What are the different grades of concrete?
Different types of concrete grades and their uses
| Concrete Grade | Mix Ratio (cement : sand : aggregates) | Compressive Strength |
|---|---|---|
| M7.5 | 1 : 4 : 8 | 7.5 MPa |
| M10 | 1 : 3 : 6 | 10 MPa |
| M15 | 1 : 2 : 4 | 15 MPa |
| M20 | 1 : 1.5 : 3 | 20 MPa |
How many concrete classes are there?
Typically, there are twenty-four different types of concrete used in the building and construction industry depending on the type of construction.
What is concrete Class C?
The concrete proportioning is based on developing a concrete compressive strength at 28 days of 4000 pounds per square inch (28.0 MPa) for Class C, 3000 pounds per square inch (21.0 MPa) for Class F and 4500 pounds per square inch (31.0 MPa) for Class S.
What is the highest grade of concrete?
In India maximum grade of concrete used is M60 mostly, and the concrete used above this grade will be designed as self-compacting concrete to ensure compaction.
What are the 4 types of concrete?
The Types of Concrete
- Normal Strength Concrete. This concrete combines all the basic ingredients — concrete, sand and aggregate — using the 1:2:4 ratio.
- Plain or Ordinary Concrete.
- Reinforced Concrete.
- Prestressed Concrete.
- Precast Concrete.
- Lightweight Concrete.
- High-Density Concrete.
- Air-Entrained Concrete.
What is Type D concrete?
Class D concrete is a dense medium strength structural concrete. Class H may be substituted for Class D concrete. Additional requirements for Class D concrete are: An approved water reducing admixture shall be incorporated in the mix. Class D concrete shall be made with 19.0 mm (¾ inch) nominal sized coarse aggregate.
What is Class 2 concrete?
Class 2 is that which will be specified for most good quality architectural precast concrete. A Class 2 finish is intended for external and internal façades that can be viewed in detail.
What are the different types of cement used in construction?
13 Types of Cement and their Uses Ordinary Portland Cement (OPC) Ordinary Portland cement is the most widely used type of cement, which is suitable for all general concrete construction. Portland Pozzolana Cement (PPC) Portland pozzolana cement is prepared by grinding pozzolanic clinker with Portland cement. Rapid Hardening Cement. Quick setting cement. Low Heat Cement.
What is a concrete derived class?
– A concrete derived class is a derived class which implements the all functionality that are missed in the super class. – A derived class is a class that inherits the properties from its super class.
