EPS Building System is CHANGING THE CONSTRUCTION METHODS WORLDWIDE

In a world grown accustomed to evolutionary change one remarkable building, system is making a truly revolutionary impact on global construction methods – the EPS panel system.

-The components of the EPS panel system are simple – a more modified expanded polystyrene flanked by wire mesh connected with galvanized truss wires, field–coated with concrete.

-Yet its extraordinary designs, flexibility, ease of installation, veracity of application, and astonishing strength are changing the way construction industry sees the future.

STRONGER THAN BLOCK.MORE VERSATILE THAN STONE WALLING& FASTER THAN EITHER.

Introduction NHC EPS Factory Rising cost of construction , expensive cost of finance - housing unaffordable to the majority of low and middle-income earners.

EPS Factory - established at Mlolongo area - Mavoko of Machakos County in Eastern Province, a short distance from Nairobi, in May 2012 by National Housing Corporation which is wholly owned by the Government of Kenya at a cost of around KES 1 Billion.

The establishment of an EPS production factory is part of NHC vision to ensure that Kenya is a decently housed nation. This factory which is mandated to produce quality and affordable construction materials using new the technology will go a long way in provision of adequate and affordable housing.

The use of EPS panels as a substitute to traditional materials used in erecting walls, stairwells, floors and roofs is expected to reduce construction periods as well as direct and indirect building costs. Besides return on capital invested, building a house using the EPS panels will significantly take less time than when constructing using conventional materials such as stones.

GENERAL DESCRIPTIONSEPS PANELS - Modified expanded polystyrene Core of 80mm - 200mm.

- Two outer layer of 50 mm x 50 mm wire mesh.- Galvanized Truss Wire pierced core and are welded to the outer Mesh Layers

- Field applied Shortcrete EPS Panels are produced to exacting tolerance using potential high speed machinery. The panel’s lightweight yields dramatic advantages in lower transportation costs, easy job–site handling, rapid erection and installation.

- The EPS System allows the architect/engineer to design for various wind loads and seismic conditions. By varying the size of the wire reinforcement, thickness of shotcrete and incorporating formed-in-place beams and columns, most structural requirements can be met.

- The EPS panel system can be used in many buildings applicants; i.e. residential, commercial industrial and institutional; and is designed to meet standards building code requirements.

- The 3D panel system can be used in single story facilities, curtains, and privacy walls, sound barriers, load-bearing, non-load bearing retaining walls and roofs.

THE CONCREWALL SINGLE PANEL USED AS BEARING ELEMENT IS FINISHED ON SITE THOUGHT STRUCTURAL PLASTER APPLICATION ON EACH SIDE. THE STANDARD FINAL THICKNESS OF ABOUT 3 CM. THE PANEL WILL FORM A PLATE OF REINFORCED CONCRETE WITH EXPANDED POLYSTYRENE CORE. THE STRUCTURAL PLASTER WILL HAVE MIXED CHOOSING SAND WITH GRANULOMETRY FROM 0 TO 5MM AND FINAL RESISTANCE OF AT LEAST 200 ÷ 250 DAN/CM2, VARIABLE ACCORDING TO THE STRUCTURAL PANELS AND GEOMETRY BUILDING CONDITIONS. THE PLASTER SHOULD HAVE A PLASTIC CONSISTENCY S2 (MEASURED SETTLEMENT WITH ABRAMS CONE LESS THAN 5CM).FOR STANDARD DOSAGE IN ONE CUBIC METER OF MASS, THE INDICATIVE QUANTITY OF EACH MATERIAL SHOULD BE:

CONCRETE 350 KGSAND WITH MIXED GRANULOMETRY 1600 KGWATER 160 KG (LITERS)

THE QUANTITY OF WATER MAY BE DIFFERENT ACCORDING TO THE NATURAL SAND HUMIDITY.THE FOLLOWING PARAMETER THAT SHOULD BE CONSTANT:

A/C ~ 0,52I/C ~ 4,5

THE SAND QUALITY SHOULD BE WITHOUT CLAY OR ANY ORGANIC SUBSTANCES AND TOTALLY WASHED.ANY PROBLEMS OF WORKABILITY MUST BE SOLVED WITHOUT ADDING WATER, AND USING FLUIDIFYING ADDITIVES DOSED ACCORDING TO THE MANUFACTURER'S SPECIFICATIONS. THE RETRACTION CRACKS FORMATION CAN BE AVOIDED BY ADDING POLYPROPYLENE FIBERS INTO THE MIX (ONE KG PER M3).
