Grades of Concrete with Proportion (Mix Ratio)
Grades of Concrete with Proportion (Mix Ratio) We use different grades of concrete for different parts of the building. We could say the grade of concrete is the only thing we do care lot while concreting.
A concrete mixer (often colloquially called a cement mixer) is a device that homogeneously combines cement, aggregate such as sand or gravel, and water to form concrete.A typical concrete mixer uses a revolving drum to mix the components.
How to Calculate Water-Cement Ratio in Design of Concrete Mix?
The strength of concrete either increases or decreases, will generally depend upon the w/c ratio. It can also affect the workability of concrete, which is most important to concreting process like mixing, placing and compacting. Therefore it’s most important to calculate water-cement ratio while mix design.
