ELASTIC PROPERTIES OF ROCKS. The aim of this paper is to determine the elastic parameters of some rocks and especially limestones, schist, sandstones, conglomerates, peridotites and granites using a large number of laboratory tests performed on intact rock samples. The range of values for Young`s modulus and uniaxial compressive strength is...

Basalt fibres are characterised by high tensile strength from about 1700 MPa to 4800 MPa, see Table 1. Tensile strength of 4800 MPa is higher than of steel fibres, high Emodulus is 90. GPa, melting temperature equal to 1450 °C, high resistance to fire as well as to nuclear and ultraviolet (UV) radiation.
The basalt fibers typically have a filament diameter of between 10 and 20 µm which is far enough above the respiratory limit of 5 µm to make basalt fiber a suitable replacement for asbestos. They also have a high elastic modulus, resulting in high specific strength —three times that of steel .
elastic modulus was MPa, GPa respectively. Scalici et al. [14] evaluated the mechanical properties of quasiunidirectional basalt fabric reinforced with epoxy resin. Longitudinal Young's modulus and strength values were found to be increased by 7% and 10% when compared to RI and VB techniques respectively.

shows considerably better elastic properties than the 'only fiber' basalt (note that the elastic modulus of the basalt fiber is about 11,000 kg/mm2, while the carbon fiber is kg/mm2). However, the glass fiber (Wallenberger et. al., 2001), for its shape and chemical composition, can be considered as
Jan 13, 2008· For CMU, the modulus (in compression) is generally taken as 900 f'm. typical masonry strengths run from 1200 to 2000 psi. all of these values can vary greatly. I recommend the code (ACI 530) or look for the TEK manuals from those are free and very informative. HTH

Elastic modulus Wikipedia. An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically ...
Basalt is a good candidate for fiber reinforcement due to its high elastic modulus, heat resistance, and acoustic dampening. [8] The literature gives tensile strength values from 1500 to 4000 MPa and operating temperatures around 800°C. Above this, degradation begins to occur. The melting point of basalt is around 1400°C.
In this paper, a micromechanical model is implemented in software for the prediction of local mechanical properties of discontinuous short fiber reinforced composites. The model, based on the Mori and Tanaka method, shearlag, computational model, NielsenChen model and Miwa's model is used to predict the elastic behaviour of basalt short fiber reinforced with Al alloy composites.
Young's modulus of basalt fiber varies between 78 and 90 GPa for basalt fiber from different sources. Compared to glass, most references claim that basalt fiber has higher or comparable elastic modulus and tensile –15 Besides their good mechanical properties, basalt fibers have .

modulus of elasticity. In this study the authors adopted the conventional form, in which modulus of elasticity, E, is expressed as a function of compressive strength a and unit weight,. Since it is selfevident that the concrete with a compressive strength of 0MPa has modulus of elasticity of 0MPa, the basic form of the equation is expressed as

"Elastic modulus" is a material property that indicates the strength or elasticity of the steel materials used for making mold parts. The elastic modulus is also called the "Young's modulus" usually. The elastic modulus is the coefficient of proportionality between the "strain" and the "tensile stress" when the steel material is pulled.
Research results show that the performance of dynamic modulus of elasticity and quality loss of basalt fiber concrete in freezing and thawing process is obviously better than the plain concrete. The dosage of % basalt fiber concrete freezingthawing resisting performance is the best in the four groups of concrete samples.
