This paper deals with the mixture design of 3D printable concrete (3DPC) based on the
theoretical analysis of the yield stress of mortar. It has been found that there is a linear …

A high calcium fly ash with high SO 3 content was used to produce high performance concrete.
In all the mixes, the fly ash contents of 50% and 60% by weight were applied. Although fly …

Three-dimensional (3D) printing construction techniques have been increasingly developed
in recent years and transferred into practical applications in some instances. However, …

In the present study, the early-age reaction process of alkali-activated slag (AAS) pastes was
in-situ monitored by using embedded piezoelectric transducer based ultrasonic monitoring …

Calcium–silicate–hydrate (C–S–H) gel, the main product of cement hydration, contributes
the most to engineering properties of concrete. Hence, the microstructural physical and …

The effect of chloride concentration and pre-passivation on the pitting corrosion resistance
of low-alloy steel and conventional low-carbon steel in simulated concrete pore solution was …

Over the past decade, 3D concrete printing has shown enormous application potential for
the industry. The new technology poses specific requirements on 3D printable concrete (3DPC)…

As the only method for all-weather, all-time and long-distance target detection and
recognition, radar has been intensively studied since it was invented, and is considered as an …

Printability is a key parameter that affects the application of foam concrete to 3D printing. In
this study, the hydroxypropyl methylcellulose (HPMC) and silica fume (SF) were doped into …

To modify the adsorption performance of Ti 3 C 2 T x MXene, we report a facile approach to
expand the interlayer spacing of Ti 3 C 2 T x and to tune its surface functional groups by hot …
