ART-M818C
Viscosity Reducing Type Polycarboxylate Superplasticizer Origin Liquor

ART-M818C is a viscosity-reducing polycarboxylate superplasticizer independently developed by ARIT with full intellectual-property rights. Manufactured by an ester-ether co-polymerization process, the polymer chains are highly regular, giving outstanding adsorption and dispersion of cementitious materials. The product markedly lowers mix viscosity and delivers extremely high workability. It is intended for cement-based mortars and concretes that demand viscosity reduction, high fluidity, high workability and high strength.

Features of ART-M818C

Excellent Viscosity Reduction: Significantly lowers paste viscosity, decreases pipe resistance during pumping, and improves flow performance under all job-site conditions.

Low Dosage Sensitivity: Wide effective dosage window with high controllability.

Fast Dispersion: Rapidly adsorbs on cement particles, giving instant wetting and dispersion.

High Water-Reduction & Compactness: Water reduction ≥ 50%; 2h slump practically unchanged; dosage can be tuned to balance water-reduction and retention time.

Optimized Air Management: Fine, uniform and stable air bubbles; guarantees placeability, strength and durability.

Application Case

High-SCM Ready-Mixed Concrete (C30)

A Suzhou ready-mix plant using a high-SCM blend suffered high viscosity. After adding ART-M818C, the mix became soft, low-viscosity, highly pumpable and uniform, greatly improving operability.

Precast Pipe Piles (C105)

A Shanghai pile factory co-blended ART-M818C with a conventional PCE. Viscosity dropped, pumping speed increased, distribution was uniform and air was well controlled. Steam-cured strength reached 90 MPa and pile surfaces were smooth.

UHPC (C150)

In a Shanghai UHPC plant, ART-M818C gave faster dispersion, larger spread and lower viscosity than competing products. 3-day strength was 10% higher with no loss of later-age strength; surfaces were flat and glossy.

Sulpho-Aluminate Cement System

At a Fujian site, ART-M818C provided rapid early dispersion, enhanced system stability, low viscosity and good cohesion. The mix remained uniform throughout placement without mid-stage bleeding, outperforming commercial references and securing continuous casting and final quality.

Usage Instructions

The recommended effective solids content is 0.20 % – 0.50% of the total cementitious materials; the exact dosage must be predetermined through trial tests according to the raw materials, job-site conditions, construction codes, and technical requirements.
Any change in materials or environmental conditions may also cause the dosage to vary within a certain range, so new tests are required to re-establish the optimum dosage.

Complies with the Following Standards

GB/T 8076-2008

T/CECS 10157-2021 ASTM C494 Type S EN 934-2

Packaging

IBC Tank or Flexitank for customer demand

Storage

It should be stored in a cool and dry place, avoiding direct sunlight, and kept in a dedicated warehouse or a fixed location.
The effective storage period is 12 months. It can still be used after being tested and verified to be qualified if it exceeds the time limit.

Precautions

When changing the type of cement or using newly delivered cement, a compatibility test should be conducted.
Do not use in combination with naphthalene-based admixtures. When using in combination with other admixtures, compatibility tests should be performed.
Strictly follow the construction specifications during application.
