24、TE: Select one of the following two paragraphs depending on the type of grout required. Last paragraph is applicable to either selection. Types are described as follows:Type A grout derives its expansive properties from oxidation of metallic aggregate. Oxidation and consequent expansion may be expec
25、ted to continue until either the aggregate has been completely oxidized or until the grout, in plane, has been sealed off from further contact with oxygen.Type B grout derives its expansive properties from the liberation of gas into the mixture during and after mixing. Chemical reaction causes evolu
26、tion of hydrogen gas. Expansion may be expected to continue until either the gas-liberating mechanism has been exhausted or until the mixture has solidified to such an extent that the tendency for evolving gas to expand is effectively resisted by the stiffness of SECTION 03 62 16 Page 5Provided by I
