Problems solved by technology

The production method is complex and difficult, not only takes a long time but also the rubber particles are not firmly bonded to the cement; when the prior art configures elastic concrete, in order to ensure a better bonding effect, the amount of adhesive poured into the mix is ​​large, resulting in The cost of materials is high; when used, it needs to be adjusted on site, the site operation is cumbersome, and the construction cost is high

Embodiment 1

[0030] like figure 1 , figure 2 As shown, the present invention discloses an elastic sand, which includes a matrix 1 , an adhesive layer 2 covering the exterior of the matrix 1 and a bonding layer 3 covering the exterior of the adhesive layer 2 .

[0031] The base 1 is rubber granules, the bonding layer 2 is an adhesive layer, and the bonding layer 3 is a cement layer. Wherein, the adhesive layer is formed by an epoxy resin-based adhesive.

[0032] The outer dimension of the elastic sand formed by the matrix 1, the adhesive layer 2 and the bonding layer 3 is 1mm.

Embodiment 2

[0034] The invention discloses an elastic sand, which comprises a matrix 1 , an adhesive layer 2 covering the exterior of the matrix 1 and a bonding layer 3 covering the exterior of the adhesive layer 2 .

[0035] The base 1 is rubber granules, the bonding layer 2 is an adhesive layer, and the bonding layer 3 is a cement layer. Wherein, the adhesive layer is formed by emulsified asphalt.

[0036] The outer dimension of the elastic sand formed by the matrix 1, the adhesive layer 2 and the bonding layer 3 is 2mm.

Embodiment 3

[0038] The invention discloses an elastic sand, which comprises a matrix 1 , an adhesive layer 2 covering the exterior of the matrix 1 and a bonding layer 3 covering the exterior of the adhesive layer 2 .

[0039] The base 1 is rubber granules, the bonding layer 2 is an adhesive layer, and the bonding layer 3 is a cement layer. Wherein, the adhesive layer is formed of polyurethane.

[0040] The outer dimensions of the elastic sand formed by the matrix 1, the adhesive layer 2 and the bonding layer 3 are 3mm.

[0041] Instructions:

[0042] According to needs, weigh a certain amount of elastic sand, cement, concrete, coarse aggregate, fine aggregate and water, mix and stir the above materials, and then complete the preparation of elastic concrete.

[0043] The elastic concrete is prepared on site without weighing the adhesive, which reduces the process, saves on-site construction time, saves time and effort, is efficient and convenient, and reduces the construction cost.

Abstract

The invention discloses elastic sand, which relates to the technical field of building materials; it comprises a base body (1), an adhesive layer (2) arranged on the base body (1), and a bonding layer arranged on the adhesive layer (2) layer (3); the elastic sand is formed through the matrix, the adhesive layer and the bonding layer, which realizes the efficient preparation of elastic concrete, reduces the production cost, and reduces the construction cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to elastic sand. Background technique [0002] In Guo Yin's "A Review of Elastic Concrete" paper, elastic concrete (Elastic Concrete) is a new type of concrete that uses rubber particles as a component of cement concrete. This is a new type of building material, a kind of concrete introduced from foreign countries in recent years. In terms of performance, this concrete is between rigid concrete and flexible concrete. Its remarkable performance is that the ductility of this concrete is increased after adding rubber particles. It exhibits a bending state rather than a brittle fracture when subjected to enormous pressure. However, the compressive capacity of concrete mixed with rubber particles is significantly reduced. At present, many researches at home and abroad are devoted to the analysis of the compressive and flexural properties of elastic concrete. Most studies ta...
