This is method is ignorant of how cement works. I just listened to an audiobook called Stuff Matters by Mark Miadownik about the material science behind all the common materials that make our modern worldpaper concrete steel etc. and in it the author explained that concrete doesnt dry when it hardens it actually cures in a reaction with water such that it incorporates water at a .
2020-7-25The proportions of cement sand coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete. So care should be taken while calculating the amount of Cement Sand and Aggregate required for 1 Cubic meter of Concrete. Method-1 DLBD method to determine material requirement for 1 Cum concrete The DLBD Dry Loose
2020-7-20With concrete being one of the most useful building materials there are countless applications for its use on-farm. The most common uses of concrete are for shed floors and footings bunkers post footings and stockyards. While the process of laying concrete can be expensive there are several options for those wishing to carry out the work themselves and save money.

2020-7-26Cement 1 x 1500 1500. Sand 1.5 x 1700 2550. Coarse aggregate 3 x 1650 4950. Therefore the ratio of masses of these materials w.r.t. cement will as follows 1 1.7 3.3. The water cement ratio 0.45. Now we will calculate the volume of concrete that can be produced with one bag of cement i.e. 50 kg cement for the mass .
2020-7-26in my country one bag of cement is 50kg or 0.035cum and for measuring aggregates and sand we use head pans0.0175cum. for 1cum of concrete the expected materials are cement 6.5bags sand 0.44cum26headpans aggregate0 0.8851headpahs.but on site we have to use more material to achieve the expected volume instead of the estimated calculations .
2020-7-25Void Ratio If you fill the shuttering area with blue metal alone it has lots of voids in it which also need to be filled by the other materials such as sand cement. Such void gap is known as void ratio compressibility which is 20 for coarse aggregate. So if we need 1 m3 of concrete in wet condition we have to take consideration of the .
Take Sand content as percentage of total aggregates 36. Select Water Cement Ratio 0.43 for concrete grade M35 From Fig 2. of I.S. 10262- 1982 Select Water Content 172 Kg From IS 10262 for 20 mm nominal size of aggregates Maximum Water Content 186 Kg M 3 Hence Cement Content 172 0.43 400 Kg M 3

Importance of Gravel and Sand for Concrete Hunker. nbsp 0183 32 Concrete is made up of cement and water plus an aggregate composed of sand and gravel The sand and gravel do more than act as filler though The size and amount of gravel added to a bag of concrete also determines the product s volume strength and durability
