Magnesium-based cement such as magnesium silicate hydrate (M−S−H) has drawn interest as a substitute for ordinary Portland cement. The precise determination of M−S−H's elastic modulus is essential in assessing the mechanical performance of M−S−H-based concrete. Atomic force microscopy (AFM) allows for spatially resolved quantification of nanomechanical characteristics of materials, including thin overgrowths on substrates. In this study, elastic modulus maps of M−S− H grown on single crystal mica surfaces were obtained using amplitude modulation−frequency modulation AFM. The effects of the Mg-to-Si molar ratio and morphology on the elastic modulus of M−S−H films were investigated. AFM reveals elastic moduli ranging from 5 to 15 and 40 to 64 GPa, depending on the growth reaction time and morphology. A comparison with calcium silicate hydrate found in traditional cement reveals insights into the influence of silicate polymerization on the material's stiffness. These findings demonstrate the effectiveness of AFM in quantitatively describing the mechanical characteristics of cementitious phases and suggest that M−S−H cement has the potential for use in a variety of construction applications.

“…The problem is the degradation of the quenched lime material, which requires special handling when making the mortar mixture (Karatasios et al, 2008). The mixture's reliability has been tested through physical and mechanical characteristics approaches, limited to the compressive and tensile tests of the binder (Demiral et al, 2022;Hajj & Bhasin, 2018;Jiang et al, 2023;Zdeb et al, 2022;Y.

This study aims to determine the shear strength and flexural strength of red brick masonry, determine the effective thickness of calcium hydroxide mortar with a mixture ratio of 1Kp:2Ps, and determine the failure pattern of red brick masonry due to the load received during the direct shear strength test and flexural strength test. The research was conducted by experimental method. The tests carried out were the direct shear and flexural strength tests. Variation of successive mortar thickness of 10mm, 15mm, and 20mm. The test object is 18 (eighteen), the thickness variation consists of 3 test objects. Data analysis used descriptive quantitative by finding the average value of the shear strength and flexural strength. Based on the test results, the average compressive strength and splitting tensile strength of the mortar were 0.613 MPa, 0.0414 MPa. The average shear strength with a 10mm; 15mm; and 20mm is 0.025 MPa; 0.020 MPa; and 0.016 MPa, respectively. The flexural strength of mortar thickness with 10mm, 15mm, and 20mm are 0.034 MPa; 0.045 MPa; and 0.041 MPa, , respectively. In the masonry shear test, the effective thickness of the mortar was found at 10mm with a maximum shear strength of 0.025 MPa, while in the flexural test, the effective thickness of the mortar was found at a thickness of 15mm with 0.045 MPa. The pattern of failure in red masonry's shear strength and flexural strength tests is the mortar failure.
