Development of Next-Generation Construction Materials with Graphene Additives
The developments of ordinary Portland cement (OPC) composites and alkali-activated binder composites have attracted significant attention in the past decade. Different technologies have been proposed to address current drawbacks of these construction materials (e.g. low tensile strength, flexural …

A review on the efficiency of different supplementary cementitious materials as a partial replacement for Portland cement in concrete
The effects of global warming and climate change are important and have attracted the attention of many researchers. Global warming is a result of the presence of increasing amounts of greenhouse gases in the atmosphere. Carbon dioxide, which is largely emitted into the atmosphere during the …

Admixture compatibility and freeze-thaw resistance of concrete prepared using commercially produced limestone calcined clay cements
Admixture compatibility and fresh, hardened, and durability properties of mortars and concrete prepared using commercially produced limestone calcined clay cements (LC3s) were evaluated during this study. Incompatibility was evaluated for commercially available high range water reducers (HRWRs) and …

An experimental study of high-performance concrete using metakaolin additive and polymer admixture
… in the use of supplementary cementing materials and polymers to produce high-performance concrete. Utilizing a mineral substance as cement replacement in concrete has less environmental pollution and greatly increases the service life of the concrete structures due to improve the most of concrete …

Powder packing optimisation for clinker reduction in concrete
… be reduced without compromising desired concrete properties. Existing methods for clinker reduction have, however, only allowed clinker replacement to a limited extent. This research investigated the more efficient use of clinker to minimise clinker content required to achieve desired mechanical …
