What will be Volume of Concrete for Given Cement Sand and Aggregate Quantity?QuestionCement volume is 0.25m3, Sand volume is 0.25m3, Coarse aggregate volume is 0.5m3. Concrete grade is M25.(mix proportion is 1:1:2). What will be the concrete volume in m3? in progress 0 Concrete Lahiru 4 weeks 2 AnswersSHARE Facebook Twitter Answers ( 2 ) henok tefera Nov 20, 2017 at 17:02Given, M25, mix proportion would be- (1:1:2) VC=0.25m3 VS=0.25m3 Va=0.5m3 Adding the mix ratios=1+1+2 =4 VConcrete=1/4* VC+1/4* VS+2/4* Va =1/4*0.25m3+1/4*0.25m3+2/4*0.5m3 =0.375 m3 Gopal Mishra Nov 21, 2017 at 19:19Volume of fully compacted concrete is given by following formula:where Vc is the volume of concrete. W, C, Fa and Ca are the masses of water, cement, fine aggregates and coarse aggregates respectively.Density of cement = 1500 kg/m3, fine aggregates = 1700 kg/m3 and coarse aggregates = 1650 kg/m3. So, Weight of cement C = 0.25 x 1500 = 375kgWeight of Fine aggregates Fa = 0.25 x 1700 = 425 kgWeight of Coarse aggregates Ca = 0.5 x 1650 = 825 kgConsider w/c ratio as 0.45, so weight of water = 0.45×0.25×1000 = 112.5 L or kgSc, Sfa and Sca are the specific weight of cement, fine aggregates and coarse aggregates which are 3.15 for cement and 2.6 for fine and coarse aggregates.Therefore, putting these values in the formula above, we getVc = (112.5/1000)+(375/(1000×3.15))+(425/(1000×2.6))+(825/(1000×2.6)) = 0.712m3So, Volume of concrete = 0.712m3Leave an answerYou must login or register to add a new answer .Related questionsHow to add Nanosilica to concrete?What is fire rating requirements of a 4 storey building?What Materials can be used as Fine Aggregate Replacement in Concrete?What type of plastic and its thickness is used for curing concrete?How to Mix Design with GGBS in Readymix Concrete?
