You may only have two ideas about what concrete is: it’s a material used to build roads, houses, walls, and other solid structures, and you’re going to leave a footprint if you step on a wet one.
You probably learned the second one the hard way. But, did you also know that concrete is actually a mixture of multiple of components, such as cement, coarse rock, fine sand, water, fly ash, and chemical admixtures?
Now, that’s a lot of ingredients just to build one sticky liquid, right?
To learn more about this material, Sci-Denver.com shares some surprising facts about everything concrete.
There is a Ton of Cement Type for Each Use
Categorically, cement is broken down into eight types. Each type has a different property created for a particular use.
- Type I – normal cement
- Type IA – air-entraining cement
- Type II – sulfate resisting cement
- Type IIA – sulfate resisting and air-entraining cement
- Type III – high early cement
- Type IIIA – high early and air-entraining cement
- Type IV – low heat hydration cement
- Type V – high sulfate resisting cement
The Cement-Water Ratios Decide Everything
The lower water content ratio allows a sturdier cement formation, better bonds, and resistance to wear and tear. The higher water ratio, on the other hand, weakens the property of cement.
Some Cement Products Come With an Increased Durability and Flexibility
Not all cement come with the same quality. Engineered and enhanced cement types have higher compressive strength and resistance to weather, making them more sustainable than regular ones.
The Finished or Dried Look of Cement Depends on its Fly Ash Mix
As an added mineral, fly ash provides a finer consistency to the cement because of its round particles. When this particle mixes with the other cement components, it overrides the expected quality of coarse cement with its own.
Other Chemical Admixtures Can Drastically Change the Cement Properties
Chemical mixes can do more than just increase the fineness and quality of cement. They are also applicable for the following:
- Corrects water-cement ratio
- Accelerates concrete setting time
- Slows setting process
- Raises resistance to temperatures
Everyday things always look normal. From time to time, it’s great to know about different things and how they influence everyday life.
