In order to compensate the shrinkage of cement-based grout after hardening, volume
expansion was produced by adding sodium sulfate or gypsum into aluminum powder …

The aim of this research is to predict preplaced-aggregate concrete (PAC) compressive
strength (CS) by using machine learning approaches such as gene expression …

To ensure excellent rheological behavior, penetrability and mechanical property of microfine
cement (MC) grout in the field work, it is essential to obtain and control its property by …

In recent years, research and development of geopolymers has gained significant interest in
the fields of repairs and restoration. This paper investigates the application of a geopolymer …

The utilization of ultra-high-performance concrete (UHPC) permanent formwork could
facilitate the construction of hydraulic concrete structures. However, the joints between …

Microbially induced carbonate precipitation (MICP) has emerged as a promising solution in
enhancing the durability of concrete structures in the recent decade. Bio-grout is generally …

This study investigated the influence of fluorogypsum and KH 2 PO 4 on the mechanical
properties and hydration mechanisms of aluminate cement based grouting materials …

Using mineral additives and admixtures as self-healing agents in cement-based composites
has been extensively researched. However, if the minerals are added directly to the …

The aim of this study is to develop a nano TiO 2-modified geopolymer grout and to confirm
application in damaged beam-column joints (BCJs). The experimental study was planned in …

This paper studies the feasibility of replacing fly ash in cement-based grouting material with
gold tailings after compound activation. Through mercury intrusion porosimetry (MIP), X-ray …
