Silikaltsiidi (Silikaltsiit)

Silicalcite, aka silicate concrete, a building-material more commonly known as Laprex, invented and manufactured by Johannes Hint (brother of Aadu Hint, see Vesse), perhaps the only businessman under Soviet occupation to form a joint-venture with the outside world (Austria). Hint was arrested under trumped-up charges in 1981 and sentenced to 15 years. He died of heart attack in Patarei prison (see Suur-Patarei) in 1985. Street home to Silikaat AS, Estonia’s oldest(?) sand and silicate product producers. Part of a sand and concrete materials group, see Kukermiidi.
