction with a design unit weight of 2,000 kg/m3. The aim of the experiment was to determine the dry unit weight, to ...

Nurses will continue to play an important role in the health care delivery system. The United States just like any other country across the world is faced with challenges in the delivery of quality healthcare. For instance, an increased in the aging population creates a demand for quality care in the treatment of chronic diseases (Shi & Singh, 2014). To adequately address these challenges, transformation of nursing profession becomes necessary. Health care professionals are needed to take care of the patients in all settings that are; in the hospitals and homes. Caring for the sick is becoming complicated day in ...

Analysis of Oil Palm Shell Concrete-A Review

Many researches have been conducted on to use oil palm shell (OPS) as the light weight material in last three decades. It is an agricultural waste normally generated from palm oil industry. This industry is normally situated in Malaysia, Indonesia, Thailand, and some other countries. There are many products being made from OPS. The use of OPS as lightweight aggregate in making concrete mix is the main project of many companies in different countries including Malaysia that was first introduced by Abdullah in 1984. Malaysia playing an important role in manufacturing of different oil palm products as it gives ...

Abstract

Concrete acts as one of the most essential and cost-effective construction material made from a mixture of sand, cement, aggregates, and water. Cement acts as a binder for holding all the components together. Engineers working in the construction site must understand the purpose of the construction because different structures require different concrete strengths. The strength of cement paste used controls the overall strength of concrete that depends on the water-cement ratio. The following experiment was conducted to investigate different mechanical and physical properties of concrete.

Objective: To determine mechanical properties of concrete.

Materials used: Aggregate (coarse and fine), sand, cement, water, compressive machine, cylindrical and rectangular molds, timer, ...

Lab number/title:

Introduction Purpose of the lab experiment was to gain knowledge about structural properties of wood. In this lab experiment, a species of wood was tested. Four parameters namely Modulus of rupture, compressive strengths parallel to the Grain in longitudinal Orientation as well as perpendicular to the Grain in radial Orientation were found out by carrying out the experiment. Wood is an important construction material for possessing some outstanding structural properties. Application of wood can be seen as a compressive member. Being an anisotropic material, its properties change with direction with respect to wood's grain structure. Engineering properties of this material ...

Classical theory of knowledge or epistemology (the scientifically oriented knowledge) informs part of the important areas in philosophy. It addresses such questions as what is knowledge; from where do we get the knowledge? How are our beliefs justified? How do we perceive the world around us? Do we know anything at all? How do we ascertain that we have the knowledge? How do we quantify the knowledge that we have? What is knowledge? Rene Descartes (rationalist) in his apology to his disciple Plato claimed to be the wisest man in the whole world alive because he knew that ...

Abstract Continuous Flight Augers (CFA) require special expertise to construct but done properly they are economical and very successful for areas with inconsistent load carrying capacities. Examples include using CFA pilings for guard rails, highway reinforcement, highway junction improvements and buildings. The CFA pilings are similar to driven and bored piles but offer different advantages when working in good to marginal soils and in projects where the load capacity needs vary. An auger with a hollow tube is used to bore the hole and then when the auger tip reaches the final depth concrete is added as the auger ...

Sand can be classified into coarse sand and fine sand, based on particle size. The former is usually greater than 4.75 mm (retained in a No. 4 sieve), while the latter is less than 4.75 mm (passing through the No. 4 sieve) (1).The properties, including shape and texture, size gradation, moisture content, specific gravity, reactivity, soundness, and bulk unit weight, of different types of sand,influence concrete strength (2). The shape of sand particlescauses variations in the surface to volume ratio, and a larger surface to volume ratio improves bond characteristics but decreases concrete workability. The surface texture of sand ...
