Abstract

The invention discloses a high-cohesiveness light-guiding cement-based composite material and a preparation method thereof, and aims to solve the problem that a traditional material optical fiber is low in cohesiveness with a concrete-based material, easy to fall off, easy to crack and low in tensile strength. The high-cohesiveness light-guiding cement-based composite material comprises self-stress sulphate aluminum cement, medium sand, fine stone, water, coal ash, epoxy resin, isocyanate, butylbenzene emulsion, a Sika third-generation polycarboxylate-type super plasticizer, optical fiber and a KH-570 silane coupling agent; the composite material also adopts a material protecting agent; the mass ratio of the self-stress sulphate aluminum cement to medium sand to fine stone to water to coal ash to epoxy resin to isocyanate to butylbenzene emulsion to Sika third-generation polycarboxylate-type super plasticizer is 1: 1.2: 0.8: 0.36: 0.4: 0.3: 0.28: (5.3% to 6.8%): 0.13%; and the concentration of the KH-570 silane coupling agent is 5%. The invention also provides the preparation method of the high-cohesiveness light-guiding cement-based composite material.

Description

technical field [0001] The invention relates to a material belonging to the field of civil engineering materials, more precisely, the invention relates to a high-adhesive light-guiding cement-based composite material and a preparation method thereof. Background technique [0002] Traditional building walls usually use ordinary concrete as a load-bearing structure, but these walls are opaque, thick and dense. However, building energy saving and architectural beauty have always been the pursuit and consensus of the construction industry. The invention of light-guiding concrete makes the building wall not only play the role of building energy saving, but also has a variety of decorative effects. This special effect turns the bulky and dense concrete material into a crystal clear material. However, in the traditional light-guiding cement-based composite materials, there are problems such as poor adhesion, easy to fall off, easy to crack, and low tensile strength between the opti...
