Rapid screening tests for supplementary cementitious materials (SCMs) have been in use for over 150 years. Over the years a multitude of methods have been put forward to predict the strength development of SCMblended mortars and concrete. This paper summar ...
Calcareous fly ashes are high-potential reactive supplementary cementitious materials, which present an interesting alternative to slowly reacting siliceous fly ashes and to slags, which availability is more and more limited. Themain factor against an accu ...
This dissertation originates from an investigation about the arising of the modern, German building expertise involving the use of concrete, which develops during the first three quarter of the 19th century against the backdrop of a general modernisation p ...
Supplementary cementitious materials (SCMs) are currently used to replace part of the clinker to reduce the environmental impact of cement and to favor the use of local materials. Two representative SCM have been used in this work: slag and fly ash. Each o ...
Cement hydrates and their chemically bound water content are sensitive to changes in relative humidity (RH) and temperature. This may cause specific solid volume changes affecting dimensional properties of hydrated cement paste such as shrinkage, swelling ...
Additions of slag are usually considered to give cementitious materials which perform well in sulfate bearing environments. This paper compares the deterioration of slag cement blends to those of plain Portland cement and demonstrates that this occurs more ...
A novel clinker with low Ca/Si ratio and low sintering temperature was synthesized, and the property of the clinker was tested. A clinker sintered from industrial raw materials mainly contains rankinite (Ca3Si2O7), pseudowollastonite (Ca-3(Si3O9)) and ferr ...
This paper is the work of working group 3 of the RILEM Technical Committee on Hydration and Microstructure of Concrete with SCM (TC 238-SCM). The pore solution is an essential but often overlooked part of hydrated cements. The composition of the cement por ...
Cement is the most produced material around the world. Developing countries face a growth of population involving an increasing need of infrastructures. Due to this situation, the cement industry needs to find the best comprise between increasing the cemen ...
Supplementary cementitious materials (SCM) lower the environmental impact of cement and concrete but react more slowly than Portland cement, which therefore limits the levels of substitution possible as reasonable early strengths are necessary. One of the ...
