Evaluation of Physical Salt Attack on the Mechanical Properties of Spun Concrete

Abstract

The article's main focus is on spun concrete created with various chemical admixtures and subjected to prolonged contact to salt-saturated ground water that is hostile and a cyclical temperature gradient. 64 prismatic spun concrete specimens were processed several times (75–120 times) throughout the course of an extended experimental study under a variety of harsh environmental conditions. Drying was place at a temperature of 45 to 50 °C after prismatic specimens had been soaked in water or saline. It was discovered that the physical salt assault and temperature gradient's long-term multi-cycle effects on concrete's compressive strength, Young's modulus, and durability were detrimental. However, chemical admixtures enhanced the structure of spun concrete, greatly enhancing its physical-mechanical characteristics and durability.
