Incorporating an appropriate proportion of hydrated lime into a cement-based mixture improves plasticity and workability, making the product easier to handle on the trowel. Hydrated lime also increases water retention, which helps to improve the contact and bond with the substrate.
Why Add Lime to Cement?
Adding lime to cement has been common for centuries, but why is it important? Lime is a natural material often found in soil and rock formations and has been used as a binding agent since ancient times. Lime is often added to cement to improve the properties of concrete and mortar, making it more durable and resilient.
The most crucial reason why lime is added to cement is to increase the strength of the concrete. Lime is a pozzolanic material that reacts with water and calcium hydroxide to form a cementitious material. This reaction is known as the pozzolanic reaction and it strengthens the cement. When added to cement, lime helps reduce the amount of water and cement needed to make the concrete mix. This reduces the project’s cost and the time it takes to complete the project.
In addition to increasing the strength of concrete, lime also helps to improve the durability of the concrete. Lime helps reduce the rate of deterioration and cracking of the concrete surface, making it more resistant to weathering. This helps the concrete last longer and remain in better condition.
Another reason why lime is added to cement is because it can improve the workability of the concrete. Lime helps to make the concrete more
