Concrete is important construction material in civil applications. Portland Cement (PC) is considered the essential component material to produce the concrete, especially in high-strength concrete. Around ranging from 5-7% of CO2 was generated during PC production. Consequently, the concrete and PC production are change in the environment. So; it has become very important for the construction industry to focus on minimizing environmental pollution, energy consumption reduction. Several pozzolanic cementitious materials can be added as a fractional replacement of cement in concrete to reduce PC impact on environmental pollution. Pozzolanic materials include PC as one of its main components as well …

Determination of degrees of hydration/reaction of components of blended cementitious systems (i. e., cement and SCMs: supplementary cementitious materials) is essential to estimate the systems' properties. Although the best methods for determining degrees of reaction of different SCMs have been recommended by RILEM TC238, they rely on either expensive equipment (e.g., nuclear magnetic resonance) or time-consuming sample preparation and data processing (e.g., backscattered electron image analysis). Furthermore, these methods cannot simultaneously characterize degree of hydration of cement and degree of reaction of SCMs. A novel decoupling method, which can simultaneously estimate the degree of hydration of cement and the degree …

Shotcrete for Underground Support XI
The application of blended cements in shotcrete is investigated to reduce the environmental burden. Reduction of the environmental burden and meeting the required properties of quick setting and strength development are achieved using blended cements with blast furnace slag and a powder accelerator with a main component of calcium sulfo-aluminate. The powder accelerator is hydro-reactive and promotes quick setting and strength development in shotcrete. The reduced environmental burden of shotcrete with blended cement and powder accelerator are calculated.
