preparation example Construction

[0091] refer to figure 1 Shown, the present invention also proposes a kind of preparation method of modified decorative concrete material, comprises the following steps:

[0092] S1 After weighing the raw materials in parts by weight, mix cement, fly ash, quartz sand, and silica fume evenly to make a premix;

[0093] S2 Add fiber, modified nano-titanium dioxide, modified nano-silver antibacterial agent, admixture and polymer to the premix, stir evenly to obtain slurry;

[0094] S3 placing the slurry in a mold, casting and vibrating, and drying naturally to obtain a decorative concrete material;

[0095] S4 is demolded after high-temperature steam curing at 50-90°C, followed by medium-temperature secondary curing at 35-65°C, and then dried.

[0096] In the above content of the present invention, the raw material includes the following components by weight:

[0097]

[0098] Wherein, the admixture includes at least one of pigments, water reducers, thickeners, retarders, ea...

Abstract

The invention relates to a modified decorative concrete material and a preparation method thereof. The material comprises cement, fiber, polymer, quartz sand, silica fume, fly ash, an additive, modified nano titanium dioxide and a modified nano silver antibacterial agent. The concrete material has the beneficial effects that through the addition and application of the modified nano titanium dioxide, the concrete material is combined with nitric oxide in the sun and converted into harmless nitrate, and nitric oxides in air can be cleaned; through addition and application of the modified nano-silver antibacterial agent, the concrete material has a very good antibacterial property, and mildew spots and pollution resistance on the surface of concrete can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to a modified decorative concrete material and a preparation method thereof. Background technique [0002] As a new type of artificial building material, artificial stone has the advantages of high strength, high hardness, high toughness, anti-corrosion and anti-aging, no radiation, easy processing, and natural texture. It is more and more widely used in the field of construction and decoration. Today, when non-renewable resources such as natural stone are continuously being exploited destructively, it is an inevitable trend in the world's stone decoration market to replace natural stone with artificial stone. [0003] At present, more than 70% of waste rocks are produced by stone mining. To deal with these waste rocks or occupy land for stacking or landfilling, a large amount of valuable land has been destroyed, and stone resources have become a major public hazard that en...
