GRC inorganic non-combustible composite material lightweight box

Abstract

The invention discloses the technical field of building materials, particularly relates to a GRC inorganic non-combustible composite material lightweight box, and more particularly provides an inorganic non-combustible composite material lightweight box that is light in weight, high in strength, not liable to damage, high in fireproof degree, molded in one body with a cast-in-place concrete structure, free of construction joints, beautiful and good in sound-insulation, anti-drop and anti-seepage effects. The box comprises a main box body. The main box body is formed by mold internal casting and molding with glass fibre reinforced concrete or formed by casting plates and joining. The glass fibre reinforced concrete comprises 20-30% by mass of cement, 20-25% by mass of sand, 25-30% by mass of ground perlite, 15-20% by mass of water, and 1-2% by mass of glass fiber, with the balance being polymers, additives or a pozzolanic active material.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a lightweight box made of GRC inorganic non-combustible composite material. Background technique [0002] Thin-walled box, also known as floor filling form, is a special formwork used for the construction of cast-in-place two-way densely ribbed slabs, and is widely used in the field of building materials; The material is usually a cement mortar layer box, a foam-filled mortar box or an assembled laminated box, and the main body of a honeycomb core box. However, the main body of the cement mortar box has the problems of large weight, low strength and easy damage. The fire protection level is low, the strength is poor and easy to break, the installation of the main body of the laminated box and the honeycomb core box is cumbersome, it is not integrally formed with the cast-in-place concrete, there are construction joints, and the sound insulation and anti-drip effect is ...
