Shrinkage cracks pose significant challenges to the long-term durability of concrete
structures, and it can be effectively address by incorporating various types of fibres …

Plastic cracking is probably one of the earliest defects for concrete structures, and is capable
of reducing a structure's durability and service life if not prevented. Over the last 60 years …

This study investigates the effects of nano silica (NS) and micro steel fiber on the properties
of ultra-highperformance concrete (UHPC). The experimental consists of three groups, each …

Abstract 3D printed concrete is vulnerable to severe early age shrinkage-related cracking
due to the absence of formwork and coarse aggregates. To address this, several potential …

Superabsorbent polymers (SAP) are a new, promising class of chemical admixtures which
offer new possibilities in respect of influencing the properties of cement-based materials in …

In concrete, early age pore water evaporation results in volumetric shrinkage that, if
restrained, can cause plastic shrinkage cracking (PSC). 3D printed concrete (3DPC) is …

Providing additional water to the hydrating cementitious particles is essential to achieve the
optimal mechanical performance of the low w/b concrete mixes preferred for 3D printing …

The utilization of electronic plastic waste (EPW) as a substitute for traditional aggregates in
concrete has gained attention for its potential to reduce environmental waste. However, the …

Supplementary cementitious materials were incorporated into hydrogel-based internal
curing agents to improve the hydration, microstructure, and ultimately strength of internally …

Structural cracks are the major cause of structural failure and significantly impact their
strength and durability. Bacterial self-healing concrete as a sustainable structural Smart …
