An experimental investigation was conducted to evaluate the compressive, tensile strength and modulus of elasticity of two-stage concrete (TSC) at different water-to-cement ratios. The primary objectives were to measure the elastic modulus, compressive strength and splitting tensile strength of TSC and to determine if there is a quantifiable relationship between compressive and tensile strength.

The accuracies of prediction by experimental data obtained in laboratory as well as by EN 1992-1-1, ACI 209 and SRPS U.M1.048 are compared on the basis of the coefficient of determination.

Learn MoreNov 24, · The cubic compressive strength, splitting tensile strength, and flexural strength of SAP concrete with different internal curing water-cement ratios was obtained. The converting relationships between the internal curing water-cement ratio and different

Learn MoreThe tensile strength of concrete is approximately ten times less than its compressive strength. 2.Testing methods. Compressive strength is determined by crushing cubes or cylinders to failure. Tensile strength is measured by the splitting test or the flexural test. The spread of strength results of samples taken from nominally the same concretes is assumed to approximate to the normal

Learn MoreSimilarly to obtain a relation for determining the compressive strength of concrete through UPV a graph shown in fig. 6 has been plotted between the Velocity (V) from UPV (m/s) and the Actual Compressive Strength (f) - Relation obtained between the UPV (V) and the actual Crushing strength (f) of concrete is shown in eqn. 2 y = 0.004x - 1.3516

Learn MoreFew studies have been carried out towards investigating the relationship between the split tensile strength and the compressive strength of SFRC. The available relationships are either based on limited number of specimens or narrow range of fiber content or fiber aspect ratio. Ashour et al [7] suggested the following equation for high strength concrete specimens of a single aspect ratio, l/d

Learn MoreThe testing content considers the 28-day compressive strength, split tensile strength, and flexural strength tests of rubber fiber concrete. According to the mix ratio of each group listed in Table 5 , the rubber fiber concrete specimens were prepared by referring to "Standard for Test Methods of Mechanical Properties of General Concrete" GB/T 50081-2016.

Learn MoreAnalytical models for compressive strength and tensile strength of high performance concrete are presented. High performance concrete was developed using binary and ternary blending combinations consisting of ordinary Portland cement, pulverised fuel ash and silica fume. Pulverised fuel ash and silica fume were incorporated as partial cement replacements for the preparation of various

Learn MoreUsually, the compressive strength of concrete varies from 2500 psi (17 MPa) to 4000 psi (28 MPa) and higher in residential and commercial structures. Several applications also utilize strengths greater than 10,000 psi (70 MPa). Tensile Strength Of Concrete; The tensile strength of concrete is its capacity to resist cracking or breaking under

Learn MoreAug 08, · The comparison between the relation of abrasion to compressive strength and abrasion to flexural tensile strength, made in terms of R 2 of the linear regression on log scale, showed that a stronger relation existed between abrasion and flexural tensile strength than between abrasion and compressive strength of the concrete containing either fly

Learn MoreTensile and compressive stresses are two types of stresses a material can undergo. The type of the stress is determined by the force being applied on the material. If it is a tensile (stretching) force, the material experiences a tensile stress. I

Learn MoreThe study examines existing, commonly accepted 0.5 power relationship between compressive strength (CS) and splitting tensile strength (STS) in cement concrete and investigates its applicability to geoploymer concretes. Two types of systems were studied; one using ASTM class F flyash in place of cement and the other replacing sand with

Learn MoreTests such as this one are the standard way of measuring the tensile strength of concrete. This test is intended to show students: Concrete is brittle in tension; Concrete has a low tensile strength compared to its compressive strength; Application of a compressive force can cause cracks to open up in a perpendicular direction; At the end of the video a graph of vertical load versus vertical

Learn MoreFig. 1 shows typical compressive and tensile stress-strain relations of one of the UHP-FRC materials developed at UT Arlington. The maximum usable compressive strain (at a post-peak stress of approximately 80% of the peak stress), εcu, is approximately 0.015. For plain concrete, the compressive strain at this level of stress is 0.003. ACI 318 (ACI, ) and AASHTO LRFD (AASHTO, ) use 0
