Each type of cement was mixed into three dosagesof recycled aggregate 0%,
25% and 100% as replacement of natural coarse aggregate. The specimen test is
cylinder form 7.5cm in diameter and 15cm in high. The 27 samples were tested by
immersion test while 9 others without immersion test.The researcher has cured 27
concrete samples in (H2SO4) 5% and the other concrete samples cured by air. After 28
days of age, the compressive strength test for both the samples which immersed in
solution and by air was conducted. The process continued to the renewal of solution
and measuring weights and diameters of the other samples in the solution every 2
weeks. After 56 days of age, the compressive strength test was conducted. Finally, the
small portions of the surfaces and core of the samples were tested using XRD.
It is noticed from compressive strength result the samples which cured by air
gave better result than others which cured by solution. The higher percentage of
recycled aggregates in the concrete means the less in compressive strength and less in
resistance to acid attack. It is noted that mixtures which contain PPC are the most
resistant to acid attack. Mixtures which contain PCC rank number two related to the
resistance to acid attack. The mixtures which contain PPC have retained their size
throughout the duration of curing.
Keywords. Recycled aggregate, Deterioration, Sulfuric acid
