CMK

HOLLOW CORE SLAB

Hollow core slabs are pre-stressed concrete elements that are generally used for flooring in construction of all building sizes including residential buildings, department stores, warehouses, and industrial plants.

GENERAL SPECS FOR CMK PRESTRESSED CONCRETE SLABS OF SIZE 5 CM TO 25 CM

   Manufactured according to industrial standard (TIS. 828-2546)

   The minimum ultimate compressive strength of a concrete cube after 28 days is 400 ksc. (40 MPa)

   The minimum ultimate compressive strength of a concrete cube while taking pressure is 300 ksc. (30 MPa)

   The minimum ultimate compressive strength of a "concrete cylinder" after 28 days is 210 ksc. (21 MPa)

   Prestressed concrete wires (PC Wire) used in the slabs are under TIS 95 standard

   Prestressed concrete strands (PC Strand) used in the slabs are under TIS 420 standard

   Calculation and design are under ACI 318-83 and PCI-1985 standards

In the process of steel reinforcement of a 5 cm overlay concrete, RB steel grids (Ø6 mm) with a spacing of 20 cm or prefabricated steel mesh (wire mesh) with wire size 4 mm and 20x20 cm spacing are used

Hollow concrete slabs have holes along the length of the slabs. These holes will increase self-strength efficiency. As the result, it can bear more weight than a Prestressed solid slab 


o  Made from dry concrete and modern machinery therefore of good quality and has no deflection problem
o  Convenience and cost savings as it is quick to install so helps reduce human labor.
o  Lightweight compared to other floor structures have strength in itself able to bear heavy weight.
Insulates against noise and temperature due to hollow internal air channels thus reducing the passage of sound and temperature well.
o  The abdominal side has a smooth surface and hollow core. Can be used as a ceiling, insert electrical conduits, water pipes, or can be used as ventilation holes
o  Helps to prevent fire. Able to withstand heat for hours so will contain the damage from adjacent area.

PRESTRESSED SOLID SLAB

Prestressed solid slab are generally used for flooring in construction of small to medium size buildings such as houses and townhouses in which it provides a lower price point than the hollow core slabs.

GENERAL SPECS FOR CMK PRESTRESSED SOLID CONCRETE SLABS OF WIDTH 30 CM AND 35 CM

   Manufactured according to industrial standard (TIS. 828-2546)

   The minimum ultimate compressive strength of a concrete cube after 28 days is 400 ksc. (40 MPa)

   The minimum ultimate compressive strength of a concrete cube before the wires are cut is 300 ksc. (30 MPa)

   The minimum ultimate compressive strength of the overlay concrete is 240 ksc. (24 MPa) for concrete cube

   Prestressed concrete wires (PC Wire) used in the slabs are under TIS 95 standard

   For a 5 cm overlay concrete, RB steel grids (Ø6 mm) with a spacing of 20 cm or prefabricated steel mesh (wire mesh) with wire size 4 mm and 20x20 cm spacing are used

Concrete slabs shaped like a plank. The belly plate is smooth without the need for plastering. But the top is not smooth so it can be easily combined with the poured concrete to form a homogeneous face.


o  It is strong, durable, meets standards, and is cheap compared to hollow slabs.
Lightweight, easy to move and install.
o  Easy to install by manual labor. No need for large machines. This saves time and money.
Smooth surface, close joints, no need to plaster. Resulting in savings on labor and other expenses
