Monalisa Patel. Advantages: Since shape and size of bricks are uniform, it do not need skilled labour for the construction. It reduce permeability and increase durability of concrete floor. The weight of compared is high compared to its strength. List the main ingredients required for the production of reinforced concrete as a construction material in a conventional RC construction (10 Points). Open-Source Since Concrete5 is open-source, you will have the ability to freely modify and … As a student, you will be required to write many different kinds of essays. We also have both advantages and disadvantages about coaching. 3) Pre-stressed concrete members offer more resistance against shear force. Widely variation can be found from one sample of lean mix and it can be a great confusion to determine the exact result. tensile strength, but there are some drawbacks also of that reinforcement. It is not necessary to provide joints in pre-cast construction. Not only does high strength concrete allow for more applications, it also increases the strength per unit cost, per unit weight, and per unit volume as well. Advantages of Optical Fiber Greater bandwidth & faster speed—Optical fiber cable supports extremely high bandwidth and speed. i. Concrete is considered as a chemically combined mass where the inert material acts as a filler and the binding materials act as a binder. 2. ii.

When reinforced, all types of the structures are made possible from an ordinary lintel to massive fly overs. 2. Concrete makes a building fire-safe due to its noncombustible nature. Advantages of full-wave rectifier: 1. E-learning increases productivity. Low speeds, security and very small user interface. 3. The most important binding materials are cement and lime. Minor interior waterproofing repairs may cost only a few hundred dollars -- for concrete repair or fillers -- but external waterproofing systems cost several thousand dollars due to the need for specialized excavating equipment to reach and repair the foundation footings. Pre-stressed concrete offers more advantages than reinforced concrete, which are as follows; 1) The cross-section is utilized more efficiently in pre-stressed concrete as compared to reinforced concrete. Allowing the angle of attack to be remotely adjusted provides greater control, so the turbine collects the maximum amount of wind energy for the time of day and season. That reinforcement gives concrete strength against its weakness I.e. Construction joints are provided to avoid cracks due to drying shrinkage and moisture-expansion. 1. Reinforced Cement Concrete:- Reinforced concrete, or RCC, is concrete that contains embedded steel bars, plates, or fibers that strengthen the material. Firstly, concrete blocks are ideal for foundations and basement walls because they're stronger than poured concrete. Requires equipment (i.e., a floor machine, wet vac, mop, mop bucket, etc.).
