Standard deviation is a measure of the variation of concrete strength of a set of data from its mean.
If the strength results are away from the mean, the deviation will be higher and vice a versa.
Its a statistical measure for Re-designing the mix base on results achieved.
In initial mix...
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...
