Why is only concrete used for construction but not only cement?

👉 Why is only concrete used for construction but not only cement?

Understanding the fundamental differences of cement and concrete is important. Cement is an ingredient in concrete, and concrete is the finished product used in building foundations, driveways, roads, homes, and the infrastructure around you.[0]

Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials.

  • Concrete Hardens at Ambient Temperature. Concrete sets, hardens, gain its strength at regular room temperature or ambient temperature.
  • Ability to be Cast into Shape. Fresh concrete is flowable and is in liquid state.
  • Energy Efficiency in Production. The amount of energy required for production of concrete is low compared with steel.
  • Excellent Water Resistance Characteristics. Though chemical in water can induce corrosion in concrete and reinforced concrete.
  • High-temperature resistance. Concrete can withstand high temperatures better than wood and steel.
  • Ability to Consume and Recycle Waste. Many industrial wastes can be recycled as a substitute for cement or aggregate.
  • Application in Reinforced Concrete. Concrete has comparable coefficient of thermal expansion to steel.
  • Low or Zero Maintenance Required. Concrete structures do not require coating or painting for regular applications as protection for weathering compared to steel or wooden structures where it is inevitable.
  • Multi-Mode Application. One of the major advantage of concrete is its ability to be used in different application methodologies.
  • Concrete is Economical. Compared to engineered cementitious materials used for construction, the production cost of cement concrete is very low.[1]
        Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. 
                                        In the past limebased cement binders were often used, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or with Portland cement to form Portland cement concrete (named for its visual resemblance to Portland stone).[2]

Design of Structures: Welded Connection

Image
INTRODUCTION The development of welding technology in 1940s has considerably reduced the riveted joint applications. Welding is the method of locally melting the metals (sheets or plates – overlapping or butting) with intensive heating along with a filler metal or without it and allowing cooling them to form a coherent mass, thus creating a joint. A typical weld showing various zones of weld is shown in Fig. 7.1. Such joints can be created to make structures, boilers, pressure vessels, etc. and are more conveniently made in steel. The progress has been made in welding several types of steels, but large structure size may impede the use of automatic techniques and heat treatment which becomes necessary in some cases. Welded ships were made in large size and large number during Second World War and failures of many of them spurted research efforts to make welding a better technology. ADVANTAGES OF WELDED CONNECTIONS The gross sectional area of the welded members is effective since the we

failure of a rivet joints

Rivet Rivets are short ductile and cylindrical bars that are used for making a permanent mechanical joint. The process of forming a riveted joint is called riveting. A rivet is divided into 3 parts i.e., the head at one end, the tapered tail, and shank, The portion between the head and tail as shown in the figure. As it is a permanent joint it cannot be disassembled without the failure of the machine component. The material of rivet should be tough and ductile. They are usually made of low carbon steel, nickel steel, Brass, Aluminum, copper, etc. Physics Behind Rivetting. The main function of a rivet is to make a connection, That has the strength to prevent failure and tightness to prevent leakage. For connecting “> 2 metal plates, firstly holes are punched and reamed. The plates are then separated to remove any burrs or chips. The cylindrical cold or red-hot rivet is then inserted into the hole. Then the head is backed by a hammer or heavy bar and then the Die as shown in the figur

What is Rivet Value? and Efficiency of a rivet joint:-

Image
What is Rivet Value? It is defined as the maximum safe force one rivet can withstand. The strength of a rivet in shearing and bearing is calculated and the lesser value is taken as Rivet value. Beyond this value, the rivet will either fail in shear or will be crushed in bearing. the value of shearing and bearing strength one rivet can be calculated from the following relations:- Note :- Rivet value is least of the equations (i) and (ii) Efficiency of a rivet joint:- The original strength of a structural sheet section is reduced by rivet holes provided in it. The efficiency of a rivet joint is the ratio of the strength of riveted joint to the strength of the solid plate(Ex. strength of solid plate without rivet hole). It is denoted by  ɳ  and is expressed as percentage. The effectiveness of a particular riveted joint is measured by the efficiency. Mathematically efficiency is expressed as:                                                                            ɳ  = Strength of joint
