Concrete Mix Design As Per IS 10262-2009 With Example



Concrete Mix Design or Mix Design of Concrete is a procedure of determining the relative quantities and proportions of different ingredients of the concrete i.e. Cement, Water, Fine Aggregate, Coarse Aggregate, with the object of producing homogeneous fully compactable concrete having required Strength and Properties with economy.
Now a Days with the advancement of concrete technology, the mix design of concrete is in a boom due to the requirements of High Grades of Concretes having required amount of workability, durability and other properties but the main factor is that these all things are achieved by mix design also with economy, that is there is nothing more in quantities of any ingredients of concrete than that required for producing particular type of concrete grade. Nominal Mixes can be adopted only upto the grade of M20, but above m20 grade, a concrete must be mix designed as per code provisions. Though most of us uses Nominal mix of 1:1:2 for M25 Grade, but it shouldn’t be done. There are various methods of concrete mix design, some of them are as follows :-

Home Made Waterproofing Compound

Today I’m here going to discuss about how to make waterproofing compound by self at the site during the construction with cheaply available materials. I know it has been a long time since my last article, and maybe you, who are following Techno Genome regularly know the reason behind that, anyways let us concentrate on today’s topic. First of all we have to understand what a Waterproofing Compound is, and why it is required in a Civil Engineering Construction works.
Waterproofing, Water Proofing Compounds, Waterproofing Methods
ENTRANCE OF WATER IN BUILDING

Brickwor Quality Control

Here I’ve listed the most important factors which are to be taken care of while doing Brickwork of any nature structural brickwork or face lifting works in brickwork for better appearance. These points mentioned below should always be taken care strictly in the site of construction for achieving a long lasting durable structure.

Septic Tank Design Easily 5 Minutes

Septic System Design or Septic Tanks Design can be done in various process, but most of them are critical and time taking laborious process. Here in this article I have given tutorial on how to design Septic Tank Easily within 5 minutes and Determine Septic Tank Size. Here I will also discuss some about the general Septic Tank Construction for designing of septic tank successfully you have to follow the steps given below one by one

Step 1: Calculation of Numbers of User : 


In any septic system design this is a very very important step as it will determine the total capacity of the septic tank required.This is the total numbers of user who will be using the septic tank within a single day. For the calculation purpose we must consider the maximum practical numbers of user who may use the W.C. within a day. The calculation can be done very easily, like suppose there is a 4 storied building and having two families on each floor. And each family contains on an average of 5 person. Therefore the building is accommodating (2 x 4) = 8 families and again 8 families will equal to users of (8 x 5) = 40 Nos. Users. Generally in no case user number is kept less than 20 users. Therefore here we will design a septic tank for 40 Users

Design Of Steel Beam Fastest Method With Example

Civil Engineering is vast field from Culverts to Dam , Buildings To Steel Bridges, so as so the Civil Engineering Materials, It includes Steel, Concrete, Timber, Aluminium, Glass etc. Steel Design is much easier in most of the cases than RCC Design in Structural Engineering. Civil Engineering Broadly has three main phase namely Planning – consisting of Drawing, Estimating etc. Structural Design consisting of Analysis of Structures and Design Of Structures and last of all Execution which means erecting the actual work according to the Planning and Designing. Structural Engineering has always been a field of respect amongst all the Civil Engineers. Today I will discuss about a part of Structural Engineering which will be dedicated toward the Design of Steel Beam specifically Steel I Beam. After reading this article you will be able to design a steel beam by your own without any problem. To make the explanation easy for understanding I will elaborate a simple yet considerably good problem which will cover all your needs as far as the Civil Engineering and Structural Design is concerned. I know now a days all the Structural Engineering Analysis and Design is being done by Computer Software like STAAD Pro, Ansys and all that, but without having the knowledge of manual Design of civil and structural engineering all those are useless because you will be not able to understand the Design Data and the outcome from the software.
But before going to start You need to understand few things which I should tell you first or at the later stage you may find some problem.

Top 5 Concrete Problems Turning Catastrophic

The Top 5 Constructional Mistakes and Concrete Problems which can bring disastrous results if ignored are not the huge ones but very common in every construction work, which gets out of the notice of the Engineer-In-Charge in most of the cases. As I feel most of the bad construction takes places not due to the unwillingness of the Engineers, but mostly due to the lack of awareness about those small things which they take lightly and thinks they are of no major importance and will not affect the ultimate construction. I do partially agree with them to the fact that it will not harm the ultimate construction. But How long? How long that improperly made structure be durable and sustainable to the causes of failures? Though this constructional errors may not hamper it all or partially the structure in short run, say about for 10 to 15 years after the construction but in the long run it will cost a massive amount for its restoration due to the degradation through which it will undergo in the future. No one of us like You and me would like to construct a permanent structure which only lasts for 15 years safely, do we? So for assuring the safety to the structure, its durability to withstand all probable condition in future and for preventing the costly restoration works we must take care strictly to the following things, which in general larger part of us don’t really bother about. Here I will discuss about those Top mighty mistakes and their consequences if not corrected at the time of occurring.
