Bedrock unconfined compressive strength (UCS) is a key parameter in designing thegeosciences and building related projects comprising both the underground and surface rock structures. Determination of rock UCS using standard laboratory tests is a complicated, expensive, and time-consuming process, which requires fresh core specimens. However, preparing fresh cores is not always possible, especi...

Accurate assessment of the subsurface mechanical characteristics and how they correlate with dielectric properties is crucial to optimize future drilling and sampling investigations on planetary bodies. For 12 different types of basaltic rocks with different hardnesses, we use capacitive cells to measure the real part of the dielectric constant over the frequency range 100–1000 MHz, and a Schmi...

This study aims to evaluate concrete having Waste Marble Powder (WMP) as partial replacement of cement. is the metamorphic form limestone (CaCO3) and WMP was chosen substitute cement on account its high calcium oxide content. by-product marble industry an environmental burden. The manufacturing also environmentally hazardous owing emission greenhouse gases. Thus, recycling in place offers two e...

Abstract Small historical churches in rural villages are mainly functional buildings, lacking spectacular architectural or ornamental features. This is also true for the St. Johannis Chapel Lütgenrode near Göttingen (Lower Saxony, Germany), which dates back to 13th century. The use of ca. 10 different natural building stones (Triassic sandstone and limestone, Holocene fresh water carbonate), sc...

Uniaxial compressive strength (UCS) is considered to be one of the important parameters in rock engineering projects. In order to determine UCS, direct and indirect techniques are employed. In the direct approach, UCS is determined from the laboratory UCS test. In indirect techniques determine UCS based on the nondestructive test findings which can be easily and quickly performed and require re...

The application of the neuro-fuzzy inference system to predict the compressive strength of concrete is presented in this study. The adaptive neuro-fuzzy inference system (ANFIS) is introduced for training and testing the data sets consisting of various parameters. To investigate the influence of various parameters which affect the compressive strength, 1551 data pairs are collected from the tec...

Abstract Quality of concrete is mainly measured by evaluating its strength. Destructive testing specimens used for the purpose. An alternative to it non-destructive testing. This research work presents cylinders made using partial replacement natural coarse aggregates with old as and exposed 6-hour fire at 1000ºC. Rebound hammer in this evaluate 240 are cast 1:2:4 mix 0.54 water cement ratio. A...
