WHAT IS RAPID WALL? These are wall panels of 12 m x 3 m made from gypsum, glass rowings and special chemicals. Australian Technology (RBS). As compared to conventional building material, these are More Carpet Area stronger Fast construction light-weight, (just 12% of conventional) Earthquake / Corrosion / fire / termite proof Cheaper++ 91 76667176963

Rapidwall A Revolutionary Building Material RCF produces Phosphoric Acid as an intermediate for Complex Fertilizers Phospho-gypsum is a by product of Phosphoric Acid Plant. Disposal of phospho-gypsum only to a limited extent. Rest is accumulated over years. Value addition to this by-product by making useful building material - Rapidwall++ 91 7666717696

Structure of Rapidwall Panelsreinforced by glass rovings

Panel is reinforced by micro-strand glass rovings (13 microns) by both ways on all four sides - both flanges and webs. This reinforcement provide load bearing capability & confinement property when cavities filled up with concrete.Tensile strength of glass roving (single filament) is 3100-3800 Mpa (tensile strength ofglass roving is much higher than even that of steel used for concrete reinforcement which is maximum @ 500 Mpa)

Elastic Modulus of glass roving is 76-78 Gpa This provide very high load bearing capability to the panel making into a composite material.

STANDARD WALL PANEL SPECIFICATION WATER RESISTANT RAPIDWALL PANELWater resistant Rapidwall panels are the same as ordinary Rapidwall panels in appearance. However the ingredients of the water resistant Rapidwall are modified specifically to provide water resistance when used externally or in wet areas such as bathrooms or laundries, etc.

EXTERNAL SKINThe two 13mm thick faces making up the panel are collectively defined as external skins as shown in Fig.1

INTERNAL RIBThe 20mm thick ribs inside the panel connecting the two external skins are called internal ribs as shown in Fig.1

CAVITYThe internal hollow cores++ 91 7666717696 panel are called the cavity inside the as shown in Fig.1

STANDARD WALL PANEL SPECIFICATION PANEL LENGTHThe panel length is the maximum horizontal dimension of a single wall without vertical joint as indicated in Fig.1

PANEL THICKNESSThe panel thickness is the distance between the external faces of the two external skins, as shown in Fig.1.

PANEL HEIGHTThe panel height is the maximum vertical dimension of a single wall without a horizontal joint

A AND B SIDEThe smoother side of the Rapidwall panel cast against the machine bed in the manufacturing process is called the A side. The B side is screeded and is relatively rougher than A side ++ 91 7666717696

STANDARD WALL PANEL SPECIFICATION GRADE CLASSIFICATIONRapidwall panel is supplied in three grade classifications:1). Class 1 - Water Resistant grade panels that can be used for external walls, in wet areas and/or as floor and wall formwork for concrete filling; 2). Class 2 - General grade Rapidwall panels that can be used structurally or non- structurally in dry areas. These panels are generally unsuitable for use as wall or floor formwork; and 3). Class 3 - Partition grade Rapidwall panels that can only be used as non- structural internal partition walls in dry only areas

++ 91 7666717696

STANDARD WALL PANEL SPECIFICATION PRODUCT CODINGRapidwall panels are coded using the following convention:-

Where panel type is indicated as G for general grade, W for water resistant grade or P for partition grade. For example a Water resistant l grade panel made in RCF, Trombay plant in Chembur , Mumbai 21st Feb 2010 is ++ 91 7666717696 coded as: - RAPIDWALL 124G-12X3-21FEB10/TROMBAY
