This study investigated the influence of ordinary Portland cement (OPC) and reactive non-reactive mineral additives on characteristic microstructure mechanical performance ultra-high-performance, strain-hardening cementitious composites (UHP–SHCCs). Nine mixes were considered composed materials, such as ground granulated blast furnace slag (GGBS), silica fume (SF), kiln dust (CKD), flour. Compr...

In the last decade, nanomaterials made a major breakthrough in concrete industry by providing with unique properties. Earlier studies have shown improvement early strength of that can accelerate construction process. this study, 1% and 2% nano-silica were added to mixtures contain 30% 70% ground granulated blast-furnace slag (GGBS). Adding GGBS mixture showed an increase compressive 13.5%, 7.8%...

Abstract Most construction projects face the problem of a high percentage gypsum in soil. To get rid unwanted effects gypsum, which lead to dissolution presence water and settlement foundations buildings subsoil roads, researchers used several materials that can be added soil improve its properties resisting loads. This research presents study effect adding cement kiln dust (CKD) ground-granula...

Utilisation of fly ash and Ground Granulated Blast Slag as an alternative material in concrete reduces the use of OPC in concrete. Evolution of geopolymer concrete cured at ambient temperature broadens its suitability and applicability to concrete based structures. This paper presents the mix proportions and outcome of an experimental study on the density and compressive strength of geopolymer ...

The current cement industry has several environmental and social problems, including high greenhouse gas emissions, air pollution, water consumption, the generation of large quantities waste. This matter grown into a significant concern, there is now pressing requirement to substitute conventional binding material in concrete, namely Ordinary Portland Cement (OPC). paper presents report on hybr...
