The hydraulicity of the hydraulic lime is mainly due to _____.a)calciu...
Clay imparts hydraulicity to the lime and makes it insoluble in water, if it is in excess it arrests slaking if it is in deficiency it retards slaking.
Presence of sulphur in small quantity reduces the slaking and accelerates the setting process of lime.

Hydraulicity of Hydraulic Lime:
Hydraulic lime is a type of lime that possesses hydraulicity, which means it sets and hardens when mixed with water. The hydraulicity of hydraulic lime is mainly due to the presence of clay in it.
Explanation:
Hydraulic lime is produced by burning limestone containing clay and other impurities at a temperature of 1200-1300°C. During the burning process, the limestone decomposes to form calcium oxide (CaO) and carbon dioxide (CO2). The clay present in the limestone acts as a catalyst and reacts with the calcium oxide to form calcium silicates and aluminates. These compounds possess hydraulicity, which means they react with water to form insoluble compounds that harden and set.
The clay content in hydraulic lime plays a crucial role in its hydraulicity. The clay impurities in the limestone react with the calcium oxide to form hydraulic compounds. The clay content in hydraulic lime varies from 5-25% by weight, depending on the source of the limestone.
Conclusion:
In conclusion, the hydraulicity of hydraulic lime is mainly due to the presence of clay in it. The clay impurities in the limestone act as a catalyst during the burning process and react with the calcium oxide to form hydraulic compounds. These compounds possess the ability to harden and set when mixed with water, making hydraulic lime an essential material in the construction industry.
