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.

“…Numerous studies [24,27,[29][30][31] have examined the impact of glycerin on the thermal properties and mechanical performance of concrete. Researchers [30] have shown that glycerin-based PCM can effectively reduce indoor temperature uctuations [32], lower energy consumption for heating and cooling [33], and enhance occupant comfort in buildings through experimental analyses and numerical simulations [34].…”

This study investigates the influence of Glycerin content, water-to-binder (w/b) ratio, and concrete grade on the thermal and mechanical properties of concrete incorporating Glycerin as a phase change material (PCM). M20, M30 and M40 grades of concrete were studied using 0.40, 0.45 and 0.50 w/b ratios. The amount of Glycerin varied from 0 %, 2.5 %, 5.0 %, 7.5 % to 10 % and compressive strength was studied on 7, 28, 56 and 90 days. The slump values decrease with increasing glycerin content, especially at higher w/b ratios, with M20 concrete exhibiting the lowest slump due to its lower grade. Maximum compressive strength is achieved at 5% glycerin content across all mix categories, with a w/b ratio of 0.45 yielding the highest strength. Glycerin content affects the thermal properties, while the w/b ratio significantly influences thermal conductivity. Glycerin content has the most significant impact on thermal diffusivity and specific heat capacity. The interaction between glycerin dose, w/b ratio, and concrete grade is analyzed using Response Surface Methodology (RSM), revealing complex dependencies among these factors. These findings contribute to understanding the behavior of glycerin-modified concrete and provide insights for optimizing its thermal and mechanical properties in construction applications.
