Influence of Internal Sulfate Attack on Some Properties of Self Compacted Concrete
Journal of Engineering, 2017 Self-compacted concrete (SCC) is a highly flowable concrete, with no segregation which can be spread into place by filling the structures framework and permeate the reinforcement without any compaction or mechanical consolidation ACI 237R-14.

Influence of Internal Sulfate Attack on Some Properties of High Strength Concrete
Journal of Engineering, 2015 One of the most important problems that faces the concrete industry in Iraq is the deterioration due to internal sulfate attack , since it reduces the compressive strength and increases the expansion of concrete. Consequently, the concrete structure may

Cement and Concrete Research, 1988 Abstract This paper compares the effects of chemical attack on portland cement mortar from internal and external sulfate sources. Factors such as cement type, cement content, water to cement ratio, and addition of fly ash are studied with respect to expansion and strength development and it is found that substantial differences exist between the two ...

Behavior of Steel-Fiber Reinforced Lightweight Self-Compacting Concrete Containing LECA after the Exposure to Internal Sulfate Attack [PDF]
E3S Web of Conferences, 2023 For many years, lightweight concretes (LWC) have been utilized successfully in the construction of buildings because of their low specific weight, high thermal insulation capacity, and sound insulation.

Preparation of concrete specimen for internal sulfate attack analysis using electron backscatter diffraction [PDF]
International Journal of Applied Ceramic Technology, 2022 Abstract Concrete cores were obtained from houses in eastern Connecticut, USA, that had varying degrees of crumbling foundations and wall cracking. Electron backscatter diffraction (EBSD) was used simultaneously with energy dispersive X‐ray spectroscopy to investigate the degradation of these samples.
