By lime mortars we understand a mixture of one or more binders where one of them is always lime, aggregates, water and sometimes additions and/or additives. These mortars have application in both restoration works and new construction. The use of this type of mortar is very wide, among its main applications we can find: Interior and exterior coatings (plaster, plaster...) either in: rehabilitation works since they are highly compatible with traditionally used systems. in new construction with the aim of improving habitability conditions. In execution and repair of factories and walls. Application for structural reinforcement and consolidation of masonry walls, pillars and vaults by low pressure injection.
Also important is its use in repairing and filling joints in both brick and natural stone walls, for example. Depending on the type of mortars, they are characterized by : Pure lime mortars Good plasticity and workability. No retraction Great elasticity Volume constancy under varying humidity conditions. Appreciable permeability to water vapor. Avoid condensation. It does not cause Paraguay Email List efflorescence due to the absence of soluble salts. Good thermal and acoustic insulation Allows for thinner layers Easy to color They guarantee sealing and coating. Good resistance to rainwater penetration Natural disinfectant and fungicide product due to the alkalinity of lime. Fireproof product that does not emit toxic gases.
Mixed lime and cement mortars Greater adhesion Greater plasticity Increased vapor permeability Reduction of efflorescence Less shrinkage and cracking Depending on the characteristics of the cement used and the quantities used, the properties of the mortar will vary greatly, especially in setting times and shortterm mechanical resistance. As recommendations for its application , we can distinguish the following: Use the mortar within minutes of mixing. Do not apply below ºC or above ºC. Do not apply at risk of frost, rain, strong winds and in case of extreme weather conditions of wind or high temperatures, water the product by gentle sprinkling the day after application. Moisten the wall abundantly.
