mix design

What is the maximum strength of concrete that we can design the proportions by using IS 10262 latest version and what is the highest grade of concrete to be used as per IS 456

Hello, After many tests, it seems that ANY combination of hard aggregates in my castings produces holes here and there which I try to prevent as much as possible. what is the best mix ratio from cement/sand ( no hard aggregates) for thin castings such as bowls and planters? I know that...

Standard deviation is a measure of the variation of concrete strength of a set of data from its mean. it is similar to six sigma process where we plot a normal distribution curve to get a better idea about spread and deviation. If the strength results are away from the mean, the deviation...

Concrete mix designing is a vital part of any construction activity. Why we do mix design when proportions for material are listed in IS codes for various grades? The listed mixes have more cement content than required and have fix properties like workability, retention time etc. In order to...

HOW COARSE AGGREGATES AFFECT MIX DESIGN? Coarse Aggregate Properties affecting Mix Design Strength Maximum size of coarse aggregate : Maximum size of aggregate affects the workability and strength of concrete. It also influences the water demand for getting a certain workability and fine...

Important points to be remembered while doing Concrete Mix Designing In order to make a concrete mix design that works, you should master all the concrete theories in combination with experiences of concreting at work. Here is some important things you need to know when design concrete mixes...

If You really Ask me, then let me tell you. The number of cement bags per cum of conrete depends on Your Concrete Mix Design. Mix Designing is done to achieve a specific characteristic of Concrete like compressive strength, durability etc. Characteristic of concrete depends on design of...
