What is the length of 4 inch wide cement block?
8 inches
What is the weight of 8 x 8 x 12 cement block?
Cement weighs about 150 punds per cubic foot, and there are 1728 cubic inches in a cubic foot, so if the block is solid then it weighs 150x8x8x12/1728 = 67 pounds

What is the R-value of rigid foam insulation?
The R-value of rigid foam insulation typically ranges from 4 to 8 per inch of thickness, indicating its effectiveness in resisting heat flow.
What cement can i use on the face of the block?
It's called Surface Bonding Cement. It has chopped fiberglass in it. How to use it: Build a footer. Stack the block uo on the footer in the shape of the building. Get the block wet on one side of the wall. Trowel a 1/8" coat of Surface Bonding Cement on that side of the wall. Go to the other side of the wall, wet it and trowel a 1/8" coat of Surface Bonding Cement onto the wall. Keep it damp for the next week so it gets a chance to cure properly. Remember, concrete hardens by chemical reaction, not by drying out.
How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?
Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch
I was building a cement block wall Its 8 inch thick standard hollow block I am going to fill it up with cement and metal rebar plus use fiberglass fiber in it I can't rember after you fill up a block.?
After filling a cinder block with cement and metal rebar, you need to ensure that all voids are filled and the mixture is properly consolidated to ensure structural integrity. Adding fiberglass fibers can help improve crack resistance and overall strength of the wall. Allow the cement to cure properly before applying any additional loads or finishing touches.
What is the R value of attic insulation covered with plywood decking?
Every insulation has a different R value. It ultimately is determined by which insulation you will be using. Now lets do rough estimate. 4" thick, regular fiberglass mat has R-value of 13. Assuming that plywood has the same to half the insulating value of fiberglass, 1/2" plywood would have 1/8 to 1/16 of R-value of that 4" mat. Roughly R-1.6 to R-0.8
What is the ratio of sand and cement to make mortar?
A typical mixture is three of sand to one of cement. Make a small batch first and check the consistency of it. The wetness of the sand has a lot to do with the consistency. For block and brick work, a bit should squeeze out the side but still support the block or brick with about 3/8 inch above the previous row. Then this side excess is scraped off and pointed with a pointing tool.
How many rolls of insulation to cover 8 x 10 shed?
Depends how big insulation rolls are.
