WHY IS M AND SONS sorry caps clsed and wont open

@LittleKachowski I know it increases value and total health points of the structure, but it may also decrease the rate of decay when the building is rented out to a tenant

What is the purpose of mixing higher quality mixes?

i have finished, using only 2 pallets of breeze blocks with 2 and a half left over, using 15 Ltrs of motar, costing 20.98 for the blocks. it costs nothing for the motar if you use what's left over from the other stuff

to add on with the motar, i used 100 Ltrs of prime motar and 3 pallets of bricks (78 left over) replacing all the bricks, will add the cost after i finish the grey bricks

I did the grueling counting for how much total material and cost to replace EVERY No-Fines wall and Concrete floor there is; A total of 2,200 Ltrs of Prime No-Fines, and a total of 3,750 Ltrs of Prime Concrete. -Concrete: 75 bags of Aggregate, 15 Buckets of water, 22.5 bags of cement, and 37.5 bags of sand totaling cost of 156.25 including extras. now for the No-Fines; 30 bags of aggregate, 15 buckets of water, and 5 bags of cement totaling cost of just 26.07 if using the extra concrete from earlier. the grand total being 182.32 Skint!

250 litres for Strong Concrete -
-125 Ltrs Aggregate
-37.5 Ltrs Cement
-62.5 Ltrs Sand
- 25 Ltrs Water (full bucket)

I get 4000psi with this, and follows the guide above exactly - i.e. 1.5 bags cement, 2.5 bags sand, 5 bags aggregate etc.

@JCs4ITnow You just find the percentage of each material used. So for prime mortar, the mixture makes 10L. Sand makes up 75% of the total. So 0.75 x 250L = 187.5L. 0.15 x 250L = 37.5L. Process of elimination gives you 25L of water.

Or even easier for 250L, see the numbers as bags because each container holds 25L. 1 Water means one bucket full. 1.5 cement = 1 and a half bags. 7.5 sand = 7 and a half bags.

so, whose gonna do the math for best mixes for 250 litres? or best for complete full bags?
