摘要:
The adsorption of calcium lignosulfonate and salicylic acid was studied on the hydration products of the four principal components of portland cement. To investigate the adsorption as a function of development of hydration product, the determinations were made after varying hydration times. The times allowed were from 5 min to 24 hr for tricalcium aluminate (C3A) and tetracalcium aluminoferrite (C4AF) and from 1 hr to 28 days for β‐dicalcium silicate (β‐C2S) and tricalcium silicate (C3S). Samples were characterized with respect to surface area and poresize distribution. The effect of gypsum on the adsorption was also investigated. The results indicate that the amounts of salicylic acid and calcium lignosulfonate adsorbed on the hydration products of C3A, and of c

摘要:
Equilibrium diagrams for the joins CaAl4O7‐MgAl2O4, CaAl4O4‐Ca2Al2SiO7‐MgAl2O4, and Ca2Al2O4–Ca2Al2SiO7‐MgAl2O4were determined by the classical quenching method and hot stage microscopy. Liquidus relations in the quaternary subsystem are discussed. Two univariant curves are located within the composition tetrahedron. The quaternary invariant point is a peri‐tectic. Technological application of results i
