Concrete mix design M70 grade of concrete provided here is for reference purpose only Actual site conditions vary and thus this should be adjusted as per the location and other factors Characteristic strength given by the relation 70 165 5 7825 Nmm 2 D Aggregate percent used
The High Strength Concrete is the type of high performance concrete which gives better strength with nominal quantities of the ingredients The HSC is one which gives the compressive strength of concrete at a range of 50MPa and above up to 120MPa The main difference with the nominal concrete is the strength

The present investigation is aimed at developing high strength Self Compacting Concrete of M70 Grade The parameters of study include grade of concrete and effect of size of aggregate The existing Nan Su 2001 method of mix design was based on packing factor for a
This design guide serves to extend the use of concrete beyond Grade 60 in the design of concrete structures using CP65 Hence it is intended for use by engineers familiar with the design of concrete structures using particularly CP65 but who have little or no experience of high strength concrete HSC The guide is intended to provide safe
In the initial phase a high strength concrete beam of grade M70 throughout the cross section was casted and tested Thereafter by replacing the M70 concrete in the middle layer by M20 grade concrete a number of beams were casted with different thickness 100 90 80 60 40 mmThe variation in
Designing high strength concrete HSC Grades M60 and above become a challenges in terms of selecting right proportions of conventional concrete ingredients cementsand and aggregate and necessary inclusions of Chemical admixture one or more and Mineral admixture one or more
In the grade of concretes like M10 M20 M30 etc M stands for Mix of the ratio of cementsand aggregate and 102030 Stands for Compressive Strength Concrete less than M20 grade should not be used in the RCC work as per code IS 4562000 PQC stands for Pavement Quality Concrete Normal grade of concrete a M5 Grade
Apr 10 2020 M55 is used in pier and pressurized concrete girders M60 M70 Grade Of Concrete M60 M70 grades of concrete are used in RCC work where high compressive strength is required such as high rising buildings and long bridges etc
M40 grade stands for its a mix of concrete with a characteristic compressive strength of 40 Nmm 2 The mix design procedure for M40 grade concrete as per ACI Method is discussed Specific gravity of cement 315 Specific gravity of Fine aggregate 265 Specific gravity of coarse aggregate 27 Fineness modulus of fine aggregate 30
Large structures have high strength requirements thus they go for higher grades of concrete such as M30 and above The mix proportions of these concretes are based on mix design Regular Grades of Concrete and their Uses Regular grades of concrete are M15 M20 M25 etc For plain cement concrete works generally M15 is used
Then the compressive strength test conducted to find the strength Regular grades of concrete are M15 M20 M25 etc For plain cement concrete works generally M15 uses For reinforced concrete construction minimum M20 grade of concrete uses Grade of a concrete table
Sep 04 2017 HIGH STRENTH M70 GRADE CONCRETE Page 12 High strength M70 Grade Concrete Concrete is defined as highstrength concrete solely on the basis of its compressivestrength measured at given age Highperformance concrete HPC for concretemixtures possessing high workability high durability and high ultimate strength
The scheme generates 1020 MW of power The spillway glacis was constructed with M50A40 grade with microsilica fume for taking care of possible damages due to abrasion The abrasion loss for mix without micro silica was 557 at 72 hrs while it was 376 for M50 grade concrete and further lower 284 for M70 concrete
Concrete grades are denoted by M10 M20 M30 according to their compressive strength The M denotes Mix design of concrete followed by the compressive strength number in Nmm 2 Mix is the respective ingredient proportions which are Cement Sand Aggregate Or Cement Fine Aggregate Coarse Aggregate
Thanks for A2A Now coming to the question mix design of high strength concrete ie above M40 is influenced by properties of cement sand aggregates watercement achieve high strength it is necessary to use lowest possible watercemen

Grade 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
May 17 2017 Concrete Mix design of M5 M75 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 To make ease in understanding we are finding the Concrete mix design
The present investigation is aimed at developing high strength Self Compacting Concrete of M70 Grade The parameters of study include grade of concrete and effect of size of aggregate The existing Nan Su method of mix design was based on packing factor for a
