- W4362659730 abstract "Abstract Evaluation and research on the aggressive degree to concrete were done in the previous research. However, the evaluation of aggressive certain degree in water to the concrete was evaluated comprehensively by the Viet Nam Standard “TCVN 3994:1985” and ISO 14911:1998. The results presented “water with chemical characteristics can’t create the aggression in concrete”, which shows pH concentration is 5 and CO 2 corrosion is 20 mg/l; whereas ion Mg 2+ is 1.5 g/l and SO 4 2− is 0,25 g/l. The total salt content in the presence of evaporating surface obtains 12,5g/l. On the other hand, this paper considers water with the chemical name “Chlorite-Bicarbonate-Sodium-Magnesium” by the Kurlov formula and “TCVN 81:1981”. Especially, comprehensive consideration of chemical analysis that includes Cation (C a 2+ ; Mg 2+ ; ∑(Fe 2+ ; Fe 3+ ; Na + ; K + ; and NH 4 + ); Anion (Cl − ; SO 4 2− ; HCO 3 − ; CO 3 2− and OH − ); and the other special items analysis which includes Permanent and Temporary hardness; Alkalinity; CO 2 free; CO 2 corrosive; Total mineralization; pH value; Nitrite (NO 2 −) ; and Nitrate (NO 3 − ). So research results can be used safely for the design or construction of the reinforcement concrete structures in My Thai Canal Bridge, Rach Gia town, Kien Giang province, Viet Nam, and Construction or Geotechnical as good reference documents in the future." @default.
