Gypsum slows down the setting of cement.
Although the terms cement and concrete often are used interchangeably, cement is actually an ingredient of concrete. Concrete is basically a mixture of aggregates and paste. The aggregates are sand and gravel or crushed stone; the paste is water and portland cement. Concrete gets stronger as it gets older. Portland cement is not a brand name, but the generic term for the type of cement used in virtually all concrete, just as stainless is a type of steel and sterling a type of silver. Cement comprises from 10 to 15 percent of the concrete mix, by volume. Through a process called hydration, the cement and water harden and bind the aggregates into a rocklike mass. This hardening process continues for years meaning that concrete gets stronger as it gets older.
So, there is no such thing as a cement sidewalk, or a cement mixer; the proper terms are concrete sidewalk and concrete mixer.

What is the name of substance that slows reaction?
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Why does a reaction slow down the time?
Usually:decreasing concentrationlowering the temperaturesometimes lowering pressureremoving any catalyst
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
What slows down the rate of cell division?
Cold slows down cell division.
What type of substance slows down the body's functions and reactions?
Depressors, such as weed, morphine, and heroin are usually the ones that slow down the nervous system.

What substance slows down the body process?
There is no one single, "body process", rather, the body has thousands of processes that go on simultaniously, which means that there is no single substance that slows down the entire body.
What is a substance that slows down or stops a chemical reaction?
an inhibitor
What non opaque substance slows down light the most?
water [No; it's not water.]
What kind of drug slows down the body system?
It is a new substance called Wunga
What type of substance slows down chemical reaction?
Chemical reactions can be either sped up or slowed down by catalysts.
What slows the flow of electrons?
Resistance slows the flow of electrons in a conductor.When you say that a substance has resistance, it actually means that the substance slows down the flow of electrons, thereby reducing the current. So, higher the resistivity of a substance, lesser the velocity of the electrons in the circuit assuming all the other values constant.
How can bacteria diseases be cured?
Yes, An antibacterial is a compound or substance that kills or slows down the growth of bacteria.
Why does a reaction slow down the time?
Usually:decreasing concentrationlowering the temperaturesometimes lowering pressureremoving any catalyst
How does a motions arrangement of particles change as a substance freezes?
The motion slows down, and the arrangement normally packs closer together.
Molecules in a substance slow down when a substance is?
Molecules in a substance slow down when a substance is cooled. Temperature is the measure of average kinetic energy of particles. Kinetic energy is the energy of motion. So when temperature decreases, the average kinetic energy decreases, so the energy of motion decreases, and the molecule slows down.
What slows down the large intestine?
peristalsis slows down the large intestante
