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.

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
