“…The obtained results are in line with those of Carsana et al and Edwards et al [67,68]. Recent studies show that even a partial substitution of binder by ground glass in lime mortars increases the compressive strength of mortars [69]. The use of natural admixtures, such as brick dust or ground glass mixed with the selected sands increases the durability of mortars, as for example in the salt crystallization test for formulations 24 and 17.…”

This work proposes sustainability criteria for the selection or design of restoration mortars based on their physical and mechanical properties, durability, price in the French market, and the environmental impact estimated by the global warming potential. A score is assigned to the mortars based on normalized values of their physical and mechanical properties. A total of 24 formulations of restoration mortars were characterized, and their scores were compared. A case study showing the application of the proposed selection method is presented, focused on the restoration of historical monuments in Paris, France, built with Lutetian and Euville stones. In this case, hydraulic lime mortars were the most sustainable options. The application of the method is also projected for global application, as showcased for the restoration of Mayan stones in Southern Mexico.

“…The inclusion of chestnuts in the mixture containing silica and glass powder makes it possible to increase the previous results (956% and 591%, respectively), especially if the diametrical compression strength is close to the compression strength. It is great because the performance and durability mixture due to the movements of mortar that may occur throughout its life cycle will be better [7,9,37], including through UP which tends values towards more "compact" mixtures, see Figs. 5 and 6.…”

Waste reuse in buildings has proven to be an interesting alternative and more and more research is making it possible to it from many industrial sectors as raw material for making products, reducing the disposal and exploitation of natural resources. Associated with the above, the lime-based mortars in the restoration of historic buildings are since the material provides “breathability” to the substrate, facilitating the exchange of vapors due to its porosity, preventing condensation inside the masonry in addition to the low thermal conductivity, also the ability to accommodate the movements that the building may undergo over time. In this context, the objective of this work is to evaluate the physical, mechanical, chemical properties, and durability of mortars made with binder: sand: biopolymer, in the proportion 1: 3: 0.06 (by weight) where waste was added: silica fume and/or glass powder and/or crushed Amazon chestnuts. To this end, Portland cement or hydrated lime was used as a binder to provide a more in-depth analysis, also allowing the influence of this to be assessed. Mechanical tests (compressive strength and diametral compression strength), durability (immersion absorption, capillarity absorption), and ultrasonic pulse were carried out at 28 days of age. Finally, the benefits of inserting waste in the performance of the mortar were verified, mainly from Amazon chestnuts, which provided significant gains in tensile strength.

“…Cultural heritage is directly related to the general principles of sustainable growth. Therefore, heritage buildings restoration allows future generations to know and identify the history and heritage culture of cities, and the interest in this topic also includes social and economic values Innocencio et al [ 18 ], Oliveira et al [ 25 ], Ayat et al [ 5 ].…”

Lime-based mortars with added silica fume and bioproducts for restoration and preservation of heritage buildings

et al. 2023

Restoration of heritage buildings requires an appropriate choice of materials, as inappropriate materials can lead to degradation rather than preservation. Hydrated lime and sand mortars are the most suitable for masonry cladding. However, they have low durability regarding current requirements. This work investigates the use of silica fume and/or biopolymers (egg albumen and additive derived from the reuse of milk unfit for human consumption (complexes of whey protein with κ-casein) in producing these mortars. Some mortars were characterized by mechanical properties (compressive and diametric strength, absorption rate) and chemical properties (SEM, Infrared spectrum). The research revealed that silica fume addition allows an increase of more than 50% in the mechanical strength of the mortars when associated with animal protein. The value may be higher than 60%, especially for biopolymers (complexes of whey protein with κ-casein). Finally, the proteins in the mortar mixture provide intense air entry that results in the formation of more pores. This increase in voids allows more CO 2 to enter, directly contributing to a faster carbonation process and performance mortar.
