“…This confirms that increasing the block strength increases its compactness, consequently reducing the water absorption, as reported in the literature (PARSEKIAN et al, 2019). This behaviour was also reported by other authors for compressive strengths different from those found in the current work (MARTINS et al, 2018;FONSECA et al, 2019). Since the adhesion between the mortar and the block can be largely affected by the mechanical bonding provided by the mortar penetration into the block pores, this trend may lead to progressive reductions in adhesion as the block strength increases, as discussed later.…”

“…Izquierdo (2015) evidenciou que quando a utilização do graute é feita quanto maior sua resistência característica maior é a aderência do bloco com concreto quando se trata de alvenaria estrutural armada. Já Martins et al (2018) destacou que a utilização do graute de maneira vertical é diretamente ligada com a resistência do prisma. Quanto maior a resistência à compressão dos grautes de preenchimento maior a resistência do prisma, evidenciado também pelo presente trabalho.…”

“…MARTINS et al [25] estudaram a influência que a resistência dos blocos de concreto e o grauteamento exerceram na rigidez e resistência à compressão de prismas com duas unidades. Foram consideradas três classes de resistência para os blocos (4,5; 8 e 12 MPa na área bruta), três traços de graute (15, 20 e 25 MPa) e três traços para argamassa (5,8; 10,4 e 15,5 MPa).…”
