X-ray computed tomography (CT) is a non-destructive technique that offers a 3D insight into
the microstructure of thick (opaque) samples with virtually no preliminary sample …

With the deterioration and ageing of concrete structures, repair and rehabilitation have
emerged as one of the most critical activities associated with high maintenance costs. One of …

With the extension of service time, infrastructure is in growing urgency for repair and
reinforcement due to its deterioration in safety and durability over the years. Normal cement …

An aqueous epoxy resin with four different dosages was employed to enhance ordinary
Portland cement (OPC) mortar for the first time used as a polymer-cement repairing material …

The utilization of fly ash in concrete production can reduce pollution as well as decrease
greenhouse gas emission. However, a high replacement ratio of cement with fly ash largely …

The formation of the interpenetrating polymer network (IPN) structure within the cement-
polymer system has been revealed by experiments from 2 dimensional to 3-dimensional …

Ordinary silicate cement repair materials are slow to set and harden, have low early
strength, and cannot meet the demands of rapid repair, and the disadvantage of brittleness …

Geopolymer with great durability and bonding properties, as a kind of low-carbon
cementitious material, has become a potential repairing material for concrete repair. In this …

This paper conducted a comprehensive investigation into the role of polymers in cement-
based materials. First, the modification mechanism of polymers on cement-based materials …

To improve the delayed effect of waterborne epoxy resin (WEP) on cement hydration and
improve the early compressive strength of the composite paste. Nano-SiO 2 (NS) modified …
