Sulphate attack resistance of high-performance concrete

2013-7-7  Jin et al. (2008), Chen and Jiang (2009), and Gao et al. (2013) studied sulphate attack coupled to flexural loading and showed that the flexural load accelerated concrete deterioration; however, using a low water-to-binder (w/b) ratio or mixing approximately 20% fly ash into the concrete increased the concrete resistance.

Sulphate attack resistance of high-performance concrete

2017-8-27  It has long been recognised that sulphate attack usually results in the formation of expansive products, such as ettringite, gypsum and thaumasite, which are produced by sul- phate ions reacting with hydration products in cement, resulting in expansion, cracking, spalling, and concrete strength loss (Gonzáles and Irassar, 1997; Tian and Cohen, ...

Long-term sulfate resistance of synthesized cement

1.Introduction. The longevity of a concrete structure depends on its durability against chemical sulfate attack, among other factors. This phenomenon occurs when water-soluble sulfate ions, commonly originating from sulfate-bearing soil, water (e.g. groundwater, river water, seawater) or wastes , interact with the hardened cement paste.In the aftermath, expansive ettringite

Sulfate Attack - an overview ScienceDirect Topics

Sulfate attack is another possible deterioration mechanism of concrete. It can have endogenous origin (developing without any contribution from the environment) or exogenous origins (such as sulfates contained in the soils or in liquids) (Germain, 2008; Neville, 2004).In both cases, the consequence is some volume expansion owing to the delayed formation of ettringite, which is
