Is Alkaline Water Good?

These days we have heard many claims about the alkaline water and its health benefits. Many companies market their product saying it can help in maintaining your body pH level, have anti-ageing properties and prevent chronic disease like cancer.   But is alkaline water is good for your health?  Let's find out.

What is Alkaline Water?
Alkaline water is referred to as water having a pH value greater than 7. Alkaline water typically has a pH between 8-9. pH value is a measure of acidity or basicity of the substance. Pure water free from any kind of impurities has a pH value of 7. Many promoters believe that alkalinity in water can help in neutralizing the excess amount of acid in the body and increase the metabolism rate.

What is Body pH and How it is Regulated?
The normal range for pH in your body is between 7.35-7.45 so, very slightly alkaline. At times, this balance can be disrupted by our diet and lifestyle.

pH can go up or down and this is caused by many factors however when this do…

Water for Construction

Water is an important element for life. It is required in almost every process and operation. In construction quality of water plays  an important role, either it is used in concrete or cement mortar or curing.Many times we have seen that in spite of using best material in cement, required results are not achieved. Most of us think that there is something wrong in cement, but we do not consider quality of water being used.

Using bad quality water in construction  may result to:
a) Loosening of  wall
b) Reduction in compressive strength
c) Dampness persistently
d) Surface efflorescence
e) Corrosion in steel bars

As per IS:456-2000 standards there are listed some checks/tests which one should perform before using the water for construction purposes:

1) pH: The pH values of water shall generally be not less than 6 and not more than 8.

2) Acidity Limit: It should not require more than 5ml of 0.02 normal NaOH to neutralize 100ml sample of water, using phenolphthalein as an indicator.

3) Alkalinity l…
