       13 . The prefabricated fit in block according to  claim 12  wherein the block being self-locking since each one of the towers is fit in to each one of the inferior segments of the hollow volumes of another block without the use of the mortar mixture. 
   
   
       14 . The prefabricated fit in block according to  claim 12  wherein the block is of light weight. 
   
   
       15 . The prefabricated fit in block according to  claim 12  wherein the blocks are fit in with each other forming the pillars and walls, wherein each one of the towers is fit in to each one of the inferior segments of the hollow volumes of another block without the use of a mortar mixture. 
   
   
       16 . A prefabricated fit in block according to  claims 15  wherein the pillars and walls are free-standing. 
   
   
       17 . The prefabricated fit in block according to  claim 15  wherein the pillars and walls comprise a plurality of inner channels for the installation of light fixtures, water fixture, electrical wiring or combination thereof. 
   
   
       18 . The prefabricated fit in block according to  claim 15  wherein the pillars and walls are stable and monolithic. 
   
   
       19 . The prefabricated fit in block according to  claim 15  wherein the pillars have a square section and are obtained by providing alternatively successive layers of the blocks, wherein the blocks are linked to successive superior layers when turning ninety degrees their orientation. 
   
   
       20 . The prefabricated fit in block according to  claim 15  wherein the walls are obtained by providing successive blocks layers. 
   
   
       21 . A system for raising pillars and walls by dry method comprising:
 1) at least two prefabricated fit in block of portland cement mortar reinforced with steel fiber;   wherein each block has a length, a cross section, a longitudinal section, and a volume;   wherein each block has a shape which comprises a rectangular base parallelepiped having a top end, a bottom end, a length, a width, and a height, and interior;   wherein the length is double the width and a height that is a third of the length;   wherein the interior comprises a two hollow volumes symmetrically placed;   a first square base straight prismatic tower and a second square base straight prismatic tower, wherein the first and second towers are identical and are symmetrically placed to overpass the top end of the rectangular base parallelepiped;   wherein each one of both symmetrical hollow volumes includes a first and a second prismatic segment of square base of different dimensions arranged one on top of the other, the first and second segments having a top end and a bottom end, wherein the top and the bottom ends are opened;   2) a lintel beam of portland cement mortar reinforced with steel fiber, the lintel beam having a length, a cross section, a longitudinal section, and a volume;   wherein the lintel beam is of identical cross-sectional section to the cross section of the block, wherein the length of the lintel beam is equivalent to a multiple of the length of the block, wherein the longitudinal section of the lintel beam is equal to the longitudinal section obtained by placing several blocks aligned; wherein the volume of the lintel beam is equivalent to the volume of several blocks united;   3) a prefabricated fit in head-block of portland cement mortar reinforced with steel fiber, the head block having a length, a cross section, a longitudinal section, and a volume;   wherein the head-block has a shape that derives from the shape of the block being eliminated the first and second towers and the rectangular base parallelepiped is provided with a solid superior face;   wherein the solid superior face is obtained by filling the superior prismatic segments of the hollow volumes of the parallelepiped;   4) at least one semi-block, wherein each semi-block has a length, a cross section, a longitudinal section, and a volume;   wherein the semi-block has a shape that derives from the shape of the block when a transversal cross-sectional section is performed; and   wherein the pillars and walls are free-standing since they are raised by connecting successive layers of blocks, semi-block, head block and lintel beams one in the other or one over others.
