Mechanical and maintenance of white cement based mortars ceramic waste and durability performance effect of fiber use

This research aims to examine the changes in the properties of White Cement mortar in which ceramic waste powder is partially included in the mixture. The materials used in construction are constantly improved, taking into account economic and environmental factors. Using ceramic waste powder as a partial additive to White Cement mortar is one of the ways to improve building materials that reduce environmental pollution by reducing cement production, which is one of the sources of pollution. 5%, 10% and 15% ceramic powder substitutes and 0.4% different fibers (brass coated steel fiber, basalt fiber and hooked end steel fiber) were added to the White Cement mixture. The compressive strength and flexural strength of these samples were examined to verify the advantages and disadvantages of the mixtures used. In addition, high temperature, freeze-thaw and sulfate effects were applied to the samples and the changes in physical and mechanical properties were examined after 90 days. In general, the results show that the addition of ceramic waste powder will increase the compressive and bending strength of the mixture; It was determined that the addition of 5% ceramic waste powder gave the maximum strength among the additional amounts; It shows that increasing the addition percentage will cause the strength to decrease. However, it is still higher than the strength of the White Cement mixture without the addition of ceramic waste, and the addition of more ceramic powder disrupted the homogeneous structure of the sample and reduced its compressive and bending strength.
