Efficient maintenance and upgrading of a building during its lifecycle are difficult because a cementitious finish uses materials and parts with low disassembly properties. Additionally, the reuse and recycling processes during building demolition also present numerous problems from the perspective of environmental technology. In this study, an induction heating (IH) method was used to disassem...

Synopsis: Cementitious materials are generally classified as semi-conductors that are capable of carrying electricity when an external electrical signal is applied. The electrical properties of cementitious materials have been widely explored for monitoring their internal hydration processes. However, comparatively less work has been done in using the inherent electrical properties of cementiti...

Designing self-healing into cementitious materials can open a new world of opportunities for resilient concrete infrastructure under service loading conditions. The self-healing process should be robust as well as repeatable, allowing for self-repair after multiple damage events. The repeatability poses great challenges when self-healing strategies mainly rely on the formation of low-strength c...

Synopsis: This article reviews the recent advances in the research of Engineered Cementitious Composites (ECC), a class of microstructurally tailored fiber reinforced cementitious composites. The design basis, the processing routes, and some ECC performance characteristics in structural applications are highlighted. This article is dedicated to Professor Surendra Shah, in honor of his seminal c...

Cement-based materials are widely used in the construction of civil infrastructure systems. However, normal wear-and-tear and extreme loading can result in the damage and deterioration of such important civil structures. In this study, a novel approach to the detection of cracks in fiber reinforced cementitious composites (FRCC) is proposed. The approach is based upon the electrical properties ...

In this paper, a stochastic finite element method (SFEM) is employed to investigate the probability of failure of cementitious buried sewer pipes subjected to combined effect of corrosion and stresses. A non-linear time-dependant model is used to determine the extent of concrete corrosion. Using the SFEM, the effects of different random variables, including loads, pipe material, and corrosion o...

Semi-flexible pavement surfacing is a composite pavement that utilizes the porous pavement structure of the flexible bituminous pavement, which is subsequently grouted with appropriate cementitious materials. This study aims to investigate the compressive strength, flexural strength, and workability performance of cementitious grout. The grout mixtures are designed to achieve high strength and ...

The new Concrete Society Publication, Cementitious Materials, CSTR74, covers the effects of cementitious materials blast furnace slag (GGBS), fly ash (FA), limestone fines and silica fume (microsilica) on the properties of concrete. This paper focuses on the effects of silica fume on all the main properties of concrete in the fresh and hardened state as defined in the publication.

An extrusion process especially designed for extrusion of pipes made from fiber reinforced cementitious materials has been developed at Department of Structural Engineering and Materials at the Technical University of Denmark. Engineered Cementitious Composite (ECC) materials have been developed in recent years at Department of Civil and Envirionmental Engineering, University of Michigan. These...

Inorganic Phosphate Cement (IPC) is a new cementitious material, developed at the Vrije Universiteit Brussel (VUB), which sets at room temperature. Due to its non-alkaline environment during and after setting and hardening, IPC can be combined with glass fibre reinforcement. Such a textile reinforced cementitious is an interesting material in those applications where high load-bearing capacity,...
