## BBS of a Slab Bar Bending Schedule Tutorial

Now we are going to learn how to create bbs of a slab, we have previously learnt the bbs of column, footing and beam. We are going to use all the formulae we learnt in the basics of bbs. As you can see from the drawing above there are two kinds of bars in this… Continue reading BBS of a Slab Bar Bending Schedule Tutorial

## Bend Deduction in BBS Bar Bending Schedule

Bend Deduction in BBS Let’s first see what  bend deduction is and how to apply it. When you bend rebar it stretches. When you stretch a 100g loaf of bread, it still weighs 100g, stretching it will increase its length but not weight. So instead of directly multiplying the Unit weight with the length, we… Continue reading Bend Deduction in BBS Bar Bending Schedule

Now we are going to learn how to create bbs of a beam, we have previously learnt the bbs of column and footing. We are going to use all the formulae we learnt in the basics of bbs. As you can see from the drawing above there are two kinds of bars in this beam.… Continue reading BBS of Beam Bar Bending Schedule Tutorial

## BBS of Column Bar Bending Schedule Tutorial

We are going to learn how to create bbs of a column in this article, this is in continuation to our previous article where we learned how to create bbs of a footing.  As you can see from the drawing above there are two kinds of bars in this column. One is long L shaped… Continue reading BBS of Column Bar Bending Schedule Tutorial

## BBS of foundation Bar Bending Schedule Tutorial

We are going to learn how to crate a bar bending schedule bbs of a Foundation. We are going to use all the formulas we learned in How to create a bar bending schedule. I recommend you read the basic article first. If you look at the image you can see that there are essentially… Continue reading BBS of foundation Bar Bending Schedule Tutorial

## M30- Concrete Mix Design Example with Water Reducing Admixture

M30 Concrete Mix example: Let’s say we have to design a Reinforced Concrete Cement(RCC) with a slump of 100 using Cement (Specific Gravity 3.14), 20mm Sub Angular Coarse aggregate (Specific Gravity 2.45) and Zone 2 Sand (Specific Gravity 2.50) for a Moderate exposure condition. Plus We will be using a water reducing admixture SuperPlasticiser 1%… Continue reading M30- Concrete Mix Design Example with Water Reducing Admixture

## M25 -Concrete Mix Design Example

In a previous article we Designed M20 so let’s design M25 in this one. Let’s say we have to design a Reinforced Concrete Cement(RCC) with a slump of 100 using Cement (Specific Gravity 3.14), 20mm Sub Angular Coarse aggregate (Specific Gravity 2.45) and Zone 2 Sand (Specific Gravity 2.50) for a Moderate exposure condition. These… Continue reading M25 -Concrete Mix Design Example

## Concrete Mix Design – M20 Grade of Concrete

Let’s say we have to design a Reinforced Concrete Cement(RCC) with a slump of 100 using Cement (Specific Gravity 3.14), 20mm Angular Coarse aggregate (Specific Gravity 2.45) and Zone 2 Sand (Specific Gravity 2.50) for a Mild exposure condition. These are the steps you will take: STEP 1 : TARGET MEAN STRENGTH For MILD exposure… Continue reading Concrete Mix Design – M20 Grade of Concrete

## 13 Types of Cement and their Uses in Concrete Construction

Main Types of Cement 1. Ordinary Portland Cement(OPC) Ordinary Portland cement is the most widely used type of cement, which is suitable for all general concrete construction. It is the most commonly produced cement around the world.  This cement is suitable for all kinds of concrete construction. 2. Portland Pozzolana Cement(PPC) Portland Pozzolana Cement is… Continue reading 13 Types of Cement and their Uses in Concrete Construction

## Compressive Strength of Concrete, with Cube Test procedure

What is Compressive Strength Compressive strength of concrete is how much load it can take without cracking. In general Construction the compressive strength of concrete varies from 15Pa to 30Pa and higher for commercial and industrial use. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material,… Continue reading Compressive Strength of Concrete, with Cube Test procedure
