How many 25 kg bags of builders sand are required for m3 of brickwork 215 x 102.5 x 65 mm mix 1:5

For cost effectiveness i would buy a ton bag of sand and a mix should really be 1:4 Hope that helps

If your only doing one m2 of Brickwork I would purchase 3 bags of 25kg of building sand , should be more than enough ...hope that helps

As a rule 800kg lays with 6 bags of cement approximately 1000bricks depending on frog depth 10 bricks will be approximately 8kg of sand 60 bricks to a square metre 60 x 8=48kg 2 x 25kg bags =50kg There’s your answer !! 6 bags of cement into a bulk bag of 800kg sand will turn into a ratio of approximately 5:1 depending on your hod carriers shovel sizes.

I've always worked on1kg of building sand to metric brick simple to work out 3 m2 180kg
