Data for the physical and mechanical properties of staple fibers cement paste composites.

The data presented herein are compiled of the research summary of "Staple-wire-reinforced high-volume fly-ash cement paste composites" (Aydin, in preparation) [1]. This data article provides general information about the novel high volume fly ash cement paste composites composed of various volume of staple wires. The dataset here also helps the readers to understand the mechanisms of staple wires on physical and mechanical properties of pure cement paste composites.

Data

The dataset presented herein were obtained from the physical and mechanical tests for various volume proportions of staple wire fiber blended with high volume fly ash (HVFA) and cement. The data provides in this article composed of pure cement paste composites. The detailed of the dataset presented here can be found in [1]. Additionally, the existing models proposed by others [2], [3] were used to check the applicability for staple wire HVFA cement paste composites. The regression analysis of test data for 336 samples were used to predict physico-mechanical properties of the staple wire-reinforced paste composites.

Experimental design, materials and methods

The water-to-cement (w/c) ratio was kept constant at 39.5% for all mixtures, as optimized in a previous research [4], [5]. The data presented here examined 80% fly ash, 20% cement, and staple fiber ranging from 0% to 3.5% by volume of paste. Different HVFA cement paste mixes were experimentally examined, and mixes which showed the best performance were chosen for the previous research [4], [5]. Composites were cast in 50 mm cubic molds and 40 mm×40 mm×160 mm prismatic molds. Previous equations for spacing proposed by other researchers [2], [3] have been used to check their validity of volume of staple wire fiber of high volume fly ash cement paste composites. Additionally, based on the ACI report [6] and ASTM standards [7], [8], alternative areas of application of this composite in construction section were investigated. The detailed of mix proportions, experimental setup and results can be found in [1] (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9)
