Abstract

Corresponding data set for Tran-SET Project No. 18CASU03. Abstract of the final report is stated below for reference:

"In the way of finding sustainable development, the flowable fill is a relatively new construction technology. Flowable fill is a self-compacting material, which has been developed in recent years. Flowable fill has been used for different applications such as backfilling walls, sewer trenches, bridge abutments, conduit trenches, pile excavations, and retaining walls. This study examines the potential uses of Rice Husk Ash (RHA) as a sustainable cementitious material (SCM) in the preparation of flowable fill concrete. (RHA is an agricultural by-product of the rice milling process. This study has evaluated the usage of RHA in producing low strength and self-consolidating flowable fill concrete (FFC). Two different RHA samples (600 μm and 150 μm) in two different percentages (40%, and 60%, by the weight) of an Ordinary Portland Cement (OPC) have been used to prepare flowable fill mixtures. The evaluation processes of these FFC mixtures include determination of strength, flowability, unit weight, and air content in the laboratory. Test results showed that the FFC mixtures made with coarse RHA particles resulted in lower strength property compared to the regular FFC. On the other hand, the medium fine RHA particle was found to be effective in increasing the strength properties. Furthermore, a field demonstration has been conducted in this study to evaluate the workability, placement, and in-service performance of RHA modified FFC. Findings of this study will help the transportation and construction agencies in using RHA as a cost-effective construction material."
