Hardened cement powder, often referred to as cementitious material or recycled concrete powder, can be crushed and used in some applications, but it doesn't have the same properties as new cement. It may serve as a partial replacement for new cement in concrete mixtures, contributing to sustainability and reducing waste. However, its performance will depend on factors such as particle size, purity, and the specific application. Proper testing and engineering evaluation are essential to ensure it meets the required standards for use.

What is dense phase conveying system?
Dense phase conveying is a term to describe the maximum amount of product that can be moved inside a pipe with the least amount of carrying medium. Typically this is most commonly used in relation to powder forms like cement powder being transferred inside a pipe using compressed air as the fluidizing medium. There is a specific amount of air that can be fed into a powder form that will make the powder flow like water. If you reduce that air amount then compress the powder you can pump it a substantially long way though a pipe with as little as 5% air per volume. Reaching this level is generally known as dense phase transfer.
How much sand and cement will you need to lay 67 2x2 slabs?
To lay 67 2x2 slabs, you typically need a mix of sand and cement for the mortar or concrete. For a standard slab, you might use a 1:3 ratio of cement to sand. Assuming each slab requires around 0.1 cubic meters of concrete, you would need approximately 6.7 cubic meters of concrete total. This translates to about 1.67 cubic meters of cement and 5 cubic meters of sand, though actual requirements can vary based on specific project details and mix ratios.
How do you remove bolt anchors from cement?
Normally you have to cut them off with a grinder. A grinder with a metal cutting blade will allow you to take them down flush with the concrete. Wear eye protection though it does throw lots of sparks and some concrete.
Is asphalt cement primarily made from bituminous coal tar or from petroleum byproduct?
True asphalt cement is made ONLY of petroleum byproduct, and may have varying levels of volatiles still present, but should never include any coal tar, as that is an entirely different binder. The two do have many similarities, though, particularly that they are both thermoplastic binders. But the main answer is that asphalt DOES NOT contain bituminous coal tar.
What is console in c?
Nothing. (You can use this word as identifier though.)
What is in a black hole if you get sucked in?
You are. Though that will not matter because you will be crushed and killed
Why does pita bread get hardened so fast?
It gives off its moisture readily, the reverse of hardened sugar which is hygrocopic (takes on moisture). I thought that hydroscopic could be an acceptable answer, though it's not a 'word'...........
When an aluminum can is crushed did it undergo a physical change or a chemical change?
When a aluminum can is crushed, it undergoes a physical change, because even though the object got crushed and misshaped it still has the same identity.The identity has never changed.
Can you make fire brick using wood ash and water if not then what is the best and cheapest way to make it?
Using wood ash and water is not a good way to make a brick. You can make a brick using cement powder and water. You will need to form this inside of something, though.
Will a mini cooper get crushed by a monster truck or not?
A Mini Cooper will be fully crushed by a monster truck. It will most probably not get stuck in the tires of the large Monster Truck you plan to drive over it, though.
Is asbestos ever found in Portland cement?
Under normal circumstances we would not find asbestos in Portland cement. Asbestos has a number of applications (even though it is hazardous), but none of them involve it being mixed with cement. The presence of asbestos in cement would weaken the final product (concrete, grout, mortar, stucco, or whatever), so there is no reason to deliberately include it in the cement.
Does cement set underwater?
Yes, cement can set underwater, particularly if it is formulated as underwater or marine cement. These types of cement contain additives that help improve their performance in wet conditions, allowing them to bond and harden even when submerged. Standard Portland cement can also set underwater, though it may require specific conditions and techniques to ensure proper curing.
