Spritz Beton Emc Tunnel Concrete

Engineering classification of rock masses for the design of

An analysis of some 200 tunnel case records has revealed a useful correlation between the amount and type of permanent support and the rock mass qualityQ, with respect to tunnel stability. The numerical value ofQ ranges from 0.001 (for exceptionally poor quality squeezing-ground) up to 1000 (for exceptionally good quality rock which is practically unjointed). The rock mass qualityQ is a

Energetically modified cement - Wikipedia

An EMC is a fine powder (typical of all cements) whose colour depends on the material processed. The purpose of an EMC is to replace the Portland cement requirement in the mortar or concrete being used. EMC Activation is a dry process. EMCs are produced using only a fraction of the energy used in Portland cement production.
