  • Properties of Concrete every civil engineer must know

    Apr 08, 2018· A good concrete should not fall under less than 5% of desired concrete strength. that means, We know that M20 grade concrete has a compressive strength of 20N/mm 2. A good concrete should not show less than 19N/mm 2 (5%) of compressive strength when tested with UTM after 28days. For more information about Concrete Grades can be found here
