Problems solved by technology

[0003] The preparation of concrete is different according to its different use occasions. For example, the concrete used for bridge pavement construction requires better anti-slip and vibration-reducing properties, the concrete used for building construction requires better strength, and the concrete used for temporary construction sheds requires However, the concrete used for different occasions will inevitably lead to the weakening of another performance when it meets one of the properties. For example, for the concrete used in building construction, the side in production The focus is often on its mechanical strength, with little research on its density, shock resistance, and thermal insulation

[0036] In the present invention, airgel, composite fiber, lightweight filler and foaming agent are the core components of the present invention, which are essential components to make it optimally applicable to building walls: airgel has thermal insulation properties and can Eliminate heat exchange between indoor and outdoor environments, and achieve the effect of warming in winter and cooling in summer; the composite fiber is preferably selected from one or more of stainless steel fiber, polypropylene resin fiber and hydroxyethyl fiber, and the composite fiber can be combined with concrete Form an interwoven network structure between them to improve the structural strength of concrete; lightweight fillers and foaming agents are used to reduce the density of concrete, increase the seismic performance of concrete walls, and reduce transportation costs. The foaming agent can be selected from any existing The foaming agent and the light filler include the following ingredients in ...

Abstract

The invention relates to concrete for building wall construction and a preparation method of the concrete. The concrete comprises the following components, in parts by weight: 30-45 parts of cement, 1-2 parts of ethylene glycol monobutyl ether, 1-2 parts of silicone oil, 40-45 parts of mixed gravel, 10-20 parts of coarse sand, 30-45 parts of fine sand, 10-20 parts of ceramic waste, 10-20 parts of waste concrete, 10-20 parts of fine aggregate, 10-20 parts of aerogel, 15-25 parts of composite fibers, 10-15 parts of a lightweight filler, 10-15 parts of a foaming agent, and 15-25 parts of an admixture. The concrete for the building wall construction provided by the invention has better mechanical impact resistance, compressive strength, anti-permeability strength, bending strength and product compactness, a small thermal conductivity coefficient, low production costs and a light mass.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a concrete for building wall construction and a preparation method thereof. Background technique [0002] Concrete is one of the most important civil engineering materials today. It is a kind of artificial stone made of cementitious materials, granular aggregates, water, and admixtures and admixtures added when necessary, prepared in a certain proportion, uniformly stirred, densely formed, cured and hardened. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. At the same time, concrete also has the characteristics of high compressive strength, good durability, and a wide range of strength grades. These characteristics make it widely used, not only in various civil engineering, but also in shipbuilding, machinery industry, marine development and geothermal. Concrete is also an important m...
