Embodiment 1

[0025] The distribution ratio of each component of high-performance structural reinforcement mortar is as follows (winter construction):

[0026]

[0027] Performance indicators of polymer mortar for concrete structure reinforcement:

[0028]

[0029]

[0030] The preparation process of the high-performance structural reinforcement mortar composition of the above ratio, its specific steps are as follows:

[0031] (1) First, the active pozzolan component and each mortar-specific admixture are pre-mixed in proportion;

[0032] (2) Then, the uniformly stirred mixture, 42.5-grade ordinary Portland cement and quartz sand are weighed in proportion, mixed, stirred evenly, and packaged to obtain the high-performance structural reinforcement mortar composition referred to in the present invention.

Embodiment 2

Abstract

The invention discloses a high-performance structural reinforcement mortar composition, which uses 42.5-grade ordinary Portland cement and active pozzolan components as the main ingredients of the gelling material, and uses thickening and water-retaining components, polycarboxylic acid superplasticizers, It is modified by the coagulation-accelerating component, and special anti-crack fiber for mortar, quartz sand, and redispersible rubber powder are also added. The invention adopts redispersible polymer rubber powder and several kinds of active additives, which can effectively improve the durability of the mortar and the durability of the whole formed with the reinforced concrete matrix when added to the basic compound of ordinary mortar, and at the same time, it is harmful to the human body. It is not harmful to the environment and is a new type of energy-saving green building material.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a structure-reinforcing mortar composition with excellent thixotropic performance and durability and whose formula can be adjusted according to different construction environments, and a preparation process thereof. Background technique [0002] A large number of civil and industrial facilities with concrete and masonry structures built during the first construction climax since the founding of our country have not yet reached their design service life, but a considerable proportion of this type of buildings are due to improper use and maintenance or construction quality reasons , there are different degrees of security risks. Therefore, in order to ensure that the building can perform its functions normally within the design service life, it is very important to regularly check the use status of the building and timely repair and reinforce the damage that occurs.
