Abstract

The invention discloses an ultrahigh-toughness cement-based composite material (UHTCC) which can be used in ejection, and an ejection process thereof. The invention relates to the technical field of ultrahigh-toughness cement-based composite material ejection. The main technical scheme of the invention is that the ultrahigh-toughness cement-based composite material used for ejection is designed based on rheological and micro-mechanical principals; the ejection process of the material is realized through determination and control over key parameters; and quantitative enhancement and crack control of a concrete structure requiring ejection reinforcement are realized. According to the invention, problems of ultrahigh-toughness cement-based composite material ejection, quantitative enhancement and crack control are solved. The technical scheme has the characteristics of simple application, fast and continuous construction, high applicability, realization of material maximal utilization rate, and the like. The material and the process can be widely applied in construction and existing structure reparation and reinforcement in the fields of hydraulic engineering, harbor engineering, traffic engineering, bridge and tunnel engineering, and underground engineering.

Description

technical field

[0001] The patent of the invention belongs to the technical field of ultra-high toughness cement-based composite material spraying. Background technique

[0002] Ultra-high toughness cement-based composite (UHTCC) is a kind of reinforced with short fibers, and the fiber content does not exceed 2.5% of the total volume of the composite. Cracking characteristics, the ultimate tensile strain can reach more than 3% cement-based materials. The strain hardening characteristics and the harmless dispersing ability of cracks possessed by this kind of material fundamentally change the brittle and easy cracking characteristics of ordinary concrete materials, and realize the strain hardening characteristics and ultra-high deformation and crack control ability that ordinary fiber concrete does not have. , can be widely used in water conservancy projects, harbor and sea projects, traffic projects, bridge and tunnel projects, construction of underground projects and repair...
