Introduction to the technology of polymer gravel concrete.

Polymer gravel concrete is mixed in the mixing tank with concrete by adding polymer WDO synergist, colorant, dispersant, fiber and other additives into the paving site to optimize the concrete mix ratio.

The polymer concrete is paved on the working face, and the coarse leveling concrete is scraped with special tools to lift the slurry. The concrete surface is sprinkled with aggregates of different colors of design effect. The aggregates are embedded in the concrete with professional tools. In order to ensure the stability of large-scale construction, the strength time of the slurry on the aggregate surface and the foundation concrete is controlled by chemical retarder and passivator, and the slurry on the aggregate surface is washed off with water, So as to achieve more or less or deep or shallow uniform exposure effect of aggregate.

This construction method utilizes the quality standards of commercial concrete itself, which not only realizes the feasibility of large-scale and standardized construction, guarantees the design quality and application quality of the construction ground, but also achieves the effect of surface decoration and beautification. Polymer gravel art stone washing surface - stone washing surface gravel concrete

Polymer gravel concrete presents a type pattern.

Beautiful Earth. Start from scratch

1. Polymer Gravel Concrete Spreading Aggregate Finish (Style 1)

Exposed auxiliary material finish formed by coating decorative aggregate on plastic concrete. Aggregate particles shall be uniform in size and shall be washed before sowing. Distribute the aggregate evenly on the surface, and press the aggregate into the concrete with a hand trowel or a scraper. Expose aggregate by water washing or retarder treatment

2. Polymer gravel concrete acid washed sand surface finish (style 2)

Clean the mortar layer on the surface by applying an approved surface retarder or acid diluent to the hardened concrete surface. The Contractor shall take necessary precautions to protect surrounding materials and finishes from acid solutions, including the control and proper cleaning of acid and cement cleaning water on concrete.

3. Polymer gravel concrete surface brooming finishing process (style 3)

Drag a clean bristle brush over the plastic surface to obtain uniform stripes and form a brushed finish. Stripe directions on adjacent panels shall be staggered.

1) Light surface sweeping: It is made by pushing and sweeping with a medium to high hardness synthetic brush.

2) Medium face brush: push and sweep with medium to high hardness palm brush.

3) Heavy surface sweeping: the price of polymer gravel floor made by sweeping with a high hardness palm brush or steel wire brush. Gravel floor manufacturers focus on quality, polymer gravel art stone washing surface, stone washing surface gravel concrete, polymer gravel concrete technology, polymer gravel concrete construction

4. Polymer gravel concrete salt finishing process (style 4)

Scatter rock salt crystals of certain specifications on the surface of plastic concrete at the rate of 450 grams per square meter of surface area and press the crystals into the surface with a wooden scraper. After the concrete has passed sufficient curing time and will not be damaged by cleaning treatment, the rock salt crystals shall be dissolved and washed with water.

5. Gravel concrete exposed aggregate finishing process (style 5)

a. Water washing: use slightly controlled water spray and scrub with a stiff brush to clean the mortar surface layer until the fine aggregate particles in the concrete emerge.

b. Retarder: by coating the surface retarder solution on the concrete surface, affect the shaping of the surface mortar, clean the mortar surface, and then wash the retarder solution with water washing and/or wiping to expose the aggregate and obtain the expected surface texture.

6. Art Imprint and Pattern Texture Finishing Process (Style 6)

a. In order to obtain customized patterns and textures as shown on the drawings and consistent with the confirmed samples, preformed pads, dies and other required tools of consistent design shall be provided.

b. Release agent for texture pattern: two-color mixed with watercolor powder.

c. Pouring:

1) According to the relevant technical specifications in this article, the concrete mixture is prepared and poured.

2) After finishing troweling, color release agent shall be applied, about 1.6kg per 10 square meters of surface area. The amount of release agent can be increased if necessary according to the concrete condition and the depth of the impression texture.

3) The embossed pattern or texture on the surface shall be attached to the pattern.

4) The pattern impression or finish appearance shall be free from "irregular wear" and shall fully reflect the required texture.

Main materials of polymer gravel concrete additives.

Polymer gravel concrete consists of four main additive materials, forming the high-tech paving system in the industry polymer modified decorative concrete. It integrates multiple functions and effects such as "color, texture, anti-skid, exquisite and high bearing", and is crack resistant, natural and beautiful, and durable.

Additive A Ruilong HECO synergist

Additive B Ruilong HECO passivator

Additive C Ruilong HECO sealant

Auxiliary D Ruilong HECO light collector

name :　 Ruilong HECO synergist

Application location: Concrete mixing adding

consumption :　 8-10kg per cubic meter

Efficiency of HECO synergist:
● Iron oxide/metal series/dispersant/fiber/● fine particles 400 mesh, high dispersibility ● UV resistant, can be used for a long time under outdoor conditions. ● Does not affect the appearance of the finish and can be dyed ● UF500 tensile strength 90-130KSI ● Absorbs moisture and slowly releases it, contributing to the concrete curing strength. 　

Application method: The synergist shall be removed from the outer package and directly put into the commercial mixing tank for mixing and decomposition. The dosage * high dosage is 5% lower than the cement content in commercial concrete.

name: Ruilong HECO passivator

Application location: Gravel ground surface

consumption: 0.3kg per square meter

HECO passivator efficiency:

● Choose the passivation depth according to the design requirements, which can expose the aggregate to 1-10mm

● Delay the strength of cement for 8-20 hours, and the strength of cement will not be affected after the retarding period

Application:
● Surface passivator can delay the strength time on cement. 　

● Cast, compact and polish the patching aggregate. After the moisture volatilizes, mix and shake the passivator evenly. Spray it evenly on the surface of the concrete gravel ground with a large spray can. Pay attention to the corners. 　

name: Ruilong HECO sealant

Application location: Gravel ground surface

consumption: 0.3kg per square meter

HECO sealant efficiency:
● Polyester resin type
● It can prevent water and pollutants from penetrating.
● The water-based sealant can be opened after the water evaporates/the oily sealant can be painted for 30-40 minutes for surface curing. It can be opened to pedestrians after 2 hours, and meet the design effect after 24 hours.

Application: After curing and cleaning, after drying the ground and volatilizing the moisture, use roller brush/brush/spray bucket and other tools to evenly brush the sealant on the concrete surface, and brush it twice. Be careful not to brush at high temperature or high moisture content to avoid blistering and peeling. 　

Sealants are divided into water-based and oil-based, which can prevent water infiltration and simulate pollution infiltration. The difference is that the water-based penetration into the concrete does not change the color effect of the concrete surface. The surface of the oily sealant is slightly permeated to form a film, which will have the effect of color enhancement and color saturation. At the initial stage, the ground will shine and reflect light, and after 1-2 months, the brightness will weaken with wear.

name: Ruilong HECO light collector

Application location: Gravel concrete surface

consumption: 0.2kg per square meter

HECO light collector efficiency:

● Colloidal silica light collector

● Replace water lubrication without changing the water cement ratio and color of concrete

Application:

● When the concrete is leveled and polished, the aggregate is compacted and polished, or the water loss is too fast, the synergist is sprayed on the concrete with a spray pot to reduce water evaporation and extend the concrete polishing time,

● The polishing agent will reduce the difficulty of polishing, the surface slurry will increase significantly, and the spatula will slide smoothly. 　

● Solved the problem of water cement ratio imbalance caused by water spraying, reducing concrete strength and changing color. 　

● Reduce alkali return of concrete
