This document provides an overview of corrosion and methods to prevent or control corrosion. It discusses the high costs of corrosion for replacement and maintenance of structures like bridges and equipment. It also notes safety risks from premature failures. The document outlines six areas of understanding needed to address corrosion problems: corrosion mechanisms, material properties, fabrication/installation, prevention/control methods, testing techniques, and monitoring. It previews the book's coverage of various materials for construction and linings/coatings to resist corrosion in different applications like tanks, pipelines, and processing vessels. The goal is to provide information to design and maintain infrastructure and prevent unnecessary material loss from corrosion.
There is a perception that Pegasystems PRPC can be used to create BPMN-compliant process models. However, I consider this perception to be incorrect.

The document discusses slurry infiltrated fiber concrete (SIFCON). SIFCON has higher strength than ordinary fiber reinforced concrete due to the cement slurry infiltrating the steel fibers. Tests were conducted on SIFCON specimens including compressive strength, split tensile, impact, and flexural strength tests. The results showed that increasing the aspect ratio of the fibers increased the strength, with maximum strength achieved with a ratio of 120. However, SIFCON has some demerits including higher cost and not being suitable for hydraulic structures. In conclusion, SIFCON strength was reduced by 3-7% after alternate wetting and drying, making it unsuitable and uneconomical for those applications.

Fibre reinforced concrete is a composite material made of cement, mortar or concrete with small, closely spaced fibres added to increase tensile strength and crack resistance. The document discusses factors that affect fibre reinforced concrete properties like fibre-matrix stiffness, fibre volume, fibre aspect ratio, fibre orientation, workability, aggregate size and mixing. It also describes different types of fibre reinforced concrete including steel, polypropylene and glass fibre reinforced concrete and their applications in construction.
Shotcrete can be used to seal surfaces, preserve ground strength, support individual blocks, and form structural arches. It acts as a barrier to water movement and seals weak or expanding clays. By sealing surfaces and providing continuous support, shotcrete minimizes ground loosening and smoothes surface contours to preserve ground strength. It also acts as a simple bridge of support between individual blocks. Shotcrete thus provides various functions to stabilize underground structures through sealing, strengthening, and supporting excavated grounds and installed structures.
The document provides information about ready-mix concrete (RMC), including:
1. It discusses the key raw materials used to produce RMC - aggregates (obtained from quarries), cement, fly ash, additives/admixtures, and water. Tests conducted on aggregates and their purposes are outlined.
2. Fly ash is described as a supplementary cementitious material (SCM) that contributes to hardened concrete properties through hydraulic or pozzolanic activity.
3. Additives are chemicals that can improve hardened concrete durability or reduce water content to shorten setting times.
4. The amount of water controls many fresh and hardened concrete properties like workability, strength, permeability, durability
This document discusses different types of special concretes, including fibre reinforced concrete, self-compacting concrete, polymer concrete, high performance concrete, and sulphur concrete. It focuses on fibre reinforced concrete and self-compacting concrete, providing details on their composition, production, properties, and applications. Fibre reinforced concrete is made stronger and tougher through the addition of fibres like steel, glass, and carbon. Self-compacting concrete is able to flow and consolidate under its own weight without vibration, bringing construction benefits like faster placement and improved surface finish.
This document discusses high-strength concrete (HSC). It defines HSC as concrete with a 28-day compressive strength of over 40 MPa. HSC uses a low water-cement ratio, smaller aggregate sizes, and admixtures like silica fume and superplasticizers. Compared to normal-strength concrete, HSC has higher resistance to pressure, modulus of elasticity, and strength gained at an earlier age. Some applications of HSC mentioned include bridges, high-rise buildings, power plants, and skyscrapers. The document concludes that interest in HSC is growing rapidly due to its advantages like reduced material needs and increased construction speeds.
The document discusses competency models and their uses in human resource management. It provides definitions of competencies and examples of how competency models can be applied to different HR functions like development, career planning, performance evaluation, and recruiting. It also outlines California's process for creating a competency model for managers and supervisors that will integrate competencies into the state's HR systems.
The document discusses ferrocement, which is a type of reinforced concrete using closely spaced layers of mesh or small rods encapsulated in mortar. Ferrocement consists of a cement mortar mix reinforced with steel mesh or fiber-reinforced polymer meshes and steel rods. It has several advantages over reinforced concrete including high strength, stiffness, impact resistance, and ability to withstand large deformations. Ferrocement can be used for applications such as tanks, floors, waterproofing, manhole covers, buildings, pipes, bridges, and strengthening existing concrete structures. It is applied using hand plastering, semi-mechanized processes, centrifuging, or guniting.
Shotcrete is a concrete or mortar conveyed through a hose and pneumatically projected at high velocity onto a backing surface. It was invented in the early 1900s and has emerged as the preferred industry term to describe pneumatically applied concrete. There are two main processes - dry mix and wet mix. Dry mix involves pre-blended dry or semi-damp materials conveyed via air to the nozzle, while wet mix fully mixes all ingredients before projection. Shotcrete provides benefits over conventional concrete like density, homogeneity, strength, and ability to apply to any surface. It is widely used for rehabilitation of subway tunnels, domed roofs, highway culvert repair, and new concrete construction.
This document discusses different types of light weight concrete, including light weight aggregate concrete, aerated concrete, and no-fines concrete. Light weight concrete has lower density than normal concrete, ranging from 300-1850 kg/m3 compared to 2200-2600 kg/m3. It has advantages like reduced dead load, improved workability, and applications in pre-stressed concrete and high-rise buildings. The main methods to produce light weight concrete are using porous aggregates, incorporating air bubbles, or omitting fine aggregates. Properties depend on the type and density, with compressive strengths ranging from 0.3-40 MPa.
This document defines and describes lightweight concrete. It discusses three main types of lightweight concrete: porous concrete, concrete without fine aggregate, and lightweight aggregate concrete.
Porous concrete contains air bubbles that make it lightweight. Concrete without fine aggregate uses only cement, water, and coarse aggregates. Lightweight aggregate concrete uses lightweight aggregates like pumice or expanded clay instead of regular aggregates.
The document outlines the characteristics and advantages of lightweight concrete, including better thermal and fire insulation, durability in various environments, lower water absorption, and acoustic properties. It also notes some disadvantages like increased sensitivity to water content and difficulty in placement and finishing.

The document provides information on ready-mix concrete (RMC), including its introduction and history in India, advantages, disadvantages, mixing processes, and uses of admixtures. Some key points:
- RMC was first used in India in the 1950s for dam construction projects.
- It involves weighing ingredients at a central plant and delivering fresh concrete to sites within the requisite time. This provides consistency and reduces waste.
- However, longer transport times can be an issue, and access for trucks must be considered. Concrete must also be placed within 2 hours of mixing.
- Mixing can be done in transit, at the central plant, or on-site for more remote locations. Proper mixing is important
Ferrocement is a thin reinforced concrete made of wire mesh and cement mortar. It was introduced in 1943 and offers high strength and flexibility compared to conventional concrete. Ferrocement consists of thin layers of wire mesh embedded in and covered by a sand-cement mortar mix, with a typical ratio of 5% wire mesh to 95% mortar. It can be formed into various shapes by hand or machine and has applications in construction, agriculture, transportation and more due to its strength, versatility and affordability.
corrosion and protection of steel reinforced c...Emad Behdad

Corrosion of steel reinforcement in concrete is an electrochemical process that occurs when oxygen, water and chlorides penetrate the concrete and reach the steel. It results in rust formation which expands and cracks the concrete. Chlorides from deicing salts or seawater and carbonation are the primary causes of corrosion. Methods to prevent corrosion include using epoxy-coated rebar, thermally sprayed zinc or aluminum coatings, fly ash concrete, cathodic protection systems, and corrosion inhibitors. Titanium mesh anodes can provide cathodic protection without needing power sources.
This presentation discusses the mix design procedure for ready mix concrete. It begins with an introduction to ready mix concrete, including its history. It then discusses the materials used - aggregates, cement, admixtures and fly ash. The equipment, mixing processes, specifications from customers, and quality checks are also outlined. Finally, the benefits of ready mix concrete are noted as consistent quality, strength, and reduced human error due to mechanization.

3. In quel tempo Ges¨´
disse ai suoi
discepoli: ?Nessuno
pu¨° servire due
padroni, perch¨¦ o
odier¨¤ l¡¯uno e amer¨¤
l¡¯altro, oppure si
affezioner¨¤ all¡¯uno e
disprezzer¨¤ l¡¯altro.
Non potete servire
Dio e la ricchezza.
4. Perci¨° io vi dico: non
preoccupatevi per
la vostra vita,
di quello che
mangerete o berrete,
n¨¦ per il vostro
corpo, di quello che
indosserete; la vita
non vale forse pi¨´
del cibo e il corpo
pi¨´ del vestito?
5. Guardate gli uccelli del
cielo: non s¨¦minano e
non mietono, n¨¦
raccolgono nei granai;
eppure il Padre vostro
celeste li nutre. Non
valete forse pi¨´ di
loro? E chi di voi, per
quanto si preoccupi,
pu¨° allungare anche di
poco la propria vita?
6. E per il vestito,
perch¨¦ vi
preoccupate?
Osservate come
crescono i gigli del
campo: non faticano
e non filano. Eppure
io vi dico che neanche
Salomone, con tutta
la sua gloria, vestiva
come uno di loro.
7. Ora, se Dio veste cos¨¬
l¡¯erba del campo, che
oggi c¡¯¨¨ e domani si
getta nel forno, non
far¨¤ molto di pi¨´ per
voi, gente di poca fede?
Non preoccupatevi
dunque dicendo: ¡°Che
cosa mangeremo? Che
cosa berremo? Che
cosa indosseremo?¡±.
8. Di tutte queste cose
vanno in cerca i
pagani. Il Padre vostro
celeste, infatti, sa che
ne avete bisogno.
Cercate invece,
anzitutto, il regno di
Dio e la sua giustizia,
e tutte queste cose
vi saranno date
in aggiunta.
