THE USE OF RHEOPLASTIC MORTARS IN THE STATIC STRENGTHENING OF ROAD TUNNELS

L'USO DELLE MALTE REOPLASTICHE NEL CONSOLIDAMENTO STATICO DELL GALLERIE STRADALI

Rheoplastic mortar is a concrete mixture obtained by adding to the correct dosage of accurately selected aggregate, a special high strength cement containing accelerating and highly fluidifying additives. The result is a mortar of high workability and very low water cement ratio, free from segregation and bleeding. During setting and hardening this mortar is slightly expansive, thus eliminating the microcracking due to shrinkage. This article describes and illustrates the use of a rheoplastic mortar (EMACO) in the strengthening and retaining of the LEMMEN tunnel on state road SS 370. (TRRL)
