文摘The effects of superabsorbent polymers on the shrinkage and mechanical properties of concrete were investigated.Results of shrinkage tests show that SAP addition reduces the shrinkage.Especially,for the concrete with 3.84 kg SAP/m3 concrete,the shrinkage is little.Compressive strength of concrete with SAP is lower than that of concrete without SAP.However,for the concrete with SAP,the ratio of compressive strength at 90 days to one at 3 days is larger than that of concrete without SAP.
