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

## Concrete Mix ratios and types M5, M10, M15,M20 and M25

Standard Concrete Mix Ratios Concrete at the very least contains 3 materials Cement, Sand and Crushed Stones. The ratio in which you add these determines how strong or weak concrete will be. If you are using concrete for not so demanding projects you may mix concrete in already known commonly used ratios. Below is a… Continue reading Concrete Mix ratios and types M5, M10, M15,M20 and M25
