Data for the physical and mechanical properties of high volume fly ash cement paste composites.

The data presented herein are compiled of the research summary of "Characterization of High-Volume Fly-Ash Cement Paste for Sustainable Construction Application" (Aydin and Arel, 2017) [1]. This data article provides general information about the ASTM Class C and Class F fly ash cement paste composites composed of silica fume, lime, water reducing admixtures in three different level of workability (0 mm, 100 mm and 200 mm). The dataset here also helps the readers to understand the links with the basic properties of the ingredients, for example, how can porosity be predicted based on the mixture design? how can the strength of the material be linked with the basic strengths of the constituent ingredients?.

Data

The dataset presented herein were obtained from the physical and mechanical tests of various amounts of ASTM Class C and Class F fly ash, silica fume, lime and water reducers to produce high volume fly ash (HVFA) cement paste composites. 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 in previous studies for mortars and cement paste [2], [3], [4], [5], [6], [7] were used to check the applicability in controlled low strength applications. The regression analysis of test data for 1512 samples were used to predict the effects of mixture ingredients in those applications to exhibit novel mixture design methods (Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, Fig. 9).

Experimental design, materials and methods

The water-to-binder (w/b) ratio was adjusted to attain the required workability. This article investigates three workability range (0 mm, 100 mm and 200 mm) and seven mixture groups. The groups are all optimized in a previous researches [2], [3], [4], [5]. The data presented here examined the mixture ingredients of fly ash, cement, silica fume, lime and water reducers. The seven hundred fifty six samples for each type of fly ash class are used. Various HVFA cement paste mixes were experimentally examined and 1512 mixes are evaluated. Composites were cast in 55 mm by 110 mm cylindrical molds and vibrated through vibrating table. The produced samples were tested in 7, 28 and 90 days. The detailed of mix proportions, experimental setup and results can be found in [1].
