to mix 1 cubic meter of cement at a ratio of 3:1 how many 20kg of sand and 25kg bags of cement will be needed? we have now cut down to 1/2 a cubic metre apparently.The consensus for 1/2 a cube seems to be, 1 tonne sand, 14 bags cement.This should give 3:1 by volume! ( use a bucket for easy and accurate measuring.Do not mix it by weight).

a simple guide to concrete cube testing oncrete is one of the most widely used building materials in the world, yet people still find it difficult to take samples correctly and manage the testing & certification process.Failure to do this can result in the need to spend even more money.
ok, so i've got 2 concrete slabs to lay, one is 5.4m and the other is 5m x 5m, both 4" thick.How much concrete will i need, i get it to around 3 cube per room.Q2 this is the killer, because of where i'm doing this we can't get a premix in so it's got to be done by hand so how much sand, stone and cement am i gonna need.
Thus, a 3,600-pound cubic yard contains about 800 pounds of cement, which comes out to 10 of the 80-pound bags of cement or 13.3 of the 60-pound bags.Pure cement, sand and crushed rock all have about the same density, so a block of pure cement measuring 1 cubic yard of volume (about 3,600 pounds) will contain 45 bags of cement.

A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard).The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content.
Mixing concrete by hand.Typically in the uk, concrete is hand mixed 'on the deck' (i.The ground), generally using either a slab of existing concrete or a large mixing board - both of which can easily be hosed down and cleaned off afterwards.
Mixing concrete.When it comes to mixing concrete, there are three options to choose from: mix by hand - where less than m of concrete is needed, it can be mixed by hand by a reasonably fit person.; use a cement mixer - where the quantity is between about m and 2m, a powered concrete mixer is useful or ; buying in ready mix - where more than 2m of concrete is needed, it is easier.
