The invention discloses a cement-based adhesive which consists of an inorganic gel, elasticity modulus filler, sand and a dry-mixed mortar additive, wherein the mass percentages of the various components in the adhesive are as follows: 35-45% of inorganic gel, 15-30% of elasticity modulus filler, 17-47% of sand, 3-8% of dry-mixed mortar additive and the balance of water. The cement-based adhesive disclosed by the invention has the following beneficial effects that by adding the low elasticity modulus filler which has the advantages of good elasticity, shock-proofing, sound insulation and the like, the cement-based adhesive has the characteristics of shock absorbing, noise reduction and the like, so that a problem of noise generated from the collision of ceramic tiles in a public place is relieved; in addition, the cement-based adhesive provided by the invention also solves the problems of low compressive strength, low bonding strength and the like of the adhesive after the low-modulus filler is added; shearing strength on the interfaces of the ceramic tiles caused by heat expansion and cold contraction is reduced and the bonding durability of the ceramic tiles on the basis of shock absorbing and noise reduction is improved; therefore, the cement-based adhesive is quite high in promotional value.
