Laminated veneer lumber is taken as an object of study, and use LVL specimens of different sizes for compression test and tensile test. The goal of the experiment is to investigate the size effect on compressive strength and tensile strength as well as the influence of the secondary glued laminated face, which appears in the secondary molding processes. The results show that both compressive strength and tensile strength have the size effect apparently and the existence of the secondary glued laminated face lower the compressive strength of LVL specimens. Afterwards, the relationship between compressive strength and volume along with tensile strength and area are obtained by the test results.

The Relationship

This article investigates the development of the following material properties of concrete with time: compressive strength, tensile strength, modulus of elasticity, and fracture energy. These properties were determined at seven different hydration ages (18 h, 30 h, 48 h, 72 h, 7 days, 14 days, 28 days) for four pure cement concrete mixes totaling 336 specimens tested throughout the study. Experimental data obtained were used to assess the relationship of the above properties with the concrete compressive strength and how these relationships are affected with age. Further, this study investigates prediction models available in literature and recommendations are made for models that are found suitable for application to early age concrete. Results obtained indicate that the relationship between the splitting tensile strength and concrete compressive strength can be approximated with a power function between 0.7 and 0.8, and this correlation is not affected by age. Fracture energy of the concrete and modulus of elasticity values obtained in this study correlate well with the square root of the compressive strength and it was found that this relationship holds true for all hydration ages investigated in this paper. Inverse analysis on the wedge-splitting test was conducted to determine the direct tensile strength. Values of tensile strength obtained from the inverse analysis have been validated numerically by carrying out finite element analysis on the wedge split, and anchor pull-out tests. The ratio of the tensile strength obtained from the inverse analysis to the splitting tensile strength was found to be in the range of 0.5–0.9 and 0.7 on average.

abstract: Periodic inspections in reinforced concrete structures are important to be carried out to assess their state of conservation. In this scenario, non-destructive tests can be a suitable option since destructive tests are invasive and may be difficult to be performed in some cases. Considering this option, correlations between non-destructive test parameters and the concrete properties to be analyzed are useful tools that make easier the structure inspection. In the present work, correlations between the compressive strength (fc) and splitting tensile strength (ft) and surface electrical resistivity (ρ) of concretes were studied. Brazilian concretes of six different mixtures were analyzed at five different ages and correlation curves between strength properties and surface electrical resistivity of concrete were obtained, which are represented by the general relationships fc= 14.18·ln(ρ) + 18.43 and ft = 0.69·ln(ρ) + 2.15 for compressive strength and splitting tensile strength, respectively. In addition, a general curve considering literature data and results from this work was proposed to represent the relationship between compressive strength and surface electrical resistivity - fc = 11.89·ln(ρ) + 18.90.

Explosive Spalling

An experimental research was performed on the compressive strength and splitting tensile strength for HSC with various polypropylene（PP） fibers after exposure to temperatures 300°C, 500°C, 700°C, 900°C. Cubes of 150mm×150mm were designed and fabricated with C60, blended with silica fume and slag, mixed with PP fibers, respectively. These specimens were naturally cooled to room temperature after being heated in an electric furnace. No explosive spalling was observed during the fire test on all HSC with PP fibers. From the results of nine types of concretes, both the compressive strength and splitting tensile strength of HSC with PP fibers decreased with the increase of temperature. Through a series of measurement, the relationships between the mechanical properties and the various PP fibers in HSC were analyzed, including the dosage and length of PP fiber. Based on the comparison in the experimental results, the proposed optimum of PP fiber in HSC was 1.5kg/m3 under the test condition. In addition, PP fiber with the length of 8mm could be more applicable to use.

Based on typical hydraulic engineering, difference of performances between full-graded and wet-screened concrete was studied. Results showed that owing to the gradation effect and skeleton effect of coarse aggregate and the size effect of specimen, full-graded concrete was 105%, 75%, 65% and 115% in compressive strength, splitting tensile strength, ultimate tension and compressive elastic modulus respectively, compared with wet-screened concrete. Under the same curing condition, compressive strength of wet-screened standard concrete specimen can represent the actual compressive strength of full-graded concrete.

The Relationship

Five engineered cementitious composite mixtures were adopted in this study with five different contents of 0, 0.5, 1.0, 1.5 and 2.0% of untreated low cost PVA fiber. Four different test specimens were prepared from the five mixtures to conduct several tests. Abrasion tests were conducted using 300 mm discs for six time steps each of 12 hours, while 100 mm cubes were used to evaluate the compressive strength. Cylinders with 100 mm diameter and 200 mm depth were adopted for splitting tensile strength, while four-point bending tests were conducted using small concrete beams with a span of 210 mm. The modulus of rupture was calculated from the tested beams, while the stiffness and elastic energy were calculated based on the load and deflection records of the beams. The tests showed that compressive strength did not affected noticeably by fiber inclusion, while all other mechanical quantities in addition to abrasion resistance exhibited significant improvement due to PVA fiber effect. The stiffness, splitting tensile strength, modulus of rupture and elastic energy exhibited maximum developments of 45, 134, 287 and 1181%, respectively, due fiber addition to the mixture. Quadratic formulas were found to be very accurate to correlate the relationship between abrasion depth in millimeters and each of splitting tensile strength, modulus of rupture and elastic energy, where R2 values of these relations were between 96.7 and 99.5%.
