how much sand and cement to lay 1000 bricks , if someone gets this right I will be gratful as I have heard so many different suggestions and I have my own idea

You probably need around half meter of sand, best get a ton in a hippo bag, which i believe is between 1/2 and 1 meter. cement id use a 4/1 mix. if i remember correctly 40 bags make a ton, so around 10 bags should be ok. that's a guess anyway. Iv laid 400 bricks with just over .25(quater) meter of of sand. lets see what the pro's say.

About a tonne of mortar per 1000, plus or minus a bit depending whether the briccks are frogged (one big dent), pierced (3 holes) or perforated, (lots of small holes).

You can work it out: Brick joint is approx 225 x 10mm underneath + 75 x 10mm for one perp end, brick is 100mm wide. So: (0.225 + 0.075)x 0.1 X 0.01 X 1000 = 0.30 cubic metres for 1000 bricks. This allows for no frogs or perforations and allows for no waste, these factors can double the mortar needed. So on average you'll need 0.6 cubic metres of sand (1 tonne) + 6 to 8 bags of cement (depending on mix strength)

From my surveying days I recall that for a 1/2 brick wall you will need 0.03m3 mortar per 1m2 and for a one brick wall 0.07m3 60brick in 1m2 of 1/2 bw 120 in 1m2 1BW 1000/60=16.67 m2 so 16.67x0.03 = 0.5m3 for 1/2BW 1000/120=8.33m2 so 8.33x0.07 = 0.58m3 for 1/2BW assume the sand volume is equal to the mortar volume as water and cement will fill the voids between the grains of sand. so 1/2BW needs 0.5m3 or 0.8tonne sand 1BW needs 0.6m3 or 1.0tonne sand Cement will depend on the mix you are after Jason

As the idiot who mixes for our happy band, the standard 4:1 morta r mix for bricks is 10 bags cement per Tonne sand. 6:1 for footings concrete is 6 bags cement per tonne ballast.

thanks for the replies it would appear jason and the clever man are right it was the figure I had worked out but just wanted to check to make sure , just a note to the rest we order in m3 down here as a tonne of sand will vary if its wet ,
