Chloride Resistance Mechanism of Steam-cured Concrete Incorporating a High-resistance Admixture for Chloride Attack

Chloride Resistance of Concrete

Influence of Silica Fume on Chloride Resistance of Concrete

A series of concrete slabs were cast with 0, 7, and 12% by mass silica fume replacement of cement at W/CM = 0.35, 0.40, and 0.45. After either moist or steam curing, a variety of chloride resistance tests were performed. These included AASHTO T259, modified T259, T277, as well as several bulk diffusion tests and sorptivity tests. Results indicate that the use of properly dispersed silica fume r...

Research on Chloride Penetration Resistance of Phosphoaluminate Cement Concrete

The chloride penetration resistance of phosphoaluminate cement (PAC) concrete was investigated in this study. The effects of mixture proportioning parameters, including cement content, water–cement ratio (w/c), and superplasticizer content on chloride ion penetration resistance of PAC concrete were investigated by the rapid chloride migration test (RCM). The result shows that the increase of ce...

Concrete Carbonation and Chloride Resistance Under Initial Hot Water Curing

Three concrete mix proportions were designed and prepared, respectively, such as fly ash concrete (abbreviated as “FAC”) with 30% fly ash replacement ratio of cement, fly ash, and slag concrete (abbreviated as “FSC”) with each of 20% fly ash and slag replacement ratio and ordinary Portland cement concrete (abbreviated as “OPC”) for the research of carbonation and chloride resistance of concrete...
