## TL;DR

This paper presents a dataset showing how ions in mine water affect the strength and structure of Portland cement.

## Contribution

The study provides a systematic experimental dataset on the effects of sulfate, magnesium, and bicarbonate ions on cement properties.

## Key findings

- Compressive strength tests reveal the impact of ions on cement's mechanical properties.
- XRD and SEM analyses show microstructural changes due to ionic exposure.
- The dataset aids in understanding long-term cement behavior in mine water environments.

## Abstract

The dataset presented in this paper comprises compressive strength test results for PO42.5 Portland cement mixed with mine water containing sulfate, magnesium, and bicarbonate ions. The tests are designed to systematically assess the impacts of these ions, both individually and in combination, on the long-term mechanical properties of PO42.5 Portland cement. Furthermore, X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses were conducted to investigate the microstructural characteristics of the cement-based materials under varying ionic influences. This dataset offers significant insights into the compressive strength development of cementitious materials in environments with sulfate, magnesium, and bicarbonate ion exposure.
