Fly ash adhesive is an environmentally friendly adhesive made with fly ash as the main ingredient and adding certain activators, fillers and modifiers. It is widely used in construction, metallurgy, mining, agriculture and other fields for the preparation of various building materials or the remediation of soil. The following is a detailed introduction to the use of fly ash binder:
Composition of fly ash binder: fly ash binder is usually composed of the following parts: fly ash, activator (such as sodium hydroxide, sodium silicate, etc.), filler (such as limestone powder, quartz sand, etc.) and modifier (such as polymer emulsion, cellulose ether, etc.). The proportions of these ingredients are adjusted according to the specific application needs.
Characteristics of fly ash binder: fly ash binder has good bonding properties, compressive strength and durability. It can effectively utilize industrial waste slag fly ash, reduce environmental pollution, and reduce material costs at the same time. In addition, fly ash binders also have good water resistance and corrosion resistance.
Application field of fly ash binder: fly ash binder can be used to prepare various building materials, such as blocks, plates, floor tiles, etc. It can also be used to remediate soils, improve the bearing capacity and stability of soils. In addition, fly ash binders can also be used in mine filling, road foundation reinforcement and other projects.
How to use fly ash binder: When using fly ash binder, first of all, it is necessary to mix the components evenly according to the design ratio. Then, depending on the specific construction requirements, the adhesive can be applied to the corresponding substrate by spraying, smearing, pouring, etc. After the adhesive is applied, certain curing conditions, such as temperature, humidity, etc., need to be maintained to ensure that the performance of the adhesive is fully utilized.
Precautions for the construction of fly ash adhesive: When using fly ash adhesive, the following points need to be noted:
Before construction, it should be ensured that the surface of the substrate is clean, free of oil stains, floating dust, etc., to ensure the good adhesion between the adhesive and the substrate.
Good ventilation should be maintained during the construction process to avoid the harm caused by volatile substances in the adhesive.
After the construction is completed, the maintenance should be carried out in accordance with the maintenance requirements to ensure that the performance of the adhesive is fully utilized.
During use, attention should be paid to safety protection and direct contact between the adhesive and the eyes should be avoided.
Storage and transportation of fly ash binder: Fly ash binder should be stored in a cool, dry and well-ventilated environment, avoiding direct sunlight and rain soaking. During transportation, severe vibrations and bumps should be avoided to avoid package breakage or adhesive leakage.
The environmental significance of fly ash binders: the popularization and application of fly ash binders helps to realize the recycling of resources and reduce environmental pollution. By using industrial waste residues such as fly ash to prepare binders, it is possible to reduce the production cost of building materials while reducing the extraction of natural resources. In addition, the use of fly ash binders can also reduce carbon emissions in the construction industry, which is conducive to green buildings and sustainable development.
In summary, fly ash adhesive is an environmentally friendly material with a wide range of application prospects. Through reasonable use methods and precautions, it can give full play to its bonding performance and environmental protection advantages, and contribute to the construction industry and environmental protection.
