i seriously need advice on what to do after reading the ratio of mixing concrete of pillars which i just saw on this platform ,my bricklayer just used ratio1;4;4 and i saw here that it shd be 1;2;4...it is a storey building which is 13m by 10m with 20 pillars ,so b/4 moving to decking i want to know if the former mix ratio will not ve effect on the building , the foundation was done with y16mm iron rod with over site concrete/german floor and all the blocks were filled with concrete b/4 the german floor.9'' blocks was used for the block works from foundation to lintel. is there anything to be done . a mixing machine was used for the mixing of the concrete of the pillars, pls advice on this ratio1;4;4 used already it is a very dry land

How many people even use 1:2:4?
1:4:4 is majorly use for reinforced concrete works in many private buildings in Nigeria
As long as it was properly mixed & 16mm was used, u have nothing to fear.
You can continue with your 1:2:4 from there

txs and God bless you sir
