Optimizing Porous Concrete Using Granite Stone Crushing

The compressive strength of porous concrete made with granite screenings 5 mm was found to be higher than that of concrete made with granite crushed stone 5 10 mm For instance at a water/cement ratio W/C of and cement paste layer thickness CPLT of 150 microns the strength of concrete with granite screenings was MPa

Weakening of Compressive Strength of Granite by

Numerical simulations predict that the weakening effect on compressive strength of granite is 10% with the excitation frequency and voltage of kHz and 150 kV of the pretreatment As the weakening effect takes place at a natural frequency of the numerical rock sample the quartz content has only a slight effect on the frequency at which

Aging and Curing Temperature Effects on

The Materials Specifications put forth minimum values for compressive strength for each stone type; for example at least 1 800 psi MPa for marble and 19 000 psi 131 MPa for granite Compressive strength—or the load at which the stone fails—is usually much higher than the actual load the stone must resist The industry has

Predicting the unconfined compressive strength of granite

This paper reports the results of advanced data analysis involving artificial neural networks for the prediction of the unconfined compressive strength of granite using only two non destructive test indexes A data independent site independent unbiased database comprising 182 datasets from non destructive tests reported in the literature was compiled and used to train and develop

Prediction of uniaxial compressive strength of rock based on

Abstract Rock uniaxial compressive strength UCS is one of the most important mechanical parameters of rock which is vital to the design of rock engineering and stability analysis of country rock Since the rigid procedures of rock drilling and coring sample processing and testing conditions in rock UCS test a high precision model is urgent required for rock UCS prediction

Uniaxial compressive strength measurements of limestone

In many geo engineering fields the uniaxial compressive strength UCS of a rock material is the parameter most commonly used to define a rock s mechanical strength Several international standards have been developed for determining this value which require the tested material to have certain minimum dimensions and shapes In many applications however

Geotechnical study of marble schist and granite as dimension stone…

Granite has a lower compressive strength than the ASTM specification so it should be avoided for load bearing masonry units and external pavements Granites and marbles have a higher degree of water absorption All three rock units have a very high degree of polish so their use as decorative stone especially as internal flooring and at
