(b) water,
wherein for every 75 kg of pre-mortar mixture, the amount of water added is between 18.5 to 19.5 liters,
wherein the resultant mortar mixture has a specific gravity of 1.55 to 1.63.
2. The mortar mixture of claim 1 consisting of a mixture of:
(a) a pre-mortar mixture consisting of: (i) cement ranging from 37% to 41% by weight; (ii) sand ranging between 59 to 63% by weight; (iii) bentonite ranging between 0.001 and 0.003% by weight; (iv) Hydroxypropyl Methylcellulose (HMPC) ranging between 0.001 and 0.002% by weight; and (v) plaster of Paris ranging between 0.002 and 0.004% by weight; and
(b) water,
wherein for every 75 kg of pre-mortar mixture, the amount of water added is between 18.5 to 19.5 liters,
wherein the resultant mortar mixture has a specific gravity of 1.55 to 1.63.
3. The mortar mixture of claim 1 wherein, the pre-mortar mixture further comprises chemical foam ranging between 0.0005 to 0.0015% by weight, wherein the chemical foam comprises detergent powder.
4. The mortar mixture of claim 2 wherein, the size of nearly 80% of the sand is lesser than 200 microns and greater than or equivalent to 150 microns.
5. The mortar mixture of claim 4 wherein, the size of the rest of the sand is lesser than 600 microns.
6. The mortar mixture of claim 2 having a setting time of up to 5 hours.
7. The mortar mixture of claim 2 wherein, the pre-mortar mixture and water are mixed for a minimum of two minutes leading to the formation thereof.
8. A mortar mixture comprising a mixture of: (a) a pre-mortar mixture comprising: (i) cement ranging from 37% to 41% by weight; (ii) sand ranging between 59 to 63% by weight; (iii) bentonite ranging between 0.001 and 0.003% by weight; (iv) Hydroxypropyl Methylcellulose (HMPC) ranging between 0.001 and 0.002% by weight; and (v) plaster of Paris ranging between 0.002 and 0.004% by weight; and (b) water wherein, the mortar mixture comprises a specific gravity ranging between 1.55 to 1.62.
9. A method for laying tiles comprising: (a) laying a foundation layer of a mortar mixture over a foundation surface; (b) striping the layer with a striper whereby the layer is turned into a striped layer comprising a plurality of elongate parallel ridges; and (c) laying tiles over the striped layer resulting in direct bonding between the tiles and the striped layer over time, wherein said mortar mixture consists of a mixture of:
(a) a pre-mortar mixture consisting of: (i) cement ranging from 37% to 41% by weight; (ii) sand ranging between 59 to 63% by weight; (iii) bentonite ranging between 0.001 and 0.003% by weight; (iv) Hydroxypropyl Methylcellulose (HMPC) ranging between 0.001 and 0.002% by weight; and (v) plaster of Paris ranging between 0.002 and 0.004% by weight; and
(b) water,
wherein for every 75 kg of pre-mortar mixture, the amount of water added is between 18.5 to 19.5 liters,
wherein the resultant mortar mixture has a specific gravity of 1.55 to 1.63.
