Description

technical field

[0001] The invention relates to a lightweight porous strip, in particular to a fly ash concrete lightweight porous strip and a manufacturing method thereof, belonging to the field of new building panels. Background technique

[0002] Existing industrial ash slag concrete and other lightweight hollow partition wall slats all use cement as the cementitious material, fly ash as the admixture, and mix it into a concrete mixture, which is formed into a slab by screw extrusion or group forming. The strength of the product is formed under natural curing at room temperature or ordinary steam curing at 90°C to 100°C. The material mix ratio is based on the traditional experience, according to the strength theory, the ingredients are designed, and the mix ratio is adjusted according to the requirements of the surface density; the hydration products formed in the product are mainly CSH gel and Ca(OH) with poor crystallinity. ) 2 Crystals constitute the structural stren...
