Resumo(s): | In masonry constructions, the choice of mortar composition is usually guided by requirements of the final application, which could range from new constructions to conservation projects. Often, lime and cement are combined together, to overcome their individual shortcomings and consequently serve as a suitable binder in masonry mortars. Depending on their proportion in the mixture, it may be possible to obtain a desired range of characteristics in different mechanical properties like strength and stiffness. However, existing studies exploring this subject are scarce. Therefore, this work aims at adopting a systematic approach to studying the effect of different lime-cement ratios on the mechanical properties of masonry mortars, specifically targeting a discussion on E-modulus and fracture energy. Three distinct mixes with quantities of lime varying from 25% to 67% (by volume) have been studied. The benefits and trade-offs associated with substitution of different quantities of cement with lime in mortars, have been explored with regard to resistance to crack propagation. |
