Quality of Water for Making Concrete: A Review of Literature

Zinc oxide 0.01% weight of cement No significant effect but 0.1% strongly retarded setting time and lowered strength. Ammonium ion No limit available Ammonium chloride increased strength. 0.4, 0.8 and higher percentage by weight of water of ammonium nitrate give same strength as with similar percentage of NaCl in water for making concrete.

TERM-1 SAMPLE PAPER

zinc. Reason (R): Because zinc is less reactive than tin. 33. Assertion (A): Diffusion process does not meet high energy requirement of multicellular organism. Reason (R): Diffusion is a fast process but only occurs at the surface of the body. 34. Assertion (A): In prism, higher the refractive index, lower will be the angle of deviation.

Ferric oxide Heat 42 32 + +SO 3()g 2.3.3 Displacement Reaction The reaction in which one atom or a group of atoms of a compound is replaced by another atom, is called a displacement reaction. Generally, a more reactive metal displaces a less reactive metal from its salt solution in displacement reaction. The series in which metals are arranged in
