Description
Technical field
The present invention relates to building material field, especially a kind of low alkalinity gel material and preparation method thereof.
Background technology
Cement-based gelling material (such as: concrete) is currently used most artificial engineering material, it have pourable,
The good characteristics such as economic, durable, field fabrication.It brings civilization to the mankind, also causes pollution to environment simultaneously.21 century
The developing direction of concrete should be Eco-friendly concrete, and therefore, Binder Materials should break through the model of traditional building material
Enclose, developing ecology environmental friendliness shaped material, walk Sustainable Development Road.
Use eco-concrete can reduce the load to environment, again can be with natural ecosystems coordinated growth, for manpower
Construct comfortable environment.The pH value that low alkalinity gel material requires aquation solidification later continues at the water not affecting plant growing
Flat so that root system of plant can grow in great numbers wherein.Nowadays the method reducing basicity is mainly nature carbonizatin method and envelope alkaline process,
But the former destroys the microstructure within cement, concrete cementing power is caused to be greatly lowered；High score used by the latter
Sub-toxicity of compound is strong, easily decomposes, and construction cost is high, and therefore above method all can not fundamentally overcome inside eco-concrete
The shortcoming that basicity is too high, therefore a kind of low alkalinity gel material and preparation method thereof is proposed.
