Grade of ConcreteGrade of Concrete is the classification of concrete according to its compressive strength For making concrete we use cement, sand, aggregate, and water which are mixed with certain ratio and concrete is cast and put in a cube of 150 mm size and put in a water bath for 28 days and afterward, it is tested in a compression test...know more

CEMENT CONCRETE MIX DESIGNFACTORS TO BE CONSIDERED FOR MIX DESIGN The grade designation giving the characteristic strength requirement of concrete The type of cement influences the rate of development of compressive strength of concrete Maximum nominal size of aggregates to be used in concrete may be as large as possible within the limits prescribed by IS 456:2000...know more

Compressive Strength of Concrete CubesAccording to Wikipedia, Compressive Strength of concrete is defined as the Characteristic strength of 150mm size concrete cubes tested at 28 days Why do we test at 7, 14 & 28 days? Concrete is a macro content with Sand, Cement, & Coarse aggregate as its micro-ingredient (Mix Ratio) and gains its strength over time at the hardened state...know more

GRADE OF CONCRETEThe strength measure with concrete cube or cylinders by civil engineers at the construction site Cube or cylinders make during casting of the structural member and after hardening, its cure for 28 days Then the compressive strength test conducted to find the strength Regular grades of concrete are M15, M20,...know more

Partial Replacement of EAn experimental study is made on the utilization of E-waste particles as fine and coarse aggregates in concrete with a percentage replacement ranging from 0%, 20% to 30% ie (0%, 10%, 20% and 30%) on the strength criteria of M20 Concrete Compressive strength, Tensile strength and Flexural strength Concrete with and without E- waste plastic as ....know more

Concrete Mix Design CalculationConcrete Mix Design Calculation for M20, M25, M30 Concrete with Procedure & Example Concrete mix design is the process of finding right proportions of cement, sand and aggregates for concrete to achieve target strength in structur...know more

AggregatesCoarse aggregates are any particles greater than 019 inch, but generally range between 3/8 and 15 inches in diameter Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed...know more

Compressive Strength of ConcreteCompressive strength of concrete cube test provides an idea about all the characteristics of concrete By this single test one judge that whether Concreting has been done properly or not Concrete compressive strength for general construction varies from 15 MPa (2200 psi) to 30 MPa (4400 psi) and higher in commercial and industrial structur...know more
