  • Compressive strength of M20 concrete cube Test procedure

    Compressive strength of M20 concrete at 14 days: Making of at least 3 concrete cube size each 150mm×150mm×150mm in mould by cement sand andIt was predicted that compressive strength of concrete would reduce up to 15% when 50% RIS and 50% RCA were utilized in concrete and 115% when natural aggregate was fully replaced by RIS and RCAFlexural strength of M15, M20 and M25 grade concrete

  • How much cement sand & aggregate required for M20 concrete

    Ans :19 cft (042 m3, 680 kgs) sand are required for 1 cubic metre of M20 concrete How much aggregate required for M20 concrete We have given dry volume of concrete is equal to 154 cubic metre and part of aggregate in concrete mix is equal to 3/55, density of aggregate is equal to 1550 Kg/m3 and one cubic metre is equal to 353147 cu ftAnswer (1 of 4): This is 65% of the characteristics strength In case of M20, 7th day strength shall be : 20*065=13 N/Sqmm Got it now? Thank you for the A2A Best wishesWhat is the compressive strength of grade 20 concrete at

  • Concrete Mix Design Calculation M20, M25, M30

    If the coarse aggregate is not angular, the volume of coarse aggregate may be required to be increased suitably, based on experience Note 2: For pumpable concrete or congested reinforcement the coarse aggregate proportion may be reduced up to 10% Hence, Volume of coarse aggregate per unit volume of total aggregate = 062 x 90% = 0558 VolumeCoarse aggregate: It consist of 12 mm and 20mm crushed aggregate and the specific gravity is 275 crushing load is noted to calculate crushing strength of concrete according to IS: 5161959 The measuring strength of A FOR M20 GRADE OF CONCRETE: SNO SNo Compressive Strength of Cube (N/mm2) CTM StrengthRH UPV 1 246 22 237 2 257 24INTERPRETATION OF COMPRESSIVE STRENGTH IN

  • An Analysis over Partial Replacement of Coarse Aggregate

    mechanical properties of M20 grade concrete integrate waste tyre as coarse aggregate The compressive strength was tested by using universal testing machine (UTM) for the cube specimens The specimens were cast with M20 grade concrete using 0%, 5%, 10%, 15%, 20% and 25% partial replacement of waste tyre as coarse aggregateHence, to prepare 1 cubic meter of M20, M15 and M10 concrete, 157 cubic meters of “total dry volume” of cement, sand and aggregate are needed, whereas to prepare 1 cubic meter of M75 and M5 concrete, 152 cubic meters of “total dry volume” of cement, sand and aggregate are needed Many websites are giving different values for the “total dry volume” of the ingredientsCalculate Cement Sand & Aggregate M20, M15, M10,

  • EXPERIMENTAL STUDY ON STRENGTH CHARACTERISTICS OF

    the fine aggregate and coarse aggregate is less the obtained concrete is lighter in weight Cubes, beams and cylinders were casted by partial replacing natural coarse aggregate by 25%, 30%, 35%, 40%, 45% and 50% of manufactured fly ash aggregate and using quarry as fine aggregate The strength parameters such as compressive
