Durability of shotcrete for underground support– Review and update
TL;DR: In this paper, the authors shed light on the durability of shotcrete by revising the literature, highlighting what is missing and needs to be addressed, assessing how the knowledge about concrete durability can be transferred to shotcrete, and providing recommendations for durable shotcrete structures.

Understanding of the deterioration characteristic of concrete exposed to external sulfate attack: Insight into mesoscopic pore structures
TL;DR: In this article, the mesoscopic pore structures in concrete were investigated under different types of sulfate exposure, such as chemical sulfate attack (CSA) and physical sulfate attacks (PSA), using a nondestructive testing technology.
Journal ArticleDOI
Effects of curing methods of concrete after steam curing on mechanical strength and permeability
TL;DR: In this paper, the compressive strength, non-evaporable water content and permeability (air, water and ion) of steam-cured concrete were tested under different subsequent curing conditions.
Journal ArticleDOI
Effects of metakaolin on the mechanical and anticorrosion properties of epoxy emulsion cement mortar
TL;DR: In this article, different sizes of metakaolin were introduced into epoxy resin emulsion concrete mortar (EECM) to improve mechanical and anticorrosion properties, and the effects of MK contents and sizes on the mechanical property, water absorption and chloride diffusion coefficient of EECM were studied respectively.
Journal ArticleDOI
Direct shear behavior of sulfate-exposed shotcrete: Experimental and modelling research
TL;DR: In this article, a sulfate-damage shear model was proposed for shotcrete specimens considering the effects of normal stress and sulfate exposure time and the Mohr-Coulomb (M-C) criterion was used to calculate the nominal cohesion and nominal internal friction angle.

Resistance of concrete and mortar against combined attack of chloride and sodium sulphate
Mathias Maes,Nele De Belie +1 more
TL;DR: In this paper, the reciprocal influence of Cl− and SO42− was investigated for four mixtures, namely with Ordinary Portland Cement, High Sulphate Resistant cement, and with Blast-Furnace Slag (50% and 70% cement replacement).
Journal ArticleDOI
Resistance of concrete against combined attack of chloride and sulfate under drying-wetting cycles
TL;DR: In this article, the combined solution of chloride and sulfate was investigated for three different mixtures, including fly ash and slag, and the results indicated that OPC specimens showed bigger deterioration compared with specimens with slag exposed to combined solution attack under drying-wetting cycles.
Journal ArticleDOI
Concentration dependence of diffusion and migration of chloride ions: Part 1. Theoretical considerations
TL;DR: In this article, the chloride ion diffusion and migration processes in concentrated solutions are theoretically analyzed and the quantitative relationship between diffusion coefficient and migration coefficient is established, and the theoretical analysis shows that the effective chloride diffusion coefficient determined from the conventional diffusion or migration tests is not a constant, but rather is a complicated function of concentration.

Thaumasite sulfate attack on concrete: Mechanisms, influential factors and mitigation
TL;DR: In this article, a mitigation strategy for faasite sulfate attack on concrete is proposed based on the balance of physical and chemical resistances of concrete as controlled by key mixture design parameters.

Properties of wet-mixed fiber reinforced shotcrete and fiber reinforced concrete with similar composition
TL;DR: In this article, various properties of fiber reinforced shotcrete (FRS), including compressive strength, flexural behavior, permeability and shrinkage behavior, are compared with FRC of similar composition.
