Control of Viscosity of Cementitious Materials Using Waste Limestone Powder

International Journal of Concrete Structures and Materials, 2019
Ultra high performance cementitious materials possess high solid volume fraction by a decreased water-to-binder ratio. The use of a high-range water reducing admixture allowed us to obtain the initial fluidity of ultra-high performance cementitious ...

Diatom biosilica as a supplementary cementitious material

npj Materials Sustainability
Abstract The use of supplementary cementitious materials (SCMs) is a key method used to reduce the embodied carbon of cement-based materials. Uncertainty in traditional SCM markets has led to increased interest in alternative, natural SCM materials.

Can superabsorbent polymers mitigate shrinkage in cementitious materials blended with supplementary cementitious materials? [PDF]

, 2016
A promising way to mitigate autogenous shrinkage in cementitious materials with a low water-to-binder ratio is internal curing by the use of superabsorbent polymers.

Heat-induced phase transitions in mining tailings to create alternative supplementary cementitious materials

Resources, Conservation and Recycling
The present study investigated the mineralogical changes in five different mining tailings (i.e., bauxite, gold, copper, and lead) with varying heating conditions (i.e., non-heating, 600 ◦ C, and 900 ◦ C) to explore the feasibility of using thermally ...

Reactivity of supplementary cementitious materials (SCMs) in cement blends

Cement and Concrete Research, 2019
Supplementary cementitious materials (SCMs) are key components of sustainable, low carbon cements. To maximize their use in blended cements, the impact of SCMs on cement hydration needs to be understood and accurately captured by models.
