Aug 28, 2012· From thegraph, one can see it forms a hyperbola shape. Aswatertocement ratiois increasing itscompressive strengthis gradually lacking behind.WatertoCement RatioFormulas. Duff Abrams in 1919 presented an equation that relatesstrengthofconcretewithwatertocement ratio. Where; W/c is thewatertocement ratioin theconcretemix.
Example, having 0.4water-cement ratiogives 5600 psi (pound-force per square inches) or 394 kg/cm 2 (Kilogram-force per square centimeter)compressive strengthwhereas 0.7water/cement ratioreducescompressive strengthup to 1067 psi or 75 kg/cm 2 or even less provided allow other factors are …

Get PriceMay 28, 2010· By Adam D. Neuwald. Two of the most commonly specified requirements forconcreteused in the manufacturedconcreteproducts industry are the designcompressive strength(f’ c) and the maximumwater-to-cement ratio(w/c).These two values are inversely related, which means that as thewater-to-cement ratioincreases, thecompressive strengthdecreases.
Get PriceIn the present contribution, thewater-cement-densityratiolaw for the standard curing 28-daycompressive strengthofcement-based materials including grout, normalconcrete, ceramsiteconcrete, and foamedconcreteis proposed. The standard curing 28-daycompressive strengthof different grouts, normalconcrete, ceramsiteconcrete, and foamedconcretewas tested.
Get PriceMar 31, 2019· For these reasons, results fromcompressive strengthtests are more typically used when describing thestrengthofconcrete, as these numbers are more reliable. Additional factors. Other factors contributing to thestrengthofconcreteinclude:Water/cementitiousratio(w/cm) This refers to theratioofwatertocementin theconcretemixture.

Get PriceLoss ofcompressive strength. One m3 ofconcreteis, as a rule, made up of 400-450 kg ofcement. For simplicity’s sake, let’s say we have 425 kg/m3 and awater/cement ratioof 0.45. That means that in one m3 ofconcrete, we have: 425 kgcement;Water: 425 kgcementx 0.45 kgwater/kgcement= 191.25 kgwater…
Get PriceWhat isWater Cement Ratio?Water Cement Ratiomeans theratiobetween the weight ofwaterto the weight ofcementused inconcretemix. Normallywater cement ratiofalls under 0.4 to 0.6 as per IS Code 10262 (2009) for nominal mix (M10, M15 …. M25) We all know thatwater cement ratiowill directly affect thestrengthofconcrete.
