# Stone test:
1. 3/4 "Down Size Is OK
2. Well graded whether 60% is 3/4 ", 30% will be 1/2" and 10% singles.
3. Whether the stones are to be broken.
4. The stones will not be broken, the stone will not be broken.
5. Mud should be free-stone.
6. Do not have dead stones.
7. The weight of one cubic foot will be 160 pounds to 170 pounds (73-77 kg).
# Sand test:
1. Shutting sand in the palms of one hand and putting the hand sand in the hand with the fingers of the other hand. If there is sand on the palate of the palate, then the presence of soil can be understood.
2. If a sandwich of 4 percent is filled with glass and 3 percent water is mixed, then if all the sand falls in 30 seconds and there is tender water on it, sand is good.
3. The presence of mud or organic matter can be understood by spraying water on the child's stomach.
4. First, the solution of 3% sodium hydro oxide solution and sand will be mixed in a good form, leaving the site for 24 hours. If the color of the water is yellow in yellow, it is necessary to understand the presence of organic matter in sand.
#cement test:
1. Pind can be made with a fumigation cement but cement is good.
2. If you feel cold in two cement bags, cement is good.
3. Leave a fitter cement in a glass of water and if it sinks then the cement is good.
4. A fist cement should be in the middle of the water, if it is a bit hotter then cement is good.
# Brick test:
1. Good brick 9 1/2 "multiplication 4 1/2" multiplication 2/3 "will be the ideal size, the bends will be sharp and the problem will be the same.
2. Metallic sound will be hit by two bricks each other.
3. If two bricks form the T (T) form, then it will drop from 1.20 meters (48 ") to the flat ground when the bricks are broken, if not broken.
4. It will absorb the highest 15% water of its own weight if it has a brick water.
Let's know what the seatering is and why it is given ???
Another name for sutoring is the Form Work. This is the temporary structure. For the work of concrete it is obligatory. We know that the concrete is in a raw state like mud. Only a certain size comes after the concave blockage. To give this specific shape, the structure of the shape is made accordingly. After this, raw concrete is provided in this structure and the structure is removed after drying or necessary hardening. In such a column, the structure of the column is made by keeping the required flexibility around the rod barrier. After this raw concrete was given inside this papal section. The cost of this savings is 20 to 25 percent of the total cost. Sterling is usually made of wood or steel. But currently the use of steel saaters is more.
Because this saater can be used many times, its water is not absorbed. Again, it has more power to concrete. Not all sizes can be made in wood, but any size can be made with the steel. For example, if you use steel to make round columns. Can not be made with wood.
Good quality of good sutoring
1) Must have enough capacity to load and carry live load.
2) It will be strong enough, so that the actual shape of the structure does not change due to the diffusion.
3) The materials used in the form work should be available and affordable.
4) Formwork on solid foundation must be established.
5) It should be useful to open and use multiple times.
6) There will be no loss of concrete on any type of opening.
7) Formwork joints will be strong enough to ensure that the cement grout does not leak.
8) Both the horizontal and vertical sides will have enough support or restrictions.
9) The thin as well as the better. If the heavier the carry, the problem of working with the saaters will be less and the speed of the work will be reduced.
10) It will be waterproof, so that it can not absorb water from concrete.
11) It can be easily built and removed.
Load Form Workload Load
The formwork carries the following load
1) Newly prepared concrete weight
2) Hydrostatic pressure of newly prepared concrete
3) Workers' weight weights
4) Vibrational Load
5) Impact reaction during the concrete slip in the form
