The purpose ofˑthis study is to evaluate the density and compressive strength characteristics of pure gypsum in order to ascertain the extent to which the use of Carbon-Fiber-Chopped (CFC) has an impact on these parameters. When dealing with gypsum in its purest form, four distinct combinations were used. As a result of the fact that the proportion of water to pure gypsum in the combinations is either 0.55 or 0.65, the combinations are separated into two different groups. Using the volume fraction ( Vfˑ) of 0.0 % and 0.4 % of CFC (pure gypsum with and without fibers), each group set is split into two unique groups. These groups are based on the volume fraction. Three samples, each measuring 5 centimeters by 5 centimeters by 5 centimeters, were employed for each admixture. Increasing and enhancing compressive strength for two distinct water / pure gypsum ratios (Wˑ/ˑPG) has been shown to be attainable by the use of CFC in pure gypsum mixtures. This was demonstrated on two separate occasions. Compressive strength grows at a pace that is directly proportional to the W/PG ratio, which is directly tied to the rate at which CFC is applied. When compared to the ratio, this rate is precisely proportional to it. It is also essential to keep in mind that an increase in the W/PG ratio results in a decrease in both the density and the compressive strength of the material. Regarding this particular matter, it is important to take it into mind. On the other hand, the be- havior of pure gypsum (with CFC) results in a decrease in the drop rate of decline in both density and compressive strength concurrently. This is as a result of the reaction between the two properties.
Key words: Carbon-Fiber-Chopped (CFC) / Pure Gypsum (PG) / Water/Pure Gypsum(W/PG) ratio / Compressive Strength / Density / volume fraction of CFC (Vf)
