摘要:Hydrated lime, due to its life cycle (return to the natural form as
a result of binding and hardening) shows a positive ecological aspect.
The binder is often used in building materials based on plant components
due to the high alkaline reaction and low diffusion resistance, as well as in
mortars and plasters. However, it is an air binder with low strength
parameters and the process of its binding and hardening is long-lasting.
One of the ways to accelerate the binding processes and also to increase the
strength of the binder is the use of additives in the form of pozzolanic
materials which react with calcium hydroxide and form compounds with
hydraulic properties. These are natural materials or industrial waste, so
they do not affect the environmental impact of lime binder. The article
presents the influence of the addition of pozzolan (three types) in various
weight amounts, on the strength properties of mortars, their absorbability
and capillary rise (presented as water absorption coefficient). The influence
of pozzolan presence on workability of fresh mortars - their consistency
was also checked.
