Abstract

The invention discloses an anti-cracking and corrosion-resistant mortar and a preparation method thereof, specifically relates to the technical field of building construction mortar, and comprises: cement, latex powder, basalt fiber, water, quartz sand and a composite reinforcing agent. The invention can effectively improve the wear resistance, corrosion resistance and high cold resistance of the anti-cracking and corrosion-resistant mortar, and can effectively prevent the anti-cracking and anti-corrosion properties of mortar products in the alpine and plateau environment; it can be made into nano-silver particles, graphene Composite materials with graphene oxide; nano-titanium dioxide can be modified, and then the modified nano-titanium dioxide and graphene oxide can be composited; polyimide fiber is the supporting network in the composite reinforcement, and hollow glass microspheres It can be used as a supporting frame, which can effectively strengthen the stability and safety of the composite reinforcing agent, thereby ensuring the wear resistance, corrosion resistance and high cold resistance of the mortar.

Description

technical field [0001] The invention relates to the technical field of building construction mortar, more specifically, the invention relates to an anti-cracking and corrosion-resistant mortar and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricklaying. It is synthesized by adding water to a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.), also called mortar. Commonly used mortars are: cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. The main difference between construction mortar and concrete is that it does not contain coarse aggregate, and construction mortar is prepared from cementitious materials, fine aggregate and water in a certain proportion. Rational use of mortar plays an important role in saving cementitious materials, facilitating construction and improving project quality. According to different purposes, it can be divided into: ...
