Problems solved by technology

[0003] As a new type of building material with excellent performance, lightweight concrete has been widely used in my country in recent years due to its unique advantages. However, in practical engineering applications, lightweight concrete not only bears the load, but also suffers from Influenced by various environmental factors, such as temperature changes, freeze-thaw damage, and acid-base corrosion, etc., because the material has many pores, low density, and is not dense enough, it may cause structural damage due to poor durability under unfavorable environmental conditions, seriously affecting Normal use of engineering structures
The traditional scheme directly adds proppant materials such as ceramsite due to poor bonding and compactness, resulting in incomplete and effective improvement of the durability of the material, so it is necessary to effectively improve it

Abstract

The invention relates to a lightweight concrete material and a preparation method thereof, and belongs to the technical field of building materials. According to the technical scheme, the surface of ceramsite is coated with a composite elastomer material to form effective elastic load, so that the mechanical strength of the material is effectively improved, meanwhile, the stress of internal pores of the concrete material can be effectively improved through elastic particles, and the mechanical property of the concrete material is improved from another angle; and according to the technical scheme, the coated porous ceramsite material is used as a modified base material, the roundness of the surface of the base material filled in the concrete material is increased along with the effective load of base particles, the angular coating of the surface is gradually reduced, and the nano sol material is substituted into the concrete, so that the compactness of the concrete is increased, and the mechanical strength of the material is further improved.

Description

technical field [0001] The invention relates to a lightweight concrete material and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] Lightweight concrete is made of cement, water and optional component aggregates, infiltration materials and admixtures according to a certain mixing ratio and stirred evenly to make a slurry, and then mixed with a foaming agent aqueous solution through physical foaming. The resulting fine foam is fully mixed evenly, covered and shaped at the construction site or factory, and cured under certain conditions. After hardening, it is a porous concrete material containing a large number of tiny air cells. [0003] As a new type of building material with excellent performance, lightweight concrete has been widely used in my country in recent years due to its unique advantages. However, in practical engineering applications, lightweight concrete not only bears the load, but also suffers...
