“…Other mechanical parameters must be met to achieve the minimum standards for classifying mortar coating materials, including flexural and shear strength (Abdollahnejad et al, 2021;Binda et al, n.d.;Reza Nadi Abiz et al, 2023). This needs to be done to provide information related to the quality of the mixing material using certain formulations to obtain optimal proportions that can be recommended for repairing cultural heritage buildings (Arioglu & Acun, 2006;Pacheco-Torgal et al, 2012;Válek et al, 2019) especially since Indonesia is a country with high earthquake intensity, so it requires special handling.…”

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.

This study investigates the substantial impact of nanoparticle aggregation on the tensile strength of nanocomposite materials. Nanoparticles measuring between 10 nm and 30 nm were examined using deliberate controlled agglomeration. The smallest agglomeration size was 10 nm, while the largest was 30 nm, indicating a 200% increase in agglomerate size based on the characterization data. The equally dispersed nanoparticles in the control group also measure an average tensile strength of 53MPa from the tests conducted. On the other hand, observed that the tensile strengths of nanocomposites with introduced agglomerates were lower. In the current study, a 34% reduction was observed for samples with agglomerates of 30 nm to a value of 35 MPa from the control. On the other hand, the sample prepared with the agglomerates of size 10 nm and 15 nm provided 50 MPa and 45 MPa of strength, respectively. Outcome shows that tensile strength is in negative correlation with the size of agglomeration and therefore, yield that the larger agglomerate reduce the mechanical properties of the nanocomposites. This study stresses that the agglomeration has to be regulated, and how the formation of nanoparticle clusters have a negative impact on the tensile strength of the nanocomposites, in order to enhance the mechanical properties of nanocomposite materials. These findings are useful in planning improved nanocomposites with improved mechanical properties for use in a wide-range of applications in engineering.

Nanomaterials have emerged as crucial components in enhancing drilling cement properties, garnering significant interest from researchers and the drilling industry. Previous studies have explored nanoparticles, carbon nanotubes, and cellulose nanofibers, revealing their ability to improve mechanical strength, bonding, sulfate resistance, thermal stability, and rheological properties while reducing setting time, porosity, and permeability. This research delves into fundamental variables impacting nanomaterial-infused cement quality, including types, concentrations, and environmental conditions like temperature and pressure. Results underscore the substantial performance enhancements achievable through nanomaterial additives, fostering operational efficiency in drilling. Moreover, the study identifies potential drawbacks of certain nanoparticles and establishes optimal dosages for cement formulations, aiding drilling engineers in refining their approaches. Additionally, the investigation extends to the combined use of nanomaterials in hybrid and composite forms, offering insights into further enhancing drilling cement quality. Ultimately, this research advances our comprehension of nanomaterial effects on construction materials and drives technological progress in drilling by optimizing their utilization.
