👉ኬንያ በ3.6 ቢሊዮን ዶላር ግዙፍ የፍጥነት መንገድ ልትገነባ ነው

ከኬንያ ዋና ከተማ ናይሮቢ ተነስቶ እስከ ሞምባሳ የወደብ ከተማ ለሚገነባው 440 ኪሎ ሜትር ፈጣን መንገድ 3.6 ቢሊዮን ዶላር የገንዘብ ድጋፍ ተገኘ።

የፍጥነት መንገዱ "የኡሳሂሂ የፍጥነት መንገድ" ተብሎ የሚጠራ ሲሆን፣ ግንባታው በ2028 ሲጠናቀቅ በአፍሪካ ረጅሙ የክፍያ መንገድ እንደሚሆን ታውቋል።

"ኡሳሂሂ" የስዋሂሊ ቃል ሲሆን ትርጉሙም "በትክክል ተከናውኗል" ማለት ነው።

በሁለቱ የኬንያ ትላልቅ ከተሞች መካከል ይወስድ የነበረውን ከ10 ሰአት ወደ አራት ተኩል ይቀንሰዋል ተብሏል።

የኬንያ ሀይዌይ ባለስልጣን፦ ከአሜሪካ የመሠረተ ልማት ኢንቨስትመንት ኩባንያ ከሆነው "ኤቨስትሮንግ ካፒታል" ጋር የፈጣን መንገዱን በጋራ ለመገንባት ተስማምቷል።

በጋዜጣዊ መግለጫው፦ የገንዘብ ድጋፍ የሚመጣው ከዓለም አቀፍ ባለሀብቶች፣ ከልማት ኤጀንሲዎች፣ ከጡረታ ፈንድ እና “ከፍተኛ ቁጥር ካላቸው የኬንያ የግል ባለሀብቶች” መሆኑ ተጠቅሷል።

የግሉ ዘርፍ ጥምረቴ የፍጥነት መንገዱን ለ30 ዓመታት በፋይናንስ፣ በመገንባት፣ በማንቀሳቀስ እና በመንከባከብ እንደሚሠራ ታውቋል።

The private-sector consortium will finance, construct, operate and maintain the expressway for 30-years.

የፍጥነት መንገዱ የማረፊያና የዱር አራዊት መመልከቻ ቦታዎች እንዳሉት የታወቀ ሲሆን፣ የአካባቢው ማህበረሰብ በግንባታ ወቅት ጥቅም ላይ የሚውሉ ክህሎቶችን እንዲማር የስልጠና መርሃ ግብር ይዘጋጅላቸዋል ተብሏል።

የኬንያ ፕሬዝዳንት ዊልያም ሩቶ፦ ፕሮጀክቱ ከመንገድም በላይ ግልፅ፣ ዘላቂ እና ማህበረሰብን ያማከለ የልማት መስፈርትን ይከተላል ብለዋል።

የኡሳሂሂ የፍጥነት መንገድ ፕሮጀክት ይፋ የሆነው፦ ሩቶ በቅርቡ በአሜሪካ ያደረጉትን ጉብኝት ተከትሎ የተፈጸመ ነው።

ETCONP SOLUTIONS & ANSWERS


Solution

-> Quantity of Brick 🧱 = L x B x H
= 4 m x 3 m x 0.3 m = 3.6m³

-> Quantity of plastering (wall has
2 faces)
= 2 x 4 m x 3 m = 24m²

Cost of brick 🧱 work 1000 birr/m³
Cost of plastering 200 birr/m²

Cost of 🧱 = 3.6 x 1000 = 3600birr

Cost of plastering = 24 x 200 = 4800birr

👉What is Fibre-reinforced concrete

✳️Fibre-reinforced concrete (FRC) is concrete that has fibrous materials mixed in to increase the concrete's durability and structural integrity.

✳️FRC has small, short, and discreet fibres that are randomly oriented yet uniformly distributed throughout the concrete. The fibres can be circular or flat, and often makeup one to three per cent of the concrete mix's total volume. Common fibres used in reinforced concrete include steel, glass, synthetic, and natural fibres.

🚧Why fibres are used?

✳️On its own, concrete lacks tensile strength and is prone to cracking. But fibre-reinforced concrete can improve tensile strength and control cracking in concrete structures that are often caused by plastic shrinkage and drying shrinkage. Fibres in concrete can also reduce the permeability of concrete, which limits the amount of water that bleeds out, further reducing shrinkage cracking during curing.

📌The necessity of Fiber Reinforced Concrete

⏺1- It increases the tensile strength of the concrete.

⏺2- It reduces the air voids and water voids the inherent porosity of gel.

⏺3- It increases the durability of the concrete.

⏺4- Fibers such as graphite and glass have excellent resistance to creep, while the same is not true for most resins.

❇️Therefore, the orientation and volume of fibres have a significant influence on the creep performance of rebars/tendons.

⏺5- Reinforced concrete itself is a composite material, where the reinforcement acts as the strengthening fibre and the concrete as the matrix. It is therefore imperative that the behaviour under thermal stresses for the two materials be similar so that the differential deformations of concrete and the reinforcement are minimized.

⏺6- It has been recognized that the addition of small, closely spaced and uniformly dispersed fibres to concrete would act as crack arrester and would substantially improve its static and dynamic properties.

☄Types of Fibers

✅1- Steel fibres
✅2- Glass fibres
✅3- Carbon Fibers
✅4- Cellulose Fibers
✅5- Synthetic Fibers
✅6- Natural Fibers

🚧Advantages Of Fibre Reinforced Concrete

⏺1- High modulus of elasticity for effective long-term reinforcement, even in the hardened concrete.
❇️Does not rust nor corrode and requires no minimum cover.

⏺2- Ideal aspect ratio (i.e. the relationship between Fiber diameter and length) which makes them excellent for early-age performance.

⏺3- Easily placed, Cast, Sprayed and less labour intensive than placing rebar.

⏺4- Greater retained toughness in conventional concrete mixes.

⏺5- Higher flexural strength, depending on the addition rate.

⏺6- Can be made into thin sheets or irregular shapes.

⏺7- FRC possesses enough plasticity to go under large deformation once the peak load has been reached.

⏺8- Increased durability and high flexural rigidity.

⏺9- Reduced permeability, bleeding, and formation of microcracks. 10- Minimum weathering effect.

⏺11. Reduces deflection.

⏺12. Minimum corrosion.

🚧Disadvantages Of Fibre Reinforced Concrete

⏺1- Fibres are costly.

⏺2- The fibres should be uniformly distributed in concrete because they may not mix well and form lumps.

⏺3- The size of the coarse aggregate is restricted to 10 mm.

⏺4- Mixing of fibres in large volume could be tedious.

⏺5- Construction with FRC skilled labours.
