Abstract (300 words maximum)
This experimental study will present the data generated from several sets of tests of Portland Cement Concrete (PCC) mixed with recyclable waste materials, specifically Fly-Ash Type F (FATF). The first set of data will be from partially replacing fine aggregate with FATF and the second set of data will be from partially replacing cement with FATF in PCC. During this experimental study, concrete samples (4-inch diameter and 8-inch height cylinders) will be cast for both the sets. In the first set fine aggregates will be replaced by FATF at four different levels (5, 10, 15, and 20% by weight) and cured in water for periods of 7, 14, 28 days. While in the second set, cement will be replaced at four different percentages (10%, 20%, 30%, and 40% by weight) for the same environment and curing periods. The slump will be measured during the casting of the concrete samples for all mixes in order to help understand the workability of the PCC. The development of compressive strength and resistivity in each sample will be measured after each curing period to understand the strength and durability of the PCC. The strength, workability and durability will be compared with control data. It is expected that the PCC mixed with FATF will have the same or higher strength, workability, and durability than that of control PCC. It is also expected that there will be correlations of strength with resistivity. The test data will enable us to determine the optimal amount of FATA to replace fine aggregates and cement in the PCC mixes. The advantages of using recyclable FATA in PCC mixes include reducing the amount of waste material that goes to landfills, and cost savings, by preserving the virgin raw materials.
