Is it cheaper to build a house out of blocks or wood?
Cinder block homes cost more to build than wood framing. While the price can be as low as 90 cents per cinder block, the average price range is $1 to $3 per block. Additionally, you need to factor in the cost of mortar, rebar, and concrete fill involved in the construction process.

How many bags of cement do I need for 12×12?
of 40lb bag = 1.76 ÷ 0.011 = 160 bags. To determine how many bags of concrete you will need, divide the total cubic yards needed by the yields, at 5 inch thick, for a 12×12 slab you will need 2.22 yards of concrete, so number of 80lb bag of concrete = 2.22 ÷ 0.022 = 100 bags, No.

What is the difference between a cinder block and concrete block?
Cinder blocks are hollow rectangle-shaped structures usually made of concrete and coal cinders which find use in construction sites. Concrete blocks often, on the other hand, are flattened constructs made of steel, wood or cement.
Why are houses built on cinder blocks?
Concrete block houses are energy-efficient, fire-resistant, noise-reducing, pest-resistant, low-maintenance, and healthy. While Concrete houses can cost more to build than wood-frame houses; once constructed, a concrete house quickly recoups the initial costs with lower utility and upkeep costs.
How many 9 inches blocks can a bag of cement Mould?
However, this will never be critical for block moulding based on experience. But in concrete it can be very considerable. Therefore summarily, we need 86 bags of cement and 68 tonnes of sand to mould about 3000 pieces of 9 inches blocks with holes (for 1 bag = 35 blocks).
