What is the cost of cement mortar in floor tile paving?

Tile paving before the general floor or ground leveling, that is, with cement mortar first paved a layer of substrate, to be hardened and then paste the tile with cement mortar. Leveling layer generally with 1:3 cement mortar (volume ratio), the thickness is generally 2 centimeters. For example: construction area 100m2, need 100m2 * 0.02m (thickness) = 2m3 of cement mortar, taking into account the loss of 1%, the actual use of 2.02m3 of cement mortar. 1:3 cement mortar (volume ratio) is converted into weight ratio: 1m3 cement mortar with cement 404Kg, with medium (coarse) sand 1508Kg. The bonding layer is generally used 1:1 cement mortar (volume ratio), the thickness of 0.5 centimeters. The thickness is 0.5cm. Similarly, 1% loss should be taken into account during construction. 1:1 cement mortar (volume ratio) converted into weight ratio: 1m3 cement mortar with cement 758Kg, with medium (coarse) sand 943Kg. According to the above analysis, we can calculate the amount of two kinds of cement mortar in accordance with the laying area of the floor tiles, and then converted into the amount of cement and medium (coarse) sand. With the amount of cement and sand (coarse), multiplied by their local market prices (including transportation costs), you can calculate the cost of cement mortar. The above method, for reference.
