Concrete Calculator. The Concrete Calculator estimates the volume and weight of concrete necessary to cover a given area. Purchasing slightly more concrete than the estimated result can reduce the probability of having insufficient concrete. Slabs, Square Footings, or Walls

percentages by weight of cement for M25 and M30 mixes. Concrete mixtures were produced, tested and compared in terms of compressive strength with the conventional concrete. These tests were carried out to evaluate the mechanical properties and compressive strengths .

The above calculation you can use for all Grade of Concrete but just you have to put the different Grade of concrete like M10, M 15, M20, M25 etc. just here with grade of concrete you can change the proportion and the method is just above which I have discuss . Different grades of concrete

restrained to any degree. For example, a concrete pavement resting on a wet subgrade and exposed to drying surface conditions will tend to curl or wa rp upward around the outside edges. This warp is resisted by the weight of the sl ab and also by interlocking features of the joints in the pavement

Accordingly six ready reference curves namely A to F for a wide ..... Specific gravity is defined as the ratio of the weight of solid in a given volume of sample to the weight. More details ...

ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

Compressive Strength of Concrete is an important element in designing R.C.C Structure R.C.C.Structures Compressive Strength of Concrete Consequently Quality of concrete manufactured is often measured by

May 17, 2017018332Concrete Mix design of M5, M7.5, M10, M15, M20, M25, M30 and higher grades of concrete is calculated as below: The procedure for finding the different grades of concrete mixes are same. The below mentioned method can be applied to any grade of concrete by changing the values.

Prestressed concrete is made by casting concrete around steel cables stretched by hydraulic jacks. After the concrete hardens the jacks are released and the cables compress the concrete. Concrete when compressed is the strongest. This type of concrete is used for floors and roofs as well as other things.
