The polycarboxylate superplasticizer was used in mortar and concrete, of which the solid ratio was 40% and water reduction rate was 37%.
Since the density and specific surface area of rGFRP (1.71 g/cm3 and 1.59 g/cm3) was lower than silica sand (2.65 g/cm3), large substitution of sand with rGFRP resulted significant reduction of mortars’ density.
In addition, the difference among all the detection points for each sample set was amplified, in term of the increased standard deviation of each data set, as illustrated in Fig. 11.

The reduction in TPC amount in UCOL is much pronounced compared to COL30 and COL50.
The results point out that the reduction in the antioxidant activity of olive oil sample kept in uncoated glass tubes occur more rapidly compared to those kept in coated tubes.

The final height reduction was 70%.
The raw data of stress-strain was obtained in the process of thermal compression test.
Meanwhile, the formed dense and continuous oxide scales could inhibit further oxidation, which resulted in the reduction of inward diffusion of oxygen molecules and outward diffusion of alloying elements [30].

As the reduction in free volume with PCL (with a lower WVTR) and reduction in the interconnection between the free volumes/voids, which resulted from the interactions of the polymer chain of PBS-PCL through hydrogen bonding, analyzed by FTIR studies[5], the PBS-PCL blends have low WVTR.
However, data on biodegradation of PHB and PHB-PCL blends in compost medium at ambient temperature was unavailable in the literature review.

Compared to conventional concrete, GPC exhibits significantly lower CO2 emissions, with reduction rates ranging from 9% [16] to over 80% [17].
CFRP bars are generally 4 to 8 times lighter than steel bars, making them an excellent alternative for applications where weight reduction is crucial, such as bridge construction and high-rise buildings [71, 72].
Also, the reinforcement ratio positively impacted the load capacity and the deflection reduction.

The article presents experimental data obtained during the use of powdered calcium stearate and its suspension as bulk water repellents for fine-grained concrete.
The introduction of calcium stearate, both in the form of a powder and in the form of a suspension, led to a significant reduction in the size of the capillary pores.
