Utilization And Mechanism Of Water Treatment Sludge In Mitigating Alkali-Silica Reaction (ASR) - Assignment Solution

Introduction 

The two cases selected for examination depend on experiments in order to obtain results that would complement the research paper. The researcher in both cases require high technical knowledge in order to decide what experiments should be considered so that the desired results can be obtained and tested for their feasibility. The first case title is “the effect of limestone mineral addition and cement kiln dust on the chloride ingress into mortar specimens made with cement, fly ash and slag” which researches on the ingress of chloride ions through concrete which ultimately effects the corrosion of the steel in reinforced concrete, this is done through experiment. The second case title is “Experimental and Finite Element Investigation of Rubberized Concrete Confined by FRP” which focuses on the fact that there is a lot of rubber wasted every year and for it to be utilized it can be converted into rubberized concrete, this study carries out experiments by changing the amount of rubber used in creating the rubberized concrete hence determining the best ratio. Both the cases require comparison of controlled experiments and given the topic of my study “Utilization and mechanism of water treatment sludge in mitigating alkali-silica reaction (ASR) in cement compost” the research methodology in these case studies would aid in finding the best scenario for mitigating alkali-silica reaction in cement compost. All three topics present a certain amount of legal bindings which would have to specifically studied in order to get the most usable results. Both the cases require the study of primary data which means that the collection of data to be analyzed has to primary for such cases. All three studies are linked to concrete which would provide me with a lot of material that can be related to my research.   

RESEARCH METHODOLOGY 

Reflection on the effect of limestone mineral addition and cement kiln dust on the chloride ingress into mortar specimens made with cement, fly ash and slag

As Tomm Benn, the author of the study, states the study was chosen due to an opportunity to increase the amount of chloride ions migrating into concrete using additional limestone material presented itself. There were two hypothesis of the study:

1. The increase of limestone mineral in concrete will allow chloride ions to migrate rapidly through the concrete
2. If cement was to be replaced by fly ash or ground granulated blastfurnace slag then the chloride ions migration would revert back to the initial level and there will be no problem with the increased addition of mineral in cement 

The research was quantitative in nature and required numerous concrete mixture to be made which spanned out for a year and then tested for compressive strength of the different mixtures, the second test was conducted to study the diffusion or ingress of chloride ions which was based on two different methods, after the chloride was diffused then the concrete was tested with and without the limestone mineral addition. After all the experiments the analysis is based on statistical and mathematical regression analysis which provides a through comparison between the different settings that were tested. Both the hypothesis were tested positive in the findings of the research. The data collected is primary as the experiments require testing and adding ingredients which are to be analyzed. 

My research topic relates to this case directly as both are experiments on concrete. To understand the mechanism water treatment slug in order to mitigate ASR (alkali-silica reaction) in cement compost there will have to be a quantitative study in order to test the effects of different conditions and ratios of ingredients applied to test how the ASR can be reduced in cement compost. The above mentioned case required researchers to be able to comprehend the technical side and in order to understand what experiments should be tested my research would require through knowledge about the matter. These experiments would last at least 6 months under controlled environment to start the analysis which would be based on the comparison of the results of the effects on the ASR under different conditions. The findings would be recorded using statistical analysis that would best fit the study. The method of collecting data to analyze the research question would be the same as this case study as the data is dependent on the results of the findings of the experiments.
