Al2O3, and Fe2O3, which confirms that this fly ash is a class C type according to ASTM C 618-05. In addition, calcium-aluminum-silicate-hydrate (C–A–S–H) phases were found in S/S-treated samples but in traces in residues treated with GU only (Table 12.4). These findings coul...
The incorporation of Al and increased curing temperature promotes the crystallization and cross-linking of calcium (alumino)silicate hydrate (C-(A-)S-H), which is the primary binding phase in most contemporary concrete materials. However, the influence of Al-induced structural changes on the ...
4) calcium silicate hydrate 水合硅酸钙 1. According to the molar ratio of n(CaO)/n(SiO_2)=2, using calcium hydroxide and sodium silicate as raw materials,calcium silicate hydratewas synthesized at 100 ℃. 以氢氧化钙和硅酸钠为原料,按照n(CaO)/n(SiO2)=2在100℃合成了水合硅酸钙,并研究了水...
CONSTITUTION:The alumina-calcium silicate hydrate composite has the compsn. CaO-SiO2-Al2O3-Na2O-H2O and has the weight ratios of Ca/Al+Si=0.5 to <0.7, Al/Al+Si=0.1 to 0.15 and NaAl+Si=0.1 to 0.36. This composite is produced by holding, for example, an aq. silica sols-sodium ...

Calcium silicate hydrate (C-S-H) is the main constituent of hydrated cement paste and determines its cohesive properties. Because of the environmental impact of cement industry, it is more and more common to replace a part of the clinker in cement by secondary cementitious materials (SCMs). Th...
Abstract The time-dependent viscoelastic response of cement-based materials to applied deformation is far from fully understood at the atomic level. Calcium silicate hydrate (C-S-H), the main hydration product of Portland cement, is responsible for the viscoelastic mechanism of cement-based materials...
The binding of alkalis and calcium to calcium silicate hydrate (C-S-H) can be measured by cation exchange using cobalt hexamine solution with adapted pH. The effective cation exchange capacity (CEC) decreased at higher Ca/Si in C-S-H. A maximum of chargeexch/Si of 0.08–0.10 was measured...
