What are the different road aggregate?
The Different Types Of Aggregate. The categories of aggregates include gravel, sand, recycled concrete, slag, topsoil, ballast, Type 1 MOT, and geosynthetic aggregates (synthetic products commonly used in civil engineering projects used to stabilise terrain).
What are the requirements of a good road aggregate?
Requirements Of A Good Road Aggregate
- Hardness :- A good road aggregate should be sufficiently hard i.e. it should offer maximum possible resistance to abrasion. ...
- Toughness :- A good road aggregate should be quite tough i.e. it should offer the maximum possible resistance to the hammering effect of wheel loads.
What is crushing value of aggregate?
Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
What is crushing strength test?
Compressive strength test, mechanical test measuring the maximum amount of compressive load a material can bear before fracturing. The test piece, usually in the form of a cube, prism, or cylinder, is compressed between the platens of a compression-testing machine by a gradually applied load.
How is crushing strength calculated?
The formula is: CS = F ÷ A, where CS is the compressive strength, F is the force or load at point of failure and A is the initial cross-sectional surface area./span>
What is the crushing strength of concrete?
The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.
What is compressive strength of rock?
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to which withstands loads tending to elongate. In other words, compressive strength resists being pushed together, whereas tensile strength resists tension (being pulled apart).
What is the crushing strength of brick?
(i) Compressive Strength/ crushing strength of first class brick is 105 kg/cm2. (ii) Compressive Strength/crushing strength of 2nd class brick is 70 kg/cm2. (iii) Compressive Strength/crushing strength of common building brick is 35 kg/cm2.

Is 1077 a brick code?
Common burnt clay building bricks (IS: 1077 – 1992) established requirements for general quality, classification, geometry, and physical requirements of burnt clay building bricks which are used in building construction. The type of burnt clay covered in the IS: 1077 – 1992 has a compressive strength of 40MPa or less.
What are the quality of bricks?
Good quality bricks should be well-burnt, as well as having a uniform colour. If bricks are under-burnt or over-burnt, they lose this uniformity. Brick earth – brick earth should be free from physical materials such as stones and pebbles, as well as chemicals like potassium nitrate.
