StructureCompositionCrystallinityThe perspective of calcium silicate hydrate (C-S-H) is still confronting various debates due to its intrinsic complicated structure and properties after decades of studies. In this study, hydration at dilute suspension of w/s equaling to 10 was conducted for tricalcium...
Calcium silicate hydrate (C-S-H)Calcium-silicon ratioMicrostructureNanostructureNMRSEMXRDA C–S–H series with calcium–silicon ratio 0.6–3.0 was synthesized by pozzolanic reaction. Phase composition, nanostructural and morphological characteristics were determined using XRD, XRF, SEM and 29 Si NMR. ...
Determining the Influence of Curing Temperature and SCMs on C-A-S-H Composition Using SEM-EDS Hypermaps Calcium-alumina-silicate-hydrate (C-A-S-H) is the main hydration product formed in Portland composite cement pastes. C-A-S-H is a key phase with regard to ... P Hemstad,P Kjellemyr...
Compositional changes in cement-stabilized waste during leach tests--comparison of SEM/EDX data with predictions from geochemical speciation modeling. The geochemical equilibrium model SOLTEQ-B, which accounts for the incongruent solubility behavior of calcium silicate hydrate, was used to simulate the ...
Blast furnace slag (BFS), a high volume byproduct resulting from the iron manufacturing industry, was used as a low-cost and abundant precursor for preparing a high-surface-area calcium silicate hydrate. The synthesis of slag-made calcium silicate hydrate (slagCS) was achievedviaa facile two-...
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...

4) calcium magnesium silicate hydrate 含水硅酸钙镁5) calcium phosphate with silicon component 含硅钙磷酸盐 1. Using this method of preparation of calcium phosphate with silicon component has a good protective effect against decency, suitable for large-scale operation. 在汉白玉石材表面使用后,场...
Incorporation of silica nanoparticles into cement paste improved the microstructure of the paste, and calcium leaching is significantly reduced as silica nanoparticles react with calcium hydroxide (CH) and probably form an additional calciumsilicatehydrate (CSH) gel. It was found that the CH content ...
