Abstract
A method of making a chemical-resistant concrete composition, namely a quartz-based casting composition, is provided. The quartz-based casting composition provides excellent resistance to attack by chemicals, including weak and strong acids. The quartz-based casting composition is useful as concrete in various construction applications where corrosion resistance is needed. The casting composition includes a dry component and a wet component. The dry component includes about 25% to about 100% by weight quartz and the corrosion resistance increases with increasing quartz content.
Claims20
A method of making a chemical-resistant concrete composition, comprising the steps of:
- providing a dry component including about 25% to about 100% by weight quartz, zero to about 25% by weight gravel and zero to about 50% by weight concrete sand;
- providing a wet component including about 30% to about 60% by weight colloidal silica particles and about 40% to about 70% by weight water;
- and
- mixing the dry component and the wet component together to form the chemical-resistant concrete composition;
- wherein the chemical-resistant concrete composition includes about 65% to about 97% by weight of the dry component and about 3% to about 35% by weight of the wet component.
A method of making a chemical-resistant concrete composition, comprising the steps of:
- providing a dry component including at least about 85% by weight quartz and, optionally at least about 1% by weight microsilica;
- providing a wet component including about 30% to about 60% by weight colloidal silica particles and about 40% to about 70% by weight water;
- and
- mixing the dry component and the wet component together to form the chemical-resistant concrete composition;
- wherein the chemical resistant concrete composition includes about 65% to about 97% by weight of the dry component and about 3% to about 35% by weight of the wet component.
