Problems solved by technology

When the ALC board is in use, it is inevitable that the weather, humidity, and wall vibration will cause cracks in the ALC board. The existing ALC board repair mortar is more complicated to make when repairing the ALC board, and the adhesion is poor, and the hardening time is longer. , the construction and repair time is longer, which affects the use of ALC boards

Embodiment Construction

[0015] The present invention provides a technical solution: ALC board repair special mortar, each component is: cement 35% -45%, sand 45% -55%, fly ash 8% -10%, can be dispersed Polymer latex powder 2% -5%, plant fibers 0.3% -0.9%, hydroxypropylmethylcellulose 0.4% -0.8%, 2% - 5% of the ventilator.

[0016] Among them, each component is based on its mass percentage: cement 25% -35%, sand 55% -65%, fly ash 4% -8%, re-dispersible polymer latex powder 1% -4%, plant fiber 0.2% -0.6%, hydroxypropylmethylcellulose 0.8% -1.6%, 1% -3% of the ventilator.

[0017] Among them, each component is based on its mass percentage: cement 40% -50%, sand 30% -40%, fly ash 2% -6%, re-dispersible polymer latex powder 5% -10%, plant fiber 2% -4%, hydroxypropylmethylcellulose 2% -4%, 3% -9% of the ventilator.

[0018] Among them, each component is based on its mass percentage: cement 60% -70%, sand 15% -25%, fly ash 0.5% -0.8%, re-dispersible polymer latex powder 3.5% -7.5%, plant fiber 4.6% - 5.2%, hydr...

Abstract

The invention discloses special mortar for repairing an ALC plate, wherein the mortar comprises the components in percentage by mass: 35 to 45 percent of cement, 45 to 55 percent of sand, 8 to 10 percent of fly ash, 2 to 5 percent of redispersible polymer latex powder, 0.3 to 0.9 percent of plant fibers, 0.4 to 0.8 percent of hydroxypropyl methyl cellulose and 2 to 5 percent of an air entraining agent. The special mortar for repairing the ALC plate has the beneficial effects that the special mortar for repairing the ALC plate has the effects of fast setting and hardening, good freezing resistance, large hydration heat and good wear resistance, has relatively high bonding force with a wall body material or other base materials after being hardened, is high in bonding speed, has a relatively good protection effect on the ALC plate, and provides a powerful guarantee for repairing of the ALC plate; moreover, the adhesive mortar is simple to manufacture, the repair construction speed can be greatly increased, and the safety performance of the building is improved.

Description

Technical field [0001] The present invention relates to the field of mortar technology, in particular ALC plate repair special mortar. Background technique [0002] ALC is a referred to as a fluorescent concrete that is a kind of high-performance steaming aerated concrete (ALC). The Alc board is a multi-gas condensate molded sheet (including treated steel reinforced steel) with fly ash (or silica sand), cement, lime, etc., and has been treated with high pressure steam. The ALC board can be made of a wall material, but also a roof panel, a new building materials with superior performance. When the ALC board is used, it is difficult to generate cracks due to weather, humidity, and wall vibration. The existing ALC board repair mortar is more complex when repairing the ALC board, poor adhesion, and has a long hard temperature. The construction repair time is longer and affects the use of the ALC board. Inventive content [0003] It is an object of the present invention to provide an...
