Various tests and researches show that increased activity of cement in presence of soluble silica is due to formation of initially colloidal lime hydrosilicate; transition period from colloidal to solid stage is marked by temporary drop in strength, as confirmed by numerous tests; this drop, noticeable at 7 days, is entirely obliterated after 28 days water curing, when strength values of cement with admixtures of soluble silica are considerably higher than those of ordinary cement; in accordance with earlier test evidence, temporary drop in strength becomes manifest in cement; water-cured specimens soon show more rapid rise and their values exceed those of cement without admixture at 28 days; at 90 days this advantage becomes considerable; above applies only to water-cured specimens. See brief translated abstract in Rock Products, vol. 30, no. 7, Apr. 2, 1927, p. 80. (See also - n 15 Feb. 19 1927, pp. 223-225)
