Abstract
This paper aims to produce a new concrete that combines the benefits of self-compacting concrete (SCC), polypropylene fiber (PPF), and magnetic water (MW). Slump flow, L-box, V-funnel, compressive strength, split tensile strength, and flexural strength approaches were performed to investigate the fresh properties and mechanical behavior of concrete. Various percentages (0.4%-1.2%) of self-compacted agent (SCA) and different percentages (0%-0.5%) of PPF by weight of cement were adopted. The results showed that 0.8% SCA magnetized concrete had very similar fresh properties to 1.2% SCA nonmagnetized concrete. This led the author to believe that using MW as an alternative to ordinary tap water in the manufacture of SCC has promising benefits, the most important of which is reducing the used dosage of SCA by approximately 33.3% (from 1.2% to 0.8%), resulting in a lower cost of production of such type of concrete while retaining the same workability. The optimum percentage of PPF to be used in magnetic and nonmagnetic self-compacting concrete is 0.35%.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
