The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.
by using the universal testing machine, you can get the actual max load needed to fracture the hollow block and by using the formula, Compressive strength =load(lb)/Areaofcrosssection(in2) u can get the psi rating..

The dry joint is hollow block work is called a mortar joint. After the blocks are stacked, they are filled with concrete.
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.

No, hollow block is not a physical change. A physical change refers to changes in the state or appearance of a substance without altering its chemical composition. However, hollow block is a building material made from a mixture of cement, sand, and other aggregates, which undergoes a chemical change (hydration) during the curing process.

The mass of the cement block can be calculated using the formula F = ma, where F is the force, m is the mass, and a is the acceleration. Given: F = 200 N, a = 5 m/s^2. Rearranging the formula to solve for mass, we get m = F / a = 200 N / 5 m/s^2 = 40 kg. Therefore, the mass of the cement block is 40 kg.
The creation of a hollow block is a physical change because it involves a change in the block's appearance and structure without altering its chemical composition.

In India, there are standards for both hollow and solid concrete blocks. Standards include types of cement to be used and other materials added to the materials.
