Is glue a polymer?
Yes, glue is a polymer.
If you add water to a polymer what will happen?
When water is added to a polymer, it can cause the polymer chains to swell and increase in volume. This is because water molecules can interact with the polymer chains, promoting their separation and expansion. In some cases, this can lead to the polymer absorbing water and becoming softer or more flexible.
Is DNA polymer or monomer?
DNA is a polymer
Why glycerine a polymer?
Glycerin is not a polymer because it is a simple compound, not a chain of repeating units like a typical polymer. Glycerin is a triol compound that does not exhibit the characteristics of a polymer structure.
Arrange the following in order from size from smallest to largest polymer monomer carbon atom macromolecule?
Carbon atom, Monomer, Polymer, Macromolecule
How can I make moldable concrete?
To make moldable concrete, mix concrete with a polymer additive that increases its flexibility and workability. This allows the concrete to be shaped and molded into various forms before it hardens.
What is High density polymer concrete?
What is Polymer concrete?It is also known as resin concrete because synthetic resins are used instead of cement in its manufacturing.Density of cement concreteDensity of normal concrete is in the order of about 2400 kg per cubic metre. The density of light-weight concrete will be less than 1900 kg per cubic metre.To call the concrete, as high density concrete, it must have unit weight ranging from about 3360 kg per cubic metre to 3840 kg per cubic metre, which is about 50% higher than the unit weight of conventional concrete. They can, however be produced with the densities upto 5280 kg per cubic metre using iron as both fine and coarse aggregate.The high density concrete is used in the construction of radiation shields.Density of polymer concreteNormally, the density of polymer concrete is not more than 2260 kg per cubic metre, when you use normal aggregates like granite stone chips and river sand as you do in standard cement concrete.When you use aggregates obtained from iron ore or iron rod pieces, you can make high density polymer concrete upto 5140 kg per cubic metre.
Why although concrete components are elastic concrete is inelastic?
Well this is not quite true. Aggregate is a key component of concrete and is inelastic. In addition concrete pillars and beams will bend slightly under load and is thus not 100% inelastic. Polymer modified concrete and rebar modified concrete is also slightly elastic.

What is a 'dry polymer'?
A dry polymer is one that is not in solution. they are used where moisture would create an issue. Sometimes dry polymer powder is added to cement so that when the cement is hydrated to make concrete, the dry polymer is hydrated at the same time. If a wet polymer, or polymer solution were used, it would react with the cement and make it unusable.

What is the best concrete patch material to use for repairing cracks in a driveway?
The best concrete patch material for repairing cracks in a driveway is a polymer-modified cement-based patching compound. This type of material is specifically designed to adhere well to existing concrete surfaces and provide long-lasting durability.
What are the best methods for repairing concrete cracks, and how effective is concrete crack filler in addressing this issue?
The best methods for repairing concrete cracks include using epoxy injections, polymer-based fillers, or cementitious patching materials. Concrete crack fillers can be effective in addressing small cracks, but may not provide a long-term solution for larger or structural cracks.
Is a diamond a polymer?
polymer
How durable is kool deck compared to concrete for instance?
I have seen Kool-Deck by Mortex last over 20 years if done properly. Kool-Deck only works on brand new concrete as it is applied the same day the concrete is poured and MUST be done by an experienced installer. If the concrete is already there then use one of the polymer modified "spraydecks." "Preferred" is a good brand to use. Spraydecks are not as cool as Kool Deck but at least it works on existing concrete.
Is lipid a polymer?
A lipid is both a polymer and monomer. Polymer: Triglyceride Monomers: glycerol and fatty acids
Is a sunflower a reaction or a polymer?
polymer
