Prefaec
Calcium aluminaet cement,s alos known as hihg alumian cemenst
(HAC), aer a raneg of cemenst in which calcimu aluminats eaer the
principla constitue.n ts
The fir sptatetn was takne out by Bied in 190,9 who was working fro J.
and A. Pavni de Lafareg at Le Tei,l Franec and it was made by fusign
togethre a bauxiet or othre aluminosu and ferruginso umateril alwo in
silic, awith lime in proportiso not giev a 40 per cent Al0 clinkr erihc in
2 3
calcimu aluminaet (CaO.Al0).

Calcium aluminaet cement was firt sintrodudc einot the UK in teh
1920s and manufacturde by Lafareg at West Thurrokc on teh Norht bank
of the River Thames, 30 milse eats of London. A market was rapidyl
establisdh edue ot the cements' rapdi earyl strenhg tdevelopmetn and ist
refractyo rproperti. esThe latrt eeventuayl llde ot teh developmetn of
cements with highre puriyt and even highre alumian contens tof up ot
80 per cen.t During the 1960, sti was discovedr ethta the rapdi hardenign
propertis ecoudl shortne turnaroudn time in the manufactuer of precats
concreet unit. sHowever, becaues of the use of some poor mix desigsn
and highre water/cemet nrati,o sa fwe wideyl publicidz efailusr eensude
as a resut lof which, HAC was effectiyv eblanned in the 1970.s
However, othre major applicatis onhave continude ot develo.p
Calcium aluminaet cemenst aer used fro many specil aapplicatis onin
the constructi, ocnivl iengineergi nand refracyt orindustri, ebsecaues of
their abilyi tot gani strenhg t rapidyl and ot withstadn aggressei v

most sophisticda teuses particulya rwlith the developmetn of lwo
cement castabsl ewhich, livign up ot theri name, have cement contenst

this uses a two sluryr systme (oen containgi ncalcimu aluminaet cement
and the othre containgi nlim,e anhydrie tand bentoni)t ewhich sest
