  Steel Vs Concrete – Advantages and Disadvantages With features | Hello, guys here we will discuss steel Vs Concrete ie. Difference between steel and concrete so let’s start our journey. 1) Steel Steel is an alloy formed by combining iron and up to 2% of carbon and 1% of other metals or nonmetals. Steel has a specific weight of 7850 kg/m3. It may slightly vary with the composition. Steel is the worlds’ favorite construction material due to its high strength in compression, flexural, and rotation compared to others. The industrial development of the world can be credited to steel. After the mass production of steel started in the 1850s, the industry started to boom. Steel has a high scope as it is used in the needle to the skyscrapers. The major component of steel is iron which is smelted in a furnace and naturally available in the ores. Hematite, magnetite are some examples of ores of iron. Iron is not found in pure form at a natural state. Impurities are removed and other composi...

  Cause, Effect, and Types of Segregation of concrete | What is segregation? A mixture of cement, water, fine and coarse aggregate is called the concrete. In engineering, segregation meanings to “separation of constituent materials in concrete.” So, the segregation of concrete is the tendency of coarse aggregate to separate from the concrete mix. It can generally be observed in the plastic stage of the concrete. Problems like porous layer,  honeycomb , sand streaks, rock pockets, etc. arise due to the segregation of concrete.  Types of segregation Separation of grout (water + cement) from the rest of the particles due to lower specific gravity. Separation of coarse aggregates from the concrete mixture. Separation of water from the concrete mix (bleeding of concrete). Causes of segregation of concrete The difference in the specific gravity of the constituents used in the concrete mix. Vibrating concrete for a long period of time or over the vibration of concrete. Improper ...

  Step by Step- RCC roof Slab steel calculation- Numerical Example In this article, I have described step by step RCC roof Slab steel calculation. So read it carefully one by one to get a clear understanding. Slab is a structural member which enable people to move from one floor and one place to another place in a flat. With out slab one can not take benefit of any structure like, building, culvert, bridge. etc. What is RCC Slab? Simply, the slab in which steel bars are used is known as RCC Slab. The full form of RCC is reinforced concrete cement. Where Reinforcement is called a steel rod. The slab should be strong enough to bear the required load according to design. The slab should be provided steel bars to withheld tensile force, so this slab is called the RCC slab. I have given an example for the calculation of the quantity steel rod in slab below. Let us take an example of a slab. Numecal for RCC roof Slab steel calculation Q) The length and breadth of slab is 10 meter and 7 m...

  In this article I have described about what is PCC, DPC and RCC in civil engineering. These terms are often used in civil engineering. So, I have given some pointwise explanation with their meaning, function and uses. But you have to read carefully to understand it better for practical life in construction. The different between pcc, rcc and dpc are given below:- what is PCC DPC and RCC in civil engineering What is PCC? It stand for Plain concrete cement. This is the mixture of cement, sand , aggregate and water only. Reinforcement is not provided in concrete while construction. It can not be used for column, beam, slab etc which have to bear load or tensile force. It can bear compressive load only so, it can be used for making floor, retaining wall, road etc. What is RCC? It stand for  Reinforcement  concrete cement. This is the mixture if cement, sand , aggregate,water as well as steel rods. It can be used for column, beam, slab etc which have to bear load or compress...

  Estimation is a crucial part of an Engineering. Every civil technician should have a good knowledge of it. The accurate estimation set of procedures is not be followed. Here is the stepwise procedure to calculate the numbers of bricks in the Masonry wall. You can download a .pdf file for calculation of bricks in the wall just by clicking on the top right corner of this article. General Procedure for to calculate bricks in a wall First of all, calculate the volume of the Masonry. (Volume=length x Breadth x Height) Then check for the specification of the brickwork to determine the size of brick and proportion of the mortar and thickness of the mortar joint. Calculated the volume of the individual building units. Also, calculate the volume of the building unit with mortar in it. For instance, if the standard size of brick is 230mmx105mmx55mm and the mortar thickness is 10mm then the volume of the building unit with mortar will be 240mmx115mmx65mm. After that calculate numbers of bui...

  Concrete pavement which is occasionally called rigid pavement is a concrete layer that is in contact with traffics directly and it is used for different purposes and applications. The concrete used for pavements can be modified and changed in various ways as per the requirement. Not only does the concrete pavement need to be strong and durable but also it must be workable and cost effective because it is commonly prone to severe environmental conditions. Concrete pavements offer several advantages which is not possessed by bituminous pavement designs, for example, it is considerably suitable for large points loads, withstand diesel spillage and other aggressive materials, suitable for cases where sub-grade strength is low, resist high temperature, and many more benefits. There are different types of concrete pavement which are employed for various applications and these will be discussed in the following sections.
