ART-S35 is a low-sensitivity, high-slump-retention polycarboxylate superplasticizer independently developed by ARIT with full intellectual-property rights. By virtue of a unique star-shaped polymer topology, precisely controlled slow-release functional groups are embedded along the main chain, enabling an optimal balance between initial dispersion and sustained slump retention. Even under the demanding condition of a low initial slump (80 – 120 mm), the admixture markedly retards early cement hydration and the re-agglomeration of cement particles, keeping fresh concrete flow-stable for more than 4h. This effectively overcomes the sharp slump-loss drawback of conventional superplasticizers in low water-to-binder systems. Optimized ratios of anchoring groups and steric-hindrance side chains greatly reduce sensitivity to fluctuations in cement mineralogy, supplementary cementitious materials (fly ash, slag) or ionic composition of mixing water. Consequently, ART-S35 delivers outstanding performance stability and environmental adaptability despite variations in raw-material source or batch.

Large-scale continuous foundation-slab pour
A Jiangsu commercial-complex raft is 2.5 m thick and was cast in a single, long shift. With ART-S35 the low-slump concrete held its workability for 6 h, practically eliminating slump loss, cold joints and thermal cracking and giving a monolithic, defect-free slab.
Ordinary ready-mixed concrete
A Zhejiang supplier had to haul concrete > 2h to an infrastructure site where aggregate quality varied from load to load. ART-S35 kept the mix stable for 4 h without segregation or bleeding; its low-sensitivity chemistry cancelled the effect of raw-material fluctuations and guaranteed successful long-distance pumping even in midsummer heat.
High-rise construction in hot weather
A Fujian super-tower was cast when ambient temperature exceeded 35 °C and pumping heights were large. ART-S35 gave a controllable initial slump and retained good workability after 2h of transport and pumping, enabling continuous lifts and meeting all strength requirements.
Underwater pile for a nuclear power plant, South China
Large-diameter piles were placed underwater at a slow pace, demanding long-lasting fluidity and strong resistance to segregation. At low slump the concrete with ART-S35 stayed flowable for > 5h and proved insensitive to batch-to-batch changes in cement and fly ash, securing continuous, defect-free placement of these safety-critical elements.
The recommended effective solids content is 0.02 % –0. 15% 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.
It is recommended to combine this product with a water reducing polycarboxylate superplasticizer to achieve optimal performance.
