The number of 9-inch blocks a bag of cement can lay depends on various factors, including the size of the block, the mortar joint thickness, and the specific application. Generally, a standard 94-pound bag of cement can lay about 50 to 60 blocks, assuming a typical mortar joint thickness. However, this can vary based on the mix ratio and the skill of the mason. It's best to consult specific project guidelines for more accurate estimates.
Turn the feet into inches then divide by 8 for the height and 16 for the lenth. EXAMPLE - 24ft long times 12 inches = 288 in. divided by 16 = 18 block long. 8ft high times 12 inches = 96 in. divided by 8 = 12 block high. The typical cinder or concrete block in the US is 15-5/8 long x 7-5/8 tall, with a mortor joint of 3/8 in. its measures 16 in. x 8 in. Dont forget your interior walls where bearing is needed. With wood beams these are needed every 16ft. With metal, the sky is the limit, although the steel beams must be built per size. Also there are many different size thicknees, the typical is 8 in. so the block will be a 8x8x16 in block. They also comes in 4 in. in this case the block is a 4x8x16. 12 inches is a foot but keep in mind that 16 inches is a linear foot.
There are different sizes of brick. You will need to know how many bricks are in a square foot, including the mortar joint.
To determine the number of bricks required for a 700 square foot area, you'll need to consider the size of the bricks and the thickness of the mortar joint. A standard brick size is approximately 7.5 inches long, 3.5 inches wide, and 2.25 inches tall. Assuming a typical coverage of about 7 bricks per square foot (including mortar), you would need approximately 4,900 bricks for a 700 square foot area. However, it's advisable to account for waste and breakage, so ordering an additional 10% is recommended.
The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.

Use a masonary bit. If you are able to fasten at the mortar joint, it drills easier.
most common block size is 8"x8"x16". Actually, the block is 3/8" shorter in all dimensions to allow for the mortar joint.

The number of 8-inch blocks that can be laid with a 90-pound bag of mortar mix depends on the thickness of the mortar joint and the specific block size. Generally, a 90-pound bag of mortar can lay about 30 to 35 standard 8-inch blocks with 3/8-inch joints. To get a more accurate estimate, consider the specific dimensions and joint thickness used in your project.
8"x8"x16"but the blocks themselves actually measure 7 1/2x 15 1/2 (+/-)to allow for the mortar joint.
A construction joint in concrete jobs is a joint where a fully set and hard concrete joins a fresh concrete to make a joint. Normally, cracks would occur at this joint because concrete was not cast monolithic. A contraction joint is joint between two concrete edges so formed which allows minute movement between the two edges caused by heat or some other external forces. Usually, contraction joints are also referred to as expansion joints.

A paper joint in concrete is a type of control joint that is created by placing a strip of paper or other compressible material in the concrete before it hardens. This helps to control cracking caused by shrinkage and movement within the concrete slab. The paper joint allows the slab to crack along a predetermined line, reducing the chances of random cracking.
A cold joint keyway is a type of construction joint used in concrete work. It is created by stopping the pouring of concrete at a specific location and then continuing later. Keyways are created by using a special tool or construction joint form to shape the concrete for proper bonding when the second pour occurs.
A shrinkage joint, or control joint is a separation cut with a finishing handtool into wet concrete sidewalks to 1/4 of the depth of the concrete. Since concrete shrinks a tiny bit as it cures, little tiny cracks may develop . . . the shrinkage joints make those cracks appear in the nice straight joints, thus improving the looks of the new concrete walk. Shrinkage joints may also be cut in after the concrete has cured long enough to stand on (several hours) with a concrete-cutting saw.
