The stone back bar glue is used for fixing the reinforcing steel bars, and plays a vital role in ensuring the quality of the stone as the glue for reinforcement.
The stone back rib reinforcement at the present stage is mainly made of white cement or marble adhesive, but the white cement or the marble adhesive has some disadvantages. The cement has long curing time, which affects the construction, and at least one week of water adding and curing time is needed, so that the stone is easy to have pathological changes in a humid environment, such as water spots, bloom, wet marks and the like, which affects the appearance; and the cement is prevented from being corroded by acid, acidic substances and calcium hydroxide in the cement can generate neutralization reaction, and the generated objects are loose and expanded and are easy to hydrolyze and pulverize after meeting water, so that the reinforcing steel bars fall off. The marble glue has the problems of large shrinkage rate and brittle performance after curing, and the marble glue is generally viscous paste, is not easy to level in the stone grooving and is not beneficial to construction.

TABLE 1 composition of the Stone Back-rib glue of each example
TABLE 2 composition of various proportions of back-rib glue for stone
TABLE 2 composition of various proportional back bar glue for stone
The flexural modulus, impact toughness and compression shear bonding strength (standard and water immersion) of the cured stone back rib glue in each example and comparative example are tested by referring to a test method of a building material industry standard JC/T989-2016 of the people's republic of China.
