In this paper, four kinds of agents (2000 polyethylene glycol (pg2000), aminosalicylicacid (ASA), saodium alginate (SA), sodium metasilicate anhydrous (SMA)) were investigated as potential anti-clay agents combined with polycarboxylate water reducer (PCE), and the fluidity, compress strength, and flexural strength of cement paste, mortar, and concrete containing aforementioned anti-clay agents were tested. It found that among the tested potential anti-clay agents, PG2000 have performed well. The fluidity of the concrete with PG2000 increased 16mm compared to the control sample. In order to understand the mechanisms underlying this improvement, X-ray Diffraction(XRD) of cement paste was carried. The results show PG2000 has the highest interlayer spacing(d=2.865142nm) compare with control sample(d=2.828410nm) (not added PG2000), which make it more effective on the fluidity of concrete.
