“…Because pozzolans (cement substitutes of PSA) could reduce damage due to high temperatures in concrete parts exposed to high temperatures after completion of the curing process [28], the compressive strength of SCC containing 10% PSA was higher than its non-PSA counterparts. The increase in SCT also caused a decrease in the mass of SCC and PC performance, thereby reducing the compressive strength of concrete [29]. The higher the SCT and the longer the heating process can cause the concrete matrix to become more brittle and reduce the compressive strength [30].…”

Self-Compacting Concrete (SCC) is proven as durable concrete and applied to constructions. In this paper, a study was conducted to analyze the influence of variations of steam curing temperature (SCT) and water/binder (w/b) ratio on the characteristics of SCC incorporating 10% Palm Shell Ash (PSA) as a partial substitution for cement mass. The SCT was arranged from 25 C to 80 C. The variation of w/b in the compositions of SCC was 0.325, 0.350, and 0.375. The results showed that using PSA, the variation of SCT and the w/b ratio influenced the workability of the fresh concrete. The PSA, SCT, and the w/b ratio affected the concrete compressive strength and mass density. The increased SCT caused a lighter density and greater compressive strength. However, the decreased compressive strength occurred due to an excessive SCT of 70 C and above. The SCT of 60 C, 10% PSA, and w/b ratio of 0.350 in the mixture produced the greatest compressive strength of 36.27 MPa at 28 days of age, while without SCT, the greatest compressive strength of 36.78 MPa was achieved at the age of 28 days containing 10% PSA and w/b ratio of 0.325. It indicated that the w/b ratio was more influential than the SCT on the increase of the SCC compressive strength.

“…[6] Studies showed that the compressive behavior of PC containing resin increased with increasing resin content, while the tensile behavior remained almost abiding and the yield point strain for PC was approximately doubled or tripled as the OCC. [7,8] Also, various studies have been conducted to investigate the microstructure, thermal, and mechanical properties of epoxy resin composites for coating applications. [9][10][11][12] Verma et al [13] performed a study to fabricate and characterize the carbonaceous filler modified epoxy resin composites with three filler content (5,10, and 15 wt%).…”

This study aims to assess the mechanical properties of polymer composite (PC) reinforced by introducing two types of synthetic fibers including polypropylene (PP) and polyvinyl alcohol (PVA). The optimum amount of resin was evaluated through mechanical tests. Then, selected fibers were added to the optimum mix in three fractions (0.5%, 1%, and 1.5%) by the weight of the binder. Various properties of PC which are density, compressive strength, flexural strength, modulus of elastic, and water absorption were appraised for all mix combinations after different curing times (1, 3, 7, and 28 days) beside scanning electron microscopy analysis for microstructure observation. Experimental outcomes revealed that by rising the PP fiber content, the mechanical strengths of fiber-reinforced polymer composite (FRPC) were ameliorated, where compressive and flexural strength grew 58.14% and 78.31%, respectively, at the highest fiber ratio (1.5%) compared with the plain PC. On the other hand, PC reinforced by PVA fibers represented an inverse behavior that by ascending the fiber fraction, reduction in the properties of FRPC observed.
