High Purity Lime as an Ecologic Alternative for Construction Mortars and Pastes

Abstract

Limestone is one of the most ancient construction materials that exist, however it has become obsolete over the last decades, being replaced by industrial materials like cement. It must be considered that not only the construction lime can be used in works, but the limestone industry can provide other products like high purity lies The research about the surface area of high purity lime has verified that it exists an improvement in the adhesion and workability features of the material in comparison with construction lime, besides to be a more economical solution than masonry cement. It is proposed in this document the use of high purity lime in construction works to achieve the benefits previously mentioned. Various samples with different percentages of high purity limes were tested in the laboratory, analysing the surface area changes between them, considering its use for construction purposes and its performance.

Physical and Mechanical Characterization of Lime Pastes and Mortars for Use in Restoration

“…The purpose of this test is to determine the surface of the material in m 2 /g; with larger areas, we obtain higher reactivity [36]. The samples were analyzed in the Institute for Research in Metallurgy and Materials, at UMSNH, in Horiba equipment Model SA9601 STNE, MO (see Figure 4).…”

“…Therefore, the mixtures can be better agglomerated, making them more workable and adherent to the surfaces. Previous research works in the laboratory allowed us to characterize the surface area of lime specimens [36], as is shown in Table 7. The surface area of SL is the highest of all, so its workability and adherence characteristics are the best, and this is the reason why restorers have used it for centuries.…”

Compressive Strength and Ultrasonic Pulse Velocity of Mortars and Pastes, Elaborated with Slaked Lime and High Purity Hydrated Lime, for Restoration Works in México

“…In recent years, researchers and constructors have tried to recover the traditional systems and materials; the problem is that this traditional knowledge has been lost except for few lime manufacturers, which had transmitted generationally the ancient techniques [5]. However, out of the restoration field, slaked lime is not applied in other works, as other types of lime are used, mainly the construction lime.…”
