The calculations of the mixture design of concrete have been widely performed according to the compressive strength or tensile strength. However, a cracked concrete/reinforced concrete structure can only be simulated by using the principles of fracture mechanics. The purpose of this study is to obtain certain expressions based on the properties of ...

Rice is one of the most commonly consumed grains. It could be a good source of nutrients in a diet, but its consumption could also contribute to exposure to toxic elements. All rice products available on the Polish market are imported, which may pose a particular concern as to the safety of their consumption. The aim of our study was to estimate th...
Abstract The objective of this study is to analyse the use of binary mixtures of pozzolanic materials and concrete demolition waste in concrete mixtures, especially the resulting mechanical properties and durability. A total of ten concrete formulations were produced distinguishing them in different types using different Portland cements, different...
Existing reinforced concrete (RC) structures can be strengthened using Strain Hardening Cementitious Composites (SHCC). The ability of SHCC in exhibiting a ductile response under tensile load due to strain-hardening after crack initiation makes it a viable material to be used in, both, construction and retrofitting of concrete structures. The main...

The emergence of waste tire steel fiber (WTSF) which is an undervalued resource was borne out of the need to extract the useful materials in waste tires considering the sheer volume of this resource that is disposed of in landfills globally. These fibers find applications in tunnel linings, hydraulic structures, bridge decks, pavements and slope st...

Laminaria japonica is widely cultivated in East Asia, including South Korea. Fucoidan, a main component of L. japonica, protects neurons from neurological disorders such as ischemia and traumatic brain injury. In the present study, we examined the effects of extract from fermented L. japonica on the reduction of proliferating cells and neuroblasts ...

This paper presents the results from the experimental investigation of the use of wheat straw ash (WSA) as a partial replacement of Portland cement in concrete mixtures. The WSA was used to replace PC up to 20% and the corresponding mechanical performance of the concrete mixtures evaluated. The mechanical performance of the concrete mixtures was ev...

Concrete is a building material consisting of a mixture of gravel, sand, cement, and water. It is one of the most widely used materials on earth. The concrete industry generates harmful effects on the environment. The cement industry is a testimony to the air pollution generated by greenhouse gases. The use of mussel shell waste as a substitute for...

Sulfate attack on concrete structures is a major durability concern wherein concrete interacts with marine water, swamp water, groundwater, sewage water, freshwater, etc. In this study, the supplementary cementitious materials such as fly ash (FA) and nanoparticles are together incorporated into conventional concrete aiming to enhance the resistanc...
The objective of my senior project is to find a solution for the growing amount of improperly disposed cigarette butts on our planet. To accomplish this, I created and tested concrete cylinders mixed with different amounts of used cigarettes. It is my goal that we will be able to recycle cigarette butts and incorporate them into our everyday concre...
