What is the purpose of mixing water in concrete?

Water is the key ingredient, which when mixed with cement, forms a paste that binds the aggregate together. The water causes the hardening of concrete through a process called hydration.

What is the purpose of adding distilled water?

Companies produce distilled water by boiling water and then condensing the collected steam back into a liquid. This process removes impurities and minerals from the water. Some sources claim that drinking distilled water will help detoxify your body and improve your health.

Which type of water is good for concrete?

In general, water that is fit for human consumption (potable) is acceptable for use as mixing water. However, non-potable sources of water can also be used provided the source does not negatively impact the properties of concrete.

What is the main purpose of cement in concrete?

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together.

Why design mix of concrete is important?

A good concrete mix design creates the foundation of a sound infrastructure. Concrete mix design involves a process of preparation in which a mix of ingredients creates the required strength and durability for the concrete structure. This will ensure the structure will be sound and prevent failure of the mix.

What is the pH of water used in concrete mix?

While the use of potable water is generally safe, water not fit for drinking may also be satisfactorily used in making concrete. As a rule, any water with pH of 6.0 to 8.0 which does not taste saline or brackish is suitable for use.

Why Standard sand is used in mix design of concrete?

The main reason for using standard sand is to eliminate its effect on the reported strength of the mortar cubes. With a standard sand, the only variable will be the cement which you are trying to quantify its properties (assuming the water used is potable water).

How does mixing water affect the properties of concrete?

If the mixing water contains suspended particles in an amount up to 0.02 percent by weight of total water used in concrete, it will not affect the concrete properties. It is found that high content of suspended particles does not affect the strength of the concrete, but affect other properties of the same.

What is the difference between Portland cement and distilled water?

In terms of the difference in the setting times of the Portland cement mixes that consist of proposed mixing water when compared with the use of distilled water. In terms of the concrete strength that is compared with the control specimens that is prepared with the distilled water.

What is the pH value of distilled water for making concrete?

Distilled water is not mendatory but water use for making concrete should be of Ph value 6.5 to 7.5 . Can you convert ocean water into distilled water using a water distiller?

What is the effect of chlorides on the strength of concrete?

This decrease is the strength of concrete compared with that obtained by the concrete using distilled water. The high content of chlorides in water tends to show surface efflorescence, dampness persistently and makes the reinforcement steel prone to corrosion.
