GRC lightweight porous partition wall slab full name glass fiber reinforced cement lightweight porous partition wall slab, also known as "GRC hollow slat" is based on alkali-resistant glass fiber and low alkalinity cement as the main raw material for non-loading lightweight and porous Inner partition wall slats.
GRC lightweight perforated strips can be used as non-load-bearing inner partitions and as peripheral retaining walls for public, residential and industrial buildings.
The cement used for the production of GRC hollow slats requires low alkalinity (cement filtrate pH ≤ 11) cement. The varieties are: fast hard sulphoaluminate cement, type I low alkali sulphoaluminate cement and low alkali sulphoaluminate. Three kinds of cement. Alkali-resistant glass fiber reinforced materials mainly include: alkali-resistant glass fiber roving, alkali-resistant glass fiber mesh, and alkali-resistant chopped yarn. The auxiliary cementing materials and light aggregates are fly ash, expanded perlite, slag, slag, ceramsite, pottery sand, and the like.
The technical specifications of GRC lightweight porous partition wall slabs implement the national building materials industry standard (JC 666-1997). This standard is applicable to prefabricated non-load-bearing lightweight porous partition wall and GRC curtain wall with alkali-resistant glass fiber and low alkalinity cement as main raw materials.
The model of GRC lightweight porous partition wall slab is divided into 60 type, 90 type and 120 type according to the thickness of the board. It is divided into ordinary version (code PB), door frame board (code MB) and sash board (code CB) according to the plate type. ), and the beam plate (code LB) and so on. According to its physical and mechanical properties, dimensional deviation and appearance quality, it is divided into first-class products (B) and qualified products (C).
The product marking method of GRC lightweight porous partition wall slab is GRC plate type code plate length * plate width * plate thickness grade standard number. The product code is composed of the abbreviation GRC of the main raw material of the product and the type code of the plate type. For example, the first door frame version with a plate length of 2650M and a width of 60mm is marked as GRC MB2650*600*60 BJC 666.
There are currently three industry standards related to GRC hollow slats:
1 Construction industry industry standard "Residential partitions and lightweight slabs" (JG/T 3029-1995), which is common to GRC perforated plates, gypsum hollow slats, aerated concrete slabs and ceramsite concrete slats standard;
2 Building materials industry standard "glass fiber reinforced cement lightweight porous partition wall strip" (JC 3063-1997), is a special standard for GRC multi-well plate;
3 The construction industry industry standard "Industrial ash slag hollow partition wall slab" (JG 3063-1999) is a suitable standard for making slats by mechanical extrusion using industrial waste such as fly ash and slag as raw materials.
