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 else can I help you with?
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
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.
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 is the substance that slows down or stops a chemical reaction called?
A substance by itself will not slow down a chemical reaction; factors require change, such as cooling the reactants or lowering the concentration, to do so. Adding another chemical or substance that happens to slow a reaction often does so by actually interfering with the reaction and replacing or preventing it outright, and there is not a name for chemicals that do this -?inhibitor?-, since a chemical may do this to one reaction, but be a catalyst to another.Added:decrease surface area/ remove catalyst/ decrease temperature/ decrease concentration/ add inhibitor/ dilute reactants/ separate reactants/
Can you use trisodium citrate as a cement retarder?
Yes, trisodium citrate can be used as a cement retarder. It works by delaying the hydration process of cement, which slows down the setting time. Trisodium citrate is often preferred for its ability to control the setting time of cement mixes effectively.

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 non opaque substance slows down light the most?
In a vacuum, light travels at its maximum speed. When passing through a non-opaque substance, such as glass or water, the speed of light slows down due to interactions with the atoms in the material. Among common substances, light generally slows down the most in materials with a high refractive index, such as diamond.
How can bacteria diseases be cured?
Yes, An antibacterial is a compound or substance that kills or slows down the growth of bacteria.
What is a substance that slows down or stops a chemical reaction?
An inhibitor is a substance that slows down or stops a chemical reaction by interfering with the reaction process. This can be achieved by binding to the reactants, blocking active sites on enzymes, or changing the pH of the environment to make the reaction less favorable.
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.
What substance slows down the body process?
Alcohol is a substance that can slow down the body's processes, including reaction time, coordination, and cognitive function. It can also depress the central nervous system, leading to symptoms like drowsiness and decreased heart rate.
Does cooling speed up the motion of the particles?
No, cooling actually slows down the motion of particles. When a substance is cooled, the particles lose kinetic energy, which leads to a decrease in their speed of motion.
How does cold liquid affect the rate at which a substance dissolves?
Colder temperatures make molecules move more slowly. Since molecules are moving more slowly, they are less likely to 'bump' into each other and interact. When you are trying to dissolve a substance, you want as many interactions as possible between the substance you want to dissolve and the liquid you are trying to dissolve it in. Since the cold temperature slows down the rate of these interactions, it slows down the rate at which a substance dissolves.
