Fire-resistant foam concrete material and preparation method thereof

Abstract

The invention discloses a fire-resistant foam concrete material and a preparation method thereof. The concrete material is prepared from the following raw materials in parts by weight: 240-300 parts of cement, 0.5-1 part of a water reducer, 1-2 parts of a foam stabilizer, 2-8 parts of early strength agent, 1.6-4 parts of a coagulant, 4-9 parts of fibers, 10-18 parts of a foaming agent, 40-60 partsof fly ash microspheres and 100-160 parts of water. The preparation method comprises the following steps that the cement, the fly ash microspheres, the early strength agent, the coagulant and the fibers are uniformly stirred, then the water, the water reducer and the foam stabilizer are added so as to prepare slurry, and finally the foaming agent is added for uniform mixing. The fire-resistant foam concrete material has the advantages of being good in fire resistance, light in weight, high in strength, good in heat preservation effect, low-carbon, energy-saving and environmentally friendly, alarge amount of industrial waste is utilized for preparing the raw materials, and important significance in the development of experiment economy and society is achieved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a fire-resistant foam concrete material and a preparation method thereof. Background technique [0002] At present, energy saving and consumption reduction are necessary requirements for protecting the environment and people's lives, but the thermal insulation performance of buildings is generally poor. Therefore, the requirements for building energy conservation are urgent at this stage. As we all know, the most important measure of building energy saving is the use of thermal insulation materials. The development of thermal insulation materials with excellent performance is not only the requirement of energy saving, environmental protection and sustainable development, but also meets people's growing demand for improving living conditions. With the development of the economy and the improvement of people's living standards, people's requirements for living, worki...

Problems solved by technology

However, these organic foam insulation materials also have many serious disadvantages: the insulation layer is easy to crack, hollow, and fall off; the insulation material is easy to age, and the insulation layer needs to be replaced many times during the service period of the building, wasting a lot of manpower, material resources, and financial resources.

The construction process of organic thermal insulation materials is relatively difficult, the project cost is high, the ecological and environmental protection of raw materials used in the production of organic thermal insulation materials is poor, the resources required for production are limited, and it is difficult to realize recycling

What's more serious is its high temperature resistance and poor fire safety. Major fire accidents caused by its ignition have occurred repeatedly in various places, causing huge economic losses and a large number of casualties.
