Yes, you can. You should clean the dry concrete with water and a brush first, and you should use a bonding agent (available pretty much anywhere you buy concrete) for optimal adhesion. You may also wish to add reinforcement such as rebar.
Concrete is what you make a sidewalk from. To make concrete, you mix Portland cement, sand, gravel (aggregate) and water. The cement holds the aggregate together.
Grout is a material used to fill voids in concrete or tile structure. Grouting or Injection Grouting or Pressure Grouting invariably means the process of injecting grout into isolated pores or voids in a concrete or tile structure.Eg:- Injection grouting in a concrete water storage tank.
It depends on the depth of the water. The hydrostatic pressure increases with depth.
Water/cement ratio law states that the strength of concrete is only dependent upon water/cement ratio provided the mix is workable.Strength of concrete primarily depends upon the strength of cement paste.Similarly, the strength of the paste increases with cement content and decreases with air and water content.
Earth or concrete/steel dams.
Concrete does not float naturally in water; it is denser than water. However, when concrete objects such as boats or platforms float on water, it is typically due to buoyancy provided by a hollow structure or trapped air pockets within the concrete. This buoyant force can make the overall concrete object less dense than water, causing it to float.
The pH of water for making concrete is 6 to 8.The water should be free from organic matters.Sea water should not be used for making concrete.Potable water is used for making concrete.
no, provided there is not a high water table. It can stay empty for 2-3 months
It is not recommended to use salt water to mix concrete as it can cause corrosion of metal reinforcements within the concrete, leading to structural issues over time. It is best to use fresh water for mixing concrete.

Typically, one bag of concrete requires about 2.5 to 3 quarts of water for proper mixing.
You should clean concrete floors with a mixture of warm water and a mild detergent. Scrub the floor with a stiff brush or mop, then rinse thoroughly with clean water. Avoid using harsh chemicals or abrasive cleaners that can damage the concrete.
Because water is a fluid so heat can transfer by convection to the surface of the radiator can be 'radiated' into the room very quickly. Concrete is an aerated solid so can't do this, and is a very poor conductor, so loses its heat a lot more slowly. The concrete bricks are also aerated, and air is an even poorer conductor than concrete.
Food, water, shelter, and space are four key resources provided by a habitat for the organisms living there. These resources support the survival and reproduction of the species within the ecosystem.
The concrete mix should be a 5:1 Cement to water ratio. make sure you mix thoroughly when adding water. Look up "Concrete slump test"
If you want to have overhead water storage tank for small capacity, then you should definitely go for PVC tank.
