Calcium sulphoaluminate

Tables 6.2 and 6.3 give data for these phases. C4ASH,2 (or C3A CS H12) is variously known as monosulphate, monosulphoaluminate, or, in the early literature, low-sulphate calcium sulphoaluminate. The water contents of the... Tables 6.2 and 6.3 give data for these phases.

In the presence of magnesium hydroxide the pH decreases to 10.5 and C-S-H is not stable. MgSO reacts with calcium sulphoaluminate hydrates they decompose with the formation of gypsum and Al(OH)3. [Pg.445]

There are the three technologies of the K type laments production. Expansive clinker can be produced composed of alite, C4A3S, C AF and CS however, it is not convenient because the calcium sulphoaluminate is decomposed in rotary kiln already at temperature of 1,350 °C. The better solution is to produce expansive... [Pg.635]

Calcium sulphoaluminate cements These are made from clinkers that include ye elimite (Ca4(A102)gS04 or C4A3 in Cement chemist notation) as a primary... [Pg.203]

Naturally occurring alum or rock alum is an important ore of aluminium and is used in numerous manufacturing processes. It is also used as a mordant in the dye industry. Commercial aluminium sulfate is also known as cake alum or patent alum. There is also an aluminium sulfate mineral, alunogen. Ettringite forms primarily as a component of hydrauhc lime plasters. It is also hsted as calcium sulphoaluminate in the Colour Index as Cl 77235/Pigment White 33. [Pg.9]

Hi) Flaw enlargement and notching The bonding and flexural mechanisms to account for reduction in mechanical properties due to microstructural changes have been recently challenged by Purnell and co-workers [52,64,86,87], based on the observation of ageing of GRC with different types of matrices Portland cement with 20% metakaolin and calcium sulphoaluminate cement. [Pg.311]
