How does cement dry up?
When water is added it starts a process beginning with the formation of short hexagonal crystals. it is this process of crystal formation which begins the setting process and usually is substantially complete after 24 hours. However, the crystals continue to form and fill up the spaces for weeks and even months as long as the cement is not allowed to dry out. When mixing cement it is recommended to keep it wet for at least 3 days, when it reaches maybe 80% of its final strength, but a week to ten days is better. Cement will continue to harden for several years. The strongest cement you can get is that which sets up underwater and is never allowed to dry out
What is the classification of cement?

What is the importance of performing the experiment to determine the normal consistency of cement?
1. Measure the work-ability of cement. 2. Determining the quality test of cement.
Is cement solid or liquid?
Cement starts off in a semi-liquid state that has the ability to flow. After a while, the cement will cure and harden into a solid. Whether the solit cement is a fluid depends on the kind of cement and how much, as even cement can change shape very slightly. As an example, people who study fluid dynamics also study the movement of the continents and how they interact with one another. Solid rock has the ability to compress and decompress rapidly, causing earthquakes. When dealing with a large quantity of cement, there is an element of fluidity involved.

Why is the name 'Medusa' appropriate for a type of cement?
The name 'Medusa' would be appropriate for a type of cement, because Medusa, in Greek mythology, had the ability to turn people into stone if they looked her in the eyes. I suppose that stone is similar to cement, making it an appropriate name.

I have been eating cement since long time and still i cannot get rid of this habit what happens if you eat cement?
You obviously gain the super amazing ability called intelligence, so you should probably eat more.
Why Portland cement is called hydraulic cement?
Portland Cement is classified as "hydraulic" cement because it cures or solidifies due to its chemical exchange with water, stemming from the building material's ability capability to set under water. In the well industry Portland Cement can be placed or pumped into voids at thousands of feet in depth. As long as the mixture is released or pumped without significant breakdown of the mixture due to water flow the cement will cure just as well we see during ground level applications.
How Much Sand to Cement for Brick Mortar?
The ratio of sand and cement affects the tensile strength of the concrete. Hence, a ratio of 1:2 (cement to sand) will yield a greater tensile strength than a 1:3 ratio. However, both are acceptable in the formation of concrete.
What is the theory for slump test?
Theory: Work-ability is the ease with which the given concrete mix can be mixed together, transported to the application place and can be placed/applied/compacted their within the initial setting time of cement. This property depends largely on the amount of water added i.e. water cement ratio of the concrete mix and kind of aggregates used. Generally work-ability increases with the addition of the water, however it results in the less strength of concrete. So we have to settle for an intermediate value of water cement ratio at which it may have the sufficient work-ability as well as sufficient strength.
